That pic gets me all excited. I have been considering two S3611 subs as end tables near-field to my sofas and recliner (where my current end tables and lights are). I was wondering what kind of smoothing that would provide me with the corner loaded S7201. It's okay to dream.
Can you put a second s7201 where you are standing, kitty corner from your current one? It looks so lonely there, all by itself :)

I wanted to give props to Tom and PSA for their trade-in/up program. When I was in the market to upgrade my old Mirage BPS400 sub several years ago I looked at several ID companies and reached out to each one. I was only blown away by 1 company with how they answered all my annoying questions and concerns and put me at ease with making a large purchase from an ID company. That company is POWER SOUND AUDIO. I would have never been able to go from 1 XS30 to dual S3600I seamlessly if it wasn't for Tom and PSA. Each upgrade/transaction went smoothly and gave me that kid on Christmas day feeling. Thank you again, Tom and Jim, for all that you do for us. We greatly appreciate it.

Yep. I'm sure I annoyed the hell out of Tom back when they were just starting SVS with all of the email questions and he never missed a beat or showed any signs of aggravation (at least to me :p). I had some of the very first SVS subs and purchased from them multiple times. Every time, Tom bent over backwards day and night (what company responds to emails at 1 and 2 am?) to provide all of the info I requested and was happy to help. It's amazing that he has been able to keep up that level of customer support this many years later. Tom and Jim also helped me out BIG time on a product that was WAY out of warranty. Simply amazing! I tip my hat to both of these guys. The level of customer support they provide is simply unheard of in this day and age, which makes it all the more impressive.

Their commitment to American Made is very sweet icing on the cake!

I have a question regarding room gain and port tune.

Let's say sub "x" is an 18" with a 17hz port tune. If I were to put 4 of those, one in each corner of my room and I were to get a gain of about 1.5hz per corner due to room gain/corner loading....would i be hitting around 11hz strong?

I know I've read that no matter how many of the same subs you add they would still cut off at port tune, so would this be an exception?

Super noob question, sorry.....

Mike I remember when you first got the XS30 and followed your journey ever since my friend, Tom had me from hello Jeff how can I help you today from the first email I sent and I got a reply that same day. You can understand my surprise and trust in PSA as I was coming from Epik...................:) I'll be sharing my experience with the new V36s soon which I might add went seamlessly as well as did all my many transactions over the last 6 + years. Initially I thought the V36s were huge and would stand out like a sore thumb but the missus asks every day if I moved them somewhere else and I have to show her where they're at, they literally disappear until you power them up and still aren't localized.............:D Enjoy my friend...............

Cheers Jeffrey

You don't gain any extension per se but if you were to use a mini dsp or some form of eq and apply a low shelf filter, you would gain some more useable output down low. It Won't change the tuning point but you will be able to lift the low end up. For example, when I added a V1801 to my 3 XV15, my low end response lifted up enough to get me reference capability down to 13hz opposed to 16hz, but the "knee" of the response didn't change. The roll off still starts at the same frequency of the subs tuning point. Hope that makes sense.

Let's use an in-room output compression of a V1801 for example:



The graph hasn't shown compression yet. Let's just assume that this compression sweep was taken with one V1801 at a corner. According to the graph, the V1801 can hit 105dB @ 15Hz and 99dB @ 10Hz.

Let's just say you want 110dB of meaningful output from 10Hz and up. Right now, you have meaningful output down to 17Hz or so. Everytime you double the number of subs, you gain an average of 6dB.

Therefore, when you go dual V1801, you can hit 111dB @ 15Hz and 105dB @ 10Hz. Now you have meaningful output down to 15Hz.

Then when you go quad V1801, you can hit 117dB @ 15Hz and 111dB @ 10Hz. Now you have meaningful output down to 10Hz.

Typically below port tune, the FR drops like a rock. When all else being equal, you will get higher output at a lower frequency by going with the sub with the lowest port tune. Therefore, if you want meaningful output at say 10Hz, you are better off getting a 12 Hz tuned sub than a 20Hz tuned one.

Now, F3 extension is defined as where the FR drops by 3dB and does not come back up. Regardless of how many V1801s you have in this room, the FR still drops by 3dB at around 17Hz. Therefore, adding more V1801s does not improve the extension.

This is a per-subwoofer spec definition of "extension" vs. in-room FR of all the subs combined though, right? Because at some point wouldn't you have enough additional output to be able to boost the lower frequencies including around 17 Hz to where the 17 Hz mark still falls within 3 dB of the upper frequency range, and thus extend your overall F3 extension to below the tuning point for each sub?

Well, the typical FR refers to anechoic or outdoor, in room FR usually gets you about 2~3dB lower for subwoofers. In this case, the V1801 is tuned to high teens and the in-room extension is 17Hz or so.

You are talking about meaningful output, which is different from the classic definition of F3 extension.

That is sharp.

David just get a 7201, lay it on it's side behind your MLP and let it handle all the sub 15Hz bass down to single digits with authority, maybe it was my room 2700^3 but the 7201 excelled at gut wrenching SUBterranean bass.
What is driving you to achieve this type of bass in your place, do you fell lacking now with what you have, maybe I missed the reason why you feel the need..............:)

Here's the 7201 at 110dB at 6 Hz in my place at -9dB MV......clean with more to spare......lots of cabin gain helps.......Just plopped in the left corner, no EQ, sweeps taken at MLP 15' away, stopped at -9dB because mic was starting to clip.......you might want two though.....:D

.... or as some of us have said, trade the V subs in for a pair of S3611's, or 2-3 x S3010's - IMHO this beast seems to get overlooked a bit nowadays for the 18" models

I agree he should try the S36s or S30s, they would be almost invisible in his place plus provide the deep bass he's craving and these subs will take his music listening to new levels........................:)

Just a heads up for anyone considering the dual opposed 15 or 18 inch designs---we have a number of each(S3000i and S3601) in the outlet. And we're getting into fall now so we need space...:) Pop into chat/email me for best pricing.

I got my subs to give some great chest thump with the song “Mr. Carter” by Lil Wayne. -5mv and subs at 1:00 and -10 trim. Was sounding and feeling like concert thump.

Not a huge rap fan but I came across it on tidal.
Dave

Edit: wow, the song 6 ft 7 foot by lil Wayne started off chill and when the bass hit on my subs, my teeth were literally chattering. I wonder if the sealed subs would sound as good as that... the bass must be around 35 hz. Someone play it and let me know (none of that YouTube streaming crap)

I would have to think in the 30hz to 100hz range that dual S3611's would sound pretty similar (excellent) and have at least as much output as a V1801and V3601

Here is an odd question-

I have an unusual floor plan.

My tv is in an area with a 20 foot tall peaked ceiling. I am using 2 S3000i currently.

Due to the room layout, they are basically end tables- one on the right of the couch and one on the left of the loveseat.

I don’t have any other spots for them in this area- but I do have a small loft overlooking above.

What would happen if I bought a 3rd S3000 and stuck it up on the loft?

I’d have to use a wireless transmitter, and I guess a Y splitter off the receiver to feed it.
