Hey everyone, its me again. I have recently finished an ESB allignment shiva, with an Adire AVA250 amp, and this thing is really pretty damn sweet. The thing is, a friend of wants to add a subwoofer to his HT system, and there is a D-Box David 302 going at Costco for about $300 Canadian. It is really hard to audition because thats the only place I've ever seen it, and you dont get very good results in a warehouse with a lot of background noice. If someone has had any experience with the mentioned sub, could you please compare it to a well built ESB Shiva allignment? And dont forget, that it cost me about $500 in total *Canadian* to built the Shiva, while the D-Box is going for $300. Thanks a lot.
