[@jamesreid679]

I came here hoping to learn something on designing a box and this all went over my head lol

[@dillonkoch72]

Yeah im in the same boat as you lol

[@situationunchanged9733]

+1 same ✈ 🤯

[@prithvirajjadhav5500]

No,listen him carefully n watch some designs you can tell the difference 😉

[@user54389]

OK. I did IASCA back in the 90's, and currently do live sound and production. I understood about 30% of what you were talking about...you are on some next level shit sir. I'm going to go retake physics and see if I can hit 50% :D

[@VentureWelding]

This guy is the godfather of audio. I'm not easily impressed, but this guy is on point, definitely KNOWS the industry..

[@elephant1851]

I'll remember this day when I discovered a channel that was miles ahead of any other when discussing enclosure design. I don't even know what he's talking about half the time!

[@smigletat9634]

Hybrid Bass Reflex Transmission Line T-box... Great guy designed this for me nearly a decade & a half ago! Hats off to you Pete!! Most underrated audio enthusiast on the internet.

[@Basshead6400]

I miss watching your old build vlogs in the wood shed outback and everyday life vlogs from like 4 years ago. Will they ever be made public again ? Perty plz - lots of love from Denmark 🇩🇰

[@Basshead6400]

HexiBase , Very glad to hear. I’ll be watching every single video with great interest. Also, a guy in the comments, mentioned an idea about you reacting to some extreme builds. Such as Brazilian treme treme and Russian builds and so on, would loooove to see reaction vids and brief explanations of such an subject. Just my 2 cents (:

[@Rorali3]

I made an isobaric clamshell in a bandpass several years ago, using some 10$ DUAL brand subs. Total enclosure size was very small. I built it for kicks and used a cheap plate amp from Dayton, I could barely hear it, however the next door neighbor came running over because she thought there was an earthquake from all the pictures rattling on her walls. I love enclosure design and seeing how speakers respond to different boxes. Specially full range cones like Fostex

[@Flukeful]

Pete designed my rear loading horn. its so efficient doesn't need that much power to go loud. I am happy that he is back doing what he does best. thanks Pete!

[@Spoolingturbo6]

I'm inspired everytime I watch your videos. My brain gets going in all different directions. I come up with wild stuff like the 4th/8th slot port transmission line folded horn x) I really want to do something for my boat. And need to stop kicking around ideas, pick one and just do it.

[@stinkyarmpitbass6259]

OMG. I never get tired of learning from your videos!

[@rakkup7572]

One of the most interesting enclosures for car audio I’ve had the pleasure to sit in front of quite a few times was 4- JL audio 10’s In isobaric configuration, in a full plexiglass box with plexiglass ports. It was in 1992, it was beautiful, and it was LOUD.

[@JustinKirby]

I follow a few different car audio guys here on KZbin - Soundman, EXO, Five Star, SMD and the like (and they are all great in their own right), but to round all of them out with the engineering point-of-view of HexiBase....nothing else is needed. I didn't understand 90% of what this video talked about, but yet the way it was all explained, the video ended and I felt like I understood all of it. It's weird. I subscribed. My level of understanding is "throw subs in a box and crank that shit to 11." Hexi goes into extreme detail on how you can do much more with much less. How could you not respect that?!

[@beerman9807]

Mr Meade is smart , those enclosure are way bigger so he goes with ported or vented same thing, he knows his stuff

[@wolfman5494]

Holy balls I've never been so hosed down by engineering info about sub boxes. Usually, its some dude tripping over his words, dropping tools while trying to hold the shaky camera, putting together whatever will make the windows explode quickest. Badass vid!

[@_Diggler]

This by far one of the most fascinating channels I’ve come across. Hexibass knows his stuff. I’ll keep scrubbing the channel and building my knowledge so I can someday understand the nuances of what’s going on here. I came across the channel while doing research for 3D printing. 👀 i aspire to rework my home theater set up soon.

[@djijspeakerguy4628]

The most unique speaker box design I’ve ever seen was actually a dual 18” pro audio subwoofer enclosure. It was essentially a 6th order bandpass with 3 separate chambers, one for the back of each driver, and the third for the front of both drivers, which were facing each other in the back. The middle chamber was tuned much higher, and used a strange port/horn hybrid design that opened to the front center of the enclosure. The two side chambers had large ports on either side. I heard 12 of these boxes playing at once at an outdoor festival last summer, and the SPL was absolutely nuts, even from approximately 200 feet (around 60 meters) back! My entire body was vibrating enough to blur my vision, and they seemed to go pretty low (for pro subs, that is.) If anyone’s curious, the manufacturer was D&B Audiotechnik, which is a common name in major music festivals and tours. Their B2 and newer B22 subwoofers use this design, and they might just be my favorite pro subs in production. There are a few diagrams of the box design online.

