Product Description

The SD-2 woofer was born of the need for a woofer as close to the performance of the SA series as possible but with significantly less mounting depth. We started with the same heavily tested and proven cone, surround, and spider assembly of the SA line. From there an all new motor was engineered using half the magnet height of the SA line combined with a solid back plate. The solid back plate allows the SD-2 line to be mounted directly against the enclosure wall eliminating the need for venting space behind the motor assembly -- this reduces effective depth requirement by another inch! The SD-2 line is still able to effectively vent the voice coil through 16 holes drilled around the basket perimeter as well as a vented voice coil former allowing it to handle it's rated 500-watts RMS with ease.

SD-2 8 D4 - Sundown Audio 8" 300W RMS Dual 4-Ohms Subwoofer Review

I initially had a JBL GTO804 installed powered by a JBL GTO-501EZ Amp operated with 300W @ 4ohm, and the sub sounded ok at low volumes, but if I tried to cranked the volume even halfway you could hear the sub bottom out pretty badly. I swapped the sundown sub into the same box, same amp (although with the voice coils wired in parallel the amp was putting out 500W into 2 ohms), and the sundown by comparison is night and day. This sub puts out seemingly bottomless bass, shaking not just the mirror but your whole body. The sub says its rated for 300w, but it handles the 500w amp just fine even at high volumes. The only downside is that I've now found every rattle in my car, which I suppose means mission accomplished for sub, now time to find some dynamat. Overall totally pleased, this is the best sub I've ever owned, and worth every penny.

My only complaint? I can't find a fault with the sub, but as a relative newbie, it would have been nice for the sub to ship with instructions for how to wire up the voice coils (took a few minutes of internet searching to find a good tutorial).
