Alpine's latest SWX-1243D is priced around 500 $
But boy o boy the design is totally jaw dropping!
RMS of :1000 W and a 3,000 watts peak, its sure going make your ride a club on wheels!
SWX uses a parabolic-shaped cone with a carbon-fiber layer out front and a Kevlar-reinforced paper layer at the rear. It is extremely lightweight, thus lowering the moving mass of the driver, and thereby improving efficiency.
Additional stiffening comes from Alpine's "force transfer assembly," an eight-armed injection-molded polycarbonate and glass fiber structure that supplies attachment and support to the rear of the cone and a collar at its base, which connects to the voice coil former.
This baby is sure going to PIMP YOUR RIDE!
