4 handcrafted beneath the surface of whisper hd’s elegant exterior lies rigid mdf construction. Interlocking joinery maximizes the strength of the cabinet parts. Polyester fiberfill is selected for internal damping. A sharp rap on the enclosure will leave you with little more than bruised knuckles. ...

5 positioning whisper for good performance is quite a bit easier than for most speakers. Remember that whisper is actually an acoustic gun with a highly controlled directivity pattern. Corner place- ments are actually quite workable though not necessarily optimal. Whisper will not become “boomy” lik...

7 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...

8 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 sys...

9 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-b...

10 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 ...

11 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...

12 biwiring biwiring allows one to minimize the cable losses between the amplifier and the loudspeaker. 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, we ...

13 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 con- figuration improves channel separation and can improve imaging slightly. 2. Horizontal biamping any two stereo amp...

Fac- tory settings are ‘plug and play’, and do not require a computer to utilize. Connections between the preamp and power amplifier should be as below. Fun...
