B&W Matrix802 Series3(M802S3)
¥ 330,000 (1 unit, released in 1992)
Commentary
A floor speaker system that shares almost all of the latest technology used in the Matrix801 Series3.
The Matrix802 Series3 requires just half of the 801 footprint.
Two 20 cm cone type woofers made of polymer cone are installed in the lower range.
The mid-range is equipped with a 12.6 cm cone type mid-range.
The diaphragm uses a Kevlar cone. This diaphragm uses a special woven pattern with Kevlar directivity to cause resonance cancellation on the cone surface, and realizes a natural reproduction sound with less harsh resonance.
A 2.6 cm dome-shaped tweeter is installed in the high range.
This unit uses a special fluid metal with low viscosity to dump specific resonance points to increase high-frequency playback capability and improve power handling, eliminating the need for APOC protection and the influence of relay circuitry.
The network section uses an inductor with pure iron particles as a core to achieve lower distortion and higher resolution. This inductor has a much higher saturation point than conventional ferrite inductors. The location of the inductor is adjusted to minimize crosstalk.
In addition, the cross-over board is divided between low frequency and middle / high frequency to eliminate mutual interference.
The enclosure uses a bass reflex system.
The interior uses a matrix cabinet structure to eliminate cabinet resonance and coloration from the woofer cabinet, and the mid-range driver section uses a special fiber enclosure to eliminate resonance.
There were two variations of exterior finish : walnut and black ash.
