Hello,Every one. How are you doing? This time I am introducing clear sound speakers. Nihonbashi shop Kenji Masuzawa. This is a pair of QUAD ESL 63 Pro. It released 1935 in the U.K. QUAD means quality unit amplifier domestic. ESL model has released in 1957. Next model ESL 63Pro has released in 1986.
It has taked for 10 years more to plan this model.
ESL 63Pro mounts electrodes in a concentric circle line. Limiter prevent to be broken caused electrostatic sparks.
Its sound is really natural. I think that it because of spherical surface waves.
Condenser speaker sound is clear and delicate. But it need to charge before sounding. Please try it.