[@JAMPROSOUND]

The Thigpen rotary woofer is the craziest driver I've ever seen personally. I sat through two demos and to this day, have yet to experience anything as noteworthy. Your videos are always great!

[@wdbaudio]

Brilliant and informative video as ever! I particularly like the little enclosure animations for each example

[@prodbyjxshy1300]

Wow I had no idea that there are that many enclosure designs. Thanks for the information.

[@bringmeyourweak]

Amazing video topic Pete! Glad to see you guys around again.

[@flowleopard893]

Very happy to find this channel. Good eye opening info. Been in love with my horns for too long this video inspired me to get back to research. Thanks so much.

[@RinksRides]

I thought I was good at building enclosures.. What I just witnessed was alien technology! All bow to the HexiBase! Also Subbed!!!!!

[@ostelo84]

Same here I instantly subbed lol

[@supersteveenglish7340]

You still haven't seen anything. Those are just virtual renditions of a few semi-fancy ones he's done. Find the vid where he goes into the effects of the car's shape on the response curve at target listening position.

[@SyberianWulff]

they say, never turn hobby into a occupation, but damn, i wish i knew even half of what you know. kick all the compo taxi's to the curb. Subbed.

[@rapdfyr1]

good info ! this video brings me back to my old days of building Exotic and impressive smaller woofer enclosures. I loved the looks and compliments I got from people hearing 2 6x9 's in a Dual Chambered Tri-Tuned Bass Reflex Enclosure . I had to build it with a plexi face to prove there were no other subs hidden inside.

[@zyglog]

I spent a few years playing with full range drivers. I doubt that I will ever have the chance to hear a Hedlund Horn. I have always been fascinated by the design and beauty of this speaker.

[@MansaMarMusic]

we want hours of this pleeease🤣

[@stealth418]

Your videos are incredible. You're very well spoken.

[@anthonylee7263]

These are the most impressive enclosure ideas I've seen since I got into installing my own car audio from early 1980's.

[@joramvandervorst7715]

The most amazing thing i heard are open baffle speakers, first the Linkwitz designs, then Pure Audio Project and finally the best i ever heard was the Daudio W1 speaker, Mundorf AMT, Acoustic Technology mid and double Seas 10” in a W-frame below, pure magic!

[@GuyFromJupiter]

I understood virtually none of this, but it all sounds pretty cool.

[@jus1taj]

Yeah, these look amazing. I really don’t understand most of what you talk about but I’m learning.

[@LitoGeorge]

High quality video, with interesting designs explaining things I've read about on plenty of focused DIY forums. Thank you. New subscriber.

[@gabrielkardos4342]

I love how detailed you are in your videos... thank you for providing great information!

[@matyi1656]

I wish I could understand everything you say

[@gchonde]

Me too

[@dennis3004psp]

I have no idea what I need for calculation.

[@kafklatsch3198]

An accent for sure, but I do understand every single syllable without issue.. hmmmm..

[@correokel]

Mee toooooo

[@3hub5386]

It's called "listening " sure you had a problem with that for a long time before the video 😂

[@charliefrancis6438]

Wow this popped up in my KZbin feed , and this is my new favorite channel, I love learning about exotic enclosures designs , keep up the great work, I also have been building subs since 1994 was my fist serious build in which I did a 4th order bandpass with 6 15 inch Orion xtr2 , hit a 151.6 dB with a 1000 watts, and I was hooked ever since 👍🏻

[@pgmurray76]

