[@zeone311]

Like your video. Great job. I think if you care about accuracy, two sealed subs are the way to go.

[@linkingaj]

What do you think about the Yamaha NSSW300 Subwoofer? if possible can you test it out?

[@thiagodelgado3128]

What do you think about SB3000? even be sealed seams be far better than Klipsch R115SW. I think about price point.

[@teewhyTHA]

Channa! Can you make a video about what movies/scenes/songs you like to test speakers with? I have heard you mention "A Quiet Place," and the Red Circle scene from "John Wick 1". We trust your advice. Maybe a top 5 songs/Top 5 scenes, and then mention what you are listening for for each one?

[@festushaggen2563]

Having owned both sealed and ported, I believe the sealed for music and ported for movies expression is pretty accurate. The ported will give you that much more for your explosions and action movie moments. The sealed sounds so much tighter for music and less explosive for movies. They both work either way but each does seem to do one thing a little better. That's how I'd go, depending on what I want a sub for. I think duals can be mixed though. I have that now and it gives the best of both worlds.

[@maincharacter2677]

However larger sealed boxes can hit hard in low frequencies and are extremely good in films, I know this because I've built different sealed enclosures large and small.

[@Audioholics]

Ported subs being "slow" is a myth. AS long as the sub is tuned properly and has low group delay, it will not be any less accurate than a sealed sub. The "slow" sound is usually a problem with controlling room modes or getting a badly designed ported sub more than a problem with ported designs in general. see: www.audioholics.com/loudspeaker-design/sealed-vs-ported-subwoofers

[@randall96]

Would you say that at lower budgets, it is in fact the case that sealed subs are "faster"? Again there may be exceptions, but is it a "more common" situation?

[@xanderguldie]

Physics-wise that doesn't make sense as the woofer should react faster due to the pressure of the box. Also the best responding subwoofers are servo controlled.

[@sirjonsmithiii992]

Love my sealed SVS sub.I use it in my living room for tv/movies. The tightness is jaw dropping. And my wifey seems to complain less about it (maybe). ;)

[@TechnoDad]

LOL, awesome!

[@Rajantuber]

I feel a musical sub is the way to go...even for movies....I mean most of the contents in a movie are based on music background...the thuds and the booms are rare.

[@TechnoDad]

This is true. Most movies, except super hero movies, will have more music as opposed to explosions.

[@raphaelmeillat8527]

Yet, the most spectacular moments that are going to make a difference between a good and a great experience are exactly the visceral moments you're talking about. Think dinosaur steps in Jurassic Park, etc. Not sure you can actually tell the difference in terms of musicality between a good sealed sub and a good ported one. Just my 2 cents !

[@bigben9056]

musical sub lol.peoploe just dont get why ported sund different.its about the room gain-ported have better response untill tuned feq so they get more fro the room and start to sound boomy and all that shit.you just need to tune it

[@gaminginframes2819]

I had 4 - 12" (sealed) 1000 watt rms subs in my 4Runner back in the mid 2000's, and I had the amps and capacitors to push them. I was able to achieve insane amounts of hair raising rumble while still keeping clean, tight bass. The problem with pushing that much sealed power (at higher volumes) inside a car is that I thought my eardrums were literally going to burst. I've sat inside some ported demo cars and found it much easier on my eardrums while still being able to feel it raise my hair. As for my home, I'm in a guest house so I'm still content with my older 10" ported Velodyne sub.

[@garykarczewski6678]

I chose a pair of SVS SB4000 mainly because I feel sealed subs are a tighter sounding for music, plus the size is smaller which is a plus for my home. No regrets having sealed subs. Love your videos by the way TD!

[@TechnoDad]

Hi Gary! Sounds like you got some good bass with two SB4000s!! I think this PB4000 is a little too big for my living room but it sounds amazing! Thank you for watching Gary!

[@cmdoggy24]

Techno Dad My dedicated theater is 20x18x10. I have never heard an SVS sub in person. Assuming cost isn’t an issue and going with dual ported, what size would you recommend without it being ridiculous overkill? I’ve been reading good things about the new PB3000’s but I am willing to go bigger if there’s an appreciable difference on an upgrade.

