i dont know any manufacturers that put stuff like that in their manuals... that link i posted in the other thread where you were tyring to nitpick, MAYBE would have it. its the one from hometheaterhifi.com... there are ample reviews of the hgsII18 and the newer DD18 (same electronics except for parametric eq), look for some and see if they have the info that you desire. if it interests you so much, look it up and let me know. was there anything like you speak of about the tumult? you know the one that you linked to and were drooling over?

i only posted the specs to say that the three conditions that sh and you stated could be met.
