Great video. I have a 15x15x10 room and a 12" was really struggling especially with the tower speakers and power going to them that I have. I went up to a hsu 15" VTF-15H MK2 and it is outrageous by comparison to my old 12" Klipsch. Way more rumble and punch. It actually pressurizes the room, I always say get as much sub as you can afford and I'd also say over do it by a lot rather than under do it by a little. You can always adjust it down...can't go past max.

[@TechnoDad]

Hi Brian! Well said!

[@chrisjones6165]

Still have the hsu? How's your opinion of it now? What's low end like. 30hz and below.. 10hz isn't a huge deal for me but 20hz is a must and must do with authority.. why I'm replacing klipschs now

[@brianhorrorfan]

@@chrisjones6165 no idea what the Hz range is as I've never checked or worried about it TBH. I can tell you this, I still love it, it still works flawlessly, and it rattles my bathroom window which is on the same floor about 25ft away from the sub through two walls while watching the new Dune. The options are great on it as far as customizing it to your specific needs to so if you contact HSU they can tell you how to set it up with the EQ and other tuning options to fit what you want it to do..... But all that being said I would look at the new Monoprice monolith 13" thx Sub. Due to the prices of HSU going up and having pay for shipping the HSU is going to run you $1354 now. The Monoprice monolith 13" thx is on sale for $1549 right now with free shipping. You get much more power and if you read the audioholics review it is a monster that dips down to 10-12hz in room at insane SPL. For my money starting new I'd 100% go the monolith 13" thx or 16" thx for $1550/$2100 route .

Channa, your the shit man!!!! I'm so upset I didn't find your channel sooner. You've got everything!!! Best channel by far.

[@RESURRECT2]

1250 cubic feet - I think about SPL-150 (15" sub), I live in a flat, so won't be maxing this. Will it be ok or should I AVOID it, because sound will be worse than with 10" sub? Or I can get 15" and sound will be better compared to 10", just won't be able to use all this power?

[@Aboode007]

You should put both metric and "American" measurements in your videos for all your international viewers.

1500 Cubit Ft = 42.5 cubic meters 3000 cubic ft = 85 cubic meters

Would you go with two 10’s or one 12? My thoughts are that dual anything will out perform a single due to balance

[@tf1490]

forsure two 10's. quality matters too but still unless you want the foundation of your house to rattle

This is great definitely measured square feet before and not cubic will be redoing my measurements although I'm pretty sure I need a big sub for my open basement with 8 foot ceilings. It was 600 square feet.

Hi Technodad. My room is 28' x 10.5' X 8.5' so 2500 cubic ft (enclosed) But want to build an additional wall (similar to Superdave) to create a sort of media closet behind my TV. creating a new 5X10.5 closet. (with the tv wall being 10.5 feet long) So room changes to just over 2050 cubic feet. What do you think for this set up? dual 12s? I am a little in danger of running out of wall space with a 75" TV and two Tower speakers (unless I place subs under the TV?) It works, but the wall is PACKED and I'd like to get a nice floating TV stand,console under the tv. I know I don't HAVE to place subs at the front of the room, but I really like the look.

This video was a great idea. Worth making BUT...while they are general guide lines...we know one "12-inch (driver) sub" is not the same as the next. One might have more power. One might have nicer built-in amps, less rigid cabinets...etc. Then there is how the room walls were treated for sound--were they sound "suppressed"? Do they have absorbing and reflective panels? Does it have wall-to-wall carpeting? How much furniture...etc. So many variables... And where did you come up with...1500 cuft room should have 2 10" subs...etc.? Just personal experience? Curious.