Holy crap! Similar story and time period here too! Below is a cut and paste of what I added to FREDDIE ROSS' question above. I still remember pedalling a bicycle at least 15 miles in 1993 to Star Car Audio in Brick NJ to see the Orion demo Astro van. Six XTR 15's powered by three of their longest amplifiers. First time in my life a system rattled my teeth and made my tshirt flap around. The side door and windows were wide open too. I was only on the step of the sliding door. I tried to put 4th order bp in anything big enough after that. The design with the most improved, loud and deep sound turned out to be the first 4th order I built for two gray coned, red lettered, inverted dustcap Rockford Fosgate Series 1 ten inch speakers. We put a 0.5 inch red panel in the center to see the subs inside. Snow, Run DMC, Aerosmith and MC Hammer (it was like 1992) destroyed my best friend's room with only a Yamaha 60Watt receiver! We sold it to a guy in HS and installed a stereo around it (red 1987 Nissan 240SX). The other best was a coffin sized 4th order for two Earthquake 15 inch CPDS for his room. Top Gun chimes made the cabinet grade 13ply floors mive through the carpet (his father loved everything quality, smooth, solid, square, and permanent hence sanded void free floor decking. $$$). The third was a somewhat narrow band 4th order for a JBL 1200GTi. Sooo punchy and solid. Flat in car response, buuttt only to like 25Hertz, and only due to loading of smallish liftback car. Darn it. High free air resonant frequencies on those old GTi subs. Hmm. Wonder why? Hahaha! Light stiff cone, and semi compliant suspension. Duh

[@pgmurray76]

In 1994 my best friend and I almost put 6 into a Dodge Ram extended cab, but he bought a 1969 Chevelle with Pontiac 400 block and Muncie 4 speed first. Then a used 1992 Ford Thunderbird Supercoupe SC in black metallic. Then a new 1999 Acura 2.2CL. Then a new Honda S2000 in 2000 and it had the recalled rear lower suspension arm which broke while accelerating from a stop light across a Route 9 south intersection causing him to sideswipe a plastic slatted chainlink fence for a Ford dealer. Honda engineers and two guys from Japan actually came to inspect the untouched car at the dealership. They repaired the car to factory new specs and opened the recall. He bought the 19th S2000 in NJ at the time. We installed systems from 1991 until around 1996. So many Pimp my Ride or Gas Monkey fast installs. 3 days or less. Marathons. We took one week to plan, buy material, buy components, maybe build the enclosure, and plot/plan. Then they dropped off the car after school on Friday. Some dudes were friends and we let them hang out. Others wanted to stay and we wanted them dead! IASCA, Car Stereo Review, Car Audio and Electronics. Phoenix Gold, Orion, Rockford, Clarion, Sony, HiFonics, Polk, MB Quart, Alpine, Boston, Image Dynamics, neon, 1 inch acrylic, JL Audio, Zapco, JBL, Infinity, stealth systems, Earthquake, PPI. Those were the times.

[@charliefrancis6438]

Hey Paul M it’s funny I live in Tuckerton nj , I went to my first show at English town nj in 1995 , with my 6 15 inch Orion’s , that’s when I found out it was doing over 150 dB

[@pgmurray76]

@@charliefrancis6438 Hell yeah! Shame there is no more actual drag racing there...dB Drags...yes, but no twin turbo LSx motors burning up the track. That setup TOTALLY would do 150dB with stout amplification. That was why my best friend and I wanted to jam them into a Ram truck! I've been to almost every inch of NJ, Highpoint, Cape May, Barnegat, Atlantic City, Atlantic Highlands, Trenton, Freehold, Belmar, Seabright, Jackson, New Egypt...I even used to run in the River2Sea relay race across NJ from Milford to Manasquan Inlet. I can keep typing towns in NJ off the top of my head. My best friend's father used to live in Bayville. My first trip ever on the NJ Parkway (1994) with my new license was down to there in my mom's turbo wagon (Chrysler 2.2l Turbo I only). His uncle was in Silverton and I remember walking past the Silverton Yachts building many times. LBI is only across some water from you. (ok, 2 miles of water!)

[@charliefrancis6438]

I wish dB drag was all over the country again, but I need to travel at least 10 hours to get to a decent show now a days, I am in the middle of a new build using 4 orion 154 hcca and two 8000.1 d in a srt8 dodge magnum , hope I will be done by June

[@MacNifty]

Finally someone getting into the aspects of the science. I seen your videos a couple years ago when you were messing with those little drivers and I said this guy is on to it.

[@swat1229]

Liked, subbed, and commenting. This is the coolest thing I've seen since I got into car audio ten years ago.

[@adamcruse7606]

i think i could listen to you explain enclosures all day. lol

[@whyomgwhywtf]

I have watched 3 of your videos... I now have confirmed of how very little i know about this...

[@Machineheadtim]

same but now I'm enticed to learn more

[@travisbonzpiercy2660]

Dude you are a true master of your craft that is amazing the possibilities. The living setup you have is awesome.

