first i would like to thank Brian and Hank for putting up with me, all my questions, and potential orders for a sub box. I decided to try it myself, and when I post pics tomorrow you will see it does not look anywhere as good as what they would have done (it is an ugly black box), but what the heck. This this rocks. 54L, sealed, 12" titanic mkII, PE 250W plate amp, stuffed with 2 lbs of polyfill. I just hooked it up, popped it in the corner, and put in the pod race scene, and the opening scene of LOTR: FOTR and almost knocked some pics off the wall. Threw in some Holly Cole and was amazed at how tight and deep it went, and what I had been missing. Thanks for everyones help. I could not have done it without you. Oh yes, the bookshelf speakers are GR Research AV-1s and I bought the raw MDF cabs from Brian (who does amazing work).
