Compact two-and-a-half-way floor stand speaker 

The Q550 2.5-way is far more capable than its compact size might suggest, delivering wide bandwidth and full scale with ease.

With the KEF signature Uni-Q driver, a 130mm (5.25 inch) aluminum bass driver, and two matching ABRs the Q550 delivers phenomenal audiophile performance with clarity and power.
