Hi,


I am building a home theatre with 9 Atlantic technology 2200 speakers.


I am looking at both of the following SVS subwoofers but am worried that the PB-12 plus might "overpower" the rest of speakers.


1. PB-2000

2. PB12-plus


What do you guys say?


Thanks

Sub won't "overpower" your speakers as calibration levels will be the same, however if you can afford it, and you have a larger room, I'd get for the PB12 Plus..or even the Ultra. Or two. Or four.


Even if you bought eight PB Ultra 13's, the dB level during calibration would be exactly the same as a SB1000.

As indicated by fatbottom, if you calibrate your system, your sub should complement, not overpower, your speakers.

How big is your room (l x w x h; sealed, or open to other spaces)? What is your budget for sub(s)?


A single PB-2000 might suffice, or you might need dual PB12-Pluses to get sufficiently satisfying bass.

Room is 15 W*22L*9h.


What do you mean by calibrating subwoofer.


I can afford both but if i can save up money why not.

Calibration either involves auto setup from your AV amplifier, or doing it manually with a dB meter.

But with the speakers I have wouldn't pb12 be overkill.


As when level matched, pb12 would always be underperforming due to limited capability of speakers?

Nothing to do with your speakers, it's your room size, that's a big room

Hi,


Can somebody tell me how to understand subwoofer specification.


For speakers we have sensitivities hence we can calculate what is the maximum loudness at which the speaker can operate.


Is there anything similiar for subwoofer.

Not really no. Unless you buy a passive subwoofer, but even then it won't give out sensivity, just amplifier requirements.


With a active sub they give


Dimensions

Driver size

Subwoofer type- ported, sealed, radiator

Amplifier power

Frequency response

Doesn't CEA2010 testing give you an idea of how loud a subwoofer can get without distortion.


I have come with following numbers and would appreciate if someone can correct or endorse me.


My atlantic technology speakers are rated at 90 sensitivity. My integra 70.4 shall approximately provid 80watts per channel. My central seat of home theatre is locate at approximately 8.5 feet from all seven speakers. Using the the following calculator, I get that the sound pressure level at my central seat shall be approximately 109.2 DB. This is way above reference level comfortably.

http://myhometheater.homestead.com/splcalculator.html


CEA2010 results for SVS-Pb2000 at 1m are 116 and 119 db whereas the corresponding pb12 plus is approximately 2 db louder accross all frequency.


So the PB2000 shall be 112.25 & 115.25 whereas as for pb12plus it shall be 114.25 and 117.25 at my listening position.


So theoretically pb2000 shall produce reference level sound at my listening position comfortably due to reflections from walls etc.


So why opt for the bigger subwoofer.

When I bought my subs I never looked dB output. When buying a sub


a) Budget

b) Size of room

c) Single or dual

d) Preference for sealed or ported

e) Size requirement of the sub

f) Connectivity and other features.

g) What it's going to be used for - home cinema or music, or both

If you have to ask that question, a big powerful badass sub probably isn't worth the money.

Ok so here is what I would do.... If you have the budget for a PB12+ but are wondering if you can get away with a PB2000: the PB12+ is $1,399 shipped the PB2000 is $799 shipped. I would opt for 2 PB2000's for $1,499 shipped. Dual PB2000's are ONLY $100 more than a single PB12+.

Very true.

 

But the PC12-Plus is $1,199. 


 

Doesn't that throw a wrench in the works, eh?

 

I think that of those choices the dual PB-2000 would probably be the most popular.

Agreed. Dual PB-2000s would be the way to go!
