I don't know how many of you are familiar with KLH six or seventeen's, but they are unique. They sound good, very good. They may not boast the best audiophile terminology for descriptions, but you can listen to them indefinitely. They have bass, surprising bass, tube like midrange, and adjustable highs. I've heard they were one of the east vs. west coast defining speakers at a time. Granted they are actually sold old they sort of pre-date a lot of audiophile mentality.
But can we recreate those sounds today? Are there drivers out there like them? The only thing sorta close I've never heard, but assume, is some Klipsch units for churches and what not (massive, the size of a podium, horns). I don't know if they are sweet, but have flavor.
