There are three full-size new Q floorstanders to choose from, each sharing the same audiophile-grade technology in the same basic configuration: a new generation Uni-Q MF/HF array paired with a long-throw bass driver of equal size, and two matching ABRs.
The difference is the size of the drivers: 130mm (5.25in.) diameter in the Q500, 165mm (6.5in.) in the intermediate Q700 and a class-beating 200mm (8in.) in the flagship of the range, the magisterial Q900.
