The Unison Research MAX 2 model is designed to be matched, in particular, to the Unison Research valve amplifiers. For this purpose, not only the sensitivity but also the impedance were optimized. The MAX 2 is a two-way floor standing, reflex-loaded system, of important size however compact. The reflex ducts are front-firing to make easier to place the diffusers in the room. This speaker can also be used as front channel in home theater systems. With two pairs front and rear, you get a high- impact home theater system that does not require a center channel or sub-woofer.
