The B2 Audio RAGEXL subwoofer series: 
With the RAGEXL, B2 Audio has gone beyond all previous subwoofer models and created the big brother of the RAGE models. They are available in 10", 12" and 18". At the same time, the RAGEXL 15 can handle a maximum power of 8000 watts!

They feature proprietary cast baskets in all models, which result in extreme XMAX and optimal cooling performance.

The oversized 11" wide XL-motor features numerous large flared vents to cool the high temperature 8-layer US aluminum voice coil. In addition, the XD pole (cross-drilled pole) further optimizes cooling.
The extra stiff dustcaps not only look good, but also provide the extra support you need when generating high SPL levels.
