Audio System ASY-10 Subwoofer
130,00 €
Audio System ASY-10 is a 10-inch subwoofer for a competitive car audio SPL system. Its dual 2-ohm voice coils allow the wiring arrangement to be selected according to the amplifier load. The 500 W RMS rating helps with continuous-power planning. The 1000 W peak dynamic rating describes a short-duration level rather than a continuous load. Installation requires a 228 mm cutout and 146 mm of mounting depth.
Audio System ASY-10 is a 10-inch subwoofer designed for competitive car audio SPL systems. It features dual 2-ohm voice coils and a stated 500 W RMS power rating. This is a standalone driver, so it requires an enclosure, an external amplifier, and suitable system filtering.
Who Is This Model For?
This model is intended for buyers building a competition-focused SPL system. It is not a complete powered subwoofer enclosure. The main considerations are the voice-coil wiring arrangement, the resulting amplifier load, and an enclosure designed for the specific SPL objective.
Construction
The motor assembly uses high-permeability magnetic plates and an enlarged magnet. The basket and motor are bonded and damped with special epoxy adhesives.
The larger magnet assembly requires sufficient clearance inside the enclosure. For physical installation, allow for the 228 mm cutout diameter and 146 mm mounting depth.
Voice-Coil Wiring
The dual 2-ohm voice coils provide more than one possible final amplifier load. The resulting impedance depends on the selected wiring arrangement and must remain within the amplifier’s permitted operating load.
Both coils must be connected using one consistent wiring scheme while maintaining correct polarity. Choose the amplifier according to its stability at the calculated final load and its continuous output power at that load.
Installation and Enclosure Design
The front baffle and internal clearance must accommodate both the basket and the magnet assembly. Leave adequate room for the terminals and wiring without pressing the cables against the rear wall of the enclosure.
The 38.8 Hz resonant frequency is not the lower frequency limit of the finished system. Final performance depends on enclosure volume, enclosure type, tuning, and the acoustic characteristics of the vehicle cabin.
The measurement method used for the 3.2 cm Xmax figure is not specified. This value should therefore not be compared directly with excursion figures obtained using different measurement methods.
Power Assessment and Initial Setup
The RMS rating is the main reference when selecting suitable continuous amplifier power. The peak dynamic rating describes a short-duration level and should not be treated as a continuous operating target. Test conditions have not been provided for either power figure.
No measurement method is given for the 83.8 dB sensitivity figure. On its own, this value is not sufficient for an objective comparison of efficiency between different subwoofer models.
The driver itself has no system controls. Set the low-pass filter, gain level, and phase, where available, through the amplifier or audio processor.
Begin with a low gain setting and increase it gradually. Adjust the filter point so the subwoofer integrates with the front speakers. Compare the available phase settings from the driver’s listening position.

FAQ
Is this a complete subwoofer enclosure?
No. It is a standalone driver that requires a suitable enclosure, external amplifier, wiring, and system filtering.
How should the two voice coils be connected?
Connect both coils according to the manufacturer’s wiring diagram. Before making the connection, calculate the final load and confirm that it is compatible with the amplifier.
What type of amplifier should I choose?
Consider the amplifier’s continuous output power at the selected final impedance. Do not use the subwoofer’s peak power rating as the target for continuous amplifier output.
How should I choose an enclosure?
The mounting dimensions determine whether the driver will fit physically, but they do not specify the required acoustic volume. The enclosure type and tuning must suit the particular SPL objective.
Does the subwoofer have filter and phase controls?
No. These settings are made through the amplifier or audio processor when the relevant functions are available.
Which direction should the subwoofer face in the vehicle?
Test several enclosure orientations in the same cabin position. For an SPL project, measurements taken under consistent conditions provide the most reliable comparison.
