RAMPAGE ELITE!

ALL NEW Rampage ELITE Series. 2012 had the seeds planted for the RAMPAGE. A direct derivative from the legendary & innovative X2C subwoofer with a 5″ voice coil. Although the RAMPAGE XM is based on a 4″ coil platform, its performance will not stand in the shade of its heritage. In many ways, it pushes the boundaries even further. The new basket offers better cooling with improved SAFT (Smooth Air Flow Tech) & has the ability of offering even more XMAX than the previous basket . 3.15″/ 80 mm peak to peak handled by the 315 mm / 12.4″ spiders (Or optional 14″!) , that are amongst the largest you will find on any traditional 15″ subwoofer (without the use of adapters), in addition the new basket offers a triple landing so you can customize the stiffness and spider size to your application.
OCAF

OCAF version II (Optimized Cooling And Flow) implemented in the new motor design has adapted the large flares from the X2C’s backplate. In addition the pole piece features a dual cooling system that leads the air more efficiently away from the voice coil. Even though the internal diameter of the coil is 4″, the outer diameter of 4.33″ makes this coil a widebody, coupled with an 8 layer tall winding, this design is made for daily torture or demo days!

The RAMPAGE XM’s motor has increased now to a QUAD 12″ slug variant coming in at 1400oz. Still we are able to keep the entire height of the motor to a mere 10% more than 2nd gen XM. With the longer Xmech, the added 10% comes into play.
Stiffness

Another tool was made for the XL composite dust caps with embossed B2 logo. The half spherical design with wider wedges stiffens up the cone, offering greater stability, and helps keep that transient response tight. So when the bass drops its on point. Using a slightly wider stretch foam surround there’s less mechanical parts that will limit your stroke.

Great price, but don't stack multiple wires
Size: 300A
I used this as a junction point on a 1 gauge wire. I added an 8 gauge wire to one side, and the cover would not seat. I had to bend and maneuver the ring terminals to make the cover catch. For the price of the items, if used without any secondary wires attached and interior use only, this is an unbeatable deal.
