BM165.1 (6.5″)

The BM165.1 (6.5") is a critically doped plastic HIPS cone drive unit, developed for bass/mid applications that require minimal colouration and low distortion over a wide frequency range. It uses a symmetrical field magnet system with an extended pole piece for large linear excursion capability, along with mirrored double rear suspensions that guarantee transient stability at high drive levels. The Thiele-Small parameters are optimised for relatively small enclosures to give a bass performance that complements the extended midband enabling excellent 2-way systems. The diecast aluminium chassis is vented below the suspensions to increase cooling airflow to the voice coil.
