This background music makes me feel like I wanna go do a shit ton of mushrooms then go watch Circus Olay in Vegas, Lol. Killer beat though. Such a great showcase of the detail that people put into their box designs. Awesome video dude!

[@Mkvy]

Robb A yeah I could have put a more mainstream track on it, but it goes well with the task of drilling etc!

[@Mkvy]

This enclosure drives wildlife crazy. Ive never seen so many animals running for their lives like the parting of the 7 seas. Birds, deer, squirrels, rabbits etc. you literally see the road ahead clearing on country lanes, unbelievable power of the u series in a well designed box

[@Mkvy]

Just to advise , I used titebond 3 for all panels and just a bead of hard setting gripfill adhesive on the inner edges. I don’t normally. But the cuts were not perfect. It’s my enclosure and my work so I don’t need to be told it’s not precessional. I know it’s not recommended to use any filler inside the box. Fortunately it’s a free country compared to many in the world

[@UniCrafter]

very nice box, rare to see a 6th order bass reflex, would've been cool to see acrylic side panel even, nice job on the construction

[@sethh8892]

If you think 6th order bandpass enclosures are rare then you havent been looking. It's only rare to find 6th order bandpass enclosure is that are in series. It's also not necessary to say bass reflex after saying 6 order. It's kind of redundant being as though 2 bass reflex enclosures are used to make a 6th order.

[@UniCrafter]

@@sethh8892 there are 2 types of 6th orders, 6th order bandpasses (very common in car audio), and 6th order bass reflex, of which this is one of about 3 total I've ever seen. I've seen maybe 100 6th order bandpasses, and have built 2 myself. By saying bass reflex I mean its like a ported box with another chamber on the back of the drier, instead of a standard 6th order which would have another chamber on the front of the driver.

[@bjones8458]

Series tuned 6th order. Just rare because it's harder to tune properly.. idk why ppl are just saying bass reflex and bandpass box.. this is a series tuned 6th order. The more common being parallel tuned 6th order which is easier to build because your essentially just putting a a sub between 2 ported boxes vs alot more calculation with a series tuned 6th. Both are bandpass boxes..

[@phrosda]

Killer build!

[@brycelawmaster3746]

am I missing something here? where do the subs mount, didn't see any cut outs?

[@Mkvy]

Bryce Lawmaster the cutouts are on the same side as the central vent , each sub is mounted either side of the vent

[@greglatta2602]

@@Mkvy what are you talking about the first ten seconds the box has no speaker mounting location

[@Mkvy]

It’s amazing, do you know that wood glue seeps into the porous mdf and sets giving it strength more than any screw can give?

[@Mkvy]

All negative comments will be deleted I am not interested in negative hatred. There are enough bad things. You are kindly requested to leave via the exit. This is just a speaker box. Not worth complaining in the comments, I will delete.

[@onewheelup]

one heavy ass box.

Which Speaker is better: 1.- The "Front sound" without obstacles and the "Back sound" runs through a maze to reach the Speaker's exit. 2.- The "Front sound" runs through a maze to reach the Speaker's exit, and the "Back sound" comes out through a "simple tube" thanks

thats some great woodwork. would love to hear something like this at the uk meets

I’m so fuckin impressed man. I live in Cali, do you make enclosures for sale by chance? I’d pay around $2,500 for something of this quality.

[@metalmulishaz123]

Where do you get the enclosure design at? The link that you used is not working.

[@Mkvy]

Maybe have a look in AD designs website

[@mrt528]

Wait, all that great woodwork and close it all up with drywall screws, nice 👍 lol

[@Mkvy]

all screws are removed after the glue sets. When he glue sets the screws have no use. They can be used on the next build. Wood glue is stronger than the wood. The first thing to fail is the wood. Not the glued joins

[@shean-koklim4197]

Whats the dimension of the box? My RF Punch would sound great in it I think.

[@Mkvy]

Better going to AD designs enclosure design service like I did and get a design specific to your cabin geometry and other specs

[@donnyyayo2294]

Whats the purpose of designing a box ? Is it the more difficult to build the better ?

[@Mkvy]

No matter how difficult or how easy it is to build the end result is the goal

[@daneprostamo-brown6552]

Donny Yayo this enclosure is designed by an acoustic engineer for optimum frequency response and efficiency for the given drivers and desired system goal

[@donnyyayo2294]

Thanks guys was just wondering if the box had alot of obstacles inside than the sound and feel of the bass is better

[@carlosmauricioespitia6016]

I had to completely lower volume on my phone as it began

[@Mkvy]

I know but that’s the joy of noise that’s got no commercial copyright. Teams of copyright music match are scouring everyone’s videos to take their revenue away just because a video may have a short background section of their music. Most of videos will be either muted or have background noise from now on

[@daytrace4635]

why would you use the u's for sq? x wouldve been the better driver for that imo but these us slam going to post a couple videos of mine hopefully soon

[@Mkvy]

Random Roger because the x series were not in stock in the uk at that time, and the u series were on offer and in stock

[@daytrace4635]

