Featuring the all-new Uni-Q driver array and a 6.5-inch LF bass driver, the three-way KEF R300 lacks for nothing. Its stylishly uncluttered appearance beautifully complements the fast and clean mid-range response, along with accurate and clean low-end frequencies. With dynamic, uncompressed and undistorted LF performance, the R Series R300 provides a clarity and realism many strive to emulate but few achieve.
