If you are looking for a center channel for your home theater system, then it is highly likely that you still do not have external processors or other stereos. The reason behind this conclusion is the fact that in building a home theater system, either the sound bar or the center channel speakers are the first units to be bought.

With that said, the center channel speaker should be compatible with the other speakers that you are going to purchase. More than that, if you are slowly but surely setting up your home theater system, it is also possible that you will be utilizing the center channel speaker for a long time before you go ahead and set up external speakers.

With that in mind, the center channel speaker is crucial, so you should always go for high-quality ones. In this review, we are going to talk about the Polk Audio Blackstone TL1 Speaker Center Channel to determine if this is a cut above the rest.

Polk Audio Blackstone TL1 Speaker Center Channel Review

This unit was made to be just like any large home theater system while still maintaining a compact design.


This unit has two 2.5-inch drivers, injection molded cones, and a 0.5-inch silk dome tweeter. A periodic-tuned rear port is also included. This is responsible for delivering the bass extension as well as boosting the audio when it is mounted on the wall or a shelf.

Additionally, it has a unique curved design which was inspired by time lens technology. This design paves the way for the proper alignment of the acoustic center of the tweeter.

The mid-bass will also be aligned in the same plane which results in reducing distortions and diffractions. It will also make sure that the right sounds will reach you all at the same time. Another good thing to note is the fact that this unit was designed to be built upon.

Therefore, you can have a 7.1, 6.1, or 5.1 home theater system. Based on the size of your room and other requirements, you can add four or even eight satellite speakers to this center channel. If you really want a boost, you can also add a subwoofer.

Moreover, you do not have to worry about pairing it with other components because it can easily connect to a receiver just like a normal speaker. As for its performance, it has a smooth low-end acoustic suspension enclosure which can control the air flow in the port which results in gentle bass response. There is also the blending of the subwoofer and the speaker.

Further, there are smooth highs and pinpoint imaging. Lastly, the audible coloration is lessened from the resonances of internal surfaces.


The Polk Audio Blackstone TL1 Speaker Center Channel is a small center channel speaker that performs just like any other completely set up home theater system. Its audio technology is advanced in such a way that you can clearly hear lows and the highs will not pierce your ears.

The output is also resounding that it fills a decently sized living room with a rich and warm sound. Also, you can mix and match different components with this unit as it can be easily paired via the receiver.

Set up is also straightforward and it comes with ports that are great for neat cable management. If you are someone who loves bass, this center channel speaker can manage the distortion properly just as long as it is not too consistent.

That is something you should take note of as its enclosure was not designed to withstand such torture. But for regular movies with distant ins and outs of sound, your listening experience is going to be flawless.

Comparison with the Polk Audio CS1 Series II Center Channel Speaker

Let us now compare the Polk Audio Blackstone TL1 Speaker Center Channel with yet another center channel speaker with the same brand which is the Polk Audio CS1 Series II Center Channel Speaker.

The latter has two 5 1/4 inches dynamic balance woofers and a one-inch tweeter which is great for high-frequency responses and accurate reproduction of audio with low distortion. It was also designed to have a powerful center because the port at the rear of the speaker can deliver powerful and deep bass.

Therefore, even though you are listening to a piece of high impact music, it will still sound very lifelike and natural. It also has a unique design because it is reversible. Meaning you can place the loudspeaker below your ear level and you can still hear clear and crisp sounds.

Also, you can turn it upside down so that the sound is aimed upwards which is directed straight to your listening level. This can also be paired with a monitor with 60 or 70 tower speakers if you have a large room. Then if you are going to use this as bookshelf speakers, you can use a monitor with 40 tower speakers.

In summary, the Polk Audio CS1 Series II Center Channel Speaker is a good option if you are after clean and crisp sound not only for home theater but also for music.


The Polk Audio Blackstone TL1 Speaker Center Channel is still the better option if you are going to set up a home theater system. The other unit is better when it comes to just listening to music.

The former was also made to be used on its own so even if you still do not have external speakers, it is as if you already have a complete home theater system. Keep in mind that you can have that semi-surround sound if the room is not that large.

You can expect clean sounds with managed distortion. As for high sounds with higher frequency, the center channel speaker alone cannot properly produce it, but still, there will be traces of that sound. Other than that, you will not encounter any audio problems with this unit.
