I've applied a KISS-alike mod except instead of Creatology+Dynamat Extreme combo I used thick layer of BASF Comply foam. (In form of Comply wraps.) The chunks on the sides were left as is mostly, with a slightly increased thickness of the hard foam layers. Interestingly enough, the use of this kind of silicone foam is much more effective on the magnet and nearby surrounds than creatology + dynamat extreme. It's slightly smoother sound yet as a result of additional highs peaks absorption. Not a huge difference but I'd take anything. I did not cover the magnet hole with foam, only the whole magnet and unvented plastics on its sides. The extra thick creatology-like foam layer improves bass handling a bit still too. Main problem is that this foam is expensive if bought as Comply Wraps. I think it is BASF BISCO BF-1000 foam, can someone find a reasonable retail source for this?