Yes I got a few questions for you. I have a BIG MANCAVE almost 9,000 cu ft. My single Velodyne DEQ-10r subwoofer which has 195 watts RMS and 390 watts dynamic which is placed in one corner does actually pretty good. However, I do not get the heart rumbling, wall shaking like I should for movies, I am mostly into movie watching a little music but not so much, so bass in music I don't really care it its there or not. But movies is a different animal. I am looking into replacing the subwoofer though. I don't like the footprint of the SVS PB 4000 (to DAMN big) and the PB 3000 is a little more tolerable but not to much. Here is the question. Question about the SVS PC 4000. Do you think that one PC 4000 should take care of the problem, I am thinking this has 1200 watts RMS and 4000 watts peak, at the Minimum power out it still is putting out 6 times the punch of the Velodyne. The PB 4000 is just to damn wide and deep for my liking. But the PC 4000 has a great footing to it. I understand that its like a used glove you get use to it and don't want to change gloves. I have talked to individuals at SVS doing my homework and research and they are telling me that I should run duels but I don't think its necessary I am thinking its a sells pitch to spend more $$$ lol. I am thinking since the Velodyne does what is does with the minimal watts it does put out ONE bigger sub will do great. I am also in the process of resetting my Home movie system. I am trying to reset my 7.1 Surround system. I am running a Marantz A/V receiver model SR 6006, 100 watts per channel. I need some help in the speaker settings. the following is what I have set it to. But I am not sure if these are correct. can you help me out and give me the proper settings for the best quality. ...... AIM8 Two In-Ceiling (Speakers) A/V Receiver / Processor: Speaker/Subwoofer Crossover Frequency (Hz) 80 Hz Stereo Pre-Amplifier or Receiver: Low Pass Filter Frequency Setting (Hz) N/A Hz Low Pass Filter Slope (dB/octave) N/A dB/octave AIM CINEMA ONES (Front) A/V Receiver / Processor: Speaker/Subwoofer Crossover Frequency (Hz) 80 Hz Stereo Pre-Amplifier or Receiver: Low Pass Filter Frequency Setting (Hz) Hz Low Pass Filter Slope (dB/octave) /octave AIM LCR 1 (Center) A/V Receiver / Processor: Speaker/Subwoofer Crossover Frequency (Hz) 80 Hz Stereo Pre-Amplifier or Receiver: Low Pass Filter Frequency Setting (Hz) Hz Low Pass Filter Slope (dB/octave) dB/octave I am very open minded and keeping all my options open. But I really need help with this situation. Also I have high frequency hearing loss due to my 20 years in the Military combat tours etc etc. I don't want to lose the rest of my hearing so I am just a little concerned about the subs output. What is your opinion on this.....I look forward to hearing from you.

Hi Ernie!! It use to be that you could take the diagonal measurement from the TV and multiply that by 2.5 and that would be the ideal place to sit. That was for a 1080p TV, but now for 4K, they are saying you can go with a bigger TV in that same space. Does that make sense?

My room is 18x14x8. A little over 2000 sq. ft. Several years ago when I first set up my home theater in that room, I tried 2 8" subwoofers which didn't work for me. So, I went with a single 12" SVS sub which I loved. Recently the amp in my sub went out. So, not learning from my first try at dual subwoofers, I bought 2 10" Klipsch subwoofers. They just couldn't reproduce the bass I was accustomed to with the SVS. So, I ended up returning the Klipsch subs and buying another 12" SVS which I love. The plan now is to eventually replace the amp in my first SVS sub and try dual SVS subs. A single 12" SVS sub is enough for the room, but I want to try dual subs just for fun.

That sounds like a good plan!

Hi, I’ve short listed these two sub woofers, the Polk HTS 12” and the BIC America F12. I haven’t auditioned any of these yet. My room volume comes around 2000 Qubic. I have this Polk S20 Bookshelf Speakers for the front channels. I am using it for purely music purposes and I have plans to upgrade the system to 7.2.2 or 77.2.1 later. So my question is which sub should I choose for my room ?. The sub should sound excellent for music(like EDM) and movies that is the end goal. Please suggest one!

Hi Manoj! I would go with either. They both look like solid performers with a ported enclosure which will give you better bass extension for both EDM and movies. So pick one and see how it works. You should be able to return it if you want to try the other one. OR...but both and try them out, and keep the one you like.

