You might want to contact Martin Logan on this as well as Mike VanEvers. I find them (ML) to be very helpful. If you are trying to get rid of the slight edge you described with these tweaks, I don't think you'll be successful. What you are hearing is your solid state amp driving the panels. If these are independent tweaks, another story. I've actually used the TeknaSonic C-10's and C12's on a poorly dampened ribbon hybrid speaker enclosure and they made a slight difference (2 on each enclosure). I'm not sure how they would work on the Request enclosure. Sorry, but I don't think this will work very well with your speaker. ML hybrids have a challenge in intergating the woofer and the panel, but I don't think there are any inherent problems with the enclosure. Audition a good tube amp first, and go from there. I'd be very, very careful about adding PC's that filter to your speakers. Don't know about more RFI/EMI, never had any problems. Good luck.
