Bass from a cabinet rather than from a subwoofer · review
Polk Audio Monitor XT70 floorstanding speaker review
The largest speaker in the Monitor XT range, which also contains the matching centre and height module in this catalogue — a system rather than a speaker.
The bottom line The anchor of a matched system: the reason to buy it is the three other speakers in this catalogue that go with it.
The argument is the range, not the speaker
The Monitor XT line in this catalogue includes this floorstander, the XT35 centre and the XT90 height module. Bought together, the front three share drivers and voicing, and a sound moving across the screen stays the same sound. That coherence is what a mixed system cannot have at any price.
What is stated
The Terylene tweeter and its position at the top of the range. Polk describes materials and hierarchy rather than publishing measurements, which is the house style here and is less useful than Canton’s approach elsewhere in this catalogue.
What is not stated
Sensitivity, impedance, frequency response with a tolerance. Those three decide amplifier matching and room behaviour, and none is in this listing.
The room question
A floorstander is a large cabinet that generally wants space behind it. Where the port is — front or rear — decides how much, and the listing does not say. In a small room with the speakers against a wall, that is the specification worth chasing before buying.
Where to start
These, and a receiver. The centre and the height modules are the next two steps, and buying them from the same range is the whole point.
Availability
On sale from 313 € to 389 € on the German, American, British, French, Italian and Spanish Amazon stores at the time of checking.
The Spanish Amazon listing is priced above 1.6× the cheapest store, which is normally a reshipping offer rather than a local price; it is left out of the range above.

What we like, and what we don't
Strengths
Part of a complete range — centre, height module and surrounds all match
The Terylene tweeter is shared across the range, which is what makes the front three sound alike
Passive, so the amplifier can be chosen and changed independently
Compromises
No sensitivity, impedance or frequency response with tolerance published
Its matching advantage applies only within the Monitor XT range
A floorstander needs distance from the wall that a small room may not have

Questions people actually ask
Do I need the whole range?
Not to start. A pair of these with any receiver is a good stereo system. What the range buys is a coherent path: add the XT35 centre and the XT90 height modules later and the whole front behaves as one, which is not true of a mixed system.
How far from the wall?
The listing does not state the port position, which is the figure that decides. As a rule, a floorstander wants some distance behind it; if the room forces it against a wall, expect fuller and less controlled bass, and check whether the maker supplies port bungs.
Passive pair · 500 W maximum stated · works with common hi-fi amplifiers
The entry floorstander: a passive pair with a maximum power figure and little else published, at the price where most people buy their first tower speakers.
Best for: A first pair of tower speakers, where the alternative is bookshelf speakers on a shelf.
