Hi,

Anyone have the Dual SVS PB-12 PLUS with the latest Sledge 800 watts amp?

If yes, how do they sound? Is there a huge difference between a single PB-12 PLUS or 2 PB-12 PLUS?

I am planning to buy another PB-12 PLUS but if having a dual subwoofers does not improve sound quality, I will probably not get another one.

Dual subs will smooth out the frequency response in the room and increase headroom. The quality of the sub will determine the SQ for the most part. The integration will also affect the SQ, so setup is very important. In short, 2 subs are better than one when setup correctly and the Bash or Sledge amp is not a major factor unless high levels of spl are generated leading to more distortion.

How do you like the single PB-12+ and what size room are you in?

Thanks for the information!

It is a very nice subwoofer but I think my room is large enough that I may want another one.

My room is 16 Feet wide and 27 Feet long with a 9 Feet ceiling. There are 4 open entry ways to other rooms or it is connected to other room. I think because there are 4 open entry ways that a second subwoofer will fill the room a lot better.

Adding a second matching subwoofer is never a bad idea. Your size room would really benefit from multiples.

Yeah that is a big room! Tell you what.. If your trying to just increase the spl you have now instead of smoothing out the sound for more seating (2-3dB gain) stack or put your next sub right next to the one you have now for a 6dB gain/headroom. Do you have a spl meter?

Thanks for your advice!

I will have to try that. Yes, I do have an spl meter.

In one of my past theaters (living room) I had things set-up to where the couch received the best sub response. Since it was generally just me watching a movie.. and the wife and kids could care less on family night.. I opted for the collocated option. When friends were over I gave them the best seating even though they would have been wowed regardless. Two will greatly increase your headroom and even give you a chance to play with the different tune options if your interested? The 12+ is a great SW, you’re not missing anything except maybe some headroom because of the size of your room imo. I have owned many SVS options and really liked them. I would be very interested in hearing back after your upgrade unless you have more to say or ask. cool.gif
