Owners Record The serial number is located on the rear of the unit. Record this number in the space provided below. Refer to this when calling your dealer regarding this product. Model: Goliath XD Serial No: _________________________ Date of purchase: ___________________ Thank you for selecting a Legacy Loudspeaker System. These handcrafted instruments will provide you with many years of listening enjoyment.
The Cabinetry / Our Commitment Handcrafted Beneath the surface of Goliath XD’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. Each cabinet is impeccably finished on all exposed surfaces with select veneers.
Warranty Legacy Audio supports its customers and products with pride. We cheerfully warrant our loudspeaker 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. Please register your product with Legacy Audio. Should you require service Legacy will require a proof of purchase in order to honor the warranty - so please keep your receipt.
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. Molded foam end caps are used to protect the elegant cabinetry, and a plastic liner is provided as waterproofing. Please save this packing for future transportation. If cartons become damaged or misplaced, new ones can be purchased from Legacy Audio.
Speaker Placement Since the human ear is rather poor at localizing radiation frequencies below 125 Hz, good results may be obtained in a variety of room placements. Low frequency reinforcement occurs whenever woofers are placed near room boundaries. The distance from the walls, floor and ceiling correspond to the wavelengths of the frequencies, which will reflect in phase and thus reinforce bass output.
Speaker Placement Now, while such reinforcement might actually be beneficial at very low frequencies, a way to minimize excitation of these resonances is to place your subwoofer asymmetrically relative to room boundaries. For instance, if the subwoofer is 2 ft from one corner wall, then place it 1.5 ft to 3 ft from the other. Placing the subwoofer in a corner will reduce the radiation angle and thus increase efficiency. It will also excite the maximum number of room modes and decrease distortion.
Speaker Connections Once you’ve found a place in your room, the next step is connecting the Goliath XD to your existing system. Option 1: Connecting one or two Goliath XD using LFE output If you are utilizing Goliath XD as the dedicated LFE channel for a surround system, connect the LFE output from your surround processor to the XLR input 3 of your Xilica processor. Connect an XLR cable from the Xilica processor output 1 to the XLR input on the rear of the Goliath XD subwoofer.
Speaker Connections Option 2: Connecting one or two Goliath XD for use with Legacy Helix, Whisper, or Aeris If using the Goliath XD to augment the bass performance of a Legacy Audio speaker system begin by connecting the left preamplifier output to XLR input 1 on the Xilica processor (and input 3 if using a splitter). Next connect the right preamplifier output to XLR input 2 on the Xilica processor (and input 4 if using a splitter).
Speaker Connections Powering Up Goliath XD 1. Power Cable: The supplied power cable will plug into the socket on the back terminal plate of the unit. NOTE: Try to plug into the same AC circuit as the rest of your audio system, as this will avoid hum from ground loops. 2. Power Up: In the rear of the subwoofer is the power switch. Push the switch upward to turn the unit on. NOTE : Power up the Xilica processor before the Goliath XD subwoofer to avoid sending unnecessary transients through the subwoofer.
Wave Launch Processor The high definition Digital Wavelaunch Processor hosts a LEGACY custom algorithm which automatically loads when the processor is powered on. Factory settings are ‘plug and play’, and do not require a computer to utilize. Connections between the preamp, power amplifier, and speakers should be as shown on previous pages. Selecting the Program 1. Press the MENU left arrow 2. Scroll through the programs using the job wheel 3. Press enter to select the program of choice 4.

Wave Launch Processor The XP processor will allow you to make adjustments to your system from a laptop computer from your listener position. ConnectingYourComputerwiththeXP-4080Processor - Connecting will require a long USB Device cable. These can be found at most electronic or big box stores. It is the same cable that a USB printer would use. This 16 ft cable is available at Radio Shack. http://www.radioshack.com/product/index.jsp?productId=3584358&filterName=Length&filterValue=16-20+ft.
Wave Launch Processor - Go back to the XConsole software. At the top of the screen click “Setup” then “Port Connections” This bring up a new dialog box. Select the COM port number you obtained from the device manger and click “OK.” The software will warn you that you must restart the software for your changes to take effect. - Restart the XConsole software. This time, when it asked “Do you want to connect to the device?”, answer “Yes”. - You should now be connected to the device and ready to use.
Wave Launch Processor Making Adjustments with Wavelaunch Processor After installing the included software, connect the processor to the computer via a USB cable. Launch the XConsole software. When asked if you want to connect to the device, click yes. In the Device List, click on the device that is connected. This will launch the program that is currently on the processor.
Wave Launch Processor In the Device List, click on the device that is connected. This will launch the program that is currently on the processor. The preset shown on the left is for 1 or 2 Goliath XD being fed a mono or LFE signal. Adjustments to the processor can be made to “Out 1 Sub L" and "Out 5 Sub R" when using a second subwoofer. The preset shown on the right is for 2 Goliath XD within a Whisper XD system.
Wave Launch Processor Making a boost with the parametric EQ In this example, we have selected Parametric EQ 2 (PEQ2) by clicking in its box, which will turn red to indicate your selection. Once highlighted, locate the blue boxes with up and down arrows, at the bottom of the interface. These arrows are used to increase or decrease the gain, frequency and Q of the selected parametric EQ. This column shows a 4.00 dB boost at 41 Hz with a Q of 6.551.
Wave Launch Processor Making a cut with the graphic EQ In this example, we have selected Graphic EQ 8 by clicking in its box which will turn red to indicate your selection. Once highlighted, locate the blue boxes with up and down arrows, at the bottom of the interface. These arrows are used to increase or decrease the gain of the selected graphic EQ. This column shows a 4.00 dB cut at 100 Hz. Only gain is adjustable in the graphic EQ section because graphic equalizers have a fixed frequency and Q.
Wave Launch Processor Adjusting using the EQ plot Adjustments made to both the parametric and graphic EQ are reflected in the graph occupying the upper portion of the screen. You can select them by clicking on their number, and dragging up to boost, and down to cut. Dragging to the left decreases the frequency, while dragging to the right increases the frequency. Recommendations Boosts greater than 6 dB can result in ringing, driver overload, or mechanical buzzing.
Fine Tuning Adjusting Goliath XD Gain: This will allow you to adjust the volume level played by the subwoofer. It only controls the subwoofer level, not the level of any of the other loudspeakers in the system. Be sure to adjust the Gain in the row corresponding to your subwoofer. Filter: Clicking this button allows you to access the EQ capabilities of the subwoofer. The crossover point and slope can also be adjusted on the right via the X-Hi/LPF section.
Designer’s Notes (From Bill Dudleston) •Goliath XD is a carefully engineered subwoofer, capable of integrating with the finest speakers. • Unlike many woofers that suffer from overshoot, Goliath XD applies a special EMF countering circuit, which increases power handling and radically reduces low frequency distortion. • An enormous stacked magnet structure is custom fabricated to provide excellent sensitivity. This unit is bolted in compression to secure nearly 80 lbs. of motor structure.
