Introduction Congratulations on purchasing your Wisdom Audio SAS subwoofer. The Regenerative Transmission Line™ technology used in the SAS delivers tremendous bass performance in terms of depth, dynamics, and low distortion resulting in articulate bass that integrates seamlessly with high-resolution main speakers. About this manual 6 This manual focuses on the SAS subwoofer itself.
Description Your Wisdom Audio SAS subwoofer uses a modern implementation of an old idea for high quality, low distortion bass reproduction. While the roots of the Regenerative Transmission Line™ go back to the 1950’s, it is the combination of modern computer modeling and the vastly more powerful motors of contemporary driver design that make the RTL™ so special.
Unpacking the SAS The Wisdom Audio SAS subwoofer is a substantial piece of equipment. Please exercise caution when unpacking your SAS to ensure that you do not strain yourself from its (perhaps unexpected) weight. Caution! 8 Do not attempt to lift your SAS while bending or twisting from the waist. Use your legs for lifting, not your back. Always stand as straight as possible and keep the SAS close to your body to reduce strain on your back.
Room Acoustics & Placement Wisdom Audio believes in equalization. Assume for a moment that you had a “perfect” loudspeaker: as soon as you place it in your room, its perfection is gone. In fact, even good rooms can introduce deviations of 20 dB to the response of the system. This is particularly true in the bottom two octaves, where a subwoofer operates.
The ultimate in dedicated listening room construction involves the design and construction of floating walls, ceiling and floor. This approach yields the added benefit (when done properly) of providing outstanding acoustic isolation from adjacent spaces as well as superb bass reproduction. This approach goes well beyond the scope of an owner’s manual; if you are interested, you should contact a professional acoustician who has specialized in this sort of domestic room design.
a center image where it belongs. f course, if people are sitting well off to one side in the room, the image tends to fall into the nearest speaker. Failing an acoustically transparent screen or a phantom center channel approach, the important thing is to match the tonal and dynamic capabilities of the Left and Right speakers while minimizing the change in image height as a sound is panned across the front stage.
most likely to suffer from the response irregularities introduced by the room itself, operating as they do below approximately 80 Hz in most systems. Recent research into the behavior of rooms as a function of speaker placement has concluded that — if you have the freedom to do so — there are significant advantages to placing several smaller subwoofers around the room, rather than relying on a single large woofer.
ditoriums, lobbies in commercial buildings, etc. The problems seen in “small” rooms (residential spaces) are quite different, and outside the experience of most acousticians. Find someone who specializes in and has a great deal of experience designing home studios, home theaters, and the like. Your Wisdom Audio dealer may be such a person; failing that, he/she can help you find such a professional. References Books on Acoustics: The Master Handbook of Acoustics, F.
Connections 1. Speaker Terminals Connect the + and – terminals of the power amplifier that is driving the SAS to the corresponding + and – terminals of the SAS, located in the recessed input cup. Note that while Wisdom Audio amplifiers are all non-inverting, some other brands of power amplifiers do invert polarity.
Setting Up the SAS The unusual form factor of the SAS allows it to be used effectively in many situations where a more conventional “bass cube” would be either cumbersome or impossible. Examples include locating it behind a couch, in the small space between the couch and the wall, or laying flat under a set of risers in a home theater with multiple rows of seating. The SAS also includes two locations for the exit of the Regenerative Transmission Line™.