Unfortunately returning will not be possible in my area. and I can only get the audition of the Polk HTS 12 at most. because BIC F12 is not available near me and have to order online and they will not accept return!. so I have to depend on other experienced peoples advice on this situation. so please take this in consideration and replay

Have you tried using a receiver as a Pre amp and say 4 channel poweramp with Active crossover with passive dual 10” peerless subs the poweramp will run my subs so I don’t need plugs where I put the subs.

I think you should probably be good with another PB4000. 1200 watts RMS x 2 should be enough to get that impact you're looking for. Yes, in a perfect world, you would want the exact same sub to get rid of any dead zones in your room.

[@335i101]

Techno Dad Thanks boss! Also thanks again for hooking me up with your speaker guy in Kentucky!

[@TechnoDad]

No problem!

[@kenzo06ful]

What would you recommend in 1500 cubic feet seald concrete room, 100% Movie watching I'm gong whit duals Ported vs seald. I want the best chest slam for that room. high volumes and low volumes. can consider 18" subs also..:-)

[@ChrisRash]

I'm at 5500 cubic feet. Do you think dusl 12" subs would be okay?

[@TechnoDad]

Yes! Dual all the way!

[@ChrisRash]

@@TechnoDad thanks for the quick reply! I just discovered your videos. I love them. Do you think that 2 x 12 would be sufficient, or would I need 2 x 15? The room is a rectangle, but only one end of the room is the viewing area. The other end is just open. Thanks!

[@hernandeztaverafabricioale637]

My room size is 1150 ft**3, should I go for dual 8" or just one 10" sub?

[@andynelson2340]

dual ported 10's (i'm a bass head though)

[@elsoldado13]

What are your thoughts or opinion on in-wall subwoofers

[@TechnoDad]

Hi! I've never heard any in person, so I don't think I could say.

[@victor6207-d6h]

Question for you guys. I have a room that's approximately 18 feet deep 7 and a 1/2 feet ceiling and and 12 feet wide. I plan on using two 12 in subwoofers for a dedicated theater room which I'm building. Am I going overboard ? I know everyone swears by multi sub which is finally why I decided to do it upstairs in my living room which sounds absolutely amazing. Only problem is I don't want to upset the wife and disturb the kids with a loud noise. Which is why I'm building downstairs in the basement.

[@jdubdoubleu]

My movie room is downstairs in a finished basement with ceiling tiles. Will the tiles effect my sound in a negative way by much?

[@TechnoDad]

That's a great question, and it may make a difference, but I'm not sure you would notice unless you were REALLY listneing for it.

[@OxCart78]

Techno Dad, does the viewing area reflect the size of the sub? So if your airspace is 4,000 cubic feet but your sitting 6 feet away from the subwoofer. Could you still get by with a smaller sub than you recommend? Like a good quality 12"?

[@TechnoDad]

Hi Eric! Yes, it probably does. Since you are so close to the sub, one 12" should. Now if you were trying to get even bass in all seating positions, that might be a bit difficult.

[@samtobin3487]

Thanks for posting the vid. I have Elac Debut 6.2 front L and R and center. I want a sub but the reviews of the Elac Debut s12eq are just OK. Ive been looking at the Klipsch Reference R-112SW. Is there anything i should be aware of before mixing brands like this?

[@TechnoDad]

Hi Sam! No problem using a different sub than your other speakers. Look into SVS subwoofers.

[@ThujanK]

Don't you have to consider how low a subwoofer hits and the power it is fed? I have a dual 10 inch subwoofers that goes down to 23hz with 300 watts of power and 1200 watts dynamic. I do understand that bigger subs are able to take more power and should be hitting lower frequencies but end of the day it's the actual specs that matter right? My room is 3000 cubic feet approximately and it opens up to other areas but I had to set the volume on the sub to 1/2 and on my receiver at - 3db for the low-end to not overpower the speakers themselves.

[@TechnoDad]

Yes, all very good points. Balance is a topic I got to in another subwoofer video, and probably what I'll get to in this series as well. Getting the proper balance between speakers and sub are very important as you don't want to overpower the sound with too much bass.

[@007vsMagua]

I have 8 foot high ceilings. My room measures 22'L x 12'W x 8'H = 2,112 Cu. Ft.. I went with two 10" subs and that seems to work pretty well.