[@nickblyth166]

Most unique enclosure I’ve ever used was a small 4th order bandpass with 6inch 40w subwoofer from an old 5.1 home theatre setup. Sounded decent and I found it that it put out loads of bass around 40-50hz.

[@iansmith9574]

Aperiodic chambering looks very interesting. Could you please do a detailed video on this enclosure.

[@CactusJack252]

I have said countless times. It is often not the amp and sub you have. It’s often the box that you have it in. I’ll never forget I had a friend that had one 10 hooked up to a 500 watt amp and a custom box. He took it out and put in two 12’s and a 1000 watt amp. He used a standard ported box. 24 hours later he was putting the 10 inch sub back in. It played louder and clearer than the 12’s.

[@metalrott324]

I've built a great sounding 8th order using a 10" sub and 10" passive radiator. The radiator stopped the primary chamber from phase cancellation in the higher toned chambers. I sold that box years ago, I'm building a new one with 18" innards for a sick theater setup.

[@situationunchanged9733]

Damn. You really know you're stuff! And very informative, I've learned a shit load in just a few minutes! I had no idea there was so much variety in enclosures and they could be so complicated. Big respect 👍

[@nameboy3486]

i wanna learn how to build these really insane enclosures it's fun when one smaller sub is able to blow minds

[@GamersTrashTalk]

same, wheres the math behind it! WE DEMAND MATH!!!

[@Xenro66]

I heavily agree. I'd absolutely love to get into designing and modelling these insane enclosures.

[@PrinceWesterburg]

Scaling any of these designs up for the 15" drivers I have would mean a bigger house! LOL Great channel - instant sub!

[@chrislacombe9532]

I've been pleased with vented clamshell designs the last couple years. Easy to build overall and cover a good range while muting some low emd mechanical artifacts. Good to see your videos Pete!

[@porkchopspapi5757]

Can you give an example to look at?

[@ResurrectionUph]

Great video. This is the 3rd time ive watched it. Following you on Instagram now. I'm a professional interior shop for hotrods, muscle cars ect.. Car stereo got me into doing interior. Now I still get to do car stereo on most of my custom builds..

[@PortaPA]

Hat off to you. As a mechanical engineer and audio hobbyist, I can tell you are a true professional. I now want to study these more exotic enclosures and try some out. Would you have a recommendation on what type(s) give the best combination of small size, high output, over an average frequency range (20-70hz) for a given driver and input power?

[@earthling2022]

Thanks for this video....thinking of making a 6th order rear loaded horn (no.3) or 6th order bass reflex (no.4) for a JL 13w7.... approx 1m x 0.36m x 0.44m size. wanted some decent lows without too many spikes (20hz to 40hz ?)....never knew the enclosures could make so much difference !

[@HellToro99]

The TLine is my fav. I love when you setup a small driver that can perform low end smoothly with authority!

[@PigsOnTheWings1]

I've never felt so stupid. I love it. Keep it comin'

[@WS1_AUTOS_N_STUFF]

PigsOnTheWings I’m not alone 😆 I was thinking the same thing 😆 I am familiar with a good number of orders but he definitely widened the horizon 👍

[@azeemtics6613]

He can’t count

[@kyleedooley7970]

The most impressive enclosures I've ever seen are the ones in this video. No shit bro.

[@tehKJM]

Honestly this is the best info about enclosures out there. Now realized, the box I use for my car is not actually a “6th order” parallel, but in fact looking more like a 5th order parallel tuned bandpass? since it’s a ported box tuned to 28.5hz with a removable resonant chamber (the “Port” is the same height and width as the chamber itself) on top that adds a wicked peak at 60-80hz.

[@scottwheeler2494]

My favorite woofer install/design was years ago (the ‘80s ) but still remain number one in my heart. Buddy cut a hole in the living room floor of his trailer for a 24” Hartley woofer. Old school. Drove it with a Southwest 100 watt tube amp. He altered the size and dampening of a box built around the woofer to tune his room output. He was classical organ music freak so this puppy was perfect for him. Remember this was before subs were really high output. He blew out his kitchen window of his trailer. The bass cuts on some of his records could cause the needle to jump out of the groove. I worked as local crew for U2 that year and even sub stack with more than 50k of Crown amps were not any louder or deeper than Tony’s trailer. 2nd favorite install is the recording room for the main studio at XM satellite radio in Washington. It is a multimillion dollar studio and at the time when XM was new, it was state of the art. (No idea what it is now, it’s been years since I was last there). It was a 20-20 room at pretty absurd levels. Best of all it sounded like the folks performing in the other room. The best A to B test you can do. Live Los Lobos vs. recorded Los Lobos. Live Dave Alvin vs. recorded Dave Alvin. You get the picture. Amazing room. Amazing recordings later butchered on XM Radio’s signal chain.

