SUBWOOFER horns are built underneath the floor in a cavity 1 meter deep. Each horn is driven by 8 x 18″ (47 cm) woofers. A total of 16 woofers.

Each horn is 9.5 meters long and has a floor mouth area of 2.2 square meters and reproduce starting from 10 Hertz FULL POWER. The real mouth area IS NOT the one on the floor. The real mouth have to be considered together with the side vertical frontal panels.

I've seen that before, and it is indeed beyond ridiculous. I wonder where it's located - the text obviously seems translated from another language or written by someone who speaks English as a second language.

RD has been updated a few times, but it was built a long time ago.
I remember this when I first started getting out of car audio and into home audio before the home theater revolution started, so it's been years.
