Agreed. I would love to have budget room for the Bryston, but no. And there are some well-made active crossovers that cost a bit less. Fireblade, depending on the aprpoach you take, you might want to consider one of the Paradigm X-10/20/30 units. Bob referred me to them, and so I picked up an X-30 off ebay. I am not sure if I will actually deploy it, because I am still wrestling with my own sub integration. I am getting two servo subs (Rhythmik guts) built in cabinets like my ERRs. Those won't be done for a little while. In the meantime, I am experimenting with my old Orb powered subwoofer just to see what seems to work with the system. Progress is slow, because I have very little free time this time of year, and I have some room placement challenges, and I am still figuring out the best way to take advantage of the Ultra's multiple outputs. Plus, I am tasking my subs to do double duty in both the HT aspect of my system, and the 2/5.1 audiophile side.
Anyway, there are a number of ways to go about integrating subs, as well-identified earlier in this thread. I highly recommend
this series of articles on bass management and integration by the fellow from Red Spade Audio, because they will help reduce the trial & error work. I downloaded the software, procured the Behringer mike and mixer, and just started taking measurements. Having objective data to check against what your ears and brain are subjectively telling you is invaluable.