[@DescartesRenegade]

you production quality is shockingly good for 126k subscribers.

[@smigletat9634]

So you are telling me in 7 mo he has QUADRUPLED his subs. 😮 Holy Cow!! Truly the most underrated man on KZbin currently! I have known of Pete since 2005… A man of acoustic wisdom wouldn’t even scratch the surface…

[@samuellbrowning]

I’ve always wondered how passive radiators change response and could be it’s own category

[@smokinjoe6256]

Wow, thank you for sharing. Next level info.

[@drrckhamilton]

I think it's cool when this happens because it adds to the vlogs. Thanks.

[@WS1_AUTOS_N_STUFF]

I subscribed first because of your accent but mainly because you have a lot of knowledge! 👍 I run single sub for comp and get trophies 🏆 because of chambers and not conventional box with 20 subs! I’m mainly a port guy but sealed has its place, decent range of tones. Excellent channel 👍👍👍

[@ronbatchelor2213]

Can you post a video of your subwoofer setup. Along with the specs too? I'm trying to get a better setup then what I have currently without having multiple subwoofers

[@WS1_AUTOS_N_STUFF]

Ron, I’ll try , I’m having issues with my videos uploading! Look up obcon boxes they make chambered . They’re not bad,

[@WS1_AUTOS_N_STUFF]

It’s the obcon GZ series box with 2 circular ports ! It’s what I used to use, it sounds good 👌🏻 I ran my kove sub in it years ago but I have hcca now ! Kove is really good stuff too

[@0525ohhwell]

"The dayton classics towers in my living room playing down to around 10 hz".... Hold up.. WHAT???

[@not-stock]

In 1979 I worked for Transportation Electronics of Hopkins MN, doing sound systems, alarms, etc, in new automobiles mostly direct from dealers. Our specialty was "woodies" which involved backing up large interior panels with 1/2 plywood for speaker mounting. We had a large selection of hard-won paper patterns to choose from. With the right heads these systems were very impressive for completely hidden speakers. Of course, after that things got ridiculous with huge visible drivers, etc. In about 1990, a co-worker and I, using our employer's hemi-anechoic chamber and B&K analysis system to design, then optimize after I built it, a giant ported enclosure of 1 inch presswood with 12 inch driver, 4 inch diameter pvc port. It showed it could produce effortless and flat output within 1 db to 13 Hz. Of course it was large, using most of a 4x8 foot sheet of presswood. Anyway, I just found your channel and it's been a lot of fun watching, remembering the golden age of audio I survived, and learning from you. Thank you sir. Wish I was your neighbor, bet we'd get into some projects together!

[@john90430]

I grew up with an Altec Lansing 604C in a Karlson enclosure that my dad assembled from a kit. Warm and rich sounding when driven by a Williamson type tube amplifier.

[@bedsbay1]

Can you do a video on the dayton classic towers you mention in this video?

[@hashtaglobotomy2655]

You are seriously awesome man. I love this kind of stuff. Really like the dual 10 4th and 6th design you had going.. Now if you did 2 of those and sent the waves to a central chamber what would that even be?

[@supersteveenglish7340]

A quasi-6th and 8th order. Which is what the 4th/6th enclosure is in the trunk of a car with the seat down or a ported rear deck

[@jus1taj]

Just subscribed. I like this level of conversation about bass. I’m new at this but eager to learn more. Beyond the hype. Good stuff.

[@jonanderson4474]

Check out the gately audio channel once and this showed up. Glad I did. Thanks for the video. I normally wait a few videos to subscribe. Not after this presentation. Subscriber now. Will peruse your other videos in thw morning. Amazed by so much knowledge in just over five minutes.

