Let’s find out…

Both speakers have the same size drivers and tweeters. You can find more about these drivers and their sizes below.

The t30 is slightly smaller and more compact, while the CS10 is a bit larger.

Both have the same height of 6.5inch or 16.51cm, but the T30 has a width of 19″ (48.26 cm) and 8.5″ (21.59 cm) height, whereas the CS10 has a width of 20″ (50.8 cm) and 6.5″ (16.51 cm) height. The Polk CS10 weighs 16 lbs (7.26 kg), and the T30 weighs 11.45 lbs (5.19 kg).

Regarding build quality, both speakers are well-made and feel solid and durable. Both are made of MDF wood, a high-quality material that helps minimize resonance. There are no cheap plastic parts or anything that feels flimsy.

In design and build quality, there is only one noticeable difference which is the angled top.

The Polk CS10 has an angled top that allows you to place the speaker in a different position, like you can place the speaker below the TV yet direct sound towards the listening area. The T30 doesn’t have this feature, it has a flat top, but it’s not a deal-breaker.

Overall, both speakers have great design and build quality. The Polk CS10 has a slight edge due to its angled top.

First, let’s find out the spec of both speakers, including the driver sizes, frequency response, and sensitivity, and then we can start talking about the actual sound quality.

On both speakers’ front, as the grille will be removed, you’ll see the two main drivers with one tweeter on both speakers. Polk CS10 and Polk T30 have a 1-inch silk dome tweeter and two 5.25-inch Mid/woofers.

The Polk CS10 has a slight edge in the bass department due to its higher power handling capacity and slightly higher sensitivity. The difference is unnoticeable, and the bass is not booming or too much; it’s just perfect. Both speakers have a very good bass response, and you won’t be disappointed with either one.
