The LS3

The new compact monitor from Graham Audio, the LS3 is a similar size to the classic LS3/5 and LS3/5A, but uses modern drive units in a sleek cabinet finished in high gloss paint that compliments any interior style.

The bass driver is a newly developed unit that uses a polypropylene diaphragm and a die-cast aluminium chassis. It has an extremely smooth frequency response, meaning that the crossover does not need to be as complex as the BBC models, thus assuring high levels of transparency. Coupled with the bespoke SEAS tweeter, which is custom-built for Graham Audio, the results are truely monitor class.

In the usual Graham Audio way, the grille is held in place using magnets that are hidden, so the front of the speaker looks clean and uncluttered, whether you choose to use the grilles or not.

On the rear panel are a pair of high quality multiway binding posts that will accept the majority of loudspeaker connections.

Graham Audio is proud to present the LS3 under the iconic Swisstone brand - once the trading vehicle of one of the biggest BBC licencees.

    “...right from the start it was apparent that the LS3 is a very capable little monitor. The fundamental quality of the BBC LS3/5 (and LS3/5A) has always been just how well it reproduces the tonal quality and dynamic nuance of voices and acoustic instruments, and to my ears the LS3 displays a very good dose of the same seductive character. ...The LS3 would actually make a convincing case for itself based on only its mid-range performance, but it is also nicely balanced throughout the entire audio band without obvious emphasis, and its bass, while clearly not hugely extended in terms of bandwidth, has all the timing accuracy you'd expect from a closed box. Stereo imaging too is explicit and focused, and the tweeter displays a good level of detail without drawing attention to itself.”
