What do you fine folks recommend to dampen behind the drivers....I have read posts where people prefer both. Also where is a good place to purchase or "shot in the dark" anyone have some left over for a price of course

Also, it seems that less is more with this stuff...I am looking to just put two 4"x8" strips behind the drivers only. After reading a few posts that seems like the "optimal" placement.Polk SDA 1C Upgraded, Eastern Electric Minimax Supreme DAC, Parasound HCA 1200ii, Belles 21a Preamp, Rotel RSX-1056, Matricom G Box Q, Blue Jean & Signal Cable interconnects, Sonographe SG-3 TT, Panamax M4300-PM

Yes, strips only behind the mid-woofers.
I used No-Rez, which comes in three thicknesses I believe, I used the thickest. A lot seem to favor BlackHole 5 I think but I can't speak to discernable differences, it's a bit more expensive.

Sonic Barrier is also good, and a lot less than BH5.

Now I read some negative posts on Sonic Barrier and it seemed BH5 and No-Rez were superior even though the price is definitely right with the Sonic BarrierPolk SDA 1C Upgraded, Eastern Electric Minimax Supreme DAC, Parasound HCA 1200ii, Belles 21a Preamp, Rotel RSX-1056, Matricom G Box Q, Blue Jean & Signal Cable interconnects, Sonographe SG-3 TT, Panamax M4300-PM

I've used all three. BH5 is the best, followed by SB, then NR. Just my own opinion/experience.Home Theater/2 Channel:

I used Black Hole -5 on my 2Bs and the change in the cabinet was so dramatic I wasn't sure if I liked it or not. I left it in and got used to the sound. I believe I have one sheet and scraps enough to do a pair of speakers. I never tried any other sound deadening materials but I will say BH-5 works as advertised. P/M me if interested and maybe your near Jersey somewhere.2chl- Adcom GFA- 555-Onkyo P-3150v pre/amp- JVC-QL-A200 tt- Denon 1940 ci cdp- Adcom GFS-6 -Modded '87 SDA 2Bs - Dynamat Ext.- BH-5- X-Overs VR-3, RDO-194 tweeters, Larry's Rings, Speakon/Neutrik I/C- Cherry stain tops Advent Maestros,Ohm model E
