S57i Dimensions | 20 DOCUMENT CONVENTIONS This document contains general safety, installation, and operation instructions for the Wisdom Audio High Output TL Subwoofer. It is important to read this document before attempting to use this product. Pay particular attention to: WARNING: Calls attention to a procedure, practice, condition or the like that, if not correctly performed or adhered to, could result in injury or death. -
Page 3: Introduction
Factory Personnel. NOTE: For optimal performance, you MUST use an SW-1, or SA-DSP amplifier. The S57i (like all TL subwoofers) requires a very specific non-standard EQ slope to ensure proper performance. -
Page 4: Subwoofer Placement (An Introduction)
Subwoofer Placement (An Introduction) Subwoofers offer flexibility in placement since the frequencies they reproduce are not readily localizable by the human ear. This is because the wavelengths they reproduce are more than 10 feet (3 meters) long, but our ears are located only about 6-7 inches (17 cm) apart. -
Page 5: Room Treatment
Note: Room treatment for Satellite Speakers is quite different and can be very effective in changing the sound character of the room and improving detail, intelligibility, and imaging. More information on this can be found in other Wisdom publications not dedicated to subwoofer installation. - Page 6 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.

Page 7: Unpacking The S57I
*The scrim cloth is provided for optional aesthetic use. Installing the S57i The following provides an overview of the S57i installation in a standard stud wall, a very straightforward process. It is expected that the installer has common knowledge and a basic understanding of construction principles sufficient for the task. - Page 8 The front board of the S57i is made from 1/2" MDO plywood, which has a smooth, paintable surface finish like drywall. It can be taped, textured, and painted like any other wall surface. It will also accept skim-coating if construction calls for plaster walls.
- Page 9 Alternatively, if you have access to the adjacent stud bay, drill a hole through the 2x4 stud adjacent to the S57i’s feet, and feed the cable through the hole. (This method is shown in subsequent installation images in this manual.) You can then make the connection within the subwoofer bay or in the adjacent stud bay.

Page 10: S57I Attachment
Press Short-length Shims into Place as Shown. S57i Attachment Set Height Using Temporary Support Screws. 5) Set mounting height of the S57i. Determine the desired height of the S57i and install a temporary support screw into each stud to support the bottom of the enclosure. - Page 11 6) Screw the S57i to the studs. NOTE: The S57i should be attached in a manner that does not subject it to bending or torsional (twisting) forces that would stress the enclosure. No wooden or metal enclosure should be forced against an irregular surface. If the studs are curved or warped in an installation, the installer must insert shims between the S57i front panel and the stud surfaces to avoid such stress.

Lift the lever of the empty terminal to open the clamping mechanism and insert a stripped conductor. - Page 13 9) Secure wires, by wrapping and attaching as needed to prevent unwanted vibration. a) The cables and connections can be wrapped with soft material that prevents them from directly touching adjacent hard surfaces. If access permits, the cables can be secured using appropriate hardware such as cable ties, Velcro®, staples, etc.

Page 14: Finishing
Finishing 12) Paint and Finish Surface: a) The face of the S57i has a surface finish similar to drywall. It can be taped, mudded, and painted like any other section of wall. It will also readily accept skim-coating if the construction calls for plaster walls. - Page 15 14) Install the grille to the front of the S57i. a) Place the grille alongside the magnets, and adjust the height of the magnets using a #2 Phillips screwdriver. The magnets should be adjusted so they are approximately 1 to 1.5mm below the outer face of the grille.

Page 16: Attaching Scrim To Grille (Optional)
Attaching Scrim to Grille (Optional) If you choose to use the included scrim behind the grille, the material should be attached using 3M 77 spray adhesive. The scrim will make the grille more opaque and slightly more difficult to see through the grille. However, it will also impede the movement of air through the grille at high sound levels and the lowest frequencies. -
