Dynaudio Sub 500 Piano Black Incredible Shape, Barely if Even Broken in All Boxes/ Manual

These Sub 500's are taken in a trade in from a client of mine that has a out of state home that is visited perhaps (if even) a few months out of the year. The Sub 500's get so little use that after hearing them, I must say I doubt they are broken in. The Subs are hooked up in a beautiful 5.1 Confidence C4, Center, C1 setup and have been stacked up in master/ slave setup for approximately 4-5 years. Although it sounds like awhile once you see them you would understand. This is a steal. SELLING 3 OF THE 4 *** 1 HAS ALREADY BEEN SOLD. ****PRICE IS EACH*** I rate them 9/10 simply because of age.
