Q Acoustics 3040c Review

Design

• Choice of four finishes
• Magnetically attached grilles

It’s to Q Acoustics’ great credit that there’s nothing about the way the 3040c looks, or about the way it’s constructed and finished, that suggests it’s been built down to a price.

The 942 x 285 x 281mm (HWD) dimensions are pleasing – and it’s worth bearing in mind the width includes the bolt-on rear stabiliser that holds the floor-spikes and prevents the slender cabinet from toppling over too easily. The rear spikes can be adjusted from the top, too, which means it’s a lot easier to get the speaker level than it otherwise would be.

As well as being nicely proportioned, the 3040c cabinet looks good in a slightly curvy, understatedly elegant sort of way. There are no visible bolt-heads or anything nasty like that, even when you remove the magnetically attached grilles – and when the grilles are off, the satin nickel brightwork surrounding the three-driver array looks quite upmarket. The overall aesthetic is certainly a cut above what the asking price might lead you to anticipate…

The standard of finish is well up to snuff, too. Naturally, the cabinets are of MDF with a vinyl wrap – but it’s flawlessly applied, and any of the four available finishes – the Claro walnut of my sample, pin oak, satin black or satin white – look the part.

Specifications

• 22mm soft dome tweeter; 2 x 120mm Continuous Curved Cone mid/bass driver
• 43Hz – 30kHz frequency response
• 88dB sensitivity

Passive loudspeakers don’t usually have a lot of features, and that’s especially true of relatively affordable passive loudspeakers. But in the established Q Acoustics manner, the features the 3040c have are entirely appropriate.

On the outside, there’s a decoupled 22mm soft-dome tweeter sitting between a couple of 120mm mid/bass drivers – these are of the same Continuous Curved Cone design that debuted in a far more expensive range of Q Acoustics loudspeakers. The idea of C³ is to combine the strengths of flared cone design (clarity and control, mostly) with the low-frequency response of a straight conic cone – it’s proven technology at this point, and can only be to the benefit of the 3040c.

At the rear of the cabinet, just above a pair of extremely low-profile speaker cable building posts, there’s a bass reflex port. Q Acoustics provides port bungs, and it pays to experiment both with the position of the speaker relative to a rear surface and with the efficacy of the bungs themselves.

This is an arrangement, says Q Acoustics, that results in a 43Hz – 30khz frequency response and an 88dB sensitivity rating that means the 3040c should be no real trouble to drive.

On the inside, the 3040c uses Q Acoustics’ Point-to-Point bracing to minimise low-frequency vibration and enhance soundstaging and imaging, and also features Helmholtz Pressure Equalisers. These tubes nullify internal pressure, and markedly reduce the standing waves and sonic colourisation it can provoke.

Sound Quality

• Great clarity and detail retrieval
• Punchy, well-controlled low frequencies
• Slightly short of dynamic reach

Don’t doubt the Q Acoustics can play loud, hit hard and generally fill your listening space with sound – but this is not their defining character. By the prevailing standards of affordable floorstanding loudspeakers, the 3040c are notably sophisticated and even-handed in their approach.

A listen to A Tune for Us by Djrum and this balanced nature is made completely apparent. Frequency response, from the bottom end right to the top, is smooth and even – integration between the drivers is good and there’s no aural indication of the crossover point apparent.

The tonal balance is impressive, too – there’s not much evidence of the warmth and friendliness of tone that used to be the Q Acoustics thing, instead the 3040c are a neutral and non-interventionist listen in this respect.

There’s good bass extension here, but more importantly there’s good control of the attack and decay of bass sounds – there’s never any danger of the sound dragging or droning. Great midrange resolution allows voices of all types to project with plenty of energy and character, and the top of the frequency range is attacked with a polite amount of aggression – so treble sounds have plenty of bite but next-to-no edge to them.

And at every point, detail levels are high. Not only the broad strokes, either, but the more subtle, more minor, more transient stuff is identified and handed over too – and without the 3040c sounding especially analytical. Even the low-key harmonic variations (sometimes) apparent in voices or instruments get a fair amount of attention and put into convincing context.

There’s energy and positivity to the presentation when a recording demands it, but when it comes to dynamic fluctuations the Q Acoustics don’t have quite what’s required to reveal them in full. Oh, you’ll be left in no doubt when Caroline’s Total Euphoria shifts up the intensity and attack – but the 3040c don’t quite give full expression to the up-  and downticks in volume and drive.

And ‘don’t quite give full expression’ applies to rhythms, too. Yes, the Q Acoustics control their low-frequency activity well, and keep momentum levels up where they need to be – but there’s not quite the flow to rhythms that the best (fairly) price-comparable speakers can manage. Lumpy is to overstate it, but the 3040c are not as fluent as is absolutely ideal. Is ‘lumpy-ish’ a word?

Should you buy it?
