Excellent Quality For The Price.
These 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.

Well worth buying, but are sold separately, not in pairs
I 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.

I finally got to set up the speakers after they arrived a long while back. Delivery was quick, items arrived in perfect condition. Set up. Was a breeze, Im using a Yamaha AVR. The sound is very good and the asthetics to match. The front mesh serves as a good barrier but unlike to see the drivers as they push they move the air. It’s sounds really good, I highly recommend these speakers especially if you watch movies. It was a good buy.

These speakers actually work with Atmos and anything that needs height effects. I used to have some onkyo ones but removed them as they did nothing. I can only comment on these speakers being used as height speakers but I am delighted with these. The sound quality is really good but I have to mention the build quality is amazing. I had an accident when putting these up and one fell from around 10 feetð¥ I was certain they were going to be broken but asides from some exterior cosmetic damage the speaker is working fine ð

I have been building a home system for the past couple of years with both new items when on sale from different sources and old speakers bought off of Marketplace all connected to a 7.2 Pioneer VSX 932 amp. With the exception of my 4 side and back speakers they are all Polk who has an awesome rep for being top end speakers! I bought this one to replace my CS 100 Polk speaker that I bought for $40 off the net and it sounded good. I bought this new Polk to replace it as Xmas gift to myself and it does not disappoint! Amazing sound quality and clear crisp voice sound from the speaker. I love the Atmos effect sound feature that I was looking for. I was looking for Atmos Height speakers to add on to the fronts but this idea works betterâ¦One of the reviews stated the unit was plastic but mine is solid and heavy wood which I am very pleased as a plastic box would lower the standards! I paid $500 for this speaker and thatâs a lot but I am very happy with the sound coming out of it. Itâs a good addition to my home system. I donât see any good Polk surround speakers but my side and back Bose 101âs sounds amazing and they are small so not visible in my living room set up as hidden in the many plants my wife has!The only complain I have is the posts are too close together. I have big fingers and getting the wires around the bottom of the posts and holding them in place while tightening the posts is a challenge! The wires came off a few times till I finally got the post tight! I plan on using banana plugs if I can find them in my houseâ¦Overall excellent sounding speakers that will make any buyer happy watching any type of media from TV, to DVD, to B

The speakers perform really well and Iâm very happy to finally be watching movies in Dolby Atmos. But, I really want to commend Polkâs customer service. I purchased these speakers in Feb of 2025. They worked great until a couple of months later one of them developed a slight hissing sound. So I called Polk customer service and immediately spoke to an advisor. She dismissed the issue as a driver problem and said they would send me a new one. So on Wednesday May 28th I first called Polk and by Monday June 2, had the new driver in my home. It was an easy install and it sounds great. I am a big fan of Polk speakers. Give them a try.
