This is the first in a multipart series showing simple techniques for analyzing and determining how various subwoofer arrays will cover and sound. In this and future videos you will see the issues with sub coverage and sound quality and learn some ways to improve.

$How Real Do the Drums Sound? In this YouTube video, Dave Rat talks about a method of achieving realism in reproduced sound rather than just fidelity. He discusses the flaws inherent in conventional sound systems and recommends placing the sound source directly in the listeners acoustic environment for a more realistic experience. He then goes on to demonstrate the difference between different speakers and encourages users to acquire the tools that will achieve their desired outcome. Ultimately, he describes a method to create a sound that is realistic and not just a reproduction. 00:00:00 In this section of the video, the speaker demonstrates how conventional sound systems are designed to recreate an audio environment and bring the listener into that space, but its not entirely realistic due to the physical world we live in with regards to distance and time it takes for sound to travel. Instead, the speaker lays out a different approach where the instrument, such as a guitar player, is placed directly in the listeners acoustic environment to create a more realistic scenario. The speaker also notes that audiophile sound systems are not based purely in science but are rather an art form wrapped in science, though there is science involved and audiophile speakers can still sound wonderful. 00:05:00 In this section, the speaker recommends purchasing speakers based on personal preferences for aesthetics, practicality, or sound quality. He suggests buying speakers that were used during the recording or mixing process if one wants a sound system that sounds closest to how it was intended. However, he notes that realism in sound reproduction is not the same as identical recreation or fidelity, and there are many factors that contribute to how we perceive sound. Ultimately, one should acquire the tools that will achieve their desired outcome. 00:10:00 In this section, the speaker discusses the importance of realism in reproduced sound, as opposed to just fidelity. Realism means that a sound source will sound real regardless of where you are in relation to it. The concept of a sweet spot, where the sound is best, is a result of flawed sound reproduction systems. The speaker then goes on to demo a homemade four channel, four signal speaker compared to a pair of vintage speakers using higher quality gear. He cautions listeners that the speaker may not be suitable for their specific application, but that it creates a realistic sound of a drummer in the living room. 00:15:00 In this section, a raw drum recording is played back through different speakers, including the real speaker without the sub, the stereo speakers, and the real speaker with the sub. The goal is to determine which sounds more realistic, not necessarily what sounds better or smoother. The platform from which sound is projected is crucial to creating sonic realism, and speakers that radiate all sound in one direction or a single sound in multiple directions are incapable of reproducing realistic sound. The fundamental platform is what determines the sounds realism, and once that is established, the sound can be refined. 00:20:00 In this section of the video, the speaker expresses their fascination with creating and reproducing realistic sound through instruments. They are impressed with how effective and simple it is to make something sound real, even though the YouTube format can only capture a fraction of the full realism. The speaker notes that the difference between formats can be heard, and signs off with a reference to Spicoli McConaughey.
