Foam Plugs

[Stoney]

I have read about foam plugs that B&W includes with some speakers to plug into the ports to reduce bass output. I have a pair of DM 605 S2 and I was wondering if I could use plugs to reduce some boomyness in my room. What are the plugs made of? Is the foam similar to the foam used in the swimming pool "noodle" floats? Would I get the same effect by tweaking with the level and EQ settings of the sub amps? (see attachment)

Hello Stoney, you could use the foam from those noodles to plug up the ports, it will tighten the bass up and help control some of the unruly bass. You may try setting the EQ curve for the flattest response provided, and go from there. Also how close are your speakers to the back wall?

i had pair of 604s2 once and found that the base was cleaner after i plugged, b&w used to provide two types of foam, a dense foam and a more spongy foam with larger locules, in theory to have less of plugging effect, the spongier foam seemed silly to me, kind of like straddling the fence

if you lost your foam plugs, there isn't anything special about the ones b&w provides, any dense foam will do

Thank you for the replys.
Robert;
I posted a thread here: http://www.htguide.com/forum/showthread.php4?t=18281
with this and some other questions that include my set up and room dimensions. The driver faces are about 20" from the front wall (too close) but I am thinking that moving them further enough out to make much of a differance would be difficult.
