Page 5 of 30 Unpacking Your Speakers Your new speaker system has been very carefully packaged to insure that it travels to you safely. Each speaker is protected by a doublewall outer carton with heavy V-board corner protectors. Custom fitted foam end caps are used to protect the elegant cabinetry, and a custom bag is included to provide further protection. Please save this packing for future transportation. If cartons become damaged or misplaced, new ones can be purchased from Legacy Audio. Page 6 of 30 Speaker Placement 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. Assuming a listener distance of about ten feet, begin by placing the speakers approximately 7 feet apart and about 1 3 feet from the wall behind them. In most rooms this will afford a speaker position at least 2 feet or more from the side walls. The amount of recommended "toe-in" is a function of the listening 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 listener's ear at tweeter level with the loudspeakers gently toed in toward the listener. Increasing the degree of toe-in is recommended when placement next to sidewalls is required. Placing the loudspeaker or the listener near a room boundary will generally increase low frequency impact. If you are forced to position one or both of your loudspeakers in a corner, be prepared to reduce bass output via the control switches on the rear terminal plate of each loudspeaker. You may also wish to reduce low frequency output with your preamp's bass tone control. Page 7 of 30 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 12 ga. 14 ga. 16 ga. 18 ga. s/ft 0.0033 0.0048 0.0079 0.0128 pF/ft 24 17 16 28 µH/ft 0.21 0.13 0.18 0.21 Capacitance is considered insignificant in each cable because its effect is well out of the audio bandwidth; inductance can be decreased (at the expense of increased capacitance) by keeping the conductor pair closely spaced. How long would a cable have to be before inductance effects would impinge on the audio spectrum? Approximately 300 feet of 12 gauge would be required to establish a corner frequency of 20 kHz with an 8 Ohm loudspeaker. As you see, inductance is not a problem for most of us. Page 8 of 30 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. What about resistance? Finally we are getting somewhere. Resistance is the controlling factor of the amplifier/loudspeaker interface. Excessive resistance can cause major shifts of speaker crossover frequencies. The lower the impedance of the loudspeaker, the greater the effects of series resistance. A 20 foot run of 18 gauge cable can cause up to 10% deviations of crossover center frequencies. That same 20 feet can un-damp your damping factor and reduce your systems' output by one half decibel. In summary, there are no perfect cables. The best way to approximate the ideal would be to keep loudspeaker leads as short as is practical. Page 9 of 30 Amplification 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 system, audiophiles may find themselves matching their new loudspeakers to their existing amplification. 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 understood that the role of the amplifier goes beyond that of driving loudspeakers to a given sound pressure level. The amplifier should be able to CONTROL the loudspeakers across the entire music spectrum. This means that parameters such as damping factor (values greater than 60 are acceptable) and dynamic headroom should not be overlooked when comparing amplifiers. Page 10 of 30 Amplification 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-band energy of "heavy metal," but seem to lack weight or control with classical recordings. 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 advantage of "high-powered" amplifiers, so don't be afraid to put them through their paces. How much is too much power? Rarely is a drive unit damaged by large doses of music power. More often than not the villain is amplifier clipping distortion. Even through decades of refinement, loudspeakers are still notoriously inefficient transducers, requiring huge amounts of power to recreate the impact of the live performance. Typically less than 1% of electrical power is converted into acoustic output. (For example, an omnidirectional transducer with an anechoic sensitivity of 90 dB @ 1w/1m has a full space efficiency of only 0.63%) Page 11 of 30 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. If all of this discussion of power and loudness seems a bit abstract, consider the example below. The average acoustical power developed by a person speaking in a conversational tone corresponds to a mere 0.00001 Watts. The power that would be developed by the entire population of the city of New York speaking at once would barely illuminate a single 100 Watt light bulb. Page 12 of 30 Installed Feet Your speakers come with threaded adapters and rubber cone feet installed. Should you wish to purchase after-market products, the thread size specification for your vendor is M12, 1.25mm. Page 13 of 30 Focus XD Enhances Versatility Adding 750 Watts of Internal Power The renowned Legacy FOCUS is now available in both the award winning SE version and the powered XD version. Be careful to understand the FOCUS XD is not a replacement for the FOCUS SE, but a more versatile internally amplified version of the same, facilitating both passive and active bi-amplification. The fully passive FOCUS SE will continue to hold its position in the Legacy line-up. The new Focus XD version includes a high quality internal 750 watt amplifier which provides some unique performance options: · Use this internal ICEpower amp with its 30 amp peak current capability to drive the entire speaker full range via the passive internal crossover. Merely a source and a preamplifier are required to drive FOCUS XD to breathtaking levels. This is a common configuration for studios and those with DAC/Preamps. · Allocate the internal amp's 750 watts entirely to the bass section to power the lower 12" woofers of Focus XD, while driving the upper section with your external amplifier. This method of passive bi-amplification minimizes current demands from the upper range amplifier and reduces the presence of back EMF from the woofers. Your amplifier will work less hard and the speaker will sound more effortless. · Utilize an external crossover such as the Legacy Wavelet II or Wavelaunch processors. Link the woofers directly to the internal amp, eliminating the passive crossover from the path. This improves coupling with the woofers and increases drive efficiency by nearly 30%. Both the Wavelet II and Wavelaunch processors are presently available with customized settings for the FOCUS XD. Page 14 of 30 Background Over 30 years of continuous refinement has brought the Legacy FOCUS to its present level of precision and performance. Audiophiles, studio professionals and home theater integrators recognize the FOCUS as the go-to reference of full range speakers. It earned this reputation by going deeper and cleaner with greater dynamics than speakers at more than twice the cost. The Focus XD incorporates the same dual 12" ultra-linear bass drivers and Legacy Dual AMT system as the Focus SE while employing new dual 7" graphene filled carbon fiber midranges which feature a massive magnetic structure, computer optimized copper phase-plug and shorting ring. The dual 12" woofers of the Focus XD deliver unprecedented linear output with snap and definition with rich upper bass and clean transition to the lower midrange owing to a 15 lb motor structure. Each inductor is hand wound to a precise value. Silver HF wire and high quality Solen capacitors are utilized. The crossover is designed and fine-tuned by our Chief Engineer, Bill Dudleston. Each pair is carefully matched under his personal supervision. With the addition of the 750 watts of internal power, users can take full advantage of bi-amplification benefits: lower harmonic distortion, reduced back EMF (better damping), greater dynamic range and reduced intermodulation.

