The Advent 6003 (also known as the Maestro) was a 3-way floorstanding speaker, notable as Advent's first 3-way design, featuring a 10-inch woofer, a unique dome/cone midrange (around 5.5"), and a tweeter, offering a smooth sound, 8-ohm impedance, 90dB sensitivity (for the woofer), and designed for easy placement near walls for solid bass and good dispersion, weighing around 55 lbs.
I am helping the original owner sell these. They were purchased in the 80's and seldom used. They are in excellent condition and sound great. I don't need help selling them and I will take down the add as soon as they are sold. These are very rare, especially in this condition. If they weren't so large I would keep them for myself. I have seen these posted for more than I am asking. Please contact me if you have any questions. Thanks, Jack
