Seventy per cent of a film comes out of this one · review
A four-woofer centre from a range that also makes matching floorstanders, surrounds and height modules — which is what makes a system out of a speaker.
The bottom line A well-built centre from a range that lets a system grow — with the two figures that would let it be compared left unpublished.
Polk’s Monitor XT line includes floorstanders, bookshelf speakers, surrounds and a height module. Buying a centre from it means the front three share drivers and crossover design, and a voice moving across the screen stays the same voice. That is timbre matching, and it is the strongest argument for choosing within a range.
Four 3-inch woofers. Each moves less for the same output, which lowers distortion at the levels dialogue actually occupies. The cost is width: this is a wide cabinet, and it needs the shelf.
A defined mark with frequency response requirements, so it is checkable. What it does not describe is sensitivity, impedance or how the speaker sounds — and this listing publishes none of those.
Sensitivity and impedance. In a centre channel, which works harder than any other, those two decide whether your receiver drives it comfortably. Canton publishes both on this shelf; this listing does not.
At the centre of a Polk system. In a mixed system it is a good speaker whose main advantage — matching — does not apply.

They move a similar amount of air with less excursion each, which lowers distortion at a given level. They also make the cabinet wider. It is a design choice rather than a hierarchy, and in a centre speaker under a television, width is often available where depth is not.
It is a defined mark with frequency response requirements attached, so it is more than a marketing phrase. What it does not tell you is how the speaker sounds, and it says nothing about sensitivity or impedance — the two figures that decide whether your receiver can drive it.
80/140 W · 8x dB sensitivity stated · 30–30 000 Hz · crossover 400/3 000 Hz · 160 mm woofer
The only speaker in this catalogue with a complete published specification — sensitivity, frequency range, crossover points and driver diameters, all stated.
Best for: A system built from components where the centre has to be chosen on published figures rather than on a brand.

≈ £69 / 79 €
Passive centre · FSC-certified wood cabinet · designed to extend Ultima stereo sets · revised crossover
