Subwoofer installation

Mounting options

Your subwoofer has three mounting possibilities. (You will need an assistant to help lift and position the subwoofer.)

A. Free standing.

Two brackets are easily fitted to the subwoofer with thumbscrews.

B. Vertically.

The subwoofer can be fitted up against a wall, with one foot bracket on the floor. The subwoofer must be held to the wall using special fittings sup- plied, and it must have one of the foot brackets fitted to the lower edge.

Never leave the subwoofer standing vertically without it being secured to the wall.

C. Flat.

The subwoofer can be fitted with four supplied feet, and placed on its back. It can even fit under couches.

See page 18 for more details of the different mounting options.

Finding a good location

Although low frequencies are non-di- rectional, factors such as room reflec- tions, standing waves, resonance and ab- sorption will strongly affect your subwoof- er’s performance. Moving the subwoofer from one location to another can have a major effect on the bass response.

The Auto EQ mode will let you adjust for the room effects, but you should find the best location first.

The following procedure will help you find the best location for your subwoofer. (This method may seem a bit odd, but it is based on solid principles of acoustic physics.)

1.Start by placing the subwoofer right on the seat of your favorite couch or easy chair, with the woofers fac- ing upwards. Position it with care so it is not likely to fall off. If this is not practical, then move the couch and place the subwoofer either face up with four feet attached (mount- ing option C), or horizontally with two brackets attached (option A).

2.Connect the SubRosa amplifier and the subwoofer with speaker wire, and connect a power cord to the amplifier.

2.If you are using the subwoofer as part of a Home Theater system, you can either run a calibration test (noise) signal through the subwoofer, or simply plug the ana- log outputs of a CD player directly into the sub amp’s line-level inputs. Turn down the sub amp's volume level before turning on the CD, then play some of your favorite music samples with heavy bass.

3.Walk around the room, listening, and stand in all the positions where you might be able to place the subwoofer. Try crouching down, and try the corners. Find the most practical place where the subwoof- er's bass output sounds best.

4.Shut things down and install the subwoofer in this position.

Magnetic Fields

We recommend that you place your subwoofer further than two

feet away from your TV, VCR, tape deck or computer, so the speaker’s magnet won’t distort the colors of your TV

picture or erase your video tapes, audio tapes or computer discs.