[@TechnoDad]

Hi Chris, great question! I would go with as much as you can afford. Dual SB16s might be a good fit for your room since it's 3500 cubic feet. Here's what mike said above, "I’ve owned dual ported subs for 20 years. Until now. I now have dual SB16 Ultra’s and they sound a perform better than any of my previous ported subs. Property calibrated with my Denon X8500H I’m finding that I’m now listening to more music again, as before I never listened to music in our dedicated home theatre. I’m still easily able to reach sub 20hz with my SB16’s and that’s just fine for me. I’ve never heard a sealed sub that can achieve the same SPL’s for movies in particular that what my SB16’s can. Because of this, I am also now able to put them in their best listening positions unlike before with my previous ported subs due to their footprint, and not taking up as much precious real estate within my home theatre. The SVS SB16 ULTRA’S are a win win for my personal use!" Hope that helps!

[@beornthebear.8220]

I've built several speaker cabinets, including a 2x15 front-facing rear-loaded folded horn for my old bass amp, sealed and bass reflex cabs with 15s and 12s for stereo. The 15s in mynas setup had 18 lb magnet structures, and could get very loud without much wattage, I always thought that a small, sealed enclosure (not true infinite baffle) would have a smooth roll-off as the bass put more pressure on the air in the cabinet, and that a port would get deeper, but have a sudden drop if the bass was too deep. I thought the transient response was more related to the power of the magnet and size of the voice coil along with proper port design, however, I can't argue with a spec sheet on a sealed subwoofer that goes down to 20 Hz +- 3 dB. I play and listen to music with a 5-string bass with a low B, which I guess is about 31 Hz. I can't hear below about 28 Hz (I tested it with a program and headphones that go from 5 - 35k +- 3dB. I'm not young, and considering I've played and listened to very loud music, my hearing tops off at about 15k, though less compression in the music tends to add spatial dimension to the sound to my ear. I listen mainly to hard rock and metal.I would like to check out some of my music with sealed and ported subs to see if I can hear the difference. I don't play video games or listen to movies loud.I'm thinking of getting pair of SVS 1000s. The sealed ones could keep my 12" 3-way systems sitting on them while keeping the tweeters aligned with my ears, while the ported ones would rain them a bit high. I suppose I could put them on the inside of my current speakers. BTW, good video.

[@gregrichard9192]

Great video. I do approximately 60 % tv/ movies and 40% music. Somehow i prefer a ported sub over a sealed sub .

[@TechnoDad]

Hi Greg! Thanks for sharing!

Iam using SB4000 and it sound Amazing...I recently watched A Quiet place and ohh god it has great power on low end. .thanks for the lovely video 😍

[@TechnoDad]

Oh yeah, that movie is just nuts with LFE!

[@senseisprotege3632]

I'd always had ported dual subs in my car, so I went ported for home as well and have not been disappointed. Also consider upgrading the linking cable. The one provided from Yamaha was definitely so-so. The new cable made the sub sound reborn. Great video 🔥

[@tobyhines7587]

Used a 15" sealed sub for 20+ years with a 100 watt Nikko power amp. After running bass sweeps I found it had No audible output below 40Hz. The amps meters showed output just no sound. Dual PB-1000s now and output below 40Hz and I'm loving it. Music and Movies.

[@TechnoDad]

Nice Toby!!

[@lakorai2]

Large 12" sealed sub than gets down to 20hz with 500 to 1000 watts. Plenty loud, plenty accurate and you only need 1cuft of airspace usually. I use the Image Dynamics IDQ12 with a bash 500w plate amplifier. Plenty loud and gets low.

[@drummerkev1627]

[@TechnoDad]

Hi Mike! Thank you for watching and sharing your experience! I'm sure dual SB16s move a TON of air!

[@Lafiro]

I am in the process of redoing/finishing my basement. I ran cables specifically for a 7.2.4 setup. However my downfalls are a short ceiling height (under 8 feet) and that one side has the staircase and is open on both sides to the rest of the basement. I am not just there yet to buy, but the SVS 16 Ultra's caught my eye. I just wish I could find a place to listen to these much higher end subs before just randomly buying them when I am ready. Not only do I need to finish the floor and paint, but I need HDMI 2.1 and eARC to come out before I can even buy a TV.

[@drummerkev1627]

lafiro86 If go to svsound.com you can look under authorized dealers closest to you. I’d call first just to make sure they have display models of the ultra 16’s. Hope this helps.

[@bassproable]

As a musician (bass) and an avid music and HT enthusiasts ive had both sealed and ported cabinets and subs. It really depends on the room, placement and how much power you are running.

