Fyne Audio Cubitt 5 review: an expansive-sounding, attractive stereo speaker system marred by low-rent usability

Fyne Audio Cubitt 5: Two-minute review

It’s taken Fyne Audio less than a decade to establish itself as a deeply credible manufacturer of passive loudspeakers at a wide range of prices. The Cubitt 5, though, represents its first pair of active speakers — and they've got some serious competition to overcome.

At first glance, though, the system seems to have every chance. Its compact, well-made cabinets are available in a wide range of finishes, and are home to an intriguing driver array that draws liberally from the company’s very successful (and much more expensive) line-up of passive loudspeakers. Power is more than adequate at 240 watts, and the range of inputs (Bluetooth with aptX HD capability, line- and MM phono-level analog, optical and HDMI ARC) is very competitive, too. The lack of on-system controls is an odd decision, as is the lack confirmation of selected input or volume, and the remote handset that’s your only control option is unlovely.

Get the system up and running and you’ll have to ignore the unwelcome low-volume hiss that comes from each speaker before any music is cued up — fortunately it’s not an issue once your tracks are playing. Instead you’re free to admire the Cubitt 5’s abilities with detail retrieval, soundstaging, low-frequency authority and articulate midrange communication. It’s absolutely as confident as is acceptable when it comes to handling the top of the frequency range, but even here it’s not overtly ill-balanced or unruly.

Add in significant dynamic headroom, an expansive overall presentation and a disinclination to alter its stance in any significant way no matter which of its input options is in use, and it’s apparent that where the fundamentals are concerned, the Cubitt 5 has plenty going for it. Maybe not quite for the best stereo speakers on the market, though.

Fyne Audio Cubitt 5 review: Features

• 127mm ‘IsoFlare’ mid/bass driver with 19mm concentric titanium dome tweeter
• 240 watts of Class D power
• Wired and wireless inputs

The idea of positioning a tweeter in the acoustic center of a mid or mid/bass driver is not a new one, but it’s a rarity nevertheless, and Fyne Audio has been busily democratizing its ‘IsoFlare’ variation on this particular theme for a while now. The Cubitt 5 is just the latest example.

In this instance there’s a 19mm titanium dome tweeter positioned in the center of a 127mm multi-fiber mid/bass driver — the idea, as ever, is to create a single point-source of sound at the same time as optimizing driver integration and sound dispersion. The mid/bass driver’s surround is the company’s ‘FyneFlute’ design, the unusual pattern of which helps minimize unwanted energy from the pistonic movement of the driver. Each of the four drivers gets 60 watts of Class D amplification to power it — an all-in total of 240 watts really should be adequate in a system such as this — and the output is bolstered by a front-firing bass reflex slot. It’s an arrangement Fyne Audio suggests will deliver a frequency response of 43Hz - 34kHz.

The primary speaker takes care of all wired and wireless connectivity. The wireless stuff consists of Bluetooth 5.0, with codec compatibility up to and including aptX HD. Physical connections, all on the rear panel, run to a moving magnet (or high-output moving coil) phono stage accessed via stereo RCA inputs, a line-level analog equivalent also using RCAs, a digital optical input and an HDMI ARC socket. All incoming digital information is dealt with by a DAC of 24bit/96kHz resolution.

Fyne Audio Cubitt 5 review: Sound quality

• Expansive and controlled presentation
• Solid punch and decent dynamics
• Audible hiss when not playing

There’s a unique aspect to the way the Fyne Audio Cubitt 5 performs — or, at least, it’s unique in my extensive experience of products of this type. Connect the speakers together using the supplied umbilical, plug the primary speaker into the mains, turn the power on, and there’s an obvious and consistent hiss from both speakers. Is it loud? No, but it can be heard down the length of my listening room. Is it audible when playing music? No, not at all. So is it an issue? I guess not, unless you intend to use the speakers on your desktop, but I can’t pretend it fills me with confidence.

Which is a great pity, because when it’s actually playing music the Cubitt 5 is one of the best sub-$750 wireless stereo speaker systems I’ve heard so far. In virtually every respect, it’s an enjoyable, balanced and well-sorted listen.

With a vinyl copy of Julian Cope’s Peggy Suicide incoming via the moving magnet phono stage, the Fyne Audio doesn’t take its eye off the ball for a moment. It’s good where detail retrieval is concerned, and manages to stay on top of the finest details without sacrificing any sense of unity or performance. It creates a fairly large soundstage — it’s certainly larger than the cabinets that are producing it — and it’s coherent, organized and easy to understand.

The tonal balance is persuasive, too, the Cubitt 5 hits the plosives at the top of the frequency range absolutely as hard as it dares, but somehow they never quite get too edgy or overly hard. The midrange is sweetly communicative, so there’s confidence and eloquence to the way the system handles a vocalist. And while the claims for extension down to 43Hz are, I think it’s fair to say, a false alarm, the Cubitt 5 nevertheless bigs deep, hits hard and controls its low-frequency activity well. Rhythmic expression is very decent as a result, and the way the system handles tempos is similarly unforced and naturalistic.

