Hi agarwalro,
Thank you for the compliments on the SubMersive. The Catalysts are certainly a significant investment, although remember they have 3 ICEpower amplifier modules and DSP for each channel with the final package designed and assembled here in the states. The amplification is a major contributor to the price of the Catalyst, and this amplifier is not sold to the DIY community (the DSP interface is quite clunky, but effective). I would also point out there is a lot more into the planning, design and execution of the Catalyst than is implied in describing it as "a DIY project." In fact, the only part exactly available to a DIYer is the coaxial driver from B&C, where even there I'm likely to move to a custom version later this year.
I developed these out of a need for a speaker to fully enable the use of the subwoofers I was installing (especially where 2-4 are used in a room). Interest grew after many were impressed with the results, and while expensive, anything similarly capable either costs much more or was not developed with domestic use in mind. They are built in small quantities where I do all of the testing and QC of the speakers myself, often the assembly as well. While they aren't intended for everyone, there are very few turnkey products with comparable strengths and capabilities, let alone at a comparable price. The case of Zigrivers starting from scratch without amplification already paid for makes the powered speakers much more attractive and cost effective, as he will need no amplification in the rack, just XLR connections out of the surround processor.