[@eja35oz]

I just got the sb 3000 from svs and that goes down to 17hz. It Also has an app. For $1000 I feel like that's an incredible sub. It's about 15x15x15. Perfect size for the wife acceptance factor 😊

[@TechnoDad]

Nice! I saw one at CES and it is quite small. Thanks for sharing!

[@voodoo9077]

Nice! I was checking out that sub. How do you like it for movies? What sub did you have before?

[@eja35oz]

@@voodoo9077 I had a def tech pro 800 sub. Decent sub....The SB 3000 is on a whole other level. I have never experienced bass like that before. It's absolutely incredible for movies. Very clean bass that can go so low in frequency that you may not hear it but you feel it in your chest. It performs so well that it is very comparable to their award winning 4000 series but for a lot less money. The sb3000 is a very impressive sub and definitely worth checking out. When SVS asked for feedback on it people responded with worry that it was so good it would negatively effect their 4000 series sales. But SVS has come out and said that if it means more people can experience their subs because it is more affordable then they're ok with the loss in 4000 sales.

[@bakoe7604]

You should get 2 Of em if you want even smoother and cleaner bass 🤙🤙.

[@ryanherrera9171]

I own one as well, I dig mine.

[@I_AM_HUGO]

My room is a little big at just about 4560 cubic ft. The room is very quiet, and tight, and does not have any echo. My SB1000 sounds good, but I know I’m not getting what I should for a room that size. I’m thinking of buying another one, but was wondering if I should buy the PB 1000 to go with it instead. I don’t know if I should go bigger on the second one because I don’t want to drown out the SB. Any thoughts?

[@mthemaniac]

My opinion... order of best sound quality: Open baffle, infinite baffle, sealed box, ported box.

[@TechnoDad]

Nice

[@TaylorMadeTheater]

Well put bro! I would add that sealed subs are strongest in the low teen hz as they have a more flat response that doesn't taper as much on the graphs but can never be felt as loud as a ported sub with the same wattage, as you said. Also the svs ported subs are tuned to boost that sweet 17-22 hz area that is most common in movies or rap, which is where it really counts for me! The SVS ported subs are also very tight due to the large driver simulating the resistance the woofer would have with a sealed box. The SVS 3000 series is a new breakthrough in that technology. Yay!

[@TechnoDad]

Thanks for watching Taylor! And yeah, that SB3000 is small and powerful. I’m excited to check it out for you guys!

[@voodoo9077]

May just have to trade in my PB2000. Though it goes down to 17hz it's a massive size sub and no way down the road i can get 2 PB2000 to fit nicely in my room. SB3000 it is!

[@TaylorMadeTheater]

​@@TechnoDad I do want to see more on the SB-3000 vs the PB-3000 in sealed mode then ported mode.

[@TechnoDad]

Tha_Vilaman has both, ask him if he can make a video about it: kzbin.info/www/bejne/naakeKGHoqt3fqs

[@bernarddussault2365]

very good info ! thank you . so closed is best for me

[@6spdkeg]

For mostly movies. How about mixing sub brand and boxes? Like a sealed 12" SVS SB-1000 front of room, 12" ported diagonal across the room( Bic Acoustech PL-200 II)

[@jaekamacho1416]

Yea i kinda do believe in that "sb for music, pb for movies" thing. For the last ten yrs when i first got into H.T. Ive always had a klipsch brand set up with two 200wrms 10 ported subs sw450 i believe they are called and they never disappointed in any way, movies and music both sounded great. Up until this past yr when i finally decided to upgrade i first went with a pair of svs sb 12nsd's, and good thing for that 45 day trial cause no matter what i did in adjustments, they never sounded anywhere as good as my older "weaker" subs. Svs at 400wrms vs sw450 at 200wrms. I returned them before the trial was up and luckily for me the thx monolith's by monoprice went on sale and actually for about $100 less i was able to get dual 500wrms ported subs, and these boys are tanks! U can convert them to "sealed" with plugs and a quick tuning, but to me ported sounds awesome for both movies and music. I like the older rap music and it doesn't have that electronic bass like today's does. I also listen to rock,metal etc... I rediscovered NIN on a whole nother level thanks to these subs! I say get a ported sub that also has a sealed tuning feature. Or get a one of those subs that have a passive radiator, about the same size as a sealed but sound deeper thanks to the radiator. They are pricier though!

[@chr7ris]

Can I use one ported and one sealed together?

