Wavecor SW275BD01 10 3/4″ die cast, composite cone subwoofers, 4Ohm
Overview:
10.75″ Ultra-High Performance Subwoofer Unit. When nothing but the most extreme in bass output and performance is required. Very low distortion from below 20 Hz.
Features:
- Extreme overhung voice coil with +/-16mm of linear stroke to ensure lowest distortion at very high drive levels
- FEA optimized suspension for improved symmetry and lower distortion
- Very large motor structure with 2.5” voice coil for better control and power handling
- Balanced Drive motor for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
- Venting through holes in cone neck for reduced distortion and compression
- Rigid Foamed Paper cone to ensure piston motion even at high levels – for reduced distortion
- Dual-spider design for higher mechanical durability and high-excursion stability
- Rigid die cast alu 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
- 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
