Head to Head Comparison
This is where things get interesting and confusing. But don’t get perplexed. I will provide what each sound system will offer in a simple manner.
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.
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.
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.
Summary: 5.1 surround sound provides more channels than Dolby Surround.
An amplifier is an essential device to provide enough gain to power up your speakers. If you’re in search of some quality amplifiers for your surround sound, try these out:
These amplifiers have Bluetooth features. So you can get more ease in using them without needing any wires or cables.
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.
Summary: 5.1 surround sound has better audio quality than Dolby surround.
We expect that any sound system will cover our expected area. So, let’s see what each surround sound system has to offer.
Dolby surround is perfect for a small to medium room. It can cover every bit and provide a loud sound too.
However, 5.1 surround sound is perfect for medium to a large room. So, it has a larger coverage area than Dolby surround. Also, 5.1 surround sound has a better audio focus than Dolby surround. Because 5 devices can confine the audio well than 3 outputs.
Summary: 5.1 surround sound has a larger coverage area than Dolby surround.
Surround sound system is widely used in many things. So, let’s see what devices are supported.
Dolby surround can be used in almost every old and new technology. Mostly, it is integrated. But, you can also add external speakers to use the feature.
However, 5.1 surround sound is widely used in cinema halls, home theaters, and games. The 5.1 surround sound system was used in 1975 in the movie “Tommy”. Since then, it is widely used almost everywhere.
