- The R300 features a 5 inch Uni-Q driver array, which consists of both mid-and-high-frequency drivers. The purpose of the array is to have both frequencies coming from the same place, allowing them to integrate perfectly and create a convincingly natural sound.
- The R300 bookshelf speaker also features a 6.5 inch low-frequency driver below the Uni-Q array, which ensures a clean, deep and uncompressed bass output with superb dynamics.
- Surrounding the Uni-Q driver array is our new mid-range Z-flex surround, which projects audio more efficiently into your listening space and results in undistorted high frequencies.
- The R300 affords you the option to use either a single amplifier as your source, or to bring in a second amplifier to handle certain frequencies.
- At just over 1 foot tall and 8 inches wide, the R300 is the perfect candidate for any bookshelf, desktop, or countertop in your home or office.

R300 Bookshelf Speaker
A concert in your house, without the crowds.
The KEF R300 Bookshelf Speaker is the larger of the two bookshelf speakers offered in our R Series, and with more size comes more sound. The R300 bookshelf loudspeaker features 5 inch Uni-Q driver array atop a 6.5 inch low-frequency driver, both of which are housed in a cabinet that was specifically designed to eliminate any coloration of sound or unwanted frequencies.
Standing at just over one foot tall and one foot deep, the R300 is the perfect addition to any bookshelf, desktop, counter top, or anywhere else where an audiophile-grade speaker is needed.
The R300's Drivers
The R300 features a 5 inch Uni-Q driver array with a 1 inch aluminum dome tweeter at its acoustic center. This Uni-Q driver array offers pristine mid-range response, thanks to a braced magnesium/aluminum alloy cone and our Z-flex surround technology helping to properly project audio into your listening space. On top of all that, our 'tangerine' waveguide ensures a wide and even dispersion without interference between the high-frequency and mid-frequency drivers.
The R300 bookshelf speaker also features a 6.5 inch low-frequency driver below the Uni-Q array, which features a massive vented magnet assembly and a large, lightweight aluminium voice coil driving an inner hybrid cone. This setup ensures a clean, deep and uncompressed bass output with superb dynamics.
A Cabinet Designed For You
Your R300 will deliver gorgeously nuanced sound no matter if you're using it as a bookshelf speaker, desktop speaker, or part of a home theater system. The R300's cabinet contains layers of damping panels to reduce any muddying of the mid-range and bass. Even the airflow through the R300's reflex ports is managed using computational fluid dynamics to ensure acoustic clarity.
When you're listening to music through an R300, you're hearing exactly what the artist intended for you to hear.
