Wavecor SW182BD02

Wavecor SW182BD02 7" die cast, alu-cone subwoofer 8 Ohm

The 7” transducers SW182BD01 (4 ohm) and SW182BD02 (8 ohm) were designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities.

Features

• Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
• Extremely large linear stroke, Xmax = ± 8 mm, ensuring low distortion at high output levels
• Very rigid black aluminium cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
• Rigid die cast alu chassis with extensive venting for lower air flow speed reducing audible distortion
• Vented voice coil former for reduced distortion and compression
• Vented center pole with dual flares for reduced noise level at large cone excursions
• Heavy-duty black fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
• Large motor with 1½” voice coil diameter 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 cone and 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
