My sub's blown (as has my DSP, but that's another story) and is beyond economical repair:mad: :( :cry: , so I'm wondering whether to splash out money I haven't got on something like REL or try DIY (not just to save money but have some fun in the process). Have any of you guys built an active sub? If so, how did/does it compare with those available from established manufacturers. I vaguely recall Merlin's efforts but I fear SWMBO will bury me in it if I build one that big, it took her a while to get used to my Tannoy D700s;) . Anyway, I don't have the room. I'm after a complete good quality kit that I can assemble, rather than studying books and designing one from scratch. Something along the lines of about 250W amp and 12" driver, sealed box (?) to keep the size down. So any comments/thoughts? urls?
