One of the latest in a long line of sub-£1,000 KEF standmounts, the R300 is pretty and technically interesting, being the only three-way loudspeaker here. It is one of the larger designs in the group and looks the part with clean uncluttered lines that give it an air of sophistication, helped in no small degree by the excellent finish (which comes in a choice of classic piano black, rosewood or walnut wood veneer).
It sports the latest version of KEF’s Uni-Q driver array which takes care of treble and midrange duties, and a 165mm bass driver, effectively making it a three way design. The 25mm vented aluminium dome tweeter sits mounted in the centre of the 125mm braced magnesium/ aluminium midrange cone, and a 165mm bass unit made of the same material handles the lows.https://www.youtube.com/watch?v=D2PvauRm3Zk
Crossover frequencies are 500Hz and 2.8kHz, which means they’re not done in the 1kHz region where the ear is especially sensitive – a key advantage of three-way designs. The cabinet sports constrained layer damping to lessen vibration. On the back there’s a reflex port and a terminal board with built-in, selectable bi-wiring links.
One of the finest sounding speakers here, this has much of what the best of the rest offer, and sometimes more. I’m first struck by the maturity of the sound; it has a smooth and extended treble, a clean and detailed midband and deep, extended bass – and it all integrates smoothly. It can help your baby have a good night sleep while staying in his best double stroller.
