Polk S20 is undoubtedly the best speaker in this series and also compared to other competitors. It brings a new home theater experience that can take your movie experience to the next level like you are sitting in a movie theater.
For music lovers, it can give the most realistic tone ever you would feel that you hearing the original content. In the loudest music, you feel a concert feeling just as the artist is standing right before you.
All thanks to Polk’s advanced technology and hard work. Admittedly, it is rich with many high features but what you can find new in it is the Polk patented Power Port technology.
This feature was absent in the Polk S10 and Polk S15, and most probably Power Port tech makes it the best choice ever. All music lovers or movie lovers become concerned about the bass or the low frequency.
Polk resolves this problem by introducing this technology. Any bass lover like me will definitely become surprised after having this feature in their speaker. This tech just ensures a smooth airflow between the speaker and you; which directly hit the ears.
You can feel the hard punch of bass in your ears so you can enjoy your movie or music with full thrill. This minimizes the distortion as much as possible and honestly, if you are not a sound expert you won’t be able to catch the distortion at all.
Besides, there are the mica reinforced polypropylene cones surrounded by butyl rubber. For the dynamic bass, this woofer has also the core role. The material is excellent the size is praised can crack to any low frequency precisely.
The tweeter is also great contains a ceramic motor structure. It is made with Terylene and Conex fiber spiders. This helps to stay at a balanced temperature and these materials can bear high temperatures so no worry about the damage.
If you want your speaker to provide both high and low frequency clearly then focus on the material along with the size. Polk S20 is rich on both sides that make it perfect for TV, home theater, or other purposes.
The design is coming with is like the S10 and S20 but you can the bigger version of them. The black finish is matte and beautiful. There is an anti-diffraction, magnetic grill you can attach or remove.
The modern MDF cabinet with round edges enhances the beauty. Like I have always said this kind of design compliments any room decor. But seeing the sound quality and features it is recommended to use this speaker in big rooms to get the full speaker experience.
Much bigger and improve sound and bass compared to S10 and S15. Suited for big rooms and can be the best companion of the home theater system.
Polk S10 VS S15 VS S20: Detailed Comparison
There are very few comparisons between Polk S10 VS S15 VS S20. But this slight difference has a great impact on the sound quality. So, this section is going to help you figure out what type of sound you want.
Also, will help you understand some basic information about the sound quality how can you measure it. Without an expert, you can find the best speaker for you.
High-quality Tweeter For Great High-Frequency Response
Tweeters or drivers are an important part of a speaker, as only they can produce an efficient high-frequency response. All three Polk Signature series speakers have the same 1’’ Terylene dome tweeter.
This extends the low resonance and a dynamic sound stage. Every good brand becomes concerned with the high-frequency response. So, they try to get the best material and 1’’ is a size.
All their speakers here produces the right amount of frequency response. So, here the actual difference is not noticeable. But this is for sure that you won’t be disappointed about the tweeter performance.
Here comes the best part of a speaker and the most worrying matter for the bass lovers. A woofer is the only equipment in a speaker that produces the low frequencies that means the bass.
Punchy and powerful bass can change the movie or music experience totally. In every scene dramatic or romantic the punch of sound can turn the scene into the real one. S10 has an average woofer, but S15 and S20 come with a bigger woofer version. Like the woofer, several features have been updated, but each of them is worth praising for sure.
The material and the size are the big facts in a woofer. All three speakers have the same material woofer but the difference is visible in the sizes. And this makes a huge difference in the quality of the sound.
Polk S10 has a 4″ mica-reinforced polypropylene Dynamic Balance® cone driver. Polypropylene is a kind of cone material that the renowned brand Klipsch uses frequently. You can think of its great performance.
Then comes the size. Honestly speaking 4’’ woofer size is not enough for giving a powerful hit of bass. It can work on an average scale but cannot reach a high level.
If we compare it with others then 4’’ is not gonna work. But instead of comparing if we measure the performance of this alone then definitely this is a decent quality speaker.
Then talking about Polk S15, it has a bit big woofer that is 5.25’’. Most of the speakers contain this size woofer that is decent and can give a slight punch of bass but not the deepest form of bass you can expect from it.
But as S10 had a small size woofer that kind of woofer is good for a small size room. But Polk S15 can be suitable for medium or big rooms. It can fill the room with amazing sounds.
Also, another thing to be noted is that the tweeter is the same for all three speakers but that combines with the woofer, which affects the audio quality. They work together and give a beautiful balance dynamic high and low frequency.
The beautiful result is lifelike music or audio content you can enjoy.
The same thing is for S20. But this speaker gives the most precise and splendid quality sound because it has the biggest woofer among the two others.
6.5’’ woofer can give a wall-shaking performance. Any form of audio whether it can a piece of soft music or jazz, rock or other every beat you can catch like the heart pumping.
Your wall would start shaking literally. This speaker gives a tough competition to another high-quality speaker mostly because of the big woofer.
Winner: The winner is clearly S20. But the rest of the speakers also have a balance woofer and low-frequency performance according to their mechanism.
Perfect frequency response can enhance the whole sound quality but an imbalance frequency response can destroy the whole thing in a minute. This is why it is necessary to check the frequency response.
A frequency range of 50 Hz or below is the best for the defined and clear audio. This rate differs from speaker to speaker according to their other criteria price range.
Polk S10 has a range between 67-40,000 Hz, which again couldn’t satisfy its consumer totally. But admittedly this range is good enough. The reason is in the price range if you see other speakers then you can notice they have a much higher frequency range which makes the sound quality a total disaster.
But Polk improved this feature in S15 by converting the range between 50-40,000 Hz. This can be taken as a good frequency as 50 Hz is a human ear audible. That’s why under this every audio hears clear.
But is Polk S20 is best in every criterion as it has every updated feature than S10 and S15, the frequency response is 39-40,000 Hz.
With the impressive tweeter, 6.5 woofers, and this frequency you can expect to hear every word from your TV happen to be real. If you have a 4K or high-resolution TV then be ready for the lifelike and real movie experience ever.
What you are going to hear you would feel all things are happening around you.
Good RMS Power Handling Capacity Has A Good Effect On Sound
The RMS power of peak power is another factor that works behind the good sound. For smooth performance, a sufficient amount of power is needed.
Both S10 and S15 have 20-100 power handling capacity. For the S10, this amount is good but as S15 has some updated features and the performance has updated too bit more, RMS may enhance the performance.
Apart from these two speakers, the S20 has up to 125-watt power. For handling the high-end performance, detailed sound in the loudest form is not a tough task for it in 125 watts.
Which has the best sound quality?
You have already figured out which one is the ultimate winner between Polk S10 VS S15 VS S20. Yet some criteria are left behind to discuss.
The impedance and the sensitivity rate decide the loudness and the ancientness in a speaker. All three speakers have the same 8-ohm impedance. This is perfect and no argument about this fact.
The question is now about the sensitivity rate. A sensitivity rate above 80 dB is considered the loudest. S10 VS S15 VS S20 have this rate 87 dB, 88 dB, 88 dB respectively.
Therefore, which speaker you choose your room or home is going to shake. Even this may disturb your roommates or housemates. For the rock type music lover or those who love concert can have a live concert in your home now.
Polk S10 has all the decent features, and the sound is perfect for TV shows, movies, or music. But we won’t recommend this speaker as a part of the home theater.
But Polk S15 and S20 can be a good choice for both movies or home theater. Now if you want to know which is the best then of course it would be Polk S20. It has the amazing sound quality ever.
This is the ultimate winner and the best speaker of the Signature series. But the price may seem a bit for some but trust me actually they are offering a much affordable speaker.
