BM165.1
The BM165.1 (6.5") is a critically doped HIPS cone unit developed for bass/midrange applications that require minimal colouration and low distortion over a wide frequency range. It uses a symmetrical field magnet system for large linear excursion capability with low distortion and mirrored double rear suspensions ensuring 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 optimum 2-way systems. The diecast aluminium chassis is vented below the suspensions to increase cooling airflow to the voice coil and magnet.
