ound reproduction has gone through 
big changes in recent years. The advent 
of surround sound music and movie 
sources are changing the hi-fi landscape 
dramatically. Hi-Fi Choice continues to focus 
firmly on the reproduction of music in stereo, 
but it would be myopic to ignore multichannel 
developments entirely, especially given the 
development of SACD and DVD-Audio.  
Because of the space required to house a 
home cinema system, the 5.1 sub/sat 
combination has become a core multichannel 
market stereotype. Five small and easily sited 
satellite speakers cover the mid and top, and 
provide the surround effects, while the low bass 
goes to a subwoofer that can be tucked 
discreetly out of the way. This sub/sat approach 
might particularly suit multichannel systems, 
but it’s by no means a new idea, and is equally 
valid for stereo. HFC tested a batch of three-box 
stereo sub/sat systems way back in 1992; that’s 
practically prehistoric in home cinema terms.
B&W obviously expects to sell most of its 
new M-1 satellites as part of 5.1 systems, 
alongside one of three alternative subwoofers, 
but the ‘2.1’ or ‘three-box’ stereo option is 
clearly an integral part of the scenario, too. The 
press release claims the M-1 speakers front “an 
audiophile sub/sat system”, and full discussion 
of the stereo options is found in the very 
thorough manual.
For the purposes of this review, the M-1 
satellites were underpinned by the excellent 
PV1 subwoofer, which we reviewed in full in 
HFC 259. In fact, two PV1s were drafted in for 
some tests, because physically separating the 
bass sources gives more even room-drive. 
That’s really a separate issue. The superior 
performance of the PV1 is already a given, and 
the main purpose here is to evaluate the little 
M-1 satellite, and see how well it lives up to its 
‘audiophile’ billing.
‘Son of Solid’ is the first reaction on 
unpacking this system, though that’s largely 
because both the M-1 and the previous Solid 
designs feature an integral swivelling stand. In 
fact, this new model is not only considerably 
smaller and more flexible, it also, ironically, 
feels a whole lot more, er, solid. Picking one up, 
its considerable 2.7kg weight comes as quite a 
surprise, since the enclosure is probably no 
more than a litre or so in total volume (think 
Tetrapack). Back and sides are a single alloy 
casting, while the baffle, top and base is made 
from tough ABS plastic. And if the alloy itself 
is inherently very stiff, rigidity is further 
enhanced by the curvaceous shape.
How small can you go? That’s the key 
question the designer of any satellite speaker 
must confront. Make it too big and no-one will 
buy it; make it too small and you can kiss 
goodbye to all hi-fi pretensions. The M-1 looks 
a little larger than many of its rivals, which 
should be a performance plus, but is still small 
enough to look cute. Priced at £125 per 
speaker, it’s hardly the cheapest satellite 
around, but the serious engineering content 
and clever design justify the asking price.
A two-way port-loaded design, it combines a 
100mm main driver that has an advanced 
80mm fibreglass cone, with a 25mm metal 
dome tube-loaded tweeter. The crossover is 
deliberately minimalist, and the mounting 
arrangements are clever and flexible; the unit 
may be used horizontally or vertically on its 
stand/base, or fitted to a wall bracket or a slim 
free-standing pillar. Cleverly, the stand also 
doubles as a tiny speaker terminal block. The 
M-1 is available in black, silver or white.
SOUND QUALITY
The satellites naturally have limited bass 
extension, though they work well enough 
down to around 140Hz. This matches 
seamlessly to the PV1, which may be fed either 
via its (unfiltered) line-level phono input, or 
using the speaker-level connector with the 
filter set to maximum bandwidth (150Hz).
