P4000-12

Dual 2 Ohms
4000 Watts
Power Handling = 4000 Watts peak; 2000 Watts RMS each
Frequency Response = 25-700 cycles

Features

High-strength 12” aluminum-cast basket with venting to allow cooler operating temperatures and lower air pressure under spider
Double foam, heavy-duty aluminum cone for low distortion at high volume
256 oz high-energy magnet for efficiency and high output
8 ” vented and extended T-YOKE to prevent damage to voice coil, relieve pressure under dust cap, and enable speaker to run at cooler temperatures
Extended pole piece to enhance magnetic field linearity
Long-throw 4” dual 2 ohm aluminum voice coil for vast cone excursions, durability, and heat dissipation under high power
Extra-stiff 10" nomex flat spider for greater restoring force and linearity
