Polk S30 vs S35 | Sound Quality

Sound quality is an immense responsibility of a speaker. Because it is the main work the speaker needs to provide. Before comparing the sound quality, some points need to be compared first.

Like the frequency response, sensitivity, drivers, etc. These things make the audio quality define.

Polk S30 vs S35 | Frequency Response

With Polk S30, you could note a difference in the lower frequencies that isn’t present in Polk S35.

Frequency response makes a huge difference in the sound quality. The excellent frequency response can produce more fantastic sound. It refers to the musical tone that the speaker can produce.

So, a decent rate is a must for getting the higher sound quality. The more the sound quality becomes high, the more detailed the movies or music. Even the frequency range has a significant impact on other features like sensitivity rate or others.

All these make a combination for making the sound incredible. Polk S30 has a frequency response of 42-20k Hz. Another hand Polk S35 has 53-40k Hz.

Comparing both of them with other features, the Polk S30 can work better than the Polk S35. Polk S30 will deliver fine-tune, significant frequencies for unique sound production. The vocals will hear so rich, crisp, and clean that every word will be heard in detail.

At the same time, Polk S35 also has a decent amount of frequency rate. But the fact is if the first number in a frequency range is low, then it means the most resonant bass. So, if comparing the S30 is better.

But for a comprehensive overview, S35 also works amazingly. Setting up with home theater the fullest frequencies you can get.

Winner: Polk S30

Polk S30 vs S35 | Sensitivity

The small difference in sensitivity between two speakers doesn’t matter all that much.

To see the sensitivity rate is another critical area that most people ignore. Because if your speaker doesn’t provide a decent sensitivity rate, you can not expect a louder sound.

Sometimes our speakers need to be too loud to listen to some jazz or rock type music. Even in movies or content, there are many scenes those need to be too loud and energetic.

As the center channel speaker makes every word hear realistic, the sensitivity rate is also necessary. When we come to see the features, it is clear that S30 has a higher sensitivity rate than S35.

The rate is 89 dB and 88 dB for S30 and S35, respectively. However, the difference here is not huge. But with another tech like frequency response or impedance, it has a significant impact on the whole sound system.

It’s clear if you choose Signature S30, your possibility of getting the louder speaker becomes high. But at this, S35 also a powerful speaker. But the best would be if they contain over 90 dB because the speaker becomes the loudest one at this rate.

Winner: Tie

Polk S30 vs S35 | Impedance

Both speakers have the same impedance of 8 ohm.

Impedance does not have a significant effect on sound quality. But while choosing the speaker, the impedance should be noticed. Because it is closely related to power consumption.

Lower impedance is suitable for speakers as it means how to power your speakers. The less efficient the work would be going on. 

But here is nothing compared because the impedance is the same 8 ohm for both speakers, Polk S30 vs Polk S35. So, they both will consume power in the same way. Here is an Impedance Guide for Speakers for you to understand the whole process.

Polk S30 vs S35 | Tweeter And Driver

Polk S35 has six 3-inch dynamic mica reinforced polypropylene drivers instead of two, while S30 has two 5.25-inch dynamic balance mica reinforced polypropylene drivers.

Good tweeters and drivers are the foremost for the excellent sounding system. And this Signature series of Polk did impressive work while making the equipment.

They did not compromise whether it makes them with high material and thus an impressive sound they can produce.

Both Polk S30 vs S35 has a 1-inch tweeter, which has a good shape. They are made with soft-dome, Terylene, and have a High-Res dome. This gives a typical high-frequency range and sound spacious.

Going towards the drivers, Polk makes speechless by adding these incredible drivers into their center channel speakers. Too much low distortion, clear-clean deep bass with efficiency in work the drivers are capable of giving.

The drivers are made of Mica-reinforced polypropylene cones along with butyl rubber surrounds. They are adding high-temperature Cones fiber spiders and a massive structure of the ceramic motor. All these come combined and work together smoothly and nicely that the sound becomes so big and reliable.

As a result, it’s obvious that both speakers use the same form of drivers in order to achieve high-quality sound. However, the scale and number of people here is significant.

Polk S30 has two 5.25-inch drivers. Polk S35, on the other hand, has three 3-inch drivers. And if you’re familiar with audio devices, you’re also aware that a large woofer translates to a large sound blast.

The more powerful the woofer, the more dramatic the tone. As a result, the obvious winner is Polk S30. However, if you want more drivers, the S35 is a good option. For the extra drivers, I’d go for S35.

Though the price range is a bit high, if you can afford that and want some breathtaking performance, then go for it. That won’t make you regret it for sure. And if you’re willing to give Studio Monitors chances, try these 2 Polk Audio Monitors
