9 due to harmony’s unique patented design, installation is identical for new or existing construction. The harmony speaker is designed to perform at its best when the bot- tom of the speaker is located well off the floor (about 2.5 feet). While it may be in- stalled at greater heights, it will perfo...

11 - using a drywall saw, cut out the wall opening for the harmony speaker. The inward facing edges of the studs will serve as vertical guides for the saw. When cut properly, an opening approximately 39.25” x 14.5” will result. (figure 3) warning: wear eye protection when cutting dry wall. Also be c...

18 before you purchase loudspeaker wire, check local building codes to make sure that the wire is rated to comply with applicable local safety codes such as ul or cl-2. Use only stranded wire no thinner than awg 16. For runs longer than 100 feet, we recommend minimum of awg 14. When pulling wire, ta...

20 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 lon...

23 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 ...
