I have recently encountered extra boom from my Dynaudio DM 2/7 speakers having just upgraded my amp. The speakers sit 26 cm from the walls, and one of them is in a corner with 26cm to the rear wall and 30cm to the side (this is the boomiest of the speakers). I have resorted to placing the foam bung in the port of the speaker in the corner. This does effect sound quality slightly tho. Bass drum and other drums have lost that kick of air for example, which is necessary to replicate their sound correctly. Some people (from the forum) have kindly suggested things to do, such as using auralex foam pads for the speakers or granite slabs. I may well try these options but am thinking that my main area of boominess is from the air bouncing back off the walls.
I have just showed my flat mate and he seems to have come up with an ingenious idea of using foam like they do in studios, around the actual walls where the speakers are.
Does anybody know if this will work?
Thank you very much.
