A dual 15 corner horn using the CSS SDX15, and XBL^2 driver with 30mm (one way) x-max.

http://www.creativesound.ca/pdf/CSS-...ata-121107.pdf

The design is thermally limited (according to Hornresp), but could handle 6dB peaks within x-max limits above 35hz or so (worst case is 17.5mm at 1.8KW at 35hz, a null at 40hz, and a peak of 12.9mm at 55hz).

If built with a bifurcated path, each mouth would only need be 3200 cm^2 (about 100cm tall by 32cm wide, or 39.4" x 12.6"). Suggested layout would be like the later JBL Hartsfield or Klipsch Jubilee.

This isn't home theater.

In the context of PA, if it has good output below 60hz it's a subwoofer.

Looking at actual dance music program material content, I see very, very (very) little below 40hz.
