Sound waves emanate from a loudspeaker in much the same way as a beam of light radiates from its source. And, like the beam of light, will be reflected off nearby surfaces. These reflections can be beneficial or deleterious depending upon their intensity and time of arrival, in relation to the direct sound from the speaker. Reflections arriving too soon (early reflections) after the direct sound, confuse the ear/brain, creating chaos in the image, defocusing and confusing the three dimensional recreation we strive for.
Absorbing these harmful early reflections significantly enhances the performance of an audio reproduction system. ASC Tube Traps are an ideal way of combating these reflections, however their effectiveness depends upon accurate placement. This can be done through experimentation (trial and error), using expensive test equipment or now, with the Optical Alignment Kit.
A wide strip of reflective Mylar “tape” is temporarily attached to the wall surrounding the speakers, at ear level. Seated in your listening position, you will be surprised to see multiple reflections of each speaker, all around the room. These images represent the points along the walls at which harmful reflections will occur. Mark these points, remove the Mylar, pop a Tube Trap in each location and viola, instant gratification.
