Have you tried putting bass traps on the corners?
Hi Jjue,
I didn't try anything other than the keeping clothes under the bottom ports, however not blocking the air movement.
it does help to tame the bass boom, though can't eliminate to zero level.
I did hear mine MB2.5 with Avik-300, even with that I experienced the boom with all type of room treatment(in dealer,s setup), however to my surprise the MB3.5 had better sound than 2.5 in the bass and overall, maybe because the height of mb3.5 it could have the controlled the bass resonance better, by the way does it have the bottom port?

I'll try plugging foam into the bott port. That sounds like a logical approach and it's easy to do.

I plugged foam to the bottom port and it seemed to help. Bass is tighter and cleaner. I'll do more testing and keep you posted.

Murgeshj,

It sounds like your bass issue is more related to room acoustic and speaker placement. My 2.5's are about 9' apart(from the outter side). They are quite close to the side walls (less than 1.5'). 3.5' away from the back wall. Even without foam plugged to the port, I didnt have the boomy bass issue. Bass traps are still must have for me otherwise the mid and high are blurry (by using electrostat's standard). I havent heard Raidho's myself so I cant comment. But I can tell you the MB 2.5's soudstage and the darkness of the background are comparable to a few name brand speakers that I owned or auditioned before. I used to regret selling my Martin Logan and Maggie, but not anymore. I recently audioned some 10k plus speakers and I think 2.5's are still a strong contender in the space. I am not sure whether 2.5's are the right speakers for you or not. But I am sticking with them for now :)

I posted a video on YouTube to show how my MB-2.5's sound. I'm not good at A/V production so both video and audio quality are not too good. The audio quality is only a fraction of what it really sounds in the real world. The song is 'The Song My Mother Taught Me'.
