I own a pair of Shearwater Hot Rods, marvelous speakers using Sanspeak drivers in a 1/4 wave transmission line enclosure. 2" thick baffle, 1" side walls, audiophile internal wiring. Extended range, detailed, delightfully sweet, a little on the polite side.
I've been following the new Meadowlark Audio for some years now. After some number of years in other fields Pat found that he could build speakers without compromise using new tech, instead of the best speakers at a certain price point he could build the best speakers period, fully active, no passive crossovers. He was building a couple designs on consignment, looks like he's expanding. All the best to Pat and his company, he was one of the true innovators in our hobby, he's been building speakers since he was a kid.
