No, I thought about it after WmAx suggested that I build one but that just isn't something that I would feel comfortable doing. I probably would have been second guessing that decision and later wondering how my self-built sub compared to others that I was looking at. I'm definately not disappointed with the SVS although maybe, as WmAx said, I could have built one that blew the doors off the SVS for similar cost. Oh well, I think that the SVS was worth the price for the performance that it gives.
