MDS,
First, I'm very happy for you. Love is a splendid thing, indeed.
Second...six months?!? It took six months to turn it up? Audioholic might not fit. You're more of a social basser.
That is excellent that it can do that, and at such a nice form factor. Are you considering any other subs besides another SB12-Plus? I love my PC-Ultra. Love it. It takes up about the same footprint as yours, but the trade-off is height. If you can fit in a cylinder (both volume-wise and aesthetically), I'd highly recommend that you give it some consideration. Either that or ask Greg to build a spare of Andrew's design and ship you one.
