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 :smile:

    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.

    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 Barrier

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

    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.
