P1000-12

Dual 4 Ohms
1000 Watts
Power Handling = 1000 Watts peak; 500 Watts RMS each
Frequency Response = 25-1,000 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 polypropelane cone for low distortion at high volume
85 oz high-energy magnet for efficiency and high output
6” 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 2.5” dual 4 ohm kapton voice coil for vast cone excursions, durability, and heat dissipation under high power
Extra-stiff polycotton flat spider for greater restoring force and linearity
