Very good sounding speaker set. It’s still original and beautiful looking. Read the positive online reviews about the sound. After many years of evolutionary refinements the most advanced version of the Mission 770 drive unit is now designed into our new model 737 Renaissance. The cone membrane for this model offers a unique combination of rigidity, lightness and acoustic opaqueness. The drive unit is manufactured into an esoteric die-cast magnesium chassis to improve rigid coupling. The acoustic properties of the cone are such that they do not allow for internal reflection and standing waves to come out of the cabinet and reach the listener out of phase. Furthermore, a solid block of Mission acoustic foam is built into the inside of the cabinet to attenuate such standing waves. The Renaissance cabinet is of precision multi-folded construction, visco-elastically damped and incorporates our special MDF baffle board. The total system is reflexed using the Mission resistive port and resulting in extended low frequency and power handling performance. The Renaissance now possesses many attributes of its predecessor but at substantially lower cost. For this model, as well as the 770 Freedom and the 780 Argonaut, special Mission stands are available which lock into the loudspeaker and are offered as an optional extra. The Renaissance is recommended for use with amplifiers ranging from 30W to 120W per channel.
