I am currently using a XM9 Deluxe 2 way, and am very pleased with it. Like the others have mentioned, it isn't a cost no object model, but it offers many features and quiet performance for the dollar. I have found it to be PC sensitive in stock form. I have also talked with a fellow on AA about them, and he has upgraded his XM9 with an external power supply. I haven't tried it, but it makes sense to me after he explained it to me, and I will try it, as soon as cash and time allow. The point is, these crossovers are very flexable and have the potential to be upgraded with ease. Phil is also a pleasure to do business with, and he can advise you on many upgrades as well. Check them out at, http://www.marchandelec.com/ I highly recommend one!
