We all know how popular Logitech is. It provides both the 5.1 surround sound and Dolby surround. But, the Logitech subwoofer may stop functioning. So, you should keep this in mind. Nevertheless, it is a very reliable brand.

So, without further ado, let’s start with the head-to-head comparison.

Features

One of the core competencies of any sound system is its features. From dynamic range of sound to giving real-life feeling, this thing matters the most.

Dolby surround can provide the best output with only 3 speakers. Combined with Dolby Atmos, it can provide a 360° artificial sound. Also, it can reduce noise using the same software. But, it also faces issues like noise distortion, lag, jitter, etc.

On the other hand, 5.1 surround sound has more speakers. The dynamic range, technology, realistic sounding, etc. will be top-notch and better than Dolby surround. However, it isn’t supported by Dolby Atmos.

Summary: With Dolby Surround, you have better software support. But you get better hardware support with 5.1 surround sound.

Channels

The channels of any sound system refer to how many audio outputs are available. It can give you a whole new experience with music, movies, audio podcasts, etc.

Dolby surround outputs are in total 3. This includes 1 subwoofer and 2 standard speakers. You get sound coming from the front 2 speakers and depth effect from the subwoofer.

Nevertheless, 5.1 surround sound outputs are in total 5. This includes 1 subwoofer and 2 standard speakers, which is more than Dolby surround. So, the dynamic range of audio and audio depth is more than Dolby surround.

The sound quality largely depends on the audio format. However, it also depends on the audio sample rate.

Now, Dolby surround supports Dolby digital 3.0. The file format for this is AC-3. The sample rate of this sort of file is up to 48Khz. So, the audio quality won’t drop as it can convert audio files efficiently.

Yet, 5.1 surround sound supports Dolby digital live. The sample rate of this is 44.1 Khz to 192 Khz. It can work more efficiently than Dolby surround. So, the audio quality is better for 5.1 surround sound.

Nevertheless, Dolby surround sound system has high-quality audio too. But, compared to Dolby digital live, it is slightly backdated.
