Is anyone familiar with TDL Compact speakers?

a descendant of imf, the tdl line was very good. a transmission line design, that is not unlike pmc.

Well, I had listened to a pair of small stand-mounted TDLs many years ago -- so yours may not be the same pedigree speaker.
Have you listened to LS3/5A? If so, the TDL are slightly more bloated in their bottom (~90Hz) & the upper mids. They provide a better sense of volume than the bbc & some more extension at both ends of their freq response. IIRC, those TDLs were back ported.

OTOH, I really don't remember what amp we used on them. I had two tubes & one ss back then (I also had a pair of Rodgers ls3/5a -- hence the comparison).

BTW, Marty, if you're being "offered" these speakers, wouldn't it be impolite to do anything else but accept???
