Hello Troels Gravesen, here’s an initial review of the SEAS-22 Thinwall. They’re powered by a Fezz Luna mini with 10W..... They sound absolutely relaxed yet still manage to convey emotion. At the same time, they’re very spacious and detailed... all with a sense of effortless ease. The bass is something special – it goes deep and feels just as natural. Absolutely brilliant!!! So far, it’s a test enclosure on test stands. But it’s definitely worth building some really nice enclosures; I’ll be starting on that soon. Before that, though, I’ll be testing various internal wiring configurations and capacitors.
