Polk t15: The absolute epitome of good value

The Polk Audio t15 speakers are perfectly viable as a pair of bookshelf speakers in the best quality on a budget. These excellent audio speakers deliver a substantial audio experience with delicacy and class.

Design and feature overview

These vented two-way speakers come in the color black, giving it a minimal and appealing vibe. The Polk t15 is composed of a half-inch MDF in combination with a wood grain texture surrounded by vinyl. It features a polymer composite dome tweeter and cone woofer, both of which are equipped with the Dynamic Balance technology.

Sound Overview

With Polk Audio’s unique Dynamic Balance Drivers and tweeters for wide response and low distortion, the Polk Audio T15s are a group of stereo speakers that deliver incredibly clear ambient soundscapes.

It is equipped with rubber driver sounds that improve both frequency response and durability. To reduce any static distortion, these audio active speakers are designed with magnetic shielding. The overall sound produced by the bookshelf speakers is warm, loud, and with minimal distortion.

Polk tsi100: Modern and effective

The Polk Audio tsi100 offers an elegant exterior combined with an impressive performance that exhibits clean high frequencies and midrange thanks to its unique technologies such as dynamic balance drivers and flared ports. To enjoy an open soundstage with accurate imaging, the Polk tsi100 should definitely be a worthy addition to your sound system.

Design and feature overview

The Polk audio tsi100 comes in two finishes: black and cherry, each design has its unique style. Because of their compact nature, these bookshelf speakers are very convenient to use and set up.

Apart from its appealing exterior, the design features low-frequency drivers and high-frequency tweeters to complement the sound. The silk dome tweeter is built from polycarbonate of exceptional quality which helps to deliver accurate response without distorting the sound.

Sound Overview

The speakers perform quite well overall- with balanced, crisp, and enjoyable sound. However, the tsi100 excels in the treble performance with remarkable clarity in tone and perfect precision.

Analyze Comparison: Polk t15 vs tsi100

Sensitivity

The sensitivity of an audio device tests the capacity of the speaker to translate volume into electricity and it is measured in decibels (dB). To attain greater volumes, reduced sensitivity speakers need more power from the amplifier, whereas higher sensitivity demands less power.

Hence speakers with greater sensitivity are louder. Usually, any ranking of sensitivity up to 88 dB is lower. The Polk active speakers, therefore do not have much sensitivity and require more power to achieve high volumes.

Peak power

Peak power measures the maximum power handling capacity of the speaker, that is- it is the maximum wattage a speaker can accept from an amplifier before it burns out. The Polk audio shelf speakers both have a peak power of 100 Watts, which may not be that sufficient. Usually, 300 Watts is considered a good power rating.

Midranges

Speakers with midrange drivers allow tweeters and woofers to focus on the sound waves they’re best equipped to produce, thus creating a sound that is more accurate. T15 and tsi100 both, however, do not have midrange drivers.

Impedance

The impedance indicates the electrical resistance provided by the speaker to the power signal by an amplifier. The lower the impedance, the more powerful an amplifier is required to achieve a higher volume of sound. Usually, the most common impedance rating is at 8 ohms, as seen with the Polk t15 and the Polk tsi100, because it works with most of the amplifiers out there.

Physical features

The most obvious difference among the Polk brothers is its physical design. Since it is slimmer, Polk t15 has a much smaller surface area than Polk tsi100. But perhaps because of its height, some more headroom is required.

The Polk tsi100 is, on the other hand, a very fat, thick, and short speaker. But in general, these two audio boxes are small and lightweight. You should be able to comfortably place them on a desk or a shelf.

The Polk t15 is only available in black, while the Polk tsi100 is available in black and cherry.

Tweeter

The tweeters, which are located at the top of the speakers, produced the highest frequencies in the sound. This frequency is usually about 2000 Hertz. Tweeters can come in different shapes and sizes, the former being more crucial in determining the quality of sound.

Usually, a larger tweeter is louder than a smaller one since it is able to disperse sound over a large surface area. If we compare the tweeter size of the two better quality bookshelf speakers, the Polk tsi100 which is 0.6 cm larger in size than its competitor Polk t15, is definitely at an advantage.

