I've never posted that opinion before but here it goes.

Background: I've first got an SB12-NSD then moved on to dual PC12-Plus. That's a pretty large step-up, but that was the cheapest solution if I wanted to try 1) dual SVS subs and 2) variable tuning. It took a while setting up the dual subs (due to one being DOA), but I achieved proper results only when the two subs were integrated. So I was not able to go from one to two subs almost instantly and see a night-and-day difference.

Sure, bass is now more uniform across the room, and I got plenty of headroom. But I guess my expectations were a bit high: there still are spots within the room where bass is way more pronounced, or way less, than others. At the listening position though, things are great. Headroom is nice as I can play as high as I (or friends) want without any fear. Though, duals add a maximum of +6 dB SPL (in practice, about +4.5 dB for me), not +20 dB.

It's also true that dual subs create a smoother frequency response. I've measured. But, it can also create complications at the crossover frequency, as it can be hard to adjust the correct phase/distance of two subs with respect to 2, 3 or 5 other channels. Even Audyssey SubEQ HT is not perfect in that regard. And frequency response dips or peaks are still there -- don't expect a totally smooth +/- 1 dB FR just by going dual. Sub EQing is still needed (although duals may help a lot with nulls that can't really be corrected with EQing). Likewise, location of the dual subs is still important, so it just doubles that particular issue biggrin.gif

So going dual has lots of advantages, but it's not a panacea to all sub-frequency problems. I lack to will to turn one sub off and recalibrate my setup and switch back to duals to test if the result will be a night and day difference (sorry about that -- perhaps one day I'll do it, and also test sealed and 20 Hz tuning biggrin.gif). But to me, I hate to admit, I don't think going duals is critical. It's a (very) nice to have. I found having sub EQing capabilities provided more immediate improvements in my case (I started out with a Pioneer AVR that did not EQ the sub; I first added a Behringer DSP1124P -- aka BFD -- then switched to a MiniDSP, then to Audyssey MultEQ XT32 & SubEQ HT equipped AVR, and the largest step up was the inclusion of the BFD).

I am thinking about what subwoofer(s) would be best for my set up. With such a small space i am leaning towards dual sb1000. Just curious this would "pressurize" my room.

Your room is indeed quite small and dual SB-1000 would do nicely there. But, for the same price, and if you're using the setup mostly for home theater, and assuming you don't mind the increased size, I would go with the PB-1000 for the added extension.

Going with a standard basement ceiling height of say 7' or even 8' your still in the small room category, provided the room can be closed off to the rest of the house. If it can IMO a pair of SB1000s would work very well in that space. You should see some decent room gain in the low end, especially if you can place them in the corners.

I'm curious,why doesn't svs use anything bigger than a 13" driver?

The difference in sound quality is quite staggering as one feels their room totally open up and literally come alive. Night-n-day, like a light switch.

Too bad adding another sub isn't as cheap as a light switch.
post #13386 of 15702
Ok, what do you recommend. I have a PB12-NSD now. Should I send it back and upgrade to a PB2000 (about $170) or wait and add a PB1000 ($450 outlet) and keep the PB12-NSD? Room is 16x16 with 8ft ceiling with one hallway opening. I am looking for more mid bass than anything.
post #13387 of 15702
Yes the ceiling would be 7.5 feet in height. The subs will also be in the front corners. Currently the plan is to build 2 "columns" that are about 24" wide x 16" deep that will be wrapped in AT fabric that will house the speakers and subwoofers. That is the reason for the small foot print to be able to fit the subs in the small space.

A pair of SB2000s or a pair of SB13 Utlras would also fit. biggrin.gif

Since I love spending other peoples money, I would get the PB2000 with the intent of adding another one later.

Although I noticed a difference when I added a second sub, I noticed more of a difference when I took one away. I bought a PB12-NSD to replace my old sub. While I was trying to sell my old one, I kept it in my system. Then when I sold it and took it away. I couldn't believe my ears and ordered a second NSD the same day.

I have no idea about half of what you guys are talking about in here but I just got my new PB-2000 today and it is outstanding. Wish I could give you some rewish mlp db octave slopes but I just listen and enjoy. Great product and shakes the room, looks great.

Congrats! That's the most important thing. You like how it sounds.

nashou66, it sounds like you have two PB1000's is that correct? What are the differences you noticed?

I have a PB1000 now, and I'm pondering a second sub. I kind of like the PB2000, or maybe another 1000. I'm interested in the experiences of those who have dual PB1000's and also those who have a PB1000 in combination with a different second sub.


It just evened out the bass and added a little more output. It added more feel to certain scenes, but even one did that compared to my older Velo. But it just sounded better is the best way to describe it. I had one sub set to 3 O'clock
position on the gain control but adding the second I had to lower them both to 2 O'Clock.

Just got my dual PB 2000's in!! I'll be able to keep the PB 1000's for 45 days thanks to Ed Mullen. biggrin.gif

So once I get them set up I'll post my thoughts.

The one box was damaged, but the sub made it unscathed.

That thing is huge! I bet it'll sound killer with 3 subs going.

I have a wedding this summer I need to save up for. Won't be seeing my 2nd sub until fall.

I actually have dual PB1000's so I'll have 4 PB x000's running all at once if I so choose for under 45 days wink.gif


Mooowwwaaaaaa!!!!!!!!

Again, just saying, not every peak is mastered to play at +105dB but the speaker system and subwoofer system should be geared toward clean, peak play.

Last night's movie was "U-571" and we listened at -15dB MVC. Sure full reference is nice but not everybody in the crowd can handle full reference.

Thanks for the clarification...smile.gif

Is that what I am hearing over here in the Town of Tonawanda??? smile.gif My wife says was that a small tremor? I said nah thats just nashou66 bringing SVS 4 online!!! biggrin.gif

Congrats man!
post #13404 of 15702
I'm curious how an SVS PB12 + or PB13 ultra can keep up with a FV15HP or XV15,VTF15H.. And how is it possible a 12 and 13" woofer can dig as deep as those subs mentioned?

TY eljr.. I'm at a loss. I can understand them being tighter,but not deeper...

Higher quality driver and amp.  Superb 13" driver and amp trumps a good 15".

post #13409 of 15702
I would say amp and driver design and box tuning.
post #13410 of 15702
Those are the responses I'm looking for.. TY.. Is it that the driver can take more of a pounding?
