If you are a movie buff and you can’t watch one without a proper stereo system, you should think about investing in a home theater system.

Buying from Polk Audio, you can’t go wrong. Not only do they offer a phenomenal warranty policy, but you also get a detailed user’s guide that will instruct you in easily assembling and maintaining the speakers. As for this particular set, you are getting four satellite speakers, one subwoofer, and a central channel. The two main features are the enclosed design as well as anti-diffraction, so it doesn’t come as a surprise that you will be getting high-quality sound. On the other hand, the composite driver technology ensures an always clean and powerful sound that is not common in regular home theater systems. Overall, given the features as well as the price, it is a worthy choice.

Who is this home theater system for?

If you were to ask us, this is something that any true sound or movie buff should have at their home. It is a fact that a set of speakers does take up extra space, but with the right placement, you should be able to fit these in an average-sized living room given their compact design. So if you do want your sound to have a powerful bass and excellent acoustics, this is the product for you.

What’s included?

When it comes to what’s included with this product, there are more than a few things that we are pretty happy about. Apart from the central channel and the powerful subwoofer, there are four additional satellite speakers, an owner’s manual, as well as a registration card for your warranty policy and good customer support.

Overview of features

As we mentioned above, the Polk brand is not only renowned but also features a good customer service. In case there are any built-in defects, you will not have a problem getting it replaced or repaired. One of the best things about this set is the multiple mounting options. You can also set up the speakers both horizontally and vertically.

Other than the features that we mentioned in the introductory section, you are getting an 8-inch powered subwoofer that will do a fantastic job when it comes to the bass. Looking at the performance, this home theater system will be running on a frequency response that is ranging from 40 to 22 kHz as well an impedance of 8 ohms and efficiency of 89 dB.

Along with a dynamic output of 100 watts, this creates a powerful and reliable set that you shouldn’t miss out on. Something that can be a problem is the fact that the voices are not that clear through the central channel when you are playing the audio on low volume. Other than that, and the fact that the build itself could be a bit better, it is a superb choice that any true sound enthusiast should experience.

How to set up Polk Audio RM705 5.1 Home Theater System

Using this home theater system shouldn’t be too complicated. First of all, there are multiple mounting options, as well as simply setting your speakers on ground. Just be sure to carefully read the user’s guide and search for any installation details that may affect the sound quality (including the placement of the central channel related to the subwoofer).
