Woofer Break-In
IMPORTANT NOTE - WOOFER BREAK IN: After completing the wiring, break in your subwoofer properly. Play the subwoofer at low to medium volume with music that has good low-frequency information for approximately 20 hours to condition it before turning up the volume. This will improve the subwoofer's performance and lifespan.
Recommended Enclosures
The following table provides recommended enclosure volumes and external dimensions for the HS102/4D and HS122/4D subwoofers, calculated using 3/4" MDF. Ported enclosure details are listed as N/A, indicating that specific slot port dimensions are not provided in this manual.
| SUBWOOFER SIZE | SEALED ENCLOSURE Volume (net int.) | SEALED ENCLOSURE External Dimensions Width x Height x Depth | PORTED ENCLOSURE Volume (net int.) | PORTED ENCLOSURE External Dimensions Width x Height x Depth | PORTED ENCLOSURE Slot Port Internal Dimensions Port Width x Port Height x Port Length | PORTED ENCLOSURE Port Extension Length "PE" |
|---|---|---|---|---|---|---|
| HS102/4D | 0.65 ft³ (18.2 litres) | 22" x 12" x 6.75" (406mm x 305mm x 162mm) | N/A | N/A | N/A | N/A |

A diagram illustrates a typical subwoofer enclosure with dimensions labeled. A frequency response graph (SPL vs Freq) is also presented, showing how sound pressure level (dB SPL) changes with frequency (Hz) for a sealed box. Power handling is indicated with color-coded areas:
- MINIMUM RMS POWER (100W BLACK AREA): This lower amount of power will increase the longevity of the woofer, but will decrease the amount of output volume.
- RECOMMENDED RMS POWER (200W GREEN AREA): This is the optimum amount of power to provide the perfect balance of output volume and woofer longevity.
- MAXIMUM RMS POWER (300W RED AREA): This is the maximum amount of power the woofer is designed to operate safely under. Only a moderate volume increase is gained (< 7dB) at this higher power level. Operating beyond this power level will void your warranty.
