The Heresy speakers from the 70s don't sound like the new ones as, with good ancillaries, Heresy IIIs have a flatter and utterly listenable accurate top end. I don't think they even sound like horns particularly, except for their efficiency which seems to make them lively. I think there have been 2 updates since the 70s, the last in 2006.
Opinions needed on some Klipsch for 2 channel
The wife has banished my 2 channel audio addiction to a spare bedroom and I need some input on my selections. I have 2 klipsch rf7iis that front a 5.2 in the living room. Pushed by a Denon 4311ci. My wife loves them and won't surrender. My pioneer sx-1080 is the receiver I use for 2 channel and used to power the rf7s . I have JBL Northridge towers as well that I can't stand for stereo. I have been looking at some Klipsch KG4s as well as some Heresys. Looking for some opinions on the pros and cons of each. I listen to mostly vinyl and I like it loud.
