## Customer Reviews

### ⭐⭐⭐⭐⭐ Awsome speakers
*by S***Y on 11 February 2024*

With the right settings the Polk XT 60 delivers excellent performance and sound quality. Highly recommended and absolutely value for money.

### ⭐ Low quality
*by K***K on 18 April 2026*

I don't hear anything from this speaker

### ⭐⭐⭐⭐⭐ Sounds great, but the measurements are inaccurate.
*by L***P on 4 July 2026*

I got the XT30 to team up with a pair of XT70s. The design is basic (not really an issue if it's concealed), but dialogue is clear and crisp. Great performance for the price. And if you can, take the cover off to show a bit of color. A big downside is Polk's deceptive or inaccurate measurements. They claim the Dynamic Balance woofers are 5.25 inches. That's inaccurate. It's only 5 inches from one edge of the FRAME to the other. The speaker itself is a smidgen under 4.5 inches from the outer edge of the rubber to the other. So be aware of that when considering buying this speaker. I'll give 5 stars for performance, but the basic design and inaccurate measurements are red flags to me.
