Polyester fiberfill is selected for internal damping. A sharp rap on the enclosure will leave you with little more than bruised knuckles. Ea...

We cheerfully warrant our loud- speaker products we manufacture from defects in materials and workmanship for a period of seven (7) years. Electronic components such as internal amplifiers and digital processors are covered for three (3)...

6 your new speaker system has been very carefully packaged to insure that it travels to you safely. Each speaker is protected by a double- wall outer carton with heavy v-board corner protectors. Molded foam end caps are used to protect the elegant cabinetry, and a plastic liner is provided as waterp...

7 to allow more flexibility in seating arrangements, your legacy loudspeaker is designed for broad lateral coverage. Optimal listener position is actually about 5 to 15 degrees off the axis normal to the loudspeaker baffle. Assum- ing a listener distance of about ten feet, begin by placing the speak...

9 what about phase shift due to frequency dependent travel times down the speaker cable? Measurements show that 100 hz waves will be delayed about 20 billionths of a second behind 10 khz waves when traveling to the end of a 10 foot speaker cable. Since the cilia of the ear requires 25,000 times long...

10 ideally the loudspeaker would be among the first components selected when assembling a play- back system. This would allow the user to choose an amplifier capable of delivering adequate amounts of current into the frequency dependent load presented by the loudspeaker. However, when upgrading a sy...

11 how much power will your new speakers need? That ultimately depends on your listening environment and musical tastes. As little as five watts per channel should drive them to a level satisfactory for background music. A typical 45 watt per channel receiver may fill a room with the compressed mid-...

12 when an amplifier is unable to fulfill your loudspeakers demands, a damaging harmonic spike may be leaked to the high frequency drivers. Another important point regarding loudness is that the db scale is a logarithmic one. This means that a 150 watt amplifier will potentially sound only twice as ...

13 step 1- carefully place your speakers on their sides step 2 - locate the cone feet set. It will be inside the foam pieces that held the speaker in the box. Foot installation.

14 step 3- place the insert adapter into the rubber cone. Step 4 - thread the cone insert into the cabinet. Foot installation.
Page 15
15 step 5- tighten the cone insert. If you do not want the spikes, you may stop here. Step 6 - place the leveling washer onto the cone. Foot installation.

16 step 7- install the washer and cone onto the speaker. Adjust the cone until your speaker is level. Foot installation.

17 the terminal plate at the rear of each of your loudspeakers you will find a terminal plate housing two rows of jumpered binding posts. The upper row is the input to the "satellite" portion of the speaker. The lower row is the input to the "subwoofer" portion of the speaker. When left in place, th...

18 biwiring biwiring allows one to minimize the cable losses between the amplifier and the loud- speaker. This is accomplished with a single stereo amplifier by running separate sets of cables to the satellite section and the subwoofer section from the same channel of amplification. When biwiring, w...

19 1. Vertical biamping vertical biamplification requires the dedication of a single stereo amplifier for the left speaker, and another stereo amplifier for the right speaker. This configuration im- proves channel separation and can improve imaging slightly. If your preamp does not have two sets of ...

It does not apply towards the separate powered subwoofer/satellite configuration. You must always observe the polarity when connec...

21 also helpful is bass equalization and subsonic filtering. When cascading active filters with the existing passive filters within the speaker system, be sure to allow for ade- quate frequency overlap. For instance, if the passive crossover is set at 500 hz, select a low pass corner frequency of 60...

22 to facilitate proper set-up of your speakers in a variety of room situations, we have included several heavy duty toggle switches on the terminal plate, located on the back of the loudspeaker. All switches in the “up” position represent the “anechoic flat” position. Treble trim: - nominally flat ...
