The center speaker of a surround sound system is the most important. It does most of the work in the system and it is the speaker where the voices come from. For this reason, the central speaker you choose can make or break the sound quality of your setup.
Today, we are going to look at the two central speakers from Polk, the Polk CS10 vs T30. We will consider all of their features including appearance, sound quality, and value for money. Once we have compared each feature, we will put everything into a side by side chart for a quick overview. After some pros and cons of each, we will decide which of the central speakers is the better buy.
We will start by looking at what the Polk CS10 and the Polk T30 have in common.
Below you will find a comparison chart with all the specifics we have mentioned.
Central Speaker Uses
The Polk CS10 and the Polk T30, like every central speaker, won’t function independently. They are designed to be integrated into your surround sound system. With five-way binding post connectors, it is easy to set them up with the speakers you already have, regardless of the brand.
The dome tweeter of the Polk CS10 and the Polk T30 are 1-inch and made of a polymer composite. The size is standard for most speakers and the fabric allows for smooth, natural sounds.
The Polk CS10 and the Polk T30 have two drivers, one on either side of the tweeter. They are 5.25 inch with a bi-laminate composite. The drivers are both lightweight and stiff with great damping for superior efficiency. They produce an excellent bass sound and with fewer distortions.
There are no flimsy materials used with the Polk CS10 and the Polk T30. The cabinets are made from ¾-inch thick solid MDF for cleaner and more lifelike sound.
The grille, or the material on the front, is removable on both the Polk CS10 and the Polk T30. You can remove the grill if you want less muted highs. It also means that there are two design options in one.
The Polk CS10 and the Polk T30 come with a 5-year warranty on parts and labor.
The differences are quite significant, so we will compare them next.
Though similar in size, they have rather different designs.
This central speaker is 6.5 x 20 x 9.75 inches and weighs 16 pounds. It has a narrow baffle geometry design which improves the overall look and sound. You can buy it in black or cherry wood grain.
The speaker is a fraction smaller at 6.5 x 19 x 7.5 inches and weighs quite a bit less at 11.45 pounds. It comes in black.

Efficiency/ Maximum Output
Really, this relates to the maximum volume the speakers can produce. Although there is a slight difference, the 1 decibel isn’t enough for the human ear to detect a noticeable difference.
The maximum output is 91dB. This is the equivalent of power tools or a lawnmower. That might not sound loud but it is considered dangerous to listen to music for more than 30 minutes at this volume.
At 90dB, there is next to no difference in the maximum output.
The Winner Is- A Tie
