SW178WA01 is a woofer designed for dedicated subwoofer applications. It works equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups. The extremely stiff aluminium cone, the long linear throw, exaggerated ventilation, and the special dynamic linearization short circuiting ring together makes up for an unusually linear and low-distortion woofer. Even at very high signal levels, the unit behaves controlled and without distortion. Due to very low mechanical losses SW178WA01 masters equally well low level details and dynamic requirements.
Features
Very rigid aluminium cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
Vented voice coil former for reduced distortion and compression
Vented center pole with dual flares for reduced noise level at large cone excursions
Vented chassis for lower air flow speed reducing audible distortion
Heavy-duty black fiber glass voice coil bobbin to reduce mechanical losses resulting in better dynamic performance and low-level details
Large motor system with 1½” voice coil diameter and 110mm magnet for better control and efficiency
Built-in alu field-stabilizing ring for reduced high-level distortion
Long linear stroke motor for reduced distortion at high levels
Linear suspension with specially designed CONEX damper (spider) for long durability under extreme operating conditions
4-layer voice coil for increased control and better small-cabinet performance
Gold plated terminals to prevent oxidation for long-term reliable connection
Sealing gasket pre-attached for hassle-free mounting and secure cabinet sealing
