I picked up a pair of JBL 240Ti's a few days ago for $675. They came with the original boxes and sales brochure and they looked like they were brand new. I had a pair of L100t3's before these and sold them thinking these should be a great upgrade. But, I'm just not enjoying these 240ti's. The midrange sounds kind of muffled, there is not near enough highs at all, and they just sound soft. I liked the L100t3's sharp, somewhat bright sound. These sound almost warmer than the Polk SDA's which I had a while back, and that's saying something. Is there something wrong with my 240ti's? Do the crossovers need a recap? Could I switch out the tweeter for a 035ti and get my highs back? I miss my L100t3's right now. The only thing I like more about the 240ti is the low end. I'm powering them with a NAD 216THX amp and 116 preamp. I used the same setup with the L100t3's. I'm sure the attenuators are at 0 and all the drivers are working. I'm quite disappointed. I definitely expected better for $300 more. Is there any way to fix this lack of high end, and the problem with the mids?
