SP 18 | 18″ 6000 Watt Max Power Car Subwoofer

Description

Available with15″ and 18″
 
SP sub’s built with extremely high efficiency NEO motor. The motor utilizes N38SH Neo (heat treated). The entire motor would need to be nearly 250 degrees F before the magnet is affected in any way. This is nearly 40 degrees more than is required to boil water. 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 SPA12 features an enormous 30mm (1.18”) magnetic gap to ensure the coil is always under control. This motor drives a 4″ diameter 8-Layer Flat Wire Aluminum Coil with an extremely long winding (2.5” 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 8-layer coil – the 8-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.
