frequencies go where you point them. Simply aim the center axis of the speaker into the plane slightly above the listening area. The 90" x 90" horns of the Control@Contractor Series disperse the high notes by 45" off axis in every direction. For large or unusually shaped rooms, divide the area into zones and let the horn patterns dictate the spacing between the speakers (see diag. 5) -

TYPICAL DAISY CHAIN CONFIGURATION

TYPICAL "HOME RUN" CONFIGURATION

Boundary Loading - This is a good trick for increasingbass without taxing the amplifier. It is also possible to make a system sound too "muddy",so use caution. If you move the speaker from open space to a wall, bass notes will increase by + 3dB. If you move it to a 2 boundarycorner, another t3dB...and another t3dB for a three boundary corner! (see diag. 4).

Daisy Chaining - It is most common, easiest, and cheapest to run wires from the amp to a speaker, then from that speaker to another (see diag. 6A).

Home Runs - If you desire true stereo L & R from each listening position, "home runs" are best, from the amplifier directly to each speaker (see diag. 6B).
