Hi, i'm a big fan of that line of speakers, i really like them... i work a lot with them to restore them...
most of the resonances is because they need a lot of work, first in the corrosver the caps should be changed and second all the damping materials are already de-gradated, i suggest to change the suspension of the mid-woofer and use a high quality damping material such a cork to reduce resonances.... is a lot of work and the suspension work requires an excellent job, any voice coil displace will end in mechanic distortions at high volume...
with the proper amp this speakers are sonus faber lumina killers, specially the SB-F3, better in every regard

hope there is no problem posting other forum, if i am violating any rule i will edit my post
Hi folks, the first thing you need to know is due to the full aluminum baffle, acoustic suspension technology on this speakers/monitors, the seals, as well as other components are completely ruined, so please if you already had a chance to listen to them don’t judge them if you haven’t listened...
