4. LLC Appendix A Why EQ Despite efforts by speaker designers to provide a specific type of frequency response for their products the environment in which they are tested is typically anechoic a room designed to absorb sound and eliminate reflec tive effects or quasi anechoic ground plane This test environment removes the acoustic effects of the listening room and allows the designer to specifically tailor the characteristics of the speaker to a desired set of criteria In many but not all cases the designer will try and achieve a flat response e g very close to the same energy produced at all frequencies covered by the speaker The attached graph shows a plot of sound energy of a flat subwoofer in an quasi anechoic environment LMS unero FIG 20 Subwoofer Response in a Quasi Anechoic Environment When a speaker or subwoofer is then placed in a non anechoic environment read our listening rooms and Home Theaters the frequency response of the speaker subwoofer is rarely close to that measured in the anechoic environment due to the reflection and absorption of sound waves off of hard and soft surfaces This in turn causes positive and negative reinforcement of sound energy and as such the sound that then reaches our ears may seem overly loud in some frequencies and muted in others and definitely different than what the speaker designer and recording engineer intended The attached graph is an example of the ef
