Hey Slappy, Why don't you look at NHT SB-3's, which are a closed box design that hits a low of 39. They sound really great when driven w/ 100-140 of Denon or B&K wpc. They are so NOT stereophile class D! Used you should be able to swing them into budget, if you save your lunch monies???
I auditioned them for a 3rd system which was broken down. I was overly impressed with them for the money. I sold them to Audiogon'R "Tankeny" who posted a really thorough review on here.
