  • Page 6: Warranty

    Warranty Legacy Audio supports its customers and products with pride. 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)years.

  • Page 7: Speaker Placement

    The amount of recommended "toe-in" is a function of the lis- tening angle. As the overall listening angle increases from 40 degrees, the amount of toe-in should increase. Your Legacy speaker is optimized for a flat response in the far field. Best results are obtained vertically with the lis- tener's ear at tweeter level with the loudspeakers gently toed in toward the listener.

  • Page 8: Hooking Up Cables

    Hooking Up Cables The ideal conductor would have negligible resistance, inductance and capacitance. The table below shows how a few actual speaker cables measure up. Cable s/ft pF/ft µH/ft 12 ga. 0.0033 0.21 14 ga. 0.0048 0.13 16 ga. 0.0079 0.18 18 ga.
  • Page 9 Hooking Up Cables 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 longer than this just to transmit phase information, phase shifting is obviously not the primary concern when considering speaker cables.
  • Page 10 For this reason, extensive measures have been taken to ensure that each Legacy speaker system represents a smooth, non-reactive load to virtually any amplifier. Often there is much confusion regarding amplification and loudness levels. It should be under- stood that the role of the amplifier goes beyond that of driving loudspeakers to a given sound pressure level.
  • Page 11 Some audiophiles feel that 200 watts per channel is the bare minimum to avoid audible clipping distortion when reproducing music at “live” playback levels. Your Legacy speakers are designed to take advan- tage of “high-powered” amplifiers, so don’t be afraid to put them through their paces.
  • Page 12 Amplification 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 loud as a 15 Watt amplifier.

  • Page 26: Continuing The Pursuit Of Perfection 2 5 -2

    Continuing the Pursuit of Perfection (Legacy Air Motion Ribbons) LEGACY Audio has been benefiting from low mass ribbon and leaf drivers since 1984. I have a col- lection of ribbon tweeters from the world over and always loved the way good ribbons reproduced the swishing sound of brushes on a snare- and the simple honesty in the reproduction of strings without imparting an edgy ringing effect found in most tweeters.
  • Page 27 (Legacy Air Motion Ribbons) The recent Aeris loudspeaker development gave me the opportunity to tool a new AMT folded ribbon tweeter to integrate with the smoothest high efficiency 8” midrange built to date. I have yet to find a driver to challenge it. This silky 8” mid has a range of 7 octaves with nary a wrinkle in the response, yet a sensitivity of 98 dB.

  • Page 34 Wavelet Speaker Connections for Aeris Let's first connect the outputs of your Wavelet to your Aeris speaker and external amplifier. These outputs are all that are necessary to setup your Wavelet with Aeris. The input connections from your Player, Transport, Preamp etc. can be connected after setting up your Wavelet.
  • Page 35 Optimizing Analog Outputs When using the analog inputs it is useful to optimize the input levels according to how they are being used. This will maximize the signal to noise ratio and provide optimal gain while preventing distortion from input overload.
  • Page 36 with the -12dB setting initially as shown below. Further attenuation of -3, -6dB is available if needed. While you can also further reduce the volume setting from your preamp, the goal is totally avoid clipping at all levels. Again try to establish a Wavelet level setting of about 85dB for typical listening. With a little care you will have minimized your noise floor and prevented input saturation.

  • Page 54 Maintaining directivity in the speaker radiation pattern is essential to preserve this content. Legacy V, Whisper, and Aeris each offer unique directivity control to provide greater clarity, better localization and resonance reduction.
  • Page 55 Why is Room Correction Necessary? To the left is a 2 dimensional simulation of a 1ms wave pulse from a pair of conventional speakers into a room similar to the above. Because the dispersion exceeds 60 degrees, undesirable energy from each speaker is reflected back into the room within a few thousandths of a second.
  • Page 56 After less than 1/100 of a second, the room has developed a complex wave pattern with energy varying with room position. The listener is now awash in a series of wave-fronts which will soon reflect off the wall behind. A mere 5 milliseconds later, the initial direct wave-front has now reflected off the rear wall and has made its way back to the listener.
  • Page 57 To the right is the irregular frequency response of a speaker on axis in the presence of room boundaries. The smoothed curve is the result of applying conventional room correction methods. Below left is the impact of the correction on the Fequency-Time domain.
