I thought this prv stuff was supposed to be pretty good?I have no idea about their actual build quality...but for your purposes (2-way comp set), and really most any purpose, their performance is going to be horseshit. They were poorly designed in terms of parameters, which makes them useful for about nothing. Also as M5 pointed out, you can't just add a random mid to a predesigned component set. There is dumb luck, and it might "work" okay with another mid in place of the Sony (but not the PRV) since the crossover is probably just a simple textbook design.....but the best bet is to purchase a new comp set rather than trying to cobble one together with unknown results.