[@StockiGTI]

Mind Blown

[@myfagan]

For me... actual transmission line enclosures are the best. I cant really describe it but its different. I like super clean bass that can go really low

[@jonathansturm4163]

I've loved TLs since the 1970s for the reason you state. My current mains are VAF DC-Xs, but I recently came across this: kzbin.info/www/bejne/e3bLYWSGjZKkb6s These are DIY Voigt enclosures, a hybrid TL and back-loaded horn. I'm too old and arthritic to do much DIY these days, but I have a very good friend I will have no trouble persuading to help out. All I really have to do is live long enough to hear the finished product :-)

[@CursedCow678]

Holly damn. I found your channel again. Yes I am subscribed but I have not seen anything in so long. Good to see ya again!!!

[@anthonysilva5015]

This was such an amazing educational video!! I know very little about box design but have been watching a few videos here and there and this video REALLY peaked my interest! I have a 1995 Buick RMW (Road Master Wagon) and I want to put some bass in it and was wanting a couple 8's in the area where the third row feet go and still have room for a little dip for short legs/my kids legs. With what you have here I feel like I could produce the same sound from a smaller speaker... amazing engineering work!!

[@ericw4237]

Do you have a video of your home speakers with the Dayton audio's? ( The ones that play to 10 htz!) I've been wanting to build a set of home towers for a while now. I'd be interested in seeing that build.

[@6spdkeg]

Where do I find the details of your Dayton Audio Classic towers?

[@fabipfr]

Yea +1 here

[@CG-sv2nw]

Ok so this video has helped me move forward on my design for a sub box holding 12 12" drivers in a single box. A Hybrid box would be ideal. I was waiting for that type since minute 2 of the video! 👌👍👍👍👍

[@davidpost6164]

I took apart a small bose subwoofer and really liked the design and i seen similar on here but i looked the nose design better. I liked the way that Bose combines both sides pressureto get rid of the heavy air pressure that would normally come out on the port.

[@tayley284]

Thorough and strait to the point . No bullshit shoved in between... Very nice content my friend...

[@jasper20017]

Any chance you could go into greater detail about the Home Theater speakers you were talking about with the Dayton classics? I have 1 Dayton classic 8 with 2 8" Dayton passive radiators and I have happy with the output but. 10 Hz though? Thats phenominal. Deserves it's own video. Also excellent videos, keep up the amazing content

[@kencohagen4967]

Hey Sophie! Eons ago when I was just getting into Audio a friend of mine from High School became an engineer for the Palo Verde Nuke plant west of Phoenix. He built a labyrinth partition with an 18" driver from what became Parts Express. I still remember the adds for those massive woofers, at least they were massive for their time. He had a pair of magneplanars on either side of this sub and they were powered by a single Carver Cube, with the sub being powered by a separate Cube. 250 watts per side and 500 watts for the sub. He worked on the sub for a very long time, testing it here and there until he got it tuned just the way he wanted it which coincided with his parents trip to Las Vegas. So he did what any audiophile would do and brought everything out into the living room for a sound test. The result was a picture window exiting the front of the house, and while he was at work I was appointed to watch the house until the glass company came and replaced the front window. After that we brought everything back into his bedroom and fire it up in there, and the bass was incredible. Without any equipment to measure its response we had to guess at what it was by doing the math, but it was supposed to reach down to 20 Hz or so. My guess is he made it very close to the designed parameters.

[@trecedaves3159]

8th order sri box! Best sounding sub encloser for a single small driver I've heard to date.

[@thehayze]

now this is the guy you have set your system up and then never touch it. he does know best.

[@waugy370z8]

And yet someone will think they can get just a little better sound and have to f@ck it all up 😆. Then come back and say "dude i dont know what happened but it sounds like shit" 😆

[@ATCA]

So how can I get you or someone similar to design me an enclosure for my home theatre, under floor enclosure?

[@pgmurray76]

My God! SUBSCRIBED! I am so happy to have stumbled upon your channel! You are obviously a top Engineer, Audio Engineer, and gifted artist. You explained each type perfectly with articulate reasons for impedance, bandwidth, and loading manipulation for each type. When I get my finances straight I will try my hardest to choose and make one or two of these designs. I will most likely have to build something already designed and thought out using a specific transducer, but it will still be VERY satisfying. Thank you Sir!

[@haisano]

So yeah, that was fascinating. Thanks for posting!

[@armandocamorra2488]

I want to see more detail from your home cinema loudspeakers

[@B4EVR]

Old school here with my Rockford Fosgate 650 Mosfet using a 7th order box with two 12" Fosgate Punch Pro series SPP-128 subwoofers. Is there a better design I should be using with these two twelves?

