wdecho, the Torii is a class A1 amplifier. Not placing "blame" on speaker or amp, but perhaps an incompatibility/synergy issue. I already have the amp, so I want to be reasonably sure that the F3s do not present the same problem I had with the KG 4.5s. Since the F3s are a 24 years newer design, plus much higher in the Klipsch food chain, I think I may give them a shot.
Shakey, I'm glad to hear that your Torii works so well with the Khorns. Are they old or newer? I just wonder if they have changed the crossover design in that speaker in more recent years.
Tube fanatic, Steve generally prefers crossoverless full range designs, or simple two way designs, with a cap on the tweeter. That's more than likely the type of speaker he made the measurements with. Those are probably they types of speakers he has in mind when he designs his amps.
derrickdj1, I didn't see what amp you used in your signature. Was it the Torii?
dbomberger, I've seen that video. I've spoken to Uncle Kevvy about my issue, and he offered me a "great trade in" on my Torii. Ha! I can't see that happening. I'm sure I'll love the amp with the right speakers.
I'll probably end up ordering the Forte 3s, since the only way I'll find out if they work in my system is to try them. Crutchfield offers a 60 day trial. I can return them if they don't work for me, with a $75 shipping charge back. If the F3s don't work, I'll probably go to Decware and get one of Steve's speakers.
