Hi, this is a good sounding pair of Nuance Advantage Speakers. They use E.D.T. Equalized Dispersion Technology. They are rear ported Bi-Wire ready speakers and the drivers sound really good. They use 8 inch woofers and 1 inch soft dome tweeters. They are 18 inches tall, 10 inches wide, and 11 inches deep. They have the grille frames with badges, but the material is mostly off, the cabinets have cosmetic and structural issues, that is why i am selling them for the parts price of just $15, firm. One cabinet is not as bad. Please email, call, or text to come see and audition them, thanks.
