I'm thinking your second pair of Forte's have a round terminal cup, the plastic plate where you hook up the speaker wire. Chances are your first pair have a more square cup. Yeah, that's exactly how they are. I did the sock trick to the horns on each speaker, and the drivers seem to be ok. One of the tweeters seemed to be a little weaker, but I really couldn't tell for sure- It wasn't obvious enough and I eventually decided I was just hearing things.(I'm going to pay attention to that though just to be sure) Thanks for the advice on that one Bonzo, but does it damage the speakers at all plugging up the midrange horn like that while playing them? I still haven't looked at the crossover components, but I'll get to that tomorrow after work. The rubber surrounds on passive radiator also seem to be glued on tight, although i noticed some slight cracking spots, on the outer edge near the screws, that go all the way around on one of them- I think its ok though.
Dennie, I'll check out the crossovers on that first pair of fortes as well. The guy I purchased them from never mentioned updating the crossovers, but you never know, he may have forgot to mention that. He was the sole owner of the pair.
Larry C- The lack of bass and distant vocals that don't locate well suggest to me that they might be out of phase. Reverse one of the speaker leads and see what happens. I'm sorry Larry, I guess I'm not quite sure what you mean here. I'll definitely try it though.
Anyway, thanks a lot for the advice guys, I'm still experimenting with them right now, and currently have them side by side doing an A-B comparison. I think I was a little harsh on the second pair of speakers. Really, they sound very similar to the first pair, and I won't have any problem giving them to my Dad. I must have been hearing things or something, because the bass match up the same on each pair, and they both have a great live presence. My ears must change on a daily basis, but it sure does help having them next to each other.
They do sound slightly different, though, and I really can't explain it. The first pair just seems to do vocals a little bit better, and has a more polished sound. Either way, I guess its not a very big deal. I wouldn't have known any better if I didn't have the two pair to compare to each other. I prefer the first pair, and now I feel that the second pair is going to make a great gift for Dad. I may end up updating the crossovers on the first pair down the road, but for now, I can relax a bit and enjoy the music.