[@weldsmoke1]

Yeah this is tough for me as well because I love the sound of both. I'm thinking 2 SVS SB2000 pros should make me happy. It's more my price range as well lol. Thanks for the video.

[@omnijacq]

Thanks a lot for this. I usually go 80% movies series and videogames 20-15% music. So it will be ported for me. I have an option to get a Klipsch 120sw or a svspv1000, which one you think will benefit me the most? Thanks. Keep on going Also I took your recommendation on the Denon x3600h. It's great. So

[@TechnoDad]

Thank you for watching Jacques!! I would go SVS for a subwoofer. Great pickup with the Denon.

[@johnpick8336]

As a Bass Player I have played both ported and non ported .. Ported equals "Baggy Bass" response v non ported equals "Focused and Tight" Bass response is how I hear it ?

[@Many_Mirrors]

Ok, now I know how to choose the right subwoofer.. but how do I choose the left one? pls dont downvote my dad joke

[@TechnoDad]

Lol!!! 😂

[@DJ_Force]

How big was the room at CES? You can rock a small room with a small sub.

[@edub8803]

I think you had a better experience with the small subs because four 6.5 inch drivers have a larger surface area than one 15 inch driver...

[@krane15]

Seal SW are the real McCoy. Ported came as a cheaper alternative to save cost and space. They also tend to be bosomy but some people like that sort of thing.

[@VicG78]

Thank you so much Techno Dad. So helpful! I'm literally in this situation right now. I'm leaning toward 2 big subs. SVS looks like the direction I'm headed.

[@TechnoDad]

Nice!!

[@jamegumb7298]

I built a 2,40m tall sub from a sewer pipe, tuned to 18Hz. It is okay, but lacks a bit in response, it is a tad slow it seems. It is ported. So I disconnected it from the amp I listen to music to and hooked it up to the pc. L4D2 and Doom 2016 never sounded better.

[@nathanhardy7008]

Though with a ported sub can't you just plug the ports and then use it as a sealed sub?

[@Boneyyym]

In a nutshell: Theoretically you can but in practice you'll find that it doesn't sound very good and doesn't have a good frequency band because the Chassis volume is finely tuned to the driver and ported subs need different volumes than sealed ones.

[@maxwelldowe8446]

Ported subs that aren't designed to have a sealed mode won't sound very good if you plug the port. However, if your ported sub has a sealed mode and is designed to be able to be plugged, it'll become a sealed sub and will sound good. I've owned both the svs sb and pb 2000 pro and the pb once plugged sounds identical to the sb. Get a ported sub that has a built in sealed mode in the dsp and you get the best of both worlds

[@madisonsinclair5123]

Okay, I really appreciate the Techno part of your videos. Now I have a question about the dad part. How do you keep the kids from destroying expensive high-end equipment? I am frankly terrified of allowing them in my house. I see my friends allowing their little ones to handle pricey AV Equipment and media, And I can't help but scream and wonder if they're lunatics. Scratched media, huge scratches and fingerprints all over digital media, huge scratches and fingerprints all over expensive big flat screen TVs. Here's where your dad part could really benefit a lot of people!

That helicopter chase scene is the best sustained Atmos I’ve ever heard!!! Can you damage a ported sub if you seal it or partially seal it? The Polk PSW-505 has a slot for its port. That slot could be filled with a kitchen towel or two. What “could” happen? I tried to stuff towels in my Paradigm Monitor p90 powered sub ports, the towels were being sucked into the port LOLOL.

Thank you! I'm trying to put out 3 videos per week. it's getting rough with all this snow I have to shovel, LOL!!

[@OxCart78]

By the way great video. I think from my experience, is that before you even get to what type, is how large is the space. I know that sounds amature, but I see a lot of people getting 15" subs for 1000 cubic feet rooms or 12" for 4000 cubic feet. Or the solution is if I add another sub it will just fix the problem. If you have a room that clearly needs a 15" sub, one 15" will sound better than (2) 12". Sure 2 will help even if it out, but from your sweet spot seat, that 15" will still move more air in that space.

