Q550 Floorstanding Speaker
Compact two-and-a-half-way floorstander
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) aluminium bass driver and two matching ABRs the Q550 delivers phenomenal audiophile performance with clarity and power.
Priced as a SINGLE speaker, please add two to your cart.
Magnetic grilles sold separately.
Promotion available until February 7th or while supplies last!
Promotion available direct from KEF and from your local KEF Dealer.



A new cone structure improves midrange clarity and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension enhances bass quality.
