I read the product brochure which lists the depth as 13 inches. I am planning on placing this on top of my dvd player ( I'll spare the long story here but let's just say there are advantages to me not moving the dvd player ) for better ventilation and heat dissipation. My DVD player is 12 inches deep as measured across the top of the unit. I noticed via the on line review of the 622 that the "feet" are slightly inward, and I was curious as ot how far apart the feet are from front to back. Thx of rnay help!
