Sound Characteristics and Strengths of KEF R300

KEF R300 has that stylish and elegant design that will fit right in most homes and also blend in well with most house decorations or themes. Their minimalistic look also makes it easy to match with most modern amplifiers’ design and we do not need to worry about mismatched aesthetics. The KEF logo plate at the top of the cabinet is a nice touch, then right below will be the KEF’s signature Uni-Q driver, that consists of a 1 inch (25mm) vented aluminum dome tweeter at the center of 5 inch (125mm) magnesium/aluminum midrange driver. Below the iconic Uni-Q driver will be the 6.5 inch aluminum woofer and a bass port located behind the speaker cabinet. There’s a potential that the KEF R300 is capable of pumping out ample high-quality bass.

The speaker sensitivity of 88dB is slightly lower than expected but is still not bad. The nominal impedance is 8 Ohms which is great. With the recommended amplifier power requirement at 25-120 Watts, it is wise to get high power output amps at around 90 Watts per channel if you are not planning to integrate a subwoofer. The KEF R300 has quite an impressive frequency response of 50Hz-28kHz (±3 dB) and is able to dig deep into the bass extension which requires a lot of power to reproduce such low-end frequencies. This is why getting high power amp is recommended. Using these details, we can start filtering down potential amplifiers that can be a great match for KEF R300 standmounters.

We are pleasantly surprised by how calm and relaxing the KEF R300 speakers sound, they are slightly more laid back sounding than their successor the KEF R3. You can certainly listen to them for hours and you won’t feel listener fatigue. It may not be as lively but the R3 still has that exceptional agility and rhythmic timing which make your toes tap from time to time. It just lacks a bit of punch and weight that really gratifies the music peaks. The smooth music delivery comes with excellent clarity and packs a lot of details.

KEF R3 is accurate and precise never missing a beat, projecting a soundstage that is fitting of their speaker size. The low frequency is ample and accurate as well but does lack a bit in the response time and is not as deep which we hope for. Probably this pair of bookshelf speakers need to be pair with an active subwoofer, to improve the bass performance and enhancing the overall sound quality as well. High-quality sealed subwoofers such as the Rythmik Audio F12SE Direct Servo sub will be an ideal choice. If you really like the composure of the music delivery that the KEF R3 speakers are presenting to you then you should leave out the subwoofer.

The neutral soothing sound quality and the laid-back nature require careful amplifier partnering, as too dark sounding amps may deliver a very dull or flat music presentation. All in all, the KEF R3 is a great all-rounder, we can see that they will do well in a surround sound system setup. Suitable for most music genres, as the speakers are always composed and don’t lose their footings. Now we have finally gathered all the necessary information regarding the KEF R3 bookshelf speakers and we will be able to start sharing with you the best matching amplifiers that you can go for.
