Might the difference in loudness be due to differences in the sensitivity of the driver(s) handling mids and highs vs that (those) handling low frequencies?
Bi-amping Snell Speakers Anyone?
I have recently bi-amped my system and the mids and hi's seemed to overpower the low end. The amps are identical so I just turned the volume down on the mid /hi amp. Is this normal in some systems or in a more perfect setup should I be making other tweaks to get the volume set on max for both?