[@TechnoDad]

Nice! Glad to hear it and thank you for sharing your experience!

[@hiboost2453]

I built a diy 15” sub tunes to 28hz big box in my small room 12 x 12 x 10 .. 200 watts and that’s perfect for my room, for the back listening area at least lol anywhere upfront is nearly a bass dead zone but at least it shakes everything haha 😎😝

[@TechnoDad]

lol!

[@shawnulery51]

Techno dad I bought a pb 16 ultra. I feel it should be louder. I told svs this so they sent me a replacement amp. It still does not meet my expectation from what I here from you. I thought this speaker would blow me away and it’s not. Do I have a faulty sub or is my expectations to high from your reviews.

[@TechnoDad]

Hi Shawn. I'm curious, what's the volume of your room, and what settings are going on in you AVR? What level do you have the sub set to?

[@shawnulery51]

Techno Dad my guarge is 24x30 I have the sub at -10to-6. My avr is set at 0db.

[@RotNcroch]

I have definitive tech. 8 inch sub and also a paradigm monitor 7 10 sub. The paradigm is crazy loud!

[@iamdjziggy]

Hello Techno Dad... I have 2800 cubic ft living room... what if I put 2 10in subs... will that work?

[@SuperCaptainMOo]

Is dual 10”s good for a 1600cubic feet room?

[@TechnoDad]

Yes, that would be great!

[@Joe4USMC]

Thank you for all of the great videos!

[@trboogie2012]

Great video but I noticed you only put up SVS subwoofers. Have you ever looked at JL audio subwoofers the E Subs and the Fantom? What are your thoughts if you have. Next thing is a lot of people are raving about dual subs in a room as opposed to one big 12 put two tens?

[@TechnoDad]

For home theater I've had Celestion, Klipsch, and SVS. For car audio, I've had Orion, Boston Acoustics and JL. My best car system had three JL 12" subs in a custom fiberglass enclosure built into the spare tire well with a new false floor in the trunk. Very awesome system, until the car got stolen, lol!! I would love to see what JL has for home theater, and I'd also like to try out Velodyne subs. As far as dual subs, it's about even bass for all seating areas.

[@trboogie2012]

Techno Dad lol sorry about the stolen car. but if you do get a chance check out JL Fantom series. I went into a audio store here in New York to listen to it and it was absolutely amazing well built very deep bass and clear it wasn't distorted. definitely interested in hearing your thoughts if you get a chance to check it out

[@jdmsz9378]

Techno Dad seems like people with good sound systems inside their car eventually gets stolen. My father had a good car sound system back in the day and it got stolen as well. That's why I can't get into car sound systems because it's too easy to steal. Usually cars with a Bose sound system is just enough for me

[@TechnoDad]

Those JLs are pricey!! No way I can afford to buy one of those for the channel...yet, LOL!

[@trboogie2012]

Techno Dad lol yes they are very pricey... but don't buy one just check it out at a dealer if you can... and no worries in a matter of no time you'll be able to get one for the channel your channel is growing so fast and you're putting out good content so it will only grow faster. Keep up the good work

[@hi-fihaven2257]

Hey man another great video! Great, and very useful information! Makes figuring out what you need for subwoofer setups very easy! Awesome.

[@TechnoDad]

Thanks man!

[@leonrotedits]

My one is 24 q2m big and i need a pretty low Subwoofer ofcourse the Room is like tuned to 18 - 30 Hz

[@ferdous_h]

You didn’t said anything about RMS power... How much power should I have for a 1250 cubic feet room?

[@terhill1]

Hi, can I use 3 ohms speaker to a 4 ohms amplifier? Thank you

[@TechnoDad]

Hi! If the Amp is not stable at 2 or 3 ohms, there might be an issue. Not really sure. What are the components?

[@Alftar]

Depending if the driver is a dual voice coil. You can effectively drop the speaker 1 ohms up or down if it’s wired in either series, or in parallel.

[@lefamiglia2392]

Can you create the same video again but this time mention RMS power + sealed/ported?

