Scansonic mb serie

My 2.5 have approx. 400 hours on them and yes they sounded like crap when I first set them up.Everything is true about setup from above..9 feet apart for sure.I found to control the bass a sub was necessary in my room as well as bass traps in corners and wall panels front and rear.Ive tried both tube and solid state.With SS in my room it sounds way too sterile which is basically how my Raidhos sounded,with tubes the ribbons are tamed a bit and the mids are fleshed out more with better imaging.Overall I actually like these better than the 42k Raidho C3 I had,simply from the money spent if nothing else.

Still the Mb2.5 have the bass boom after 90 hrs, and I have limitations of space to place them 9feet apart.
And unfortunately I ditched my beloved Totem model 1.
Hopefully get better and MB2.5 are not as reveling as Model 1.
Using with Spec amplification, had driven the totem comfortably and delear confirmed that spec comfortably the PMC's Fact series..

I'll wait for my local dealer to get them

Have you tried putting bass traps on the corners? I dont think mine has 90 hrs yet but the muddy bass issue was gone after 40 or 50 hrs with bass traps. I am not familiar with your Spec amp so cant comment. Alan mentioned using Hegel H80 and I guess why I am getting good result with my H200. I am still breaking in mine 2.5's but it has become a quite enjoyable process for me.

Jjue - For grins and giggles have you tried removing the bass traps now that you have about 100 hrs on them? Although you may want to wait until you hit 150hs. I think Missioncoonery mentioned a drop in SQ when they hit 125 hrs. With my D2's the bass went crazy at 525 hrs and lasted for about 10 hrs. But remember the diamond series is a completely different driver - crossover and cabinet.