You may upgrade to XD level performance a number of ways: · Passively bi-amp by adding a Legacy iV2 or Powerbloc2 with 750 watts of power to the bass section of each FOCUS SE, while driving the upper section with your external amplifier. This method of passive bi-amplification minimizes current requirements from the upper range amplifier and reduces the presence of back EMF from the woofers. Your amplifier will work less hard and the speaker will sound more effortless. · Or power both top and bottom with the four channel Legacy iV4 or Powerbloc4. This assures perfect level matching to the upper and lower range. · Actively bi-amp adding Legacy's Wavelet or Wavelaunch processors and a Powerbloc2 amplifier. This improves coupling with the woofers and increases drive efficiency by nearly 30%. Both the Wavelet and Wavelaunch processors are provided with customized settings for the Focus XD. This requires a simple factory authorized modification. Contact the factory for details. Page 23 of 30 Additional Q&A Can I use the Wavelet or Wavelaunch processors with the Focus SE? Absolutely. Either processor can be factory configured for your Focus SE system. What is the performance difference between the two processors? The Wavelaunch can be used as a crossover and adds user adjustable room equalization. We recommend using the free Mobile Tools app https://appsto.re/us/ssP74.i to calibrate your system. Besides being a premium preamp/DAC with apodizing to remove digital pre-ringing, the Wavelet offers driver correction algorithms to improve transients in the time domain, automatic room correction, amplifier level matching, tonal contouring and more. Assuming I use the Wavelet, what is the difference I can expect between Focus XD and Aeris? Aeris has greater directivity control and longer throw for larger rooms. Though it works equally well in small rooms, the resolution is greater with the Aeris in the top end. If I have Focus SE already, can I use an iV4 or Powerbloc4 amplifier with a processor? That is actually the motivation for our four channel amplifiers. The other option is a pair of iV2 or Powerbloc2 which can provide double the current for perfectionists. I presently own a pair of subwoofers. How can I use them with Focus XD? A processor is recommended to take greatest advantage of the added piston area without clouding the bass. You would be using outputs 3, 7 on either processor. The Wavelet will automatically optimize the overall bass summation. The Wavelaunch can be optimized manually with an analyzer such as Mobile tools. Page 24 of 30 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 collection 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. There's just something right about the sound like a C12 mic capsule. If one could increase the dynamics to natural levels and extend the range of ribbons without beaming undesirably, the benefit would be considerable musically. I have always been a proponent of low mass, high acceleration drive elements. The acceleration capability of the drivers ultimately determines the transient or waveform tracing capability of the loudspeaker. To build a better speaker, one MUST first acknowledge that loudspeakers are dreadfully slow by nature. Their responsiveness lags the electrical waveforms settling time by orders of magnitude (Logically so, if one contrasts the mass of an electron to the mass of a speaker diaphragm.). Typical of transducers (devices that convert one form of energy to another), speakers are also extremely inefficient -wasting more than 98% of their input power in the form of heat and out of phase motion. For these two reasons I have been working with speaker driver motors with magnetic field strengths as high as 2 Tesla (60,000 times the field strength of our planet Earth) to overcome these limitations. With such field strength, greater levels of articulation are possible at the lower limits of a transducer. For example, the reproduction of a simple strike of a heavy anvil will reveal tones that are richer, darker and more complex than otherwise possible. In 2006 Legacy Audio introduced our first air motion transducer; a modernized version of the AMT tweeter developed by Oskar Heil in the 1970s. Legacy's first version utilizes a folded Kapton (not mylar) diaphragm and R45 neodymium wafers instead of ceramic magnets. The result was higher efficiency and greater power handling. This translated to significant gains in dynamic range and reduced distortion. We soon adapted an existing 4" planar ribbon (the one with the round faceplate) to work in conjunction with this tweeter to facilitate the voicing of the hand-off to our 7" driver. Page 26 of 30 Continuing the Pursuit of Perfection (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. My initiative of providing a 4" AMT that could compliment these capabilities was met with the challenge of accordion-folding sixteen square inches of Kapton into the 4" long, 1" wide chamber. Neodymium again was employed to provide the flux density required. But the solution was made even more elegant by mounting the new 4" ribbon on the same faceplate as its complementary 1" AMT ribbon super-tweeter. The results were more uniform dispersion and tremendous attack. Treble now had weight instead of tizz. A natural fullness in the treble is exhibited that reminds us why we love high-end audio so much. The effortless way it forcefully squeezes out acoustic energy is readily verified by placing ones hand over the driver faceplate and feeling the suction against your palm (nope, you won't hurt it). These new drivers may be refined, but are equally rugged. I am fortunate to have chosen loudspeaker development as my life's work. It has utilized my chemical engineering, physics and mathematics background almost daily. It has offered moments of both humility and glory, but most gratifying is the reward of continual, stairstepped successes even after 30 years. I sense that this is a never ending staircase to be followed for generations as we asymptotically approach unattainable perfection.
