It is a standalone driver, not a complete enclosed subwoofer. Its dual voice coil provides two final load-wiring options.<\/p>\n<h2>Design and intended use<\/h2>\n<p>This model is engineered to produce high sound pressure levels in <strong>SPL<\/strong> competitions. The high-permeability magnetic plates are designed to maintain a stable, even magnetic flux. An enlarged magnet helps control the moving assembly when the driver is operating at high excursion.<\/p>\n<p>The basket and magnetic assembly are bonded with a special epoxy adhesive. This joint is also damped. The specified <strong>Xmax excursion<\/strong> is 3.2 cm, so the installation must provide enough clearance for the driver to move freely.<\/p>\n<p>The stated <strong>87.8 dB sensitivity<\/strong> does not include a measurement method or reference level. It should therefore not be compared directly with sensitivity ratings measured under different conditions.<\/p>\n<h2>Voice-coil wiring<\/h2>\n<p>The driver has two 2-ohm voice coils. Wiring them in parallel produces a <strong>nominal 1-ohm load<\/strong>. Wiring them in series produces a <strong>nominal 4-ohm load<\/strong>.<\/p>\n<p>The selected wiring arrangement must suit the amplifier\u2019s stable operating range. Both coils must receive the same signal and be connected with matching polarity. Incorrectly wired coils may move in opposite directions, reducing the overall sound pressure level.<\/p>\n<p>The <strong>500 W RMS<\/strong> rating describes continuous power handling. The <strong>1000 W peak dynamic power<\/strong> rating applies to brief signal peaks and should not be used as a target for continuous amplifier output.<\/p>\n<h2>Installation and tuning<\/h2>\n<p>Installation requires a <strong>35.6 cm diameter cut-out<\/strong> and at least <strong>18.1 cm of mounting depth<\/strong>. Allow additional room for the magnetic assembly, cable bends and unrestricted cone movement. The mounting surface must be rigid enough not to move with the driver.<\/p>\n<p>This driver requires a separate enclosure. Enclosure volume, construction and any bass-reflex tuning will determine the final frequency response. Specific enclosure parameters are not provided for this model, so an enclosure should not be selected using data from another ASY-series model.<\/p>\n<p>Frequency limiting, level and phase should be adjusted through the connected amplifier or audio processor. Begin with low gain and a low-pass filter (LPF). Match the filter cutoff to the operating range of the other speakers in the system.<\/p>\n<p>Compare different enclosure orientations at the SPL measurement position inside the vehicle. If the equipment allows phase adjustment, test both settings under identical conditions. Keep the position that delivers the better result in the specific vehicle.<\/p>\n<h2>Technical specifications<\/h2>\n<table>\n<tbody>\n<tr>\n<td><strong>Model<\/strong><\/td>\n<td>Audio System ASY-15<\/td>\n<\/tr>\n<tr>\n<td><strong>Type<\/strong><\/td>\n<td>Dual-voice-coil subwoofer driver<\/td>\n<\/tr>\n<tr>\n<td><strong>Intended use<\/strong><\/td>\n<td>SPL competition audio systems<\/td>\n<\/tr>\n<tr>\n<td><strong>Nominal size<\/strong><\/td>\n<td>15 inches<\/td>\n<\/tr>\n<tr>\n<td><strong>Sensitivity<\/strong><\/td>\n<td>87.8 dB; measurement conditions not provided<\/td>\n<\/tr>\n<tr>\n<td><strong>Impedance<\/strong><\/td>\n<td>Two 2-ohm voice coils<\/td>\n<\/tr>\n<tr>\n<td><strong>DC resistance Re<\/strong><\/td>\n<td>1.9 ohms; measurement configuration not specified<\/td>\n<\/tr>\n<tr>\n<td><strong>Resonant frequency Fs<\/strong><\/td>\n<td>34.8 Hz<\/td>\n<\/tr>\n<tr>\n<td><strong>Power handling<\/strong><\/td>\n<td>500 W RMS<\/td>\n<\/tr>\n<tr>\n<td><strong>Peak dynamic power handling<\/strong><\/td>\n<td>1000 W<\/td>\n<\/tr>\n<tr>\n<td><strong>Xmax<\/strong><\/td>\n<td>3.2 cm<\/td>\n<\/tr>\n<tr>\n<td><strong>Mounting depth<\/strong><\/td>\n<td>18.1 cm<\/td>\n<\/tr>\n<tr>\n<td><strong>Mounting diameter<\/strong><\/td>\n<td>35.6 cm<\/td>\n<\/tr>\n<tr>\n<td><strong>Magnetic plates<\/strong><\/td>\n<td>High magnetic permeability<\/td>\n<\/tr>\n<tr>\n<td><strong>Magnet<\/strong><\/td>\n<td>Enlarged for control at high excursion<\/td>\n<\/tr>\n<tr>\n<td><strong>Basket and magnetic assembly joint<\/strong><\/td>\n<td>Bonded and damped with a special epoxy adhesive<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>FAQ<\/h2>\n<h3>Is this a complete enclosed subwoofer?<\/h3>\n<p>No. It is a standalone 15-inch driver that must be installed in a suitable enclosure and connected to an amplifier.<\/p>\n<h3>How should both voice coils be connected?<\/h3>\n<p>The coils can be wired in series or parallel. Both must be connected with matching polarity and receive the same audio signal.<\/p>\n<h3>How should I choose an amplifier?<\/h3>\n<p>Choose according to the intended final load and RMS power rating. The amplifier must operate reliably with the selected load, and its gain must be adjusted correctly.<\/p>\n<h3>Where should I begin when tuning the system?<\/h3>\n<p>Start with the gain turned down and set the low-pass filter (LPF). Increase the level gradually while monitoring distortion and driver excursion.<\/p>\n<h3>How should I choose the enclosure orientation in a vehicle?<\/h3>\n<p>Compare several enclosure orientations under the same measurement conditions. The shape of the vehicle interior can change the result even when all other settings remain unchanged.<\/p>\n<h3>Can the sensitivity be compared directly with other models?<\/h3>\n<p>Only when the measurement method and reference level are the same.
