I'm in the market to upgrade my sub, and I'm considering either the SVS SB13-Ultra or two PB-1000's. Budget is up to the cost of a single SVS SB13-Ultra. Could always get a second SB13 in the future, of course!

I know that these two subs are quite different animals, with the PB-1000 being a ported design and the SB13-Ultra being sealed box. My receiver is a pioneer LX-85, front speakers are Castle Trent II's (bookshelves, 70Hz to 20Khz, nice flat EQ), center is a wharfedale pacific EVO II, surrounds are generic Aiwa's I requisitioned off an old all-in-one system.

The sub will be used about 50/50 for music/movies. My current room is only 40 cubic meters (~1400 cubic feet). Although we will be moving later this year, I'm pretty sure the audio room will be similar size, but almost certainly no larger than 2000 cubic feet. I usually listen at -15 to -20db (WRT to reference levels).

I'm leaning towards the SB13, as for not that much more money (relatively speaking) you get a sealed box design (for music) AND serious grunt – enough for all of my anticipated future needs (at least until I'd get a dedicated HT room, on the 10 year plan, in which case I could always add a second SB13 etc). I'm worried the PB-1000 may not be grunty or low enough if I should get a larger room, or not as musical as the SB13 i.e. not as "future-proof".

The SB12 may not be grunty enough in future (even with two of them) and the PB12's are getting too large in size for that all-important WAF.

Questions:

1) One SB13-ultra or two PB-1000's?

2) Can you have "too much sub"? In other words, if it's a smaller room, and not being 'cranked' hard enough, could subs lose range & accuracy? I guess the analogy would be driving a Ferrari to the supermarket to do groceries – it would splutter along in first gear, without "roaring". Would the SB13 play OK at lower volumes?

I can't audition either of these - no dealers anywhere nearby, and I'm not sure SVS's agent here in NZ has the same "try in your own home" return/upgrade policy - but I will email them these questions and see what they say!

2) No problem. You just won't use the extra headroom on the sub. It will work fine.
1) It sounds like dual SB12-NSDs could also be OK for your. See Audioholics review of the SB12-NSD where they write,
Quote:
The SVS SB12-NSD receives the Audioholics Bassaholic Medium Room rating, which means that this sub is recommended as maintaining adequate headroom in rooms or spaces of between 1,500 to 3,000 cubic feet and/or for users who usually listen at moderate volume levels.
Although I think you might need more from the low end below 25hz than what the SB12s can provide.

...or two SB12's (still less price than a single SB13, but they lack parametric EQ, which would be handy, since my receiver doesn't have Audysee or other base EQ - just MCCAC).

Also not sure if the SB12-NSD would have more movie "grunt" than a PB-1000. Sure it's larger and got a bigger amp, but it's not ported. From the graphs it looks louder / just as deep.

[EDIT: Thanks for your reply above - seems like the 12's don't quite get as low as the SB13 or PB-1000's looking at SVS's website - although in-room mileage may vary, of course.]

Leaning towards 2 x PB-1000's now.

I'd get 2 PC12-NSDs. They don't take up much floor space. A pair will get you down to 18hz with more output than a single SB13.

You can't smooth room modes with only one sub.

OK - after thinking more on it, I'm now going to go for a single SB13-Ultra. Will post my feedback in the appropriate owners' thread in due course smile.gif

I don't think you'll be disappointed. The SB13-Ultra is one of the best subs made.

Thanks. As noted in my edited first post, there's always the future opportunity to add another sb13 to smooth the room.
