Impressive power handling
JBL engineers desgined the ARENA X subwoofer to produce uncompromising, mammoth bass from an amplifier capable of delivering up to 1,600 watts of power. Nothing else even comes close.
The powerful 2.5-inch voice coil is suspended in a separate magnetic gap. At low power, the coil drives the cone, cancelling any non-linearities. As input increases, the coil continues to drive the cone for incredible power handling.
Die-cast, vented aluminum frame
This sub's aluminum frame features significant venting and heatsink fins to add power handling. And since aluminum is a rigid material, it keeps the critical voice-coil components in perfect alignment while they travel through the linear excursion range.
Aluminum woofer cone and dust cap
Aluminum is well known for being light weight yet extremely stiff, making it the ideal cone material to move large amounts of air without flex or distortion.
NBR(nitrile butadiene rubber) surround
The JBL ARENA X uses a single-piece NBR surround seal between the front and back - an essential design feature considering the enclosure's high pressure level. NBR is known to be a tough industrial, environmentally stable material, allowing your sub to perform optimally whether it's Winter or Summer.
The progressive spider allows the cone to move easily under any reasonable excursion conditions, resulting in more musical experience from your subwoofer.
