well, nowadays i don't really have time to build an empty cab like i usually do because i'm refinishing a couple guitars, so i've browsed the web for an empty cab. then i came up across http://www.seismicaudiospeakers.com/ProductDetails.asp?ProductCode=SA-412%20EMPTY&gdftrk=gdfV21217_a_7c446_a_7c1303_a_7cSA_d_412%20EMPTY

would it be any good? i'd drop some v30's in the cabinet. or is it not worth doing at all..?

For the price i'd say go for it. Me and some of my bandmates were thinking about doing the same eventually.
