One thing I don't believe I saw mentioned in the discussion of front duplexes is the carrying power of the sound with the tuned front duplex. The noises that are caused by these are certainly annoying when you're seated at the piano. However, I've heard more than one technician say that that noise contributes to the carrying power of the sound in a hall. Having never made any direct comparisons I can't confirm or deny this. Do others have comments about this?
