I have them on my speakers. They have a self-adhesive on a big flat magnet and the baffles attach to the magnet. I haven't noticed any marring and I've taken them off reapplied them to my speakers several times. These are more effective on underdamped speaker cabinets. I am not familiar with your speakers so I can't comment furthur on their efficacy.
Has anyone tried Tekna Sonics on floorstanders?
These vibration absorbing devices have been around for quite awhile and I was wondering if anyone has had any personal experience with them? I have large floor standing speakers (Silverline Sonata 2's) and it seems like they would be ideal candidates for them... I hesitate to try mostly because I worry about attaching them to the speaker... are they glued? Will it mar the finish? and are they effective? The Sonatas have 2 x 10" bass drivers (ported to the back) as well as the midrange and hi frequency drivers above. Any ideas / suggestions? I'm driving them with VTL Mb-125 monoblocs with a Sonic Frontiers Line 3. Lots of jazz, chamber music, and simple vocals.
