Sound Characteristics and Strengths of KEF R3

The KEF R3 will look amazing in most houses, furthermore, it has 3 color options to choose from, making it easier to choose the right finish to fit in nicely into your own home. Aesthetically, the KEF R3 will also look nice with most modern amplifiers. The first drive unit you will spot will be the KEF signature Uni-Q array, where a 5 inch (125mm) midrange driver unit houses a 1 inch (25mm) aluminum dome tweeter, and right below them will be a 6.5 inch (165mm) bass driver unit. A bass port is located at the rear of the speaker cabinet, providing sufficient distance between the speaker and rear wall is necessary. If the bass output is not up to par, you can try using the walls to reinforce the bass by placing the speakers nearer to them.

The KEF R3 is really impressive for a bookshelf speaker, just take a look at their frequency range of 38Hz-50kHz (-6dB) and in a typical room, the R3 can dig deeper down to 30Hz (-6dB). The frequency response will be 58Hz-28kHz (±3dB). The nominal impedance is 8 Ohms (min. 3.2 Ohms) which is great. The speaker sensitivity of 87dB is quite low. The recommended amplifier power range is quite wide which starts from 15 Watts to 180 Watts. If you are not planning to integrate a subwoofer into your sound system then probably you should get a high power output amplifier. These data have helped us filter down the potential amplifier choices.

We are quite taken aback by the amount and weight of the bass output, for folks who find it too much, you can just pull it further away from the walls which do provide a richer bass and more balanced bass response. The KEF R3 is really capable of digging deep into the bass extension and prominently reproducing the low ends. It may not be as powerful as the R series bigger brothers or when compared to an active subwoofer but for music sources, they are good enough in our books. The KEF R3 midrange is equally impressive as well, it handles the music with agility and grace. Vocals sounding natural, and with clarity, you can hear the plucking of the guitar strings in crystal clear sound quality.

The stereo imaging is extremely accurate and holds it steady no matter the music transients and how high the volumes are. The soundstage is superb as well, it is wide and has ample depth, along with the pinpoint accuracy of the music delivery, the KEF R3 provides you with a faithful music presentation with detailed resolution. R3 speakers are musical speakers that sound natural and never exaggerate to create that false excitement, it is their impeccable timing and precision that makes the KEF R3 a true entertainer for music playbacks.

They are really well-balanced bookshelf speakers which will perform great in a home theater setup, an active subwoofer will be recommended, because movies tend to be bass-heavy, and bookshelf speakers are unable to provide that low-frequency impact that a sub can do. KEF R3 will be overqualified for surround speakers but will be an excellent choice though. R3 standmounters are probably a little big to be desktop speakers. Since we have all the important data, it is time to show you the list of the best amplifiers that you can partner your KEF R3 speakers with.
