Summary of Contents for Legacy V System

  • Page 1 Owner’s Operating Manual...
  • Page 2 Thank you for purchasing the Legacy V loudspeaker system! The Legacy V is a full range loudspeaker system utilizing the present state of the art in driver, crossover, amplifier and acoustic radiation control technologies. The Legacy speaker system is designed, assembled and tested in Springfield, Illinois by a dedicated group of engineers, craftsmen and music lovers.

  • Page 3: Owner's Record

    Owners Record Thank you for selecting a Legacy Loudspeaker System. These handcrafted instruments will provide you with many years of listening enjoyment. The serial number is located on the rear of each unit. You can record this number in the space provided below. Refer to this when calling your dealer regarding this product:...
  • Page 4 Uncrating Each V speaker has been carefully packaged in a specially designed crate to ensure they reach you safely and undamaged. You will find the Top, Front and Back panels labeled on each crate as well as the Left/Right speaker designation. Screws that are to be removed will be painted black for your reference.
  • Page 6 Inside the Wavelet processor carton packaging you’ll find a hard-case containing a measurement microphone, a 25 ft. XLR cable and a mic calibration plot. At the opposite end of the carton you will find a power supply with a five pin locking connector and its 115 V AC cable, a compact remote volume control, a Wi-Pi network connector and a SanDisk USB memory stick.

  • Page 8 Wavelet At the heart of your V loudspeaker system is the Wavelet processor. Wavelet is a control preamp, a premium DAC, a digital crossover with time alignment for each driver section and an acoustic correction system that will literally ‘learn’ your room. True digital flexibility SPDIF, TosLink: up to 96kHz/24bit USB: All file formats up to 96kHz/24bit are sent directly from the PC to the Wavelet without any conversion.
  • Page 9 In the J-River software this configuration is located in the Player -> DSP Studio - Output Format section. Setup all sample rates up to and including 96ks to “No Change”. Then set input 176400 to output 88000, 192000 to 96000 and greater than 192000 to 96000. DSD is converted automatically in the software to PCM.

  • Page 12: Speaker Connections

    Speaker Connections The standard V system provides two channels of amplification internally for the subwoofer and bass drivers. You will need to supply two additional channels for the lower midrange (60 watts minimum) and midrange/treble (30 watts minimum) of each speaker. Additional channels of internal amplification can be provided by special order.

  • Page 14 Your Wavelet processor has a serial number located on the decal adhering to the top of the unit. There is also a permanent sticker on the rear corner of the unit which indicates this number. The Wavelet can connect to the network via WiFi or Ethernet. Wavelet features can be remote controlled via iPad, iphone, or other mobile device.

You will enter your network name and password between the quotes as shown, and then save over the wifi- conf.txt file that exists on the removable SanDisk memory stick. When you insert the stick into the Wavelet USB port with the power off (standby), the unit will load into memory the new network name and...

  • Page 23 Loudspeakers continue to be the weakest link in the playback system by an order of magnitude and more. It’s easy to understand why. Driver elements must combat startup inertia. Once in motion they fight inertia again to stop, continuing to oscillate post signal. It’s well known that distortion is proportional to diaphragm travel requirements.
  • Page 24 Controlling the Directivity of Sound While Legacy Audio has continued to improve directivity in loudspeaker designs for more than 2 decades, speakers with deviant radiation patterns continue to exist in the marketplace. While their high frequency drivers tend to be cardioid in pattern, lower frequencies progressively become omni- directional.
  • Page 25 Ideally, speaker systems would fully cover the listening area while avoiding early reflections. This is desirable at all frequencies to avoid masking the key temporal cues of the recording venue. Even the best loudspeakers do not radiate uniformly with frequency. This lack of directivity control greatly skews the room power balance, reduces clarity and drives room resonant modes heavily.
  • Page 26 The shadowing to the far ear from the source is quite fragile in a reflective environment. 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...
  • Page 27 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 28 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 29 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.
  • Page 30 The Engineer’s Perspective thoughts from Legacy Chief Designer, Bill Dudleston  The listening room greatly diminishes left/right separation as frequency decreases, reducing or destroying spatial cues at each ear.  Reflections superimpose an additional room environment onto the listening experience, masking the original recording venue which we strongly desire to preserve.
  • Page 31 subjective attractiveness of sound. By manipulating the spatial properties as a function of frequency the recording engineer has a chance to control factors in the sound which influence spaciousness, depth, richness, envelopment without affecting factors which influence placement. It is the lateral sound energy which creates pressure differences between the two ears of a front-facing listener at frequencies below 700Hz.
  • Page 32 While the amplifier is very important, the loudspeaker is traditionally the limitation in the playback chain. To address this, the V system with Wavelet processor corrects each driver section individually, compensates and aligns them in the time domain, then examines the summation acoustically and fits it to the target curve. Lastly it samples the radiation into the room and provides the final correction, removing time domain errors and resonances as old as 40ms.
  • Page 33  The Wavelet processor virtually eliminates digital pre-ringing of brick wall filters via apodization. We will also be offering the Wavelet processor in time for some of the other Legacy speakers. But before we move on to our next conquest, let’s kick back a bit and savor the results of this one …...
