JBL Arena 8-8"203mm High-Performance Automotive Subwoofer 400W RMS 1200W Peak Sensitivity 2ohms 283V/1m 893dB Frequency Resp

Unrivaled power handling: The JBL Arena series is engineered to product uncompromising, mammoth base from an amplifier capable of delivering up to 1200/2100/2400 watts (Rated power on 400/700/800 watts RMS) of peak power.
Dual voice coil design: The Arena series dual 2/2.5-inch voice coils are each suspended in a separate magnetic gap. At low power, both coils drive the cone, cancelling any nonlinearities. As power increases, the other coil still applies force to the cone.
Die-cast, vented aluminum frame: The Arena’s aluminum frame features significant venting and heatsink fins for added power handling, and rigid construction to keep critical voice coil components in perfect alignment.
Composite paper full-edge subwoofer dust cap and cone: Composite paper’s combination of light weight and rigidity make it the ideal cone material to move a large amount of air without flex or distortion.
NBR (nitrile butadiene rubber) surround: The Arena utilizes a single piece NBR surround seal between the front and back of the woofer. NBR is environmentally stable, meaning you get the same elite performance from the Arena during Summer and Winter.
Progressive spider: The Arena’s progressive spider ensures restoring force to the cone, resulting a more musical experience from the subwoofer even in the highest excursion conditions.
