One pair of Paul Speltz Zero Autoformers. These are used by many with low impedance loudspeakers that wish to better match the comfortable operating impedance of their amplifiers. Connections for multipling a speakers impedance by 2X, 3X and 4X.You can read more about the Zero's at zeroimpedance.com
My Zero's were purchased 3 months ago for use with low impedance drivers and tube amps in a active bi-amp set-up. The results were great but I have decided to simplify my system with a pair of Tannoy Ardens I recently found. Now the Zero's are looking for a home.
$350 obo + shipping. (I paid $450 for them 3 months ago)
Thanks, Ron
