Before excuse me for my poor english.
A few weeks ago, I buy a beautiful pair of L300 in exellent cosmetic and technical condition. The speakers are in exellent condition too, the crossover is the same of the 4333 with the possiblity of bi amplification. I used them with a pre Mcintosh C22 vintage and for amplifier with a pair of OTL Reference by Silvaweld (100W per ch). My room is 16 X 16 feet, floor is made of wood.
My problem is that the bass are boomy and noisy, if I do anything on the preamp and with the button 'presence ans brillance", I heard only the bass speaker. I'm very disappointed because before I had Klipschorn and I do not have this problem. If speakers are a little bit raised, it is a very little better but the problem is the same. I don't know if I must sell them or try to find a solution. I need some help.
Thanks
