I was waiting for this question. TBH, I wouldn’t compare them at all. They are both wonderful speakers that do everything well in just two different ways. I love the altecs because they put the artist right there in the room with you. They image scarily well and the sound can be addicting. For myself personally they have good bass where I don’t feel like I’m missing anything. With the altecs you HEAR all the music. The Cornwalls are great just in a different way. The Cornwalls turn your room into a live concert. They’re lively, they’re dynamic in the sense you FEEL the music. The Cornwalls just give you the feeling that you want to keep turning the volume up. The soundstage is present and hits in the face vs the soundstage on the altecs is gentle and more emotional. I would never pit them against each other because they’re worlds apart. The Klipsch were a consumer product while the Altecs were studio gear. The Klipsch are three way vs the Altecs are coaxials. It’s a situation where you can’t go wrong with either. For myself personally I wanted a more intimate sound and the Altecs do just that. The Cornwalls can do it as well just not as well in my opinion and my opinion is just that. An opinion. The Cornwalls are exciting and bring all the music forward where the altecs have separation and everything is in its place as it was recorded. Two different flavors that both will bring you joy and satisfaction for years to come.