[@TechnoDad]

Hi Eric!! Yeah, I totally agree and I made a video about that first, almost 1 year ago. I mentioned it in this video and linked to it as well. Here's the link if you want to check it out. I base the size of the subwoofer based on the cubic foot measurement of a room, so the volume of the room. here's the video: kzbin.info/www/bejne/noPVo36hrNNplc0

Nope! Have you seen my T-Shirt, "We need more bass" ?? Here's a link: bit.ly/2BA69MV

[@Oystein87]

No problem getting a sub that's great for both music and movies. A sub for music should go as deep as possible just as with music. Most important is that the sub has a really fast responce. So stay away from the really cheap ones. But a ported sub does not necceseraly need to be huge and a closed one is not necceseraly small. It all depends of the tuning etc. A closed construction can pump out as much bass and "rumble" as a ported one if it's built right and maybe even have a slightly larger box. And both needs alot of power to react quick as f*** and produce bass correctly. But a closed one always needs more power.

[@17Kozzy17]

I’ve had this issue in mind for a long while now. Finally a better eplaination on the sealed vs ported. Like you said it’s a constant battle. I want the best of the best. I have two def tech super cube 6000s. They’re pretty tight any amazing. But I’ve always had the thought of upgrading to a bigger sub / ported especially since my content is heavily movies.... since I keep hearing that is much better that route. I’ve also got couple audiophiles telling me that I have solid woofers and that I really don’t have to upgrade. Your thoughts!? Please advise!

[@steveb9974]

Thanks for the video and the series. I’ve had a velodyne dd-15 in a 2300 ft3 theater room and it’s onboard amp module has now started to hum after a few minutes of operation.

[@rolandrohde]

I never had serious trouble with my two Elac S12EQ subs, but I recently watched Shazam on iTunes (Atmos) and the first scene seems to do something bad to my subs. The seem to be delayed and cause some really ugly side noises in the scene starting at 4 Minutes in. I will have to investigate more, but I'm afraid it might be the passive membranes that can't keep up..

My listening room is 1040 cubic feet and so I'm looking for a 10" sub sealed. Can you tell me some options in this space? SVS SB1000 is 12" and even though the enclosure is small it'll be a lot of bass for this room. I'm mostly listening to music and want more of the tight punchy bass.

[@jimdowell1729]

hey hey! great vid as always! i am wondering if you could do a video on the how to's of crossovers and lfe's and all the settings you would need to pay attention to and consider when telling your avr when to kick sound signal to the sub and when to leave it on your mains. also, if there is a video hidden somewhere on your channel, i'd love to be pointed in the right direction! i have a sub that is as old as it was cheap and never looked back mostly because i was always able to shake the earth with it. its an old old magnavox that came with a 5.1 "in the box-plug and play" system from like 2000 haha. but i am not sure where to go on my upgrade. this video helped a lot and i will watch your other video on how to choose a sub, but i know once i do i'll need a bit more background on how to configure it to best go with 5.2(hopefully and fingers crossed!).4 system. Thanks!!

Hi Jim! I will, thanks for the idea!

[@Slickman2006]

I think it depends on budget also. If you have a get low budget I would advise to get the best ported you can.

[@TechnoDad]

True!

[@lakorai2]

Build your own sub to save money. Image Dynamics IDQv4 12 is $179. A box costs about $30 in materials to build. A 500w plate BASH class D amp is $249 from Parts Express. Costs less than anything from SVS, Klipsch. And you are able to make your own sealed setup. Most home audio subs are ported. Want a monster setup? Buy a big SPL sub like a Sundown, SKAR, SoundQubed etc. Use a ported box and then a Crown or Berringer external Class D amp. 1000+ watts for way less than a SVS.

[@marcosvictoria8815]

What about 1 and 1? 5.2.4?

[@wayneburger2318]

HI TD , I have a CAV 250W passive radiator 10 inch dual sub. This little box delivers big bass. You would think its a 12inch. I can imagine how those Dyna Audio's performed.

[@andyorozco6675]

Agree with you. I have a 115sw and I just got my sb4000 and the klipsch overpowered the svs. Not worth it 1000 in price. I'm getting another 115sw. I picked the sb4000 due to size and I though that 1200 rms will be more than the klipsch and wow I was wrong. Klipsch all the way.

Is it not a good idea to have (1) ported sub & (1) sealed sub in my theater?

[@googoo-gjoob]

sealed Sealed SEALED.

[@martyn5416]

What about a sub with passive radiators?

