Placement

The X-tra "Tweek"

A major cable company developed the following proce- dure for speaker placement. As a final test of exact placement, use these measurements for your speakers placement, and see what can happen to the ultimate enhancement of your system's performance.

The procedure consists of two basic measurements:

1)distance from the front wall (wall in front of the listening position) to the center of the curvilinear transducer.

To determine distance from the front wall, measure the height of your ceiling (inches) and multiply the figure by

.618 (i.e. ceiling height in inches X .618 = distance from the front wall to the center of the curvilinear transducer).

2)distance from the side-walls to the center of the curvilinear transducer.

To determine distance from the side-walls, measure the width of your room (inches) and divide the figure by 18, next multiply the quotient by 5 (i.e. (room width in inches/

18)X 5 = distance from the side-walls to the center of the curvilinear transducer).

These two formulas will determine optimum placement of your speakers to minimize standing waves.

Solid Footing

After living and experimenting with your Quests, you will then want to use the spikes included in your owners kit. The Quest will become more firmly planted on the floor and, consequently, bass will tighten and imaging will become more coherent and detailed. It is best not to implement the spikes, however, until you are secure in the positioning as the spikes can damage the floors if the speaker is moved.

Enjoy Yourself

The Quest is a very refined speaker and, as such, benefits from care in set-up. With these tips in mind, you will find, over your months of listening, that small changes can result in demonstrable differences. As you live with your speakers, do not be afraid to experiment with their positioning until you find the optimal relationship between your room and your speaker system to give you the best results. Your efforts will be rewarded.

You are now armed with the fundamentals of room acoustics and the specific fundamentals of the Quest loudspeaker. Happy listening!
