Introduction Congratulations on purchasing your Wisdom Audio subwoofer. The STS’s Regenerative Transmission Line™ technology delivers tremendous bass performance in terms of depth, dynamics, and distortion resulting in articulate bass that integrates seamlessly with high-resolution main speakers such as Wisdom Audio’s Sage Series. About this manual This manual focuses on the STS subwoofer itself.
Description Your Wisdom Audio STS 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.
Uncrating the STS The Wisdom Audio Sage STS subwoofer is a substantial piece of equipment. Please exercise caution when unpacking your STS to ensure that you do not strain yourself from its (perhaps unexpected) weight. Caution! Do not attempt to lift your STS by yourself. Unpacking this subwoofer is clearly a two person job. It is unwise for a single person to attempt doing so. Do not attempt to lift your STS while bending or twisting from the waist. Use your legs for lifting, not 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 often introduce deviations of as much as 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.
ented planar magnetic hybrid speakers that will match your Sage loudspeakers superbly; place them as close to the edge of the screen as is practical. Surround Speakers Surround channel geometry In a 5.x channel system, the surround should be placed either directly to the sides of or slightly behind the listening area (90°–110° from the center channel, as seen from above). In a 7.
have the luxury of doing so, this simple placement strategy can reduce the size of the room’s response irregularities from 20 decibels down to perhaps as little as 6-8 decibels—a tremendous improvement. Reducing the room’s inherent problems to this degree provides a huge advantage. It allows the SC-1 System Controller to put its considerable abilities to work on perfecting your system’s response, rather than on trying to perform major corrective surgery.

Setting Up the STS There is no escaping the fact that the STS is a large subwoofer. That being said, it is designed to have remarkable installation flexibility for something so large. It may be used standing upright, or laying down on its broad side, in which case it can be built into a set of risers or as part of a “stage” in front of the screen. The STS also includes three locations for the exit of the Regenerative Transmission Line™.
Making the STS Connections As with any system, you should make changes to the connections only when the power is turned off to avoid any chance of inadvertently causing a problem (such as a short-circuit). We recommend using heavy-gauge speaker wire, particularly when the installation forces you to use longer wires than you might otherwise. A good rule of thumb is to keep the “loop resistance” below 0.1 ohms. The loop resistance can be easily measured with an inexpensive volt-ohm meter.
Optimizing the System A Wisdom Audio loudspeaker system is just that: a system, designed to provide the highest calibre of performance, in the widest variety of possible settings. As such, simply connecting all the wires does not mean the system is optimized. The SC-1 System Controller manual has the pertinent details on precisely how to use it to optimize the performance of the system. For the purposes of this manual, a quick overview of the process is sufficient. 1.