[@sukhsrboss5693]

Hi Techno Dad. I've been a member for a while and I really enjoy your videos. I've learnt so much from them down to the nitty gritty. I'm setting up my home cinema, I've got the 3020i front, 3090Ci and 3010i for rear. Ive decided to go with sealed subwoofer. As I listen to music and movies 50/50. Im stuck between 2 models, SVS Sb 2000 or REL ht1205. I've read great reviews about both, but I know you own the Predator 15", and that drew me towards the REL. The 15 is a bit out of my budget, so it's between the 12" and SB2000. Really appreciate any advice. Thanks, Sukh, London

[@TechnoDad]

Hello Sukh! It depends. I think if you were music over movies/tv, I would go with the REL. If you watch more movies/TV than listen to music, maybe the SVS would be better.

[@sukhsrboss5693]

@@TechnoDad Thanks! I take it the REL would be better than the SB1000 then? Are the Predators used mostly for music as well? Thanks again

[@JelleSchaffie]

Please youre advice. I listen music like Mark Knopfler, Dire Straits, that kind of music and also dance and trance. No hard core or hard rock. Listen space is 6 x 5 meter. Denon avc-x6700h Klipsch RP-6000F ll, RP-504C ll and RP-4000F rear. Ported or sealed? And the rel 1003 mk2 or SVS sb1000 pro? Which one will heve deaper bass? Thank you man 👍

[@TechnoDad]

I would go sealed

[@JelleSchaffie]

@@TechnoDad last week I bought the SVS SB-2000 pro. Love it 👍

[@treborreissul]

Thé best subwoofer is in sealed configuration. If you put in a same box has a ported.

Ported.

How many subwoofers needed in a home theatre.

[@saif333222able]

I have definitive technology supercube reference. Its sealed sounds like ported.

[@carloosgongora1701]

Techno dad nice video, i have 1 question for you, what are the Subwoofer brands that you consulted and watched their products in CES 2019 ?, to search their web sites for later buy.... thanks for your help

[@TechnoDad]

I went to SVS, here's a video about that (kzbin.info/www/bejne/p2PQeKStiKyEo68). Other than that, there weren't many specific subwoofer manufacturers there. I wish REL, PSA, or JL were there.

[@katalysis]

Just get a 15+ inch 1000+ watt sealed subwoofer and you will have the SPL, extension, speed, and accuracy.

[@in4chandru]

thanks, Channa! I have a question. I normally use iTunes to rent movie. This time I bought MI-Fallout Bluray, man the sound and the video quality are awesome compared to the rental from iTunes. My question is do you prefer to watch movies in Itunes or do you buy Bluray /4K discs?

[@TechnoDad]

Hi Chandra, great question! I prefer physical disc but I do stream movies because it is convenient. Sometimes I'll stream the movie and then buy it on disc, LOL!

[@in4chandru]

Techno Dad that’s exactly what I did. Lol!

[@harta_1509]

Buddy. What about my room 15 by 19 feet’s? I’m thinking seal two 12’. Or one 15’. What do you think ? @ techno dad

[@TechnoDad]

If you have 8 foot ceiling, that would be over 2200 cubic feet, so I would say dual 12".

[@POTE0831]

That's why I love my pb-4000 use the plugs have seal or ported

[@TechnoDad]

I change it up from time to time but I notice extended works better in my room.

[@POTE0831]

@@TechnoDad same here

[@evanwelder]

What’s you’re overall thoughts on the pb 4000? I assume you’re just testing it out for your viewers. Would you buy it if you weren’t testing it or would you go smaller. Also how is your experience with just one subwoofer. I’m trying to decide between the pb 4000 and pb 3000

[@TechnoDad]

Hi Evan, great question! I probably wouldn't get something this big. I would rather go with the PC4000 as it would fit better in my living room. This one subwoofer is more than enough, and as for going dual I can't really fit anything more.

[@georgefremd1802]

Forward or downward firing subs?

[@TechnoDad]

I would go Forward.

[@darrellhaslett1333]

Is it advisable to use both a ported sub & a sealed sub in the same room?

[@TechnoDad]

Hi! No it isn't. You need to have either both sealed or both ported

[@conraddevera]

Just returned sb 1000 and got the pb, I like the pb more. Wish I can get the 2000 but it's too damn big

[@TechnoDad]

Yeah, those ported 2000s are pretty big!

[@markdance574]

Good video - thanks . Should all good systems run two subs? Also what does Technodad think of this months issue of What Hifi - spec their Klipsch review which didn’t go that well ?

[@TechnoDad]

Hi Mark, it doesn't necessarily matter, single or dual sub. As for the What HiFi article, I haven't seen it. Do you have a link?

