Forte III Aren't the best klipsch has ever built.I believe for Music the CF-4's I have sound much better.I have the KV-4 also.
The CF-4's cost 2500.00,Forte's were a lot cheaper.Their Bookshelf Reference Speakers sound awesome just add a Good Sub and You will have a Killer System.
For Home Theatre the THX system they have sounds awesome .My Speakers are getting Old but in excellent shape but kliosch has improved their Crossovers,Horns and Woofers a lot since 1986 when I purchased Mine.
I had a pair of forte's they did sound good and still do but the best I don't think so.Their Pro speakers are very good also.I found a pair of Heresy's In Dallas TX back in 80's and bought them and they weighed a ton and sounded very good.I would have hated to have dropped those on my foot.
Good think It had a handle on it.I was stupid for ever selling those but I still have My CF-4's and want some bookshelf references for rear channel.
No Sub needed those CF-4's will pound you into submission.
Check out the THX Ultra2 System for $10,000.00.A lot of Theatres use them.