[@johnsmith-oy9kx]

An expert, but simple... rare combination of a genius

[@houseoffire72]

Excellent and well delivered content. Had to sub. Ive recently after 20+ yr away from audio decided to finally build my myself a small budget home stereo set up... I built MTM's using two 6.5s & silk dome tweeters. My subs are Dayton 8" classics. I'm very curious on your Dayton set up. I'm glad I found your channel.

Very interesting ! How do you simulate these mixed types - with which programm ?

[@Curi0u50ne]

Getting speaker geometry juss right is like when full suspension bike manufacturers all tried to justify their rear suspension spring set up!😂

Hi PK....I've been a fan since you were in Arizona? You made a box for I think 2 8's in your little wooden shed for a guy in a pickup. I enjoy all your videos, excellent work. You are extremely knowledgable in audio accoustics. Glad to see you are back- Keep keeping up the good work!

[@allanbanks4062]

Also-Pete, I may not always know what you are talking about with DACs, converters, etc- but your presentation is always spot on. BTW- Are those Crown amplifiers? :)

[@anthonysandoval965]

Dude your my idole and inspire me first off. On your 6th order variant when wiring it is it best in parallel or series. I do appreciate your video's, knowledge and inspiration!

[@mdjamesd]

Could you do a video on the Dayton Classic towers you made?

[@kylewills74]

Well I came here because I was looking to make a ported horn (horn on the front and port off the back as you can simulate on Hornresp). After learning of the 5th order horn, I have to say this seems like an attractive opinion/alternative. Could anyone point me in the direction of more information which compares and contrasts these two designs?? I am really curious about the benefits of porting into the throat and I can't find much information myself.

It's good to have an episode on enclosures that are less well known but I still do not see episodes on some common or not so very common enclosure types that cover a significant part of designs out there. I'm referring of course to transmission lines, (quarter-wave) resonance and, most of all, open baffle.

[@ExStaticBass]

The best I've built or heard was a dual tuned T-line in that both faces of the driver fire into an infinite baffled enclosure and the timing mismatch caused a far more level output. It was tuned to 30hz and 90hz if i remember correctly. I also kerfed the port end to make it more of a horn guide. It was finished with poly glass epoxy and fiberglass and used a Dayton Audio pro audio 12" driver. It's been known to separate the seams of pant legs without tearing any of the fabric.

Would love to see the design and measurement of those Dayton towers!

[@vincentkoster6291]

Me too! I never knew that design and I'm really interested in the concept of a tower speaker playing down to 20Hz

[@MrAtrandom]

Yeah I have two silverflute 8s in tapered transmission line towers that play flat down to 30hz and sound great doing so. But below 20hz on some Dayton mids seems a touch hard to believe. I did do a transmission line for two of the designer series 5.25s and they played down to about 27hz after room gain but the drop off was drastic below that.

[@PetreAdrian]

can you do a small test with the passive radiators - are they actually good or not.. jbl is using them a lot in all of their bluetooth speakers - small and now even quite large ones.

[@jjhack3r]

Passive radiators are great. If it’s diy, the tuning will make or break the performance and quality.

One of the more interesting enclosures that I've came across in consumer electronics is a 4th order bandpass "3D ASW" (acoustic super woofer) in a Hitachi CX-W750/TRK-D90/TRK-3D95. It has a 4" driver that originally has no vent on the pole piece. I bought one years ago in a pretty beat up condition. The bass was deep but quickly deteriorated with more volume. I had the idea of drilling a hole to the pole piece and executed it. Oh how fun times cleaning out the air gap as I originally didn't remove the dust cap to prevent metal from ending up where they shouldn't. Then I added some padding to the enclosure and put it back together. The difference was immense (for the power output!), now the bass would play much louder and the limits of the system would be met or exceeded much more smoothly. The interesting part of the enclosure is that all pointed towards it originally being a 6th order design.

I once designed this box, it’s was roughly 6 cubic feet, it housed a single Jensen xs 10, behind the baffle cutout was was a 11” baffle rings that extended till about 3” from the rear wall, larger section used an 8” pvc pipe roughly 5” in length, it seen maybe 100 watts at most and was loud enough to flex the walls in my house

[@squaty1212]

Where can I find the build plans and parts list for the Dayton Classic Towers you mentioned for home theater?

[@jevchance]

Also interested in learning more about these.

[@mareli82]

il tack on this as well sounds interesting

[@supersteveenglish7340]

Sneak in his house and measure them with a hand-held xray machine
