About: JBL Arena 8 Series 8" 400W RMS Component Subwoofer 

The JBL Arena is the best subwoofer in its class that money can buy. Nothing else even comes close. Leveraging patented Selectable Smart Impedance (SSI) technology and features from JBL's Luxury Audio division where subwoofers have fill rooms far larger than a car, the 8" Arena takes a completely new approach to car audio which uses light and agile opposed 2-inch voice coils in magnetic gap to provide completely linear control of cone excursion all the way up to Xmax. Symmetrical Field Geometry™ design ensures linear cone travel and low distortion at virtually any output level. Surrounding the proprietary motor design are other high-tech materials, including a cast-aluminum frame,concave cone, a nitrile butadiene rubber (NBR) one-piece surround, gold-plated speaker-terminal binding posts, progressive spider and vented pole piece. This subwoofer handles an amazing 1200 watts peak power (400 watts RMS), and all of its parts work in harmony to cool the voice coils for maximum output.

Unrivaled power handling 

The JBL Arena 8 is engineered to product uncompromising, mammoth base from an amplifier capable of delivering up to 1200 Watts (400 Watts RMS) of power.

Dual voice coil design 

The Arena 8's powerful dual 2-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 and one coil rides out of its gap, 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.
