One-off Super Big Reds, tri-amped with a one-off electronic crossover, and one-off passive eq units between the Marantz and horns.
Uses two Marantz 170DCs for the four woofers and a Marantz 1180DC for the preamp and horn amp. Cabinets are solid oak with 15.5 cu ft exterior volume. I got these from a recording studio that went out of business.
A meeting of the JBL/Lansing group was held here and everyone agreed these were the best sounding 604s (604E2s) anyone had ever heard.
