Audio Electronics BMB180 6.5" Bass / Mid Speaker

Handbuilt in England, superbly engineered high end drive unit.

Audio Electronics Ltd were a small English company that made various top quality bespoke bass speakers for Heybrook (Sextet), BMW cars, & the flagship JPW Ruby range.

These drivers feature a top quality diecast alloy chassis, loaded polypropylene cone, long throw suspension, butyl rubber surround, 34mm high temperature voice coil with kapton former & ventilated pole piece.

Highish Qms usually dictates an open midrange & that is definitely the case here; midrange is well controlled meaning simple 2nd order crossovers around 2.5 - 3khz are a viable option.

These sound beautiful in a transmission line enclosure with wonderfully solid bass & an open, revealing soundstage.

These units are incredibly rare & are the only ones left anywhere ~ plenty in stock, we hold the archive.

Can be used as a replacement for the (red) spun alloy coned BMR180 found in the flagship JPW Ruby 2 & 4.
