I'm sorry I haven't posted more of late, but..I'm addicted to facebook now. Heh.
What I have just purchased, will blow you all away!
They're called "port chuffer cool-its". I found them on line, at an audiophile site. Since I have M60s...I ordered the "triple threat combo pack". There are (3) turbo-prop electric "fans" that bolt on the the speakers (1) on the front, and (2) on the back.
They actually suck the sound right out of the cabinets, not only cancelling out any possible chuffing....but increasing bass response x 2! I really like them, and I think other Axiomites will too. The "fans" spin so fast, they are silent, and are almost invisible! (grille cloths stay off now) Anyway, decide for yourselves, if "port chuffer cool-its" are for you.....here's the web site to check out. I got mine(all six) for only $1,100.00!!
