I bought a pair of the original Time Windows back in 1977. They were great paired with a Yamaha CA-800 integrated amp. The Time Frames came out a year or so later. The speakers in the link are not the original Time Frames. The original TFs were essentially 1/2 of a Time window with one woofer and one tweeter on a flat front baffle. OK sounding, but the TWs were way better.
I think the TWs listed for about $750 back in '77. They'd be quite pricier today.
How good these sound is anyone's guess, but I doubt they will sound like the original TFs.
