Nice ported speakers built with Rega RS1 Drivers. 5 1/4" woofer and silk dome tweeter. Internal cabinet volume and port dimensions match those of the RS1, and the crossover is an upgrade of the RS1's. So I guess these are pseudo-clones of the original RS1. I got these speakers in a trade, and have no use for them, as they're too big for my desk system.
As for the sound, not quite as warm and full as the stock RS1 (which has a lossy cabinet). Mids and highs a little better because of the crossover upgrades. The cabinets are solid, to say the least.
