These things MUST GO, no reasonable offere refused! I have to much stuff and it's time for spring cleaning. Acoustat Model 3 with MK121-2A interface. Socks recently removed and cleaned and diaphragms were inspected and are in good condition. These speakers DO NOT have the "Medallion Modification" but very good condition. Original box and manual for the panels as well as the MK121-2A interfaces. I will ship speakers within 5 days of cleared PayPal payment. PayPal users add 3.5%. Any questions please email.
