Scansonic mb serie

I've always said they sound higher than their price point. The only real downside is placement. If you get that right they will sound fantastic. Get it wrong and they will sound OK. But as far as driving them it shouldn't be too hard. On another forum a couple of folks are driving theirs with 7 - 15W tube amps and say they love it.

Another thing you may want to try is plugging the bottom ports with cloth or foam.

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 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 :)
