welcome...

if you were considering spending $700+ on a all singing all dancing sub such as the ones bluefakes.com sells... then I recommend you buy something that is 1000% better a BK Sub http://repgeek.com/showthread.php?t=88290

or if you want the DSSD, go with a eurotimez.com v5 then send to Vac for a relume and to seal the HEV.

Use the search function and any and all questions you have will be answered there!

enjoy the learning curve, its steep, but fun, and no one here shouts... much!
