Graham Audio LS5/9 review

Most hi-fi enthusiasts have heard of the BBC-designed LS3/5A speakers. This tiny monitor was introduced in 1975 and has built a cult following thanks to its natural way with vocals and terrific stereo imaging. Given its small size and age, it will come as no surprise that it has limitations too, with restricted large-scale dynamics, an inability to play loud and limited bass reach, the most obvious.

The BBC also designed a bigger, more ambitious option, the LS5/9. It was released eight years after the LS3/5A and was intended to serve as a critical-listening monitor in modestly sized studios where the company’s bigger models just wouldn’t work. Its job was to allow the sound engineers to optimise all aspects of the broadcast/recording from microphone placement to overall sonic balance.

The BBC is a broadcaster rather than a speaker manufacturer, so as with its other designs, the LS5/9 is made under license by third-party companies such as Graham Audio. The Devon-based speaker manufacturer proudly proclaims its official licence on the packaging of these speakers.

Given that there are unofficial versions of this LS5/9 on the market, that seal of approval, at the very least, is a statement that the company has stayed faithful to the original design.

Design & build

The LS5/9 is a medium-sized, two-way monitor. It stands 46cm tall and has an internal volume of 28 litres, compared to the mere 5 litres of its smaller sibling. The front-ported cabinet follows the BBC’s favoured thin-wall construction method.

In this monitor, the enclosure’s panels are made of 9mm birch plywood and then heavily damped to move any resonances away from the all-important midrange region. Most current designs take the opposite approach, using thick panels that are more rigid but have resonances higher up the frequency range into areas where our hearing is more sensitive.

The LS5/9 is available in two standard hand-matched real wood veneers – cherry and oak – and three more premium options: ebony, rosewood and walnut. In a nod to modernity, Graham Audio has included magnetically mounted grilles for neatness.

Overall build quality is excellent. The oak veneer on our review sample looks lovely, while fit and finish are as good as the price point demands.

It isn’t possible to buy the original LS5/9 mid/bass unit, so Graham Audio, in partnership with Volt Loudspeakers, developed a new driver that complies with the BBC’s specifications. This 20cm polypropylene unit uses a rigid die-cast aluminium frame and has what is claimed to be a ‘massive’ motor assembly. Each driver is hand-assembled and tested by Volt.

OEM driver supplier, Audax, still manufactures the LS5/9’s official tweeter, and that’s what Graham Audio uses. This is an unusually large 34mm soft dome that is protected by a fearsome-looking metal grille.

Its output level is factory-set, but it can be tweaked to match your listening environment using exposed connections on the front panel. This involves moving a soldered wire between the three options (-1dB, 0dB (level) and +1dB), so it isn’t a particularly convenient thing to do. In most cases, we suspect that people will leave well alone.

The LS5/9’s crossover is relatively complex in design. It uses high-grade polypropylene capacitors and, unusually, a tapped autotransformer to equalise the tweeter level. The result is a sensitivity of 87dB/W/m and a nominal impedance of 8 ohms – pretty standard numbers for a speaker of this type.

Compatibility

Indeed, these speakers don’t prove particularly hard to drive. We try a range of amplifiers from Arcam’s A15+ and the Cyrus 40 AMP to our reference Burmester 088/911 MkIII pre/power without issue.

Our main sources are Naim’s ND555/555 PS DR music streamer and the Technics SL-1000R/Kiseki Purpleheart MC feeding a Cyrus Phono Signature/ PSX-R2 phono stage.

It pays to take care over speaker positioning. In our 3 x 7 x 5m listening room, the LS5/9 sound best around 70cm out into the room, angled in towards the listening position, though their controlled lows make a closer-to-wall position acceptable.

Once optimised, they provide a relatively broad listening sweetspot and their presentation remains impressively consistent as we move around the room. This trait points to great integration between the drive units and a well-calibrated crossover design.

These monitors are voiced to perform best with the grilles on, and they will sound a little bright and forward if you don’t use them this way. Aim to have the tweeter around ear height for the most balanced results.

Sound

Note, despite the age of the basic design, the LS5/9 speakers are highly revealing. If there are any shortcomings in your amplifier, source or the recording you play, they won’t be shy about telling you.

If you are at all familiar with the much more forgiving LS3/5A, that might come as a bit of a shock. Remember, the LS5/9 were designed as proper critical-monitoring speakers, and the LS3/5A were not; the ability to dissect recordings and highlight flaws further up the chain is the bigger speaker’s raison d'être.

Given their intended purpose in life, it comes as no surprise that the LS5/9 are even-handed and essentially neutral. They’re not massive boxes, so we wouldn’t expect seismic bass from them, and we don’t get it. But the lows they do produce are taut, articulate and dovetail seamlessly with the midrange.

As we play Kendrick Lamar’s Humble, it is hard not to admire the LS5/9’s insight into low-end subtleties and their ability to play loud without stress. Bear in mind the design’s age, it is even more impressive. The BBC’s original specifications stipulate 100dB monitoring levels, so the ability to play at high levels was baked in from the beginning.

Their midrange is another highlight. It is beautifully natural, conveying the likes of Aretha Franklin and Gladys Knight with the passion and body they deserve. We love the unforced character of these speakers and the way they deliver so much detail without sounding artificially etched or aggressive.

Sure, that tweeter isn’t shy about revealing hard edges or brightness in recordings, but given a good enough signal, it remains decently refined and insightful.

Stereo imaging is another strength. As we listen to Tchaikovsky’s 1812 Overture, it is hard not to be impressed by the sense of dimensionality and scale. Instruments are placed with precision and refuse to blur as things get busier. We don’t find the soundstage especially spacious, though we do like the convincing way image depth is layered.

Good as these monitors are, there are areas where the age of the design shows. While they excel at conveying low-level dynamics, the kind that communicate the feelings in lyrics or the subtle change of intensity of instruments, they don’t deal with larger dynamic contrasts with as much conviction. The very best alternatives at this price have a broader dynamic reach and convey sonic authority better.

We would also like the LS5/9 to deliver rhythmic drive with a bit more verve and precision. Their analytical approach to music replay has plenty of appeal, but it would be nice if a song like Michael Jackson’s Black Or White was rendered with a greater sense of propulsion.

Verdict

The LS5/9 are a piece of hi-fi history, and should be judged as such. We wouldn’t expect a classic car from the ’80s to be better than current designs in every aspect, and nor would we expect that from any piece of hi-fi.

The shock is just how excellent these speakers sound by current standards. Feed them a good enough signal and their superb midrange, insight and finesse shine through. They sound authentic in a way that still eludes most price rivals, and while there are aspects of their performance that fall slightly behind the very best at this price, these aren’t enough to dull our enthusiasm.

The LS5/9 design is a testament to the quality of the BBC’s engineers of the time, as well as an indication that speaker design hasn’t progressed over the decades as much as we would like to think. Graham Audio has done a great job bringing it to life.
