I use these speakers for many years. They are sufficiently linear and dynamic for a small home studio, a small sound system or a disco singer-guitarist or keyboard, for example, confrence, rptitions, returns. Versatile, so. 10-60 WRMS, 4 Ohms. But supporting a 100 or 150 W (4 ohms). They are a small volume and lack a little bass Obviously, but what comes out is clean trs. They are not suitable for the monitor or return bass, drums and piano. For vocals, guitars, sax, everything that does not sound in the bass I find them quite reliable. They are almost insensitive environment, on an equal microphone on the wall, ceiling, stuck on Tagrera, recessed, they are docile trs. Molded plastic body hyper-solid. I have no ide of the ratio Q / P, I do not even know if they are still distributed. If I had to sell mine (20 years, little girls!) I would suggest about 100.
