Dome Tweeters

Dome tweeters are important for the high frequencies and transmitting a clear sound. Most tweeters are 1-inch with the range being from 0.75 inches to 1.5 inches. The Polk S30 has a 1-inch terylene high-resolution tweeter. The Polk T30 also a 1-inch tweeter that is a waveguide.

The Drivers

The drivers of a speaker help to produce the deep bass sound. Again, there are similarities in size but a little different in design. The Polk S30 has 2 5.25-inch dynamic balanced drivers that are reinforced polypropylene. The 2 5.25-inch dynamic balance drivers with the Polk T30 are bi-laminate composite.

Connectors

To connect the speakers to other devices, the Polk S30 and the Polk T30 have single gold-plated 5-way binding posts. These binding posts ensure the optimal power and sound information are transmitted to the speakers.

Efficiency/Sensitivity

Listening to anything over 85dB for a long period of time can cause damage to your ears. Nevertheless, the Polk S30 and the Polk T30 have the potential to reach 89dB and 90dB respectively.

Recommended Amplifier

There is again a slight difference in the recommended amplifier, but as with the other differences, we didn’t feel this was enough to influence our decision. The recommended amplifier for the Polk S30 is from 20-125W and for the Polk T30, 20-100W.

So, now it’s time to see how the Polk S30 and the Polk T30 are different.

Frequency Response

The higher the frequency response doesn’t necessarily make it a better speaker. We like to consider the human ear has a frequency range of approximately 20Hz to 20KHz, much further out of this range and we will struggle to hear.

Despite not having quite as wide a range, it does go a little lower from 38Hz to 24KHz.

Pros and Cons

We have included some pros and cons of the Polk S30 and the Polk T30 to help with the final decision.

Polk S30

Polk S30

Pros:

  • Excellent vocal accuracy
  • They are very durable and well built
  • Overall great sound for the price range

Cons:

  • It doesn’t produce the same sound quality for music

Polk T30

Polk T30

  • They will appeal to the audiophiles
  • Full and rich sounds
  • An absolute bargain for the price

Cons:

  • It might lack volume for some

The Final Verdict

Because the Polk S30 and the Polk T30 are center speakers, they aren’t really designed to be used alone. That’s not to say you can’t, but you won’t be able to really appreciate the bass sound of music unless you add them to other speakers. As this would then depend on the quality of your other speakers, we made our final verdict based on them being alone.

The quality of the vocals in music and movies was excellent with both the Polk S30 and the Polk T30. They were also equally easy to set up, use and felt that they were both well built. Personally, we preferred the straight edges of the Polk T30 but what made our decision was the value for money. We may have noticed a slightly superior sound with the Polk S30 but not enough to justify the price difference.
