I call this my "Black & Gold" system. It features a Spectro Acoustic amplifier, preamplifier, and equalizer along with a Rotel CD player and a Nakamichi receiver. Speakers are Quart and Soniphase.
Although the Soniphase bass enclosures contain 15 inch woofers, they are rather anemic. Probably crossover related. Treble is an issue because of the huge horns. I set the equalizer to help with these two issues.
Oh, and thank you and everyone else for the compliments. I spend a lot of time in the garage, more so than my mancave (see signature and pic).
