Recommended Power Amplifiers
| Nominal Impedance | Required Channels | Amp Power Rating |
| 8 Ω | 1 | 600 – 2400 Watts |
Selecting the proper amplifier size for a given loudspeaker requires analysis of the transducer’s long-term (or RMS) power rating, dynamic range of the input-source material (crest factor), desired sound pressure levels, and other factors. As a general guideline, the following table provides recommended power amplifier ranges for the ShowTime SK12 loudspeaker.
Rotating the High-frequency Waveguide
The high-frequency waveguide in the ShowTime SK12 loudspeaker can be rotated to accommodate horizontal or vertical loudspeaker mounting. The SK12 is assembled in the factory for vertical mounting. To rotate the waveguide for horizontal mounting, do the following.
- Remove the screws from around the loudspeaker grille and remove the grille from the enclosure.
- Remove the waveguide screws.
- Pull the waveguide forward, rotate it 90°, and place it back into the enclosure.
- Secure the waveguide using the screws removed in Step 2.
- Reattach the grille using the screws removed in Step 1.
Loudspeaker Orientation
SK12 loudspeakers can be mounted horizontally or vertically. Choose the loudspeaker orientation best suited for your installation. You can rotate the Bose Professional logo to align with your loudspeaker orientation by pulling gently on the logo, turning it to your desired position, and pushing the logo back into place.

Q: Is the SK12 suitable for outdoor installation?
Indeed. Generally speaking, the SK12 is weatherproof, built to withstand humidity, temperature fluctuations, and light rain. For optimal longevity, mount it under protective coverings wherever feasible.
Q: Does the SK12 support 70V/100V distributed audio?
Yes, a lot of SK12 models have an integrated transformer with movable tap positions. Depending on your amplifier output and system architecture, choose the appropriate wattage tap.
Q: How do I set the transformer tap or impedance?
To change the power levels (e.g., 10W, 20W, 40W, 60W), use a screwdriver. Set the selector to 8Ω or the designated bypass option for low-impedance mode.
Q: Can I rotate the speaker to aim the sound?
Indeed. You may guide sound towards the listening area for the best coverage by using the mounting bracket’s tilt, swivel, and rotation capabilities.
