Should I use Impedance 4 or 8?


Maybe someone out in Audiogon land can definitively answer a basic impedance question for me.I own Klipsch Lascalas paired to a Raven Audio Blackhawk. Obviously they are rated as 8 ohm and the Raven provides both 4 and 8 ohm taps. The impedance tests on Lascalas show the impedance going very low at certain frequencies. (Like 3 at some frequencies) I've tried the 4 ohm taps which does squeeze a tad of hum out of the tunes but it seemed flatter and duller.Any advice? Will I damage my amp? Why the downgrade in dynamics at 4 ohms?

Yeah. In my experience, disregard the advice some give to go with the tap that sounds loudest. I'm not informed on the science but I suspect more is going on than matching average impedance. My Audion 845 valve monos sound better on the 4 ohm tap into Coincidence Super Eclipses (92dB, nominal 14 Ohm) than they do using the 8 Ohm tap.
