The article is at the publisher, so it will be out within a few months, after which it will go on my site. I used 8 drivers per side at 4 ohms; if you want to stay at 8 ohms go either 9 or 16 drivers per box. I wouldn't go less than 8 drivers per box. It does need to crossover to tweeters at 6kHz, so stock up on some of those closeout Onkyos too, at a 1.5 to 1 ratio with the woofers. I'm using my arrays along with a Tuba 18 sub, crossed at 80 Hz; the Tuba 18 will actually appear before the line array does.
