If you want to have some fun with a speaker that will play all day with out fatigue and be stunningly dynamic competing with anything you own I would try DaveC's Modified RF25's which I have heard.
I couldn't live with most Klipsch stock networks after my experience or Dave' project which cost him $600 for the speakers new when he bought them and $600 in network parts. IMO you'd have to spend about $5000 to beat what I heard from them.
They will be far smoother and engaging then most of the Klipsch line.
This because IMO the stock networks are so cheesy because they are built to a price point. And I'm sorry the $30 does not equal the $300 Dave spent. And the bad news is the other Klipsch's your considering are just as cheesy with their parts.
I've owned many 2-ways over the years and I could never own a 2-way that uses anything bigger than a 7in woofer. The RF 25's use a 6.5in.
My reasoning is that larger woofers in a two way just don't have the speed for me and they seem less dynamic in the mids where the heart of the music is. BTW those networks Dave uses are stock values and the low end on his speakers as he say's is like you get a very extended low end response. The whole speakers sound is very coherent from top to bottom in such a way that it makes some speakers sound thin.
Once you experience something like this, it's hard to get into a commercial product without paying several thousand at least.
Great thing about Dave's speakers is they sound great at low levels or rock at high levels all on 10 watts of tube power!
Find a pair!
