10 cm (4") woofer with low resonant frequency and compact size. Large strokes possible due to elastic rubber surround and deep magnet while noise is minimized through venting of air gap and t-yoke. Simple basket for various installation possibilities.

13 cm (5") woofer with robust polypropylene membrane for very compact subwoofer. Designed for multi-purpose applications due to 2 x 4 ohms double voice-coil, with excellent properties as 8 ohms drivers in series configuration. The enormous membrane displacement for its size as well as the very low resonance frequency allows a considerable sound pressure level, the one does not trust such a small speaker.

Possible connections:

(1) one voice coil not connected

(2) both voice coils in series

(3) both voice coils in parallel

16.5 cm (6.5 ") woofer with black glass fibre cone, metal basket and robust rubber surround. Thanks to a perfected selection of materials and adhesives, the loudspeaker can also be used under extreme environmental conditions, like in extreme heat or coldness and provide the necessary bass foundation.
The computer-optimized suspension geometry, focused on a very high excursion but a small installation space at the same time, allows enormous sound pressure levels without fear of a sudden limitation. This makes the W 165 A - 2 Ohm the perfect game partner, especially when it comes to high robustness.
