Had a couple pair of Klipsch Heresy's back in the day; one home audio pair and one pair of stage monitors. They were hyper-efficient and had nice dynamic range for the relatively low-powered amps I had available (Hafler DH200, DH220 and a Dunlap-Clarke Dreadnought 500). That made them very budget-friendly for a student and garage sound engineer of limited means. However and just like Czarivey, I came to find them overly fatiguing during home use at low volumes. They were especially sensitive to IM distortion. Never had the chance to try them with a good tube amp like the MC275, so I can't say if I might have stuck with the horn-loaded configuration. I them moved into the Rogers I'm still using today and have been more than satisfied with them for over 30 years. Hope this is useful for you!
Why did you choose a horn based loudspeaker?
Seems horns or waveguides have become more acceptable to modern audiophiles. So I ask horn owners why did you select a horn based system over the other options in loudspeakers? I myself mostly for dynamic range, lack of compression, image size and little to no listener fatigue. Plus I find a horn loudspeakers to be interesting in design and in appearance. I have a large collection of vintage and modern horn systems as well as dynamic loudspeakers.After 30 years of trying designing etc today I mostly prefer fully front loaded horn speakers. I know that horn speakers still are controversial but please try to be civil.
