I had been looking for a nice pair of JBL 4345's and finally found a pair. But after working out some of the particulars I found that the seller also had a pair of 4350's for sale. I can't listen to either because of the distance so I was looking for some feedback as to the Pros and Cons of each and if one would definitely be considered better than the other as far as sound quality. I plan on Bi-Amping the 4345's with one of the active JBL crossovers but not sure what crossover frequency to use. I would assume the same as the BiAmp only 4350 uses which is a 250HZ Xover since I can't find one rated for 290HZ. Looking for any and all feedback. Thanks
