Wavecor SW215WA01 8-1/2″ Balanced Drive Paper Cone Subwoofer 4 Ohm
Overview:
The Wavecor SW215WA01 is an 8-1/2″ paper cone subwoofer that was designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities. The SW215WA01 utilizes balanced drive motor technology for dramatically reduced distortion.
Highlights:
- Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
- Large linear stroke, ensuring low distortion at high output levels
- Rigid air-dried paper cone to ensure piston motion even at high levels – for reduced distortion
- Rigid steel chassis with extensive venting for lower air flow speed reducing audible distortion
- Vented center pole with dual flares for reduced noise level at large cone excursions
- Heavy-duty fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
- Large motor structure for better control and power handling
- Built-in alu field-stabilizing ring for reduced distortion at high levels
- Low-loss suspension (high Qm) for better reproduction of details and dynamics
- Black plated motor parts for better heat transfer to the surrounding air
- Conex spider for better durability under extreme conditions
- Gold plated terminals to ensure long-term trouble free connection
- Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
Product Description:
The Wavecor SW215WA01 is an 8-1/2″ paper cone subwoofer that is equally at home in a home theater or hi-fi installation. This driver utilizes a rigid air-dried paper cone that is also designed to reduce distortion. The aluminum field-stabilizing rings and balance drive technology also aid in distortion reduction. The SW215BD01 offers extremely low mechanical losses which allows for great performance in low volume or extreme dynamic situations.
The SW215WA01 is ideal in 2 or 3-way designs when being used as a woofer or a low frequency driver. With the attached foam gasket, this driver is easily mounted in several different methods.