[@ulflarsson9693]

My svs sb 16 u is the right sub for me. 😊👍

[@jaysidhusidhu8874]

Hi my room has cubic 1200 volume how much max power sub i can use one or two thanks.

[@TechnoDad]

Hello Jay, I would go with a 10" sub with 200 - 300 watts RMS. You could step it up to a 12" if you wanted. The SVS SB-1000 (amzn.to/2S5gvuR) is a good one at $499.

[@jaysidhusidhu8874]

Thanks a lot

[@TechnoDad]

No problem!

[@jaysidhusidhu8874]

One more quetion please can i put all same speakers for all 10 speakers for sorround, back, front ,height channels. What is the best option budget for these speakers thanks mate.

[@TechnoDad]

Yeah, you could use satellites for all your speakers and then a 10" or 12" sub. That should work. Have you looked into SVS's Prime Satellite system? It's a 5.1 system, but you can add more satellites as your needs grow. Here's a link to the 5.1 setup: amzn.to/2q6p24b

[@ENDFLASHYTTelugu]

1500cubicfeet how much need watts of 10inch subwoofer

[@amdenis]

What would you do for a 24,000 cu foot room?

[@TechnoDad]

put as much in there as possible, lol! That's a HUGE room!

[@amdenis]

​@@TechnoDad Thank you so much for the quick feedback. Yes, I kind of figured that, but I have two specific questions that maybe you can help with. First for “reasonable listening levels across classic rock, traditional jazz, prog and some classical, would I be better-off with a 2-3 large 16 Ultra SVS subs, a greater number of 4000 series (e.g. 4-6), or even more of the 2000 series (all add up to about the same price I’ve budgeted for). Finally, the room is very asymmetric with mostly non-parallel walls and such, other than the floor-to-ceiling axis (slthough it has large cove molding along the circumference of the ceiling). Also, it is open via 5-foot by 12-foot hallways at two places, and has a connected kitchen area, open wet bar/pantry and a partially recessed sitting area that I am sure create areas of different fundamental resonances at various gain function levels. Given all of this complexity, I am at a loss for how to determine optimal subwoofers placement using standard methods- other than trial and error (which is definitely NOT my first choice). As such, do you have any recommendations in terms of process, software or otherwise to facilitate this?

[@melcuemba03]

Fantastic Video.....the best....

[@TechnoDad]

Thanks Mel!

[@s-zilla8184]

Great video! I was wondering if there is any way to plug a active sub into a Lg C9. I heard you can do this with the Song OLED but not the C9.?

[@hellR1de]

Hi Channa! I wished I had discovered your channel sooner. Plenty of informative useful videos. Keep up the good work! In this particular case, I'm interested - sorry if you already replied earlier - in knowing how you determined the 1500 cubic feet threshold, between a 10" and 12" sub. Did you measure the db outpout?

[@TechnoDad]

It's more of a guideline. I read a few different remarks about subwoofer size in relation to room size and went off my evaluation of my room to come up with a guideline.

[@jamesf1505]

My family room is 19'6"×19'6" with an 14' extended hall way. I'm thinking of adding polk audio HTS12

[@Kablemodem]

How many did you get?

[@romanlewandowski9616]

Good information and it was simply explained thanks

[@TechnoDad]

Thank you Roman!

[@stephanierodriguez7395]

Yeah I agree those monoliths are no joke!! ..

[@EDKsurly]

Is it ok to put my subwoofer behind the couch?

[@Angel-AbC9]

Tech dad where do u get your illuminati triangle shirt from... Even if its just a company advertisement they are still the triangle and all seeing eye at the top

[@TechnoDad]

Lol! It's a Daft Punk/Pink Floyd shirt. I found it on Facebook somewhere.

[@MasterDrhd]

i kinda have the same problem you have but just my kitchen. its connected to my tv room. I have two 15" and there awesome but i want more.

[@Hayden-ji7fb]

What kind of subs are they and how many watts?

[@David25522]

Awesome video!!!! Been waiting for one like this!!!

[@TechnoDad]

Thanks David!
