Description
Product Details

Wavecor SW280WA01 11" Shallow Glass Fiber sub

11” High Performance Low Profile Subwoofer Unit.
Innovative design with dual rubber surround suspension and flat sandwich cone.
Recommended for high end audio applications, where build-in depth is limited.
A typical application is for high performance in-wall systems

FEATURES

Dual surround suspension and flat cone design to minimize build-in depth
Glass fiber / PMI foam sandwich cone to maximize bending stiffness leading to improved freqiuency response
Innovative dual cone design to allow magnet mounting “inside” the cone resulting in reduced overall depth
Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
Rigid die cast 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 vented 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
Gold plated terminals to ensure long-term trouble free connection
Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
