Wavecor SW182BD04 7″ die cast, alu-cone subwoofers, 8ohm

Overview:

The 7” transducers SW182BD04 (8 ohm) was designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities. The pair was developed as an alternative to the previous designs SW182BD01 and SW182BD02 as a preferred choice in many typical applications because of optimized suspension, lower moving mass, and lower voice coil induction.

Features:

• Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
• Extremely large linear stroke, Xmax = +/-7 mm, ensuring low distortion at high output levels
• Optimized suspension for improved symmetry and matching of Force(x) curve
• 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 1.5” 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
