More Power or use subwoofer to boost bass for music

Thanks George.   Thanks for the information on Parasound A31.   That is good to know.   Maybe I do need more power to drive those B&W.   I'll checkout the review.

Also, many thanks to others for information on room treatment and multiple subwoofers.    One thing I should have mentioned in my original post, is that I live in an apartment, not small, but average size.  I don't have a lot of options to accommodate multiple subwoofers.   I actually do have a subwoofer now.  It's a very old Def Tech subwoofer from the 90's.   It doesn't have a whole lot of connection options.   I only use it for movies.  I was looking to replace that anyway.   

I do like the option of adding some acoustic panels, and will look into that further.

Thanks!

xcool OP Just found proper test on the A31 as I thought not much current ability into low impedances. The 4ohm wattage should be a lot higher, and they didn’t do the 2ohm as it would have been trouble (bang maybe). Not the amp for these speakers.

 Cheers George

What amp did the dealer use ??????

dual subs; as large and powerful as you can fit and afford. I like the big HSU Research units

i don't remember what the dealer use.  It was actually in Magnolia shop of Best Buy when I heard them for the first time.  I think they might just be using a Rotel integrated.
