I have my forever speakers (I think - Klipschorns) thanks to daves, but he alerted me to a new addition to the family that didn't compromise his wife's physique one bit.
IMF speakers are the brainchild of Bud Fries, and why he's acknowledged as a pioneer in transmission line enclosure technology became apparent when I visited Dave Saturday afternoon.
Listening to vintage soul of popular variety, we witnessed details that weren't readily available with conventional bass reflex designs. At once we got detailed, no-fatigue, well-defined highs and the bass that comes from the labyrinth of the design and the wooly stuffing placed ever-so-carefully within the enclosures, in proper proportion.
Adrian Walker, our string reference, is said to have commented that string bass was among the most accurate he's ever heard, compared to and with his extensive in-group experiences with the St. Louis Symphony.
For me, I felt one word summed up my experience. Effortless. Or, alternately, non-fatiguing, due to the time-coherent presentation we enjoyed from "some old speakers".
"Some old speakers"? I want "some old speakers" that do everything right, like "most new speakers" can't.