Tweeters can come in four different shapes including: cone, dome, horn, and planar magnetic. The Polk audio t15 and tsi100 have dome-shaped tweeters, which provides the advantage of dispersing the sound across a larger area.

In addition to all these features, the material that the tweeter has been constructed with has a significant impact on how its sound will be emitted. The Polk t15 uses a soft silk composite dome which is mounted in a shallow waveguide.

Whilst the advantage of this is that this composition produces a more natural tonality in sound, it fails to handle enough power. This has been solved in the other model. The Polk tsi100 has what is called “Dynamic Balance” technology instilled in its dome composition, which helps amalgamate materials of highly different resonant behavior so that they damp each other’s resonances for an overall low-resonant composite.

Winner: In terms of tweeter construction, size, and shape it is no doubt that the Polk tsi100 performs better.

Woofer

The role of the woofer is quite simple- it provides low-frequency sounds and bass. Usually, the bigger a woofer the louder it is. Whilst the woofer size is the same for both the speakers, the material is where it sets them apart.

Woofers can be made from a variety of materials ranging from polypropylene, paper, Kevlar to metal. The ts15 woofer is a Dynamic Balance mineral-filled polymer composite cone driver. The motor section of the woofer is composed of aluminum, which is good for thermal conduction. On the other hand, the tsi100 is composed of bi-laminate organic fiber.

Frequency response

The range of sound a speaker can produce is depicted as the frequency response. Usually, a good frequency response starts at 50 Hz or lower and covers as much of that range as possible.

Winner: When compared, Polk audio t15 seems to cover a wider frequency range at 60 Hz-24 kHz than its competitor Polk audio tsi100, which covers a frequency response of 53 Hz-25 kHz.

Magnetic Shielding

When sound is played through a speaker, an electromagnet is activated using the power from the amplifier to bring the driver forward, and another magnet pulls the driver back. This causes the driver to move forward and backward rapidly to create sound. Because of this process, speakers create an electromagnetic field that can cause serious problems for other devices.

Winner: Among the comparison of t15 vs tsi100, Polk audio t15 has the added advantage of magnetic shielding, proving to be the better competitor of the two.

Connections

Wireless speaker setups do not need a speaker wire or direct lines to other speakers and the AV receiver and have both their ups and downs. These speakers are not completely wireless through- you’ll still need to plug them into AC outlets for power.

Wireless speakers are typically more expensive. Moreover, there have been complaints of the sound quality being drowning out by the wireless feature by many users. Whilst the Polk audio tsi100 is had a wireless connection, the ts15 bookshelf speaker does not have that feature.

Winner: However, the Polk audio t15 has many other connection points that are lacking in the Polk audio tsi100. Binding ports, speaker wires, and banana plugs are just a few of them.

Price

The price of Polk audio t15 is lower than Polk audio tsi100. Hence if you’re on a budget, the Polk t15 should be your ultimate savior.

What should you look for in a speaker?

Before buying a bookshelf speaker, there are certain aspects that you have to keep in mind. Here are some of the features that should help you better decide which speaker to get.

Speaker size

Usually, people have the misconception of “the bigger the better.” Just because a speaker might be bigger in size, does not necessarily mean that it performs better in terms of sound. Moreover, smaller bookshelf speakers are much more convenient to move and set up than bigger ones and they also take up less space.

Sensitivity and Volume

Any reading of sensitivity below 86 dB is often considered to be low and it is advised that for better performing speakers, you should choose ones that have the sensitivity in the range 87 to 95 dB. The higher the sensitivity, the louder will the speaker sound.

Wired vs Wireless speaker

Generally, wireless speakers are more convenient than wired speakers and have more connectivity options. However, some say that wired speakers perform better in terms of sound. But this certainly varies from speaker to speaker.

Sound quality

With the compactness in size, bookshelf speakers have a limited number of drivers which may be a concern for the quality of sound being produced. However, some bookshelf speakers have excellent technology incorporated in their design that helps them to perform meticulously. Hence, before getting any speakers a background check is essential to be made.
