The Technics SB-M10000 introduced in 1995 is a 4-Way 12-Speaker limited series loudspeaker system. The SB-M10000 used Dual Dynamic Drives (D.D.D.) that achieved flat response down to super-low frequencies. By developing a Kelton speaker system that alone is capable of the advantages of both sealed speakers and bass-reflex speakers, the SB-M10000 achieved ample frequency response reaching down to deep bass. The speaker was capable of easily reproducing deep bass with a sense of natural and magnificent scale as if floating. The speaker included four passive radiators with 27-cm cones for the low frequencies and four 22-cm cone woofers for driving. Unique push-pull edges reduced distortion by equalizing the amount of air displacement back and forth when amplitude occurs. The speaker included two 18-cm mid-low units using composite mica diaphragms for the lower midrange frequencies, a 6-cm pure-mica oval dome diaphragm unit for the upper midrange frequencies, and a 2.5-cm super graphite dome tweeter for the high frequencies. Given a multi-layer glossy veneer finish limiting diffraction reflection, the cabinet produced a tallboy form increasing the sound imaging in the space. The original sale price was 90.000 DM for a pair. According to some (yet unverified) sources there were only 8 pairs made.
