The problem with mounting your TV on the wall is that it can get quite tricky when you want to install a speaker system near it. The point of wall-mounting a TV is to free up floor space, so by definition floorstanders defeat the object, and although most bookshelf speakers can be wall mounted, their bulky dimensions often make them look gawky when placed next to slim flatpanel TVs.

The solution is to invest in a set of slimline wall-mountable speakers with the same sort of depth as your TV, and that’s where Mythos XTR-50 comes in. Made by American manufacturer Definitive Technology, these speakers measure just 38mm deep yet their creators reckon they deliver the ‘dynamic punch, wide frequency range and broad dispersion of full size speakers’.


There are four different models of speaker within the Mythos range – the XTR-60, designed for mammoth-sized TVs between 55 and 60in; the XTR-40 for 40 to 42in TVs; the smaller-sized XTR-20BP for on-wall surround sound use; and finally the XTR-50, which is designed for TVs between 46 and 55in.

The speakers are available individually or in systems. We
were sent a package containing three XTR-50 speakers, allowing you to place one
either side of the screen vertically and the other below it horizontally as a
centre speaker – all of the speakers can be used for either purpose.
With a crossover of 100Hz the system’s
distributor Pulse always recommends pairing it with a subwoofer, specifically
one of Definitive Technology’s Supercube subs. We weren’t supplied with one for
our test so we used an Acoustic Energy model

The build quality of the units is phenomenal. The enclosures are fashioned from hand-polished aircraft grade extruded aluminium, giving them amazing rigidity. On the inside Definitive has used stiffening ribs and channels to add even more rigidity to the aluminium and eliminate resonance.

The speakers are reasonably attractive too, styled in a sassy gloss black finish with the large removable grille taking up most of the front (you also get a magnetic Definitive badge to plonk on the front).

A little workmanlike perhaps – on the wall they just look like big black slabs – but that’s kind of the point. They’re designed to blend with their surroundings and not draw attention away from the TV screen, so on that score they’re perfect.


For wall mounting, you get all the required hardware in the box, but if you’re not exactly handy with a drill and screwdriver, rest assured that the XTR-50s can also be mounted on the supplied table stands. These are a cut above your average stands too, as they’re crafted from smoked tempered glass that has a real feeling of quality. You even get the bits you need to place the centre speaker on a table top horizontally – talk about covering all bases (groan).
