CSS LDW7 - 7" Midwoofer

The LDW7 is a formidable woofer that easily competes with woofers costing 2-3 times more. It's low distortion let's you hear all the details in your music while its specifications give it deep bass in a modest cabinet with plenty of linear throw to pump out music even at higher volumes.

FEATURES

• Symmetrical motor structure for optimal drive force balance with built-in aluminum field-stabilizing ring reduces even order harmonic distortion
• Centre pole copper cap reduces voice coil inductance and minimizes variations in inductance relative to voice coil position
• New paper/fiberglass cone with improved consistency and stability
• Die cast well vented aluminum basket reduces air flow speed and audible distortion
• Vented voice coil former reduces distortion and compression
• Vented dual flared center pole reduces noise at large cone excursion
• Heavy-duty black fiber glass voice coil former reduces mechanical losses resulting in better dynamic performance and low-level detail
• Large diameter 1½” voice coil permits better control and power handling
• Low-loss suspension (high Qm) allows better reproduction of details and dynamics
• Conex spider provides better durability under extreme conditions
• Gold plated terminals ensure long-term trouble free connection
• 80W RMS, 200W Peak
