This is a two way all horn system meant to work from 27hz to 18khz at full output. It is bi-amped and uses a Xilica xp3060 feeding into two Crown xli800's. Linkwitz Riley crossover type and crossed at 600hz HF and 650hz LF and horizontally bi-amped. Time delay on the K-402 horn is 6.35ms.
The bass bin horn is based off of the MWM bin used in the Klipsch MCM-1900 systems. With a 66" throat depth on the OEM horns I could not get low enough for pipe organ music and I wanted to sit next to the 32' pipes. The Super MWM bass bin has a throat depth of 108" and is the best cleanest bass I have heard within it's HZ range. I have heard some go lower but the sound quality is just not there.