[@markdance574]

Hi Sorry I’m not technically advanced but I think if you type in What Hifi in your search engine the article should be on their web site - if not check out the magazine issue dated March 2019 pages 12-13 the items tested were the Klipsch reference base home cinema package in 5.1 configuration ( r-620f ,r -51m , r-34c centre and r100sw ) rated at £1646 English pounds reviewed at a average 3/5 stars . Would love to get your views on English brands like Kef and Monitor Audio in the future .

[@MrDavydavid]

Great video thanks

[@TechnoDad]

You’re welcome!

[@taconysr4628]

Great video! Question: I have a svs sb-1000 currently and want to go dual. Its in a small basement home theater and I watch movies/tv shows 90% of the time. Was thinking of just going with another sb-1000 but would a pb-1000 work with a sb-1000 as the dual? Since I’m watching movies most of the time seems pb might be the way to go.

[@BrandBrian]

I have the same question, 3 years later.. is one sealed and one ported a good idea? what did you wind up getting for the 2nd sub?

[@brianlehr78]

What about 1 of each working together??

[@TechnoDad]

Not sure that would work or how to dial that in, Brian.

[@freddyg1210]

Awesome video! Just became a new subscriber. I just saw the other video you linked on room size. I'm building my house in the next month and I'm building a 14'x20' theater room (9' ceiling). I have a $2,500 budget for just the audio. I plan to pre-wire the room for future upgrades. I want to pre-wire in the front, sides, back and ceiling. It will be mainly for movies and some music (about 75/25). What setup do you recommend I start out with, with the info I've provided? I would love to feel the bass! I've enjoyed your content! Thanks so much!

[@OxCart78]

I have a room about 1,000 cubic feet larger. My advice for you is go no smaller than 15"!

[@freddyg1210]

@@OxCart78 Thanks for the advice! I appreciate it!

[@TechnoDad]

Hi Fred! I would go with dual 12" subwoofers for that room as you have just about 2500 cubic feet. I would try to draw out where you would place everything in the room. That way you can get an idea of where everything will be. I would go with a 5.2.4 Atmos setup as I don't know if you'll want surround back channels, but you should have room for a 7.2.4 configuration. But that's up to you, you know? Figure out where you couches would go, and how many there are. Also think where you would put the equipment. Do you want to have an equipment closet or is everything going to be out in front of you? Just think about it, should be pretty easy. You can also email me to get more detail: technodad55 at gmail.

@@TechnoDad Awesome! Thank you so much for your response! I will definitely email you soon. Look forward to more videos!

[@MrPaultiwanger]

Nice information. What about listening to old R&B and Motown?

[@TechnoDad]

Hi Paul! I would go with a sealed subwoofer and if you have a really large room, maybe two would work. But again, I don't know what your room is like, so I can't say for sure.

[@quadsnipershot]

So it comes down to music or movies then, what type of music?

[@TechnoDad]

Hi! Yes!

[@Roof_Pizza]

They say to 'get two' and I'd agree 95% of the time unless they are cheap subs. 1-$500 sub is better than 2-$250 subs. Then, sometime down the road, get another $500 sub.

[@mosinatic2011]

So ported 8 inch powered polk sub vs 12 inch sealed powered svs sub with lfe input?

[@TechnoDad]

I would go with the SVS

[@jasper23454]

What about ported subs like the svs line that allow for sealing ports. Are they the best of both worlds?

[@voodoo9077]

Only issue with that how large the subwoofer cabinet size. Almost double compared to a sealed

You can do that, but as Voodoo stated the cabinet is very large.

Do you generally recommend one or two subs?

Dave Johnson don’t be a fool, always go dual! 😂 only joking. Just made that up. Dual will always have benefits, but it is possible of course to tune a solo sub to a room perfectly. 👍🏻

[@80redbarron]

You're in rare form tonight! I figured that was what you would say.

[@TechnoDad]

Hi Dave! Duane pretty much summed it up. You have more benefits when going dual as you remove any nulls in your room and you'll have more even bass around the room.

richanmel I tried this. And it was a mess. Image standing between 2 rooms. One room is playing slipknot at 50db’s, and the other room is playing say....an r&b album at 50db’s.....if you stand between both rooms and listen simultaneously, that’s what you experience with one ported, and one sealed. I tried this. Was shocking. Total mess. Kicked myself a lot , and wrote it in my top ten things you should NEVER do, right above sticking your finger in a live mains outlet like this 👉🏻🗣💥🔥. 👍🏻.
