For the size of speaker I always felt the S120 had a reasonable amount of bass. However for really deep and powerful bass, you need the next step up, the M100 or MS150. I doubt anyone would ever say there was insufficient bass with them!

I am very surprised that the bass units don't have  foam rot though. Not sure I have seen a pair recently that don't! I always listen with a flat frequency response personally but as you have already said, different music and indeed ears prefer different settings.

Pleased to hear you like the MC120s!  

Well, there was still plenty of bass, but I still wanted to pump it up slightly. I think the sound is really excellent, though. I think the best indication of how good the speakers are is how they sound very, very loud, and very, very soft. The MC120.2s still have a very balanced sound at both ends.

There was actually foam rot, but the last owner replaced the foams. He took them to a very good repair place who did a great job... all the better for me! 

I have just properly installed my fully refurbished MC120.2's and have to say I don't find them lacking in bass at all - in fact quite the opposite! They are wall mounted on the original B&O brackets and this would no doubt show if there were any shortcomings with the bass as I believe mounting them on floor stands gives you the best low frequency enhancement.

I did replace the capacitors on the crossovers which made a noticable difference with the seperation and clarity so maybe this is something you may consider yourself.

I totally agree with Peter's comment re:- how well balanced they are.

Chris.

No lack of bass in my Beovox M150's for sure. Nearly 99% flat listning too.

They can handle the power of my BM8000 and sound is well balanced. Not a speaker you get tired off listning too.

I have read a Danish HIFI review of the Beovox MS150 and it says the same. Top points allround.

I hope to find a pair of Mc120.2 in white for my white Beosystem 6000 '80s.

I actually think it might be something to do with my amp. It has always made speakers sound like they were a bit lacking in the bass area. I got my MC120.2s and plugged them into my dad's high end 1982 Sony amp, and they sounded beautiful, and that was with a completely flat frequency response.

I think it might be a good idea to invest in a new amp. Anyone got any ideas? I think I want to get something new, rather than vintage.
