The ASW608 is a fine choice of subwoofer if you're really pushed for space.

This seriously compact B&W measures a bijou 26 x 26 x 33cm. Unsurprisingly, considering its provenance, this is also a rather natty-looking design, and it comes complete with lots of tweaking potential.

We looked at this tiny troublemaker's bigger brother, the ASW610XP and for £700, that bass box offers something rather different – but undeniably impressive. Can this sub make a similarly strong impression?

There are also two EQ settings – usually nominally for music and movies – and low-pass filter frequency settings.

Small but beautifully formedDinky this box may be, but there's still a 200-Watt amplifier inside this forward-firing, solidly made, sealed cabinet.

More after the break

It's not unheard of for comparatively small boxes to pump out fairly large amounts of bass, but producing really low bass notes usually requires a large driver to move large amounts of air.

So we're interested to see how the '608 fares.

Sure enough, the relatively small driver does fall a little short compared with others when it comes to digging really deep. Underworld: Rise of the Lycans provides plenty of opportunities for the sub to stretch its muscles, and the ASW608 turns in a fast, lively and punchy delivery.

There are undoubtedly shortcomings where deep basslines are concerned, but if it's a compact, solidly built box that you're after, this remains a fine option.
