We have had the XVR-1 in the system for a year and are very pleased with it. It is capable of literally thousands of different cross-over configuarations at different slope adjustments. Importantly, however, you should be aware that this XO requires manual adjustment. That means that it is up to you to remove the cover and make each micro adjustment yourself by moving the jumpers around on the circuit board. Finding the configuration that is right for your ears is a trial and error process that can (and should) take time as you experiment. Also, you need to proceed with care, because one can screw it up (I did and blew several fuses). However, once you get the theory of the machine in your head, its fun. The folks at Pass were very accommodating and helpful as I went through the process.
