The Extra “Tweak”

This may be useful when your speakers are placed in a dedicated listening room. Use the following procedure for your speaker’s placement to see what can happen to your system’s performance. These formulas will help determine optimum placement of your speakers to minimize stand- ing waves.

1Distance from the front wall (in front of the listening position) to the center of the curvilinear transducer: To determine distance from the front wall, measure the ceiling height and multiply the figure by 0.618 (i.e. ceil- ing height x 0.618 = the distance from the front wall to the center of the curvilinear transducer).

Example: 9 feet x 0.618 = 5.5 feet

2Distance from the side-walls to the center of the curvi- linear transducer: To determine distance from the side walls, measure the width of your room and divide by 18. Next, multiply the quotient by 5 (i.e. room width in inches / 18 x 5 = the distance from the side-walls to the center of the curvilinear transducer).

Example: 14.5 feet / 18 x 5 = 4 feet

Solid Footing

After living and experimenting with your CLX’s, you may want to use ETC (energy transfer coupler) spikes supplied with the CLX (figure 5) to adjust rake (figure 6) and to cou- ple the CLX to your floor. With the use of these spikes, the CLX 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 position- ing, as the spikes can damage the floor if the speaker is moved. The feet that attach to the bottom of the CLX use a common 3/8 - 16 thread.

Spike .Installation .Instructions:

1Carefully lay your speaker on its side.

2Remove existing feet or spikes. Thread new spikes into holes and screw them in all of the way.

3Tighten the jam nut snugly by hand. Do not over tighten.

4Stand the speaker up. Caution: .Make sure hands and any cabling are clear of the spikes. Do not slide speaker as sharp spikes can damage your floor or carpet.

5Adjust level by loosening the jam nut then rotating the spike. Tighten the jam nut securely when satisfied with the speaker’s rake.

Enjoy Yourself

The CLX is a very refined speaker and benefits from care in setup. You will find, through extended listening, that small changes may result in audible differences. As you live with your speakers, do not be afraid to experiment with their positioning to find the optimal relationship between your room and speaker system. Your efforts will be rewarded.