There’s a fair amount of dynamic headroom available, so the Fyne Audio handles big shifts in volume or intensity calmly, and its overall attention to detail means that the more subtle dynamics of harmonic variation are given their due weighting, too. Frequency response is nice and even, too. The tendency to attack the highest frequencies can make it sound like the top end is being overstated on occasion, but otherwise the Cubitt 5 gives every area of the frequency range fair representation.

It’s winningly unconcerned about volume, too. Some systems can change their character when asked to play at bigger levels, but the Fyne Audio just gets louder. There’s no change in tonal balance or frequency response, and the stage maintains its shape, too. And the same is true when you change inputs — switch to a wireless stream of John Glacier’s Money Shows and the fundamental attitude and character of the system don’t alter in the slightest. It’s still balanced, insightful, punchy and just slightly treble-happy.

Fyne Audio Cubitt 5 review: Design

• 260 x 165 x 215mm (HxWxD)
• Available in five different finishes
• Supplied without grilles

It’s by no means an easy trick to pull off, but the Cubitt 5 manages to look discreet and interesting at the same time.

The ‘discreet’ part is mostly thanks to the 260 x 165 x 215mm (HxWxD) dimensions, assisted by some nicely curved cabinet corners and a selection of no fewer than five very agreeable finishes. My sample is in ‘olive green’, but ‘arctic white’, ‘midnight black’, ‘pearl titanium’ and ‘pebble gray’ are also available. No matter which finish you decide suits you best, you’ll find it’s the final flourish in a process that includes a very high standard of construction. There are no visible seams, and the soft-touch paint is flawlessly applied.

‘Interesting’ is mostly derived from the driver array that’s already been discussed in the ‘features’ section of this review, as well as the forward-facing bass reflex slot that somehow makes each speaker’s appearance easy to anthropomorphize. The not-quite-circular brightwork surrounding the driver array doesn’t do any harm when it comes to making this most functional of products look interesting, either. It comes as no surprise to me that Fyne Audio doesn’t see the need to supply the Cubitt 5 with grilles.

Fyne Audio Cubitt 5 review: Usability & setup

• Speakers must be wired together
• No app, no on-speaker controls, no input selection of volume indicator
• Nasty remote control handset

In terms of getting up and running, there’s really not a lot to get your head around here. Despite the fact this is an active system, only the primary speaker requires mains power — it transmits power, as well as data, along a supplied four-core umbilical cable that screws down onto the rear of each speaker. Once the speakers are connected together and the primary is powered up, it’s really only a question of positioning them to your satisfaction and then you’re in business.

Getting what you want from the system isn’t all that tricky, either, but neither is it all that satisfying an experience. This is not a Wi-Fi-enabled system, of course, so there’s no control app, which is hardly unheard-of in this part of the market. There are no controls on either speaker, either, which is rather less common. The primary speaker has an LED tell-tale that’s red when the system’s in standby and blue when it’s powered up. The blue light flashes when it’s following instructions from the remote handset that’s your only method of operation.

Given that the remote is all you’ve got, though, it’s a shame Fyne Audio specified what I imagine is the least expensive handset it could source. The look and feel is down-market, and the fact you’ve no indication of the source that’s been selected or the volume level that’s been specified only adds to the impression of cost- and corner-cutting.

• Usability & setup score: 3 / 5

Fyne Audio Cubitt 5 review: Value

Judged purely on the sound it makes, there’s no denying the Cubitt 5 offers very decent value for money indeed — once it’s making a sound, that is. The standard of build and finish only adds to the impression of money well spent.

But there’s more to it than this, of course — and as far as the experiential goes, the feel of operating the system, the sensation is undeniably low-rent. Which unfortunately undermines the impression of value the Fyne Audio system otherwise offers.

• Value score: 4 / 5

Should I buy the Fyne Audio Cubitt 5?

Buy them if…

Don’t buy them if…

Fyne Audio Cubitt 5 review: Also consider

The Cambridge L/R S system handily undercuts the Fyne Audio on price, and has an awful lot to recommend it both aesthetically and in audio terms. Not quite the room-filling ability of the Cubitt 5, mind you.

And the same is true of the Ruark Audio MR1 mk3, but if you want a well-specified and great-sounding system that’s genuinely small enough for desktop use and isn’t as pricey as the Fyne Audio, you need look no further.

How I tested the Fyne Audio Cubitt 5

Almost all my testing is done with the Cubitt 5 positioned on a pair of Soundstyle S2 speaker stands, joined together by their supplied connecting cable and with the primary speaker plugged into the mains.

Sources include a FiiO M15S digital audio player with aptX HD Bluetooth capability, a Technics SL-1300G with Goldring 1022 cartridge for vinyl via the phono stage, a Rega Apollo CD player connected to the optical input, and a Philips OLED806 via the HDMI socket.

Which means a lot of different content, stored in a variety of file types, and of many resolutions, is available — and then I listen for almost an entire working week.
