What are the advantages over the A/V-2? I can get this kit with all the upgrades and MDF for $750 Canadian. If one was to take his time I don't feel that one would need to spend $800 on pre-built enclosures when it only costs $16 for the MDF to build a pair. I understand some people don't have the resources, which is fine. But I feel for the best bang for buck I better build my own enclosures. So, are these guys substanitally better then the A/V-2? Or should I just get the A/V-2's? Thanks!
