- Reviewed in the United Kingdom on 2 March 2025Size Name: MXT20BKVerified PurchaseThese Polk XT20 Speakers were purchased to replace a pair of Wharfedale Diamond 12.0s, which, while excellent, were found to be quite fatiguing over extended listening periods. The Polks also had a superior frequency response range, 38hz - 40,000hz vs 70hz - 20,000hz, for the Wharfedales, which should, on paper at least, give a much more pronounced bass response. In terms of build quality, the Polks were very well-finished (the fine-textured overall black cabinet finishing, a pleasing and modern looking alternative to the common 'black ash' vinyl wraps which adorn so many entry-level bookshelf speakers). The Polks did not have as solid a cabinet as the Wharfedales (an indication of thicker MDF construction and superior internal bracing). The Polks binding posts are also not as high quality as the Wharfedale's, which also boasts twin sets of terminals on each speaker for 'bi-amping'.
In terms of performance, however, the Polks were exceptional for what is a budget price. Clear and crisp high treble without being overly bright (with only a slight trace of high-end roll-off) and punchy, tight bass at medium to high volumes with no obvious signs of audible distortion. As with most speakers in this price range, lower volumes did lack a little definition. Only the mid-range performance was slightly subdued, in what was an overall fine attempt at creating a convincing soundstage. Being Rear-Ported, correct placement is also essential to contributing to a balanced soundstage.
When tested with a Cambridge Audio Axa35 Amplifier (8 ohm) and Axc25 CD Player, the speakers were easier to drive than their 87db sensitivity suggested, and would undoubtedly be more so with a more powerful integrated amplifier than the Cambridge. The Polks also responded extremely well to EQ, and are actually, by default, quite neutral, so can be 'tuned' quite effectively through Tone Control.
For this reviewer, the bass response - while excellent for a budget bookshelf speaker - is certainly not as powerful as other reviews seem to suggest, and a subwoofer would certainly enhance lower frequency response.
However, most pleasing of all, is the XT20s ability to provide consistent non-fatiguing listening for extended periods. This was evident through a diverse range of different genres from electronic EDM to Hard Rock, and is, perhaps, the speaker's greatest attribute in an entry-level speaker marketplace where listening fatigue is often cited as the reason why individuals upgrade to the next mid-price level.
Overall, an aesthetically pleasing, well-made budget speaker with surprising acoustic performance and sonic dynamics throughout.
For the extremely competitive price of £189, you can't really go wrong.

- Reviewed in the United Kingdom on 29 July 2024Size Name: MXT60BKVerified PurchaseI checked the Q&A for some info, as it was confusing, someone said, They were sold as a pair and came in 1 box, So I though bargain and hit buy now button immediately, Found out after waiting 6 days late, they're indeed sold as 1 item, ordered another 1, then had to wait a further 3 more late days delivery for the second 1 to arrive, but with that said and done, the wait was worth it.
After using the old speakers for 20 years, I decided it was time to upgrade, when I noticed they were not sounding like they used to. I'm glad I did, The Polk MXT60 towers are just so much better than the old set, I finally have the level of sound I used to have and then some.
I've noticed Polk MXT60, have a much brighter high end, seems like the tweeters are boosted, but I like that and even turned up the 16Khz a tad more via the EQ for left and right channels, The bass response from these are so good, I'm definitely sold on the passive radiator enclosure, I've even turned down the volume on the Sub (Polk MXT12), quite a lot.
Buying the Polk MXT 12 sub, in the first place, is what made me realize that, the old speakers were in fact getting tired. I've since gotten the Polk XT30 (centre speaker), I'm also going to replace the rears to Polk XT20's at a later date.
- Reviewed in the United Kingdom on 2 November 2024Size Name: MXT90BKVerified PurchaseI initially bought a pair of these to add as upfiring Atmos speakers to sit ontop of my existing floorstanders (another brand). I was quite impressed by them, but decided to wall mount them near the ceiling for a comparison... and was absolutely blown away! I was so impressed that I ordered another pair! I now have two mounted at near ceiling height at the front of the room and two in the same position at the rear. My AVR is able to change them from upfiring to height/wall mounted and they sound SO different/better.
If you can only upfire, I don't think it will disappoint you, but if you can wall mount them and have the capacity within your setup to change how they fire, then you will be blown away!
They come with a handy wall mounting guide and template which was extremely useful.

5.0 out of 5 stars Boom for the buck in a 3.1 system
Size Name: MXT15BKVerified PurchaseSelected these speakers to complete an upgraded 3.1 surround system. We have a slightly odd shaped room and wanted a very clean look with no wires. These fit perfectly in our cabinet. Together with my existing Sony receiver, 85” TV and 4K player and center speaker they are a perfect addition. Actually tried the Sony three-way speakers first, which are great speakers, but these are more appealing for what I needed. Excellent immersive sound in our 3.1 system and very nice when listening to music whether multichannel or two channel. Would recommend.

5.0 out of 5 stars Semplicemente fantastiche
Size Name: MXT15BKVerified PurchaseCercavo un paio di casse audio Monitor che non costassero molto da abbinare al mio secondo impianto HI-FI Cambridge Topaz AM5 e Topaz CD5, non conoscevo questa marca e mi sono basato su diverse recensioni sia di venditori ma anche di chi aveva già acquistato le Polk XT15 e devo dire che sono rimasto più che soddisfatto, suonano magnificamente, bassi corposi e alti superlativi, non scendo in termini tecnici perchè è già stato scritto tutto abbondantemente, le consiglio vivamente non rimarrete delusi, il prezzo è ottimo e la qualità anche!!! spedizione ottima, imballaggio perfetto.
