This subwoofer was created to match and aid the 1.618 3-way towers. Its main focus was to reproduce ultra low frequencies that the 1.618 could not reproduce and aid in overall low end reproducing. Low, flat and not “boomy” was priority one.
In conclusion; INSANITY! I can not begin to express how important it is to stuff this thing to the HILL with poly fill and for the love of god keep it turned down really low when you first start out. I nearly shat myself when I first turned it on, I wasn’t prepared. This is a VERY powerful sub, and being involved for years with car audio, I mean that. The gain is about ¼ of the way and I love it! Smooth, tight, accurate and excellent at reproducing lows. It tries to move across the floor when turned up half way, and be sure to use spikes. Once I got it tuned they way I like it, it definitely adds to the 1.618’s well.