@@Mkvy ok that makes more sense, ever thought about investing in fi? very good quality subs I have a 2018 civic with 2 u 12s but before that I had a sp4+ 15 in a pretty big box and it was super good, going to put a bigger port in it and meter it as I will put my u12s in a crx within the year probably, hoping to hit 160 in crx but we'll see haha likely doing 148ish in the civic, fi has a q series which is very good sq used to have them awhile ago, very clean bass, I would venture to say fi is best quality(longest wait time) then probably dd and sundown but just my opinions with the many subs Ive had lol

[@Mkvy]

The u12s are seriously heavy subs, my suspension drops each time i drop one of them in the box. The box and subs are impossible for one person to pick up, so install in the trunk and tilt the box in. Im not a numbers person SPL. Just i like music, have fun with your projects

[@Mkvy]

The u series are a more SQ orientated sub compared to the x series. Just look at the response in a 4th order 2.5 cu ft box. The u series has no dip in the upper bass notes . The x series has more of a peak in low end. Therefore the u series is easier to design an SQ alignment

[@daytrace4635]

@@Mkvy sq is more of a low extension rather than upper, yes xs tend to hiccup on higher notes and have a lower fs but u's dont have the same motor force and have way higher fs granted you could build a naturally flat box and I would think u would sound better untill you get to about 25 hz and below which is really just the bottom of the bass shelf anyways before its just moving air and not really audible, seems like u's are versatile in their tuning, so in a way I agree with you

[@madscientist6869]

D.R. Dickey I don’t think subs can have big sound systems due to pressurisation under water. Not to mention the flex on the periscope

[@justingillette8287]

the use of complex subwoofer enclosure topology is negated by todays modern DSP technology. you could easily do a single 18" driver on same power same enclosure size simpler box design and a little eq function from a (plug and play) dsp unit, save money and pain and get same acoustical results. I like Pete at Audio Dynamics, he is a genius for sure, but I am not convinced his complex enclosure designs are that beneficial these days. you need dsp to time delay the mids and highs to compensate for the group delay introduced by the complex enclosure design anyway.

[@Mkvy]

if only i could fit an 18 into my trunk

[@Mkvy]

The more plugins in the chain needed to improve sound the worse the sound. The founder of pro audio speaker maker Funktion one has lots of lectures about this

[@justingillette8287]

The foot print of that box you built would allow an 18” driver you only need like 8 cubes for many great 18” driver units. True cascading filters in the signal chain is not a good idea you are correct and function one knows their stuff, but that sub enclosure is doing the same thing only it’s a passive filter as supposed to active you can fine tune

[@Mkvy]

Justin Gillette unfortunately the net volume of the box is 4.88 cu ft. That’s the max limit. I was thinking of a single zv5 15 in a future build though . The only way would be sub facing up , port facing rear , a wide letterbox about 2x36 inches wide with the amp located above the slot port. That way the cables can be clear of the port

[@justingillette8287]

Well honestly I don't know the dimensions of the box. I apologize for assuming the box size. When you say net volume of the box what is the gross volume if you dropped an 18" sub in a box built to the external dimensions available with a simple slot port you would gain a lot of internal volume. I think you are on the right track keep up the good work!!!

[@doggiefresh241]

@@Mkvy its better watching it silent. And where is the subs.

[@Mkvy]

Hilos K Jackson 80% of viewers have liked this video, so I’m very happy with the amazing music and no subtitles needed as it’s a timelapse. Although I could have added speeded up voice by 300% to match the beats

[@Mkvy]

Hilos K Jackson also it’s a good idea to use an audio listening method that can give 20 htz - 20khz. I.e not a smart phone speaker

[@utubecomment21]

Can't believe you've got a box from Pete aka Hexibase aka PWK, and you're using caulk like a bunch of amateurs. Shocking! From the man himself "Notice that I don't use silicone on the inside of my enclosures"- 2:45 - kzbin.info/www/bejne/jqrRoo2BbLVlpM0

[@Mkvy]

Yeah you are right! The shop cut some panels at a slight angle. But I decided to use gripfill to fill the error. Not to worry the sound is amazing . Normally I run just a bead of wood glue

[@Mkvy]

Basically the final top panel was installed and upon internal inspection with a GoPro I noticed the slight gaps caused by an angled cut on the internal wave guides. I filled them in with a super hard non alcohol based grip fill. I decided to run a small line of gripfill in all seems even though they did not need it. Just to be double sure. And wiped all excess filler with a wet cloth. After testing with a Dayton tone sweep the result was as predicted by Pete

[@VaracolacidVesci]

Mdf its tooo heavy and has lower properties than plywood. Why use mdf? And you use tooo many screws. You dont need clamps anymore

[@Mkvy]

I used mdf because it’s readily available where I live, but agreed it would be lighter and maybe sound different but harder to work with

[@Mkvy]

Every screw was 4 inch spacing. I clamped the corners just to make sure they would set the corners good.

[@andrekershaw3903]

The birch board does sound better but it's double the price of MDF and nearly as heavy.
