About this item

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.

About Us

Founded in 1961, KEF has been providing the world's audiophiles with unparalleled sound quality, field-leading acoustic research, and a standard for everyone else to live up to. From classics such as 1975's world-renowned KEF LS3/5A to modern landmarks like the Blade and Muon, KEF strives to bring the natural beauty of live music and the power of spoken word completely unaltered to the ears of its users.

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.

Simply outstanding speaker!

Reviewed in the United States on June 17, 2016

Verified Purchase

Outstanding sound. Well balanced. I am partial to a good mid-range and these do not disappoint. I purchased these after researching many speakers and reviews. Went to music shops as well. The B&W's or Klipsch do not hold a candle to these. Piano music makes you feel like you are in the hall. Great speaker even at low volumes. For a small package these speakers really produce great sound covering excellent highs to bass. I use these strictly for music in a smaller space. Well built, excellent quality. I use bi-wired (separate posts on back). Finish quality is great. They come with a front screen, but look great with out it. Although they can take high powered amps, I am using a Peachtree Nova 65SE amp which puts out 65 watts per channel and it powers these just fine. Of course, I am not looking to blast the plaster off the walls, these do however handle volume well. They handle my eclectic music taste very well. I think the R300's would be a waste to use these for theater use, just too good for that.

Lows and mids are great. Having trouble with highs, but that's my environment, not entirely from the speakers. If you like acoustic music these are the best.

So after over 6 months of research I decided on the R300. I have them with the Peachtree Nova150. If there was ever a match made in heaven. The Kef at high volume shines! Appropriate bass response with crisp, but not harsh highs. I listen to Miles, Sade, all the way up to some heavy rap, and the Kef does not disappoint. Anything I put on sounds like I’m in a private studio session with the artist. The one thing I noticed is that you have give them volume for them to justify the price tag. Once you turn it up though, be prepared to have your socks knocked off!!! I realize the number of exclamations in this review may be excessive, but once you hear the pair you will know why. My wife (who is completely ignorant to high end sound) is a fan, and is now interested in audiophile quality equipment. Now that’s proof of how good it sounds!!

Gorgeous speakers and cabinet - sound not up to par

Reviewed in the United States on March 29, 2018

Verified Purchase

I recently bought a pair of R300 speakers. I purchased from Amazon since the nearest dealer is several hundred miles from my location.
Running stereo 125 watts .08% THD
I listened to various music for several weeks and really liked the lower midrange and lows, but the high end is just not there. I’ve owned JBL, Infinity, Polk, Definitive Technology, Golden Ear over the years and have never experienced such an absence of high-mid to treble as with the R300s. Some recordings when played had an instant – ‘that sounds wrong and dull’ sound. I mean on some recordings the instant they start playing the R300s make you turn your head and wonder “what is wrong with these speakers?”
After about three weeks of listening to music and watching surround sound movies I purchased an A/B switch and after an hour of careful listening it was very apparent (much to my disappointment) that my Klipsch RB 61 II speakers were overall clearly superior to the R300.
Now the R300s did produce a small amount more detail in the mid region, but were very lacking in other areas.
I then had my wife sit in the listening room (she had no idea which speakers were which, had no idea of the cost of the R300s and was not biased in any way)
I quickly switched input between the speakers and she always said speakers A (Klipsch) sounded better than speakers B (KEF). Again not knowing which speaker was playing she said the A (Klipsch) sounded like the musicians were more in the room, the soundstage was much greater and didn’t sound as dull as B (KEF). I asked her if one sounded more like a blanket was put in front of it and then removed – she said yes – speaker B sounded as if it had a blanket in front and when changed to speaker A the blanket was removed.
She did say speaker B sounded good, but A definitely had a much better sound.
Her thoughts were exactly in-line with mine – the Klipsch sounded SO MUCH BETTER. We listened to The Beatles, Dire Straits, Don Henley, Shivaree, The J Geils Band, Yes (Fragile) and more.
On Abbey Road, John Lennon's voice sounded more like McCartney than Lennon - that little edge to Lennon's voice was gone (returned with the Klipsh) The opening track on Don Henley's "End of the Innocence" was dull - so dull that it made you look at the speakers and wonder what was going on. "Whammer Jammmer" by J Geils (lots of harmonica) reminded me of listening to an old 8-track tape with a dirty head on the player (most of you will not have had that experience, but believe me it is low-fidelity)
I did (several times) check the bi-wire link connection to ascertain that I was not in bi-wire mode.
On some recordings you could hear more detail in mids and lows that weren't quite as evident with the Klipschs - but it was not enough to justify such an expensive item. Highs such as cymbals were less pronounced, less natural, and more in the background when compared with the Klipschs. Now, some will say the Klipschs have harsh highs - this is apparent at very high volumes, but normal to loud I don't find them harsh. At least the Klipschs don't turn your head and make you wonder why the heck the sound is so dull and missing.
Now in fairness for the KEFs, most jazz and acoustical music, Cat Steven's guitar and vocals sound really good - but not any better than the Klipschs. I believe that if that were the only type of music you listened to and didn't do an A/B comparison with another quality speaker, you would be happy with the sound.

Now, I only had about 50 hours on the speakers so some may argue that they were not broken in. I'll say this, With all the brands I've had in the last 40 years, not one pair sounded bad fresh out of the box like the R300s did.

I emailed KEF after I had returned the speakers - should have done so sooner. KEF responded quickly via email and wanted me to disconnect one speaker at a time to see if the dullness was with one or both speakers, but since I no longer had them I couldn't perform their test. I do know that both speakers lacked.
If the sound reproduction from these speakers was as gorgeous as the cabinet build and finish, they would be fantastic. The gloss white pair that I had was extremely well built and dare I say it "sexy". I really wanted to keep the R300s but even if they were only $400 for the pair, I would not be satisfied with them.

I really wanted to love these speakers

Reviewed in the United States on May 10, 2018

I really wanted to love these speakers. I did a ton of research on them and was convinced they would be the last bookshelf speakers I would buy. Excellent bass, outstanding midrange, and amazing imaging where some of the catch phrases that kept coming up while I was reading reviews.

They are beautiful and solid. For me, after giving them 3 weeks of break in and powering them with a Yamaha M-65 AMP rated @165W x2 (I biamped them as well), it came down to the fact that I heard too much treble and at loud volumes it was highly fatiguing.

At lower volumes they were better but occasionally I like to play music loud and these just didn't work in that regard. I have a dual 6.5" center channel with a horn tweeter. I also have a Rythmik Sub that I crossed over @80 Hz. If I really wanted chest thumping base, I had to get the center speaker involved. The Kef's and the subwoofer alone just didn't cut it.
