KEF Q Concerto Meta 5.1 Speaker System vs Bowers & Wilkins 606 & 607 S3 Speaker Package: which surround sound system is king?

It's a battle of the British hi-fi Titans today; and this time it's being fought on the home cinema battleground.

We are pitting two five-star 5.1 surround sound speaker packages against one another. Each is a fierce competitor – and a What Hi-Fi? Award-winners at that – but which one is worth your hard-earned cash?

In the KEF corner, we have the Q Concerto Meta 5.1 Speaker System, which combines the talents of the Q Concerto Meta standmount speakers, Q1 Meta bookshelf speakers, Q6 Meta centre channel, and Kube 12 MIE powered subwoofer.

And in the Bowers & Wilkins corner, it's the three-time Product of the Year winning 606 and 607 S3 Speaker Package. This includes the 606 S3 standmount speakers, 607 S3 standmount speakers, HTM6 S3 centre channel, and ASW610 subwoofer.

Both sound great, and they look good too, but which should take pride of place in your home cinema setup?

KEF vs Bowers & Wilkins: price

These two launched with a pretty significant price disparity, but the current-day story brings something of a plot twist.

When we reviewed each of these speaker packages, we found that neither was available to purchase at an all-in-one bundle price. This meant that we tested the KEF package at £3146 / $4050 / AU$5650, and the Bowers & Wilkins package at £2496 / $3799 / AU$3947 – those prices established by adding the cost of each component separately.

However, since we bestowed these systems with five-star reviews and various Awards, retailers have begun selling the packages as convenient bundles, with all components supplied together.

The Bowers & Wilkins system can now be found at a heavily discounted price of £1999 (at Sevenoaks Sound & Vision), whereas the KEF package is down to an all-in-one price of £2549.

It's worth noting that these systems don't seem to be sold in bundles outside the UK.

That still gives the Bowers & Wilkins system an edge in the pricing department; however, the KEF can be found at a much more comparable price than initially seemed likely.

**Winner: Bowers & Wilkins**

KEF vs Bowers & Wilkins: design

We won't beat around the bush here; there's one speaker package that we have been swooning over ever since it strutted into our home cinema testing room late last year.

The KEF Q Concerto Meta 5.1 package is a rather handsome set of speakers, especially in the all-black finish that adorns our review sample. The finish is good too; the whole system is furnished in solid-feeling wood cabinets and wrapped in quality vinyl.

This is the more expensive package of the two, but its more premium feel goes some way to justifying the extra outlay.

The Bowers & Wilkins package, on the other hand, still looks and feels rather nice and is plenty premium enough for the asking price. It looks suitably suave in all three of its available finishes; but the little touches make the KEF system the better-looking of the duo.

The top-mounted KEF tab on the front and surround speakers, paired with the fossil-like waveguide, Uni-Q driver array (more on that in a moment), and sharp lines, really seal the deal.

We should note that you will need to invest in appropriate speaker stands to accommodate either of these systems – unless you want to set them up at shin-height, which we wouldn't recommend.

**Winner: KEF**

KEF vs Bowers & Wilkins: features

Each brand features its own proprietary driver technology throughout their respective speaker packages.

KEF employs its Uni-Q driver array, which places the tweeter in the centre of the mid-range driver, and accompanies the company's “tangerine waveguide”, which supposedly removes the traditional “sweet-spot” position that is a common factor with other speakers, producing an overall wider dispersion of sound throughout your listening space.

This is backed up by the company's Metamaterial Absorption Technology (MAT), which is claimed to “absorb 99 per cent of the unwanted noise from the rear of the driver for pure and natural sound”, according to KEF.

Taking a closer look at each component, the Q Concerto Meta speakers feature a 10cm aluminium midrange driver combined with a 19mm vented aluminium dome tweeter in the Uni-Q array configuration, alongside a 16.5cm hybrid-cone bass driver with a rear-firing port that's used to tune the lower frequencies.

The Q6 Meta centre channel sports an almost identical driver setup, but it sports an additional bass driver.

