Should be getting my bonus check on the 13th. I will be purchasing the final pieces for my home theater, one of which is subwoofers. Through this site I have found that bang for my buck SVS seems the way to go. My problem comes with which model. My room is 11 x 21 x 7'6" and will be for 100% movies.


Option 1

2 x pb2000


Option 2

1 x pb13 ultra


In my country the new pb2000 are priced to reflect our current weak dollar where the pb13 ultra is still priced good being stock from when the dollar was higher. It is a private two seat theater and I was wondering if I would be better served with the ultra as I could place it to suit the primary listening position. I don't' have to worry the same as someone who is trying to get perfect bass at many listening positions or rows.


There is a only a $200 price difference when shipping and tax is added in. Before anybody says buy the ultra and add another one later I have to move on to the bathroom reno next as part of the deal for doing the theater so there won't be any money for quite sometime. Just looking for that room shaking chest crushing movie experience.


Thanks


Jason


Edit: Rythmic and HSU were options but shipping put them out of my budget I set. SVS has a distributor in my country making it an easy purchase.

Well ive done a ton of reading the last week myself and settled on a single pc13 ultra which is nearly the same as the pb. Hasnt arrived yet to give u a reeview but it sounds like its going to blow me away. My room is 22x17. The general consenssus is 2 is better for multple listening positions. Since u have one sweetspot like me i would consider one large sub. Im sure the pros will chime in but thats my 3 cents.

I'd go for the PB Ultra (or the PC to save a few $$ and for easier placement) for sure in your situation. I have only the one sub and by my ear "measurements" I get nice bass across a four person sofa in my smallish (1650^3) room.

I would go with dual subs of what ever fits your budget. If you can get a ultra now with the option to add another later then go that route. If not go dual PB-2000's.

That doesn't make a lot of sense based on what the OP stated about having only one primary LP. By going with a pair of PB2000s he would be giving up output and extension. If he can place one big sub where it works for his LP then that would seem to be a better choice.

Dual PB-2000's could very well end up having more headroom then a Ultra depending on how much eq is applied to flatten the response. Just because the Ultra has a Flat native and peak response does not mean that is how the sub will respond when placed in room. 1 seating position or 12 it does not matter, a single sub can not effictively smooth any room modes.

I think I would probably go with two subs.

Thanks for the posts. I did enough reading to sway me towards two especially if I ever move. I ordered the pb2000 unfortunately they only had one left in stock so I will have to wait for the second. Give me time to play though and see if I even need a second.

The PB13 Ultra is such a vastly superior sub, I would definitely grab it before dual PB2000's.  You would have more overall output than dual PB2000's, lower extension, tuneability, piano finish, etc etc etc.

 

Basically, its the best quality, highest output ID sub made vs two decent $800 subs.

 

Woops, just saw you ordered a PB2000.  Is it too late to change your mind?

I knew the Ultra was the better sub but after reading about the pb2000 and the benefit of 2 subs I should be more than happy. I can live with my decision. I'll have to wait for the second to be back in stock so In the mean time I ordered an oppo player to replace my cheap lg one. If for some reason Iam not happy I can always return or swap it out.

you made the right choice...dual subs is fantastic...it is more enveloping even in the one seat you are concerned with...congrats!

 

[bear123]


I am sure 2 PB2000's will rock you in your small room...I have one in my 2525 cu. ft. room and very happy with it.

actually dual PB2000's would almost match the output of a PB13Ultra. Look at the NSD numbers on data-bass and add roughly 8.5db. 2.5 db for the performance increase between the NSD & 2000 then another 6db adding a second.

It's my understanding that you only get the 6db gain if the subs are co-located, otherwise it's more like 3db.


I know the OP made his decision but I'm betting it's the wrong one. The Ultra is SO much more sub for only $200 more than a pair of PB2000s it's not funny.


Extension, output at 20hz and below, lack of distortion, sound quality, build etc.... no contest.

Does anyone know the dimensions and weight of the two subwoofers being discussed?

Dual subs adds 6 dB output regardless of placement.  Mutually coupled, dual subs will give a somewhat static 6 dB increase matching the FR of the single sub, but obviously not smoothing in room response.  Spread out in various corners of the room to maximize the smoothing of in room response, the average increase will still be 6 db.  Likely, the increase will be more than 6 dB in a valley, less than six in a peak of the single subs in room response, but 6 dB overall.  There will obviously be some differences due to placement and room gain that can cause the increase to be more or less than 6 dB.

Actually they would have to be with 1/4 wavelength of each other for that to be accurate.

Not trying to argue but doubling displacement while maintaining the same voltage swing adds 6db regardless. Depending on placement can dictate what frequencies at the LP that the full 6db will be present.

From what I understand, this is a common misconception on these forums.  Mutually coupled, or within 1/4 wavelength of each other, will not change the in room frequency response, hence the flat 6 dB increase matching the single subs response.  But dual subs = 6 dB average, whether coupled or not.

I'm open to listening. Can you provide some links or information to support this?
