Woofers

17 cm (6.5") High-End low midrange driver with stiff, anodized aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low electrical and mechanical losses due to vented pole plate, vented damper and capton voice-coil. Extremely long cone displacement due to long stroke voice coil. Suitable as low-midrange driver for 2-, 3- and 4-way high-end applications up to 2500 Hz.

20 cm (8") High-End woofer with stiff aluminium cone, solid aluminium die-cast basket and elastic rubber surround. Extremely low mechanical and electrical losses due to vented pole plate, vented damper and capton voice coil carrier. Fast pulse response due to light weight aluminium cone. Suitable for 2- and 3-way high end combinations and as low-midrange driver in 4-way high end systems.

20 cm (8") High-End woofer with black glass fibre cone, solid aluminium die-cast basket and elastic rubber surround. 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 long stroke voice-coil in conjunction with the extended rear pole plate, the vented damper, the vented magnet and the capton voice-coil carrier guarantees long strokes and highest power handling.   Possible connections: (1) one voice coil not connected (2) both voice coils in series (3) both voice coils in parallel  

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.

20 cm (8") High-end woofer specially for use as a small subwoofer. The extra-wide elastic cone, the long voice coil and particularly large magnet arrangement give this speaker extremely long excursion. Thanks to the multiple venting of the voice coil (pole piece hole, holes in the pole piece plate, cutouts in the aluminium diecast cone to vent the centring unit from behind) losses and flow noise are minimised. The capton voice coil carrier and the long voice coil enable the driver to withstand considerable loads. The diaphragm is a sandwich construction made up of layers of fibreglass and polyester fabric which makes it particularly rigid and low in resonance. These design features result in high level accuracy and excellent low-range bass imaging even in smaller cabinets.

25 cm (10") high-end woofer. The extra-wide elastic surround, the long voice coil and particularly large magnet arrangement give this speaker extremely long excursion. Thanks to the multiple venting of the voice coil (pole piece hole, holes in the pole piece plate, cutouts in the aluminium diecast basket to vent the spider from behind) losses and flow noise are minimised. The capton voice coil carrier and the long voice coil enable the driver to withstand considerable loads. The diaphragm is a sandwich construction made up of layers of fibreglass and polyester fabric which makes it particularly and low in resonance. These design features result in high level-accuracy and excellent low-range bass imaging.

30 cm (12") high-end woofer with a black cellulose diaphragm, large-format magnet arrangement and a massive aluminium diecast basket. Thanks to the multiple venting of the voice coil (pole piece hole, holes in the pole piece plate, cutouts in the aluminium diecast cone to vent the spider from behind) losses and flow noise are minimised. The combination of the voice coil carrier made of capton and the large 65 mm voice coil allow extremely high volume levels.

10 cm (4”) woofer with low resonant frequency and compact size. The wide and elastic rubber surround allows for a large excursion. A 2x4 Ohm dual voice coil allows 2, 4 and 8 Ohm operation, as well as stereo connection, for example via the rear channels of a car radio. The easy-to-install and visually appealing metal basket make the W 100 X a versatile subwoofer for hi-fi and industry. Possible connections: (1) one voice coil not connected (2) both voice coils in series (3) both voice coils in parallel.

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

15 cm (5.9”) woofer with robust polypropylene membrane. Powerful also in compact subwoofer applications.

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 the perfect game partner, especially when it comes to high robustness.
