Thats one of the reasons they are called Hersey among others. All logic says they aren't supposed to sound that good , but they do. I had a pair in the Master bedroom for over 20 years mounted in the corners, they sounded great. They were the later models but still had the T-35 tweeter, but were just built before the improved models with the 3rd order crossover to protect the tweeter. They ran off my 2505 and I never put more than 10 watts tp them. The newer models are a little bright for me but that's what tone controls are for.