The Q1 Metas have a slightly larger Uni-Q array, comprising a 25mm vented aluminium dome tweeter with MAT, and a 130mm aluminium cone for mid/bass purposes.

As we reference in our review, “while that driver is a few millimetres bigger, it’s also expected to do a lot more due to the lack of a dedicated bass driver.”

Finally, the Kube 12 MIE features a 12-inch woofer, powered by 300W of Class D amplification.

Jumping over to the Bowers & Wilkins package, the 606 S3, 607 S3, and HTM6 S3 speakers all feature the company's titanium-dome tweeter, accompanied by midrange and bass drivers made of B&W’s Continuum cone material.

The 606 S3 sports a 25mm-dome tweeter and a 16.5cm-cone driver, whereas the 607 S3 surround speakers feature the same dome tweeter and a slightly smaller 13cm-cone driver. The HTM6 is most akin to the surround speakers, with the same 25mm tweeter and two 13cm mid/bass drivers.

Rounding things out, the B&W ASW610 subwoofer features a 25cm paper and aramid fibre cone long-throw driver and 200W of Class D amplification.

Taking stock, we find that the KEF package is the more fully featured of the two. It sports larger drivers for the front speakers, with KEF's Award-winning MAT technology, alongside a more powerful subwoofer and the Uni-Q driver array that features in many other What Hi-Fi? Award-winning speakers.

KEF vs Bowers & Wilkins: sound

This is the all-important category in this head-to-head speaker package comparison. So which surround sound system comes out on top?

Well, the good (and diplomatic) answer is that both of these surround sound packages sound fantastic, hence why they proudly sit shoulder to shoulder on our current Awards list. We'll start with the B&W package as it is defending its place as our Award-winner for three consecutive years.

We pretty much had only good things to say about the 606 & 607 S3 package's sound performance in our review, citing its warm, rich and detailed sonic signature as being a key component as to why we score it so highly. It blends insight and agility, without sounding too lean or skipping important details; it truly ticks all of the boxes.

We find it to be dynamically impressive at each end of the scale, too. The delicate handling of low-level dynamics captures the subtle inflexions of emotion in dialogue, whereas the system's extraordinary subwoofer delivers punchy, controlled and tonally varied bursts of bass when required.

This is all packaged in a system that works harmoniously, with no obvious sonic mismatches or conflicts, and the dispersion of sound means that no obvious gaps are left between the channels.

If there is one small drawback to this system, it would be the scale of the sound. It's by no means a deficiency of the system as a whole, but compared with other speaker systems we have tested, we find that the B&W package isn't as spacious or large-scale as others on the market.

This is where the KEF system steps in. It delivers all of the above, and more.

We rave, in our review, about its rich, powerful sound that ticks all of the boxes. Detail, agility, dynamics, timing; it's all here, and it handles all of this with an added sense of scale that helps tip the scales into KEF's favour.

All of this comes at the minor expense of a slightly less tuneful subwoofer, but its controlled and precise bass presentation ensures it remains a very worthy component of this Award-winning system.

What really seals the deal is the KEF's seriously impressive centre channel. It delivers crisp and deeply detailed dialogue to an extent that it almost feels as if the characters are in the room with you. This natural, balanced and rich sound is supported by the talented Q Concerto Meta front speakers, which capture fine details with ease, and the Q1 Meta speakers are the icing on the cake, delivering a tonally matched surround sound experience.

**Winner: KEF**

KEF vs Bowers & Wilkins: verdict

The truth is that you would find little to complain about if you pick either of these systems, as they both deliver high-quality cinematic sound. That being said, the KEF system puts the extra outlay to good use, as it comes wrapped in a more stylish design, and puts an emphasis on upping the ante when it comes to scale and subtlety.

Bowers & Wilkins has delivered an impressive speaker system in its own right, so if you're looking for something slightly more compact and a touch cheaper, you definitely won't be disappointed if you opt for the B&W package.

**Overall winner: KEF**
