SM 15 | 15″ 7000 Watt Max Power Car Subwoofer

Description

Available with 12″ 15″ and 18″
 
SM sub’s built with tripe  high flux ferrite motor.  The motor utilizes Y35. As you can see from the photo on the T-yoke, this special shape increase transfer heat area, this design make the speaker more efficiency. The SM15 features an enormous 35mm (1.37”) magnetic gap to ensure the coil is always under control. This motor drives a 4” diameter 4-Layer Flat Wire Aluminum Coil with an extremely long winding (3.3” long) wound on a thick aluminum former to incredible levels of excursion.
 
We use 100% American made voice coils.we could take advantage of an extremely long 4-layer coil – the 4-layer coil keeps the mass and inductance down while allowing us to use such a long coil for incredible linear x-max while the powerful motor allows us to achieve the level of BL we desired.
