The 600-watt maximum rating provides additional short-duration power handling.
Dual 4-ohm voice coils offer flexible wiring configurations for compatible audio systems.
🎵 Precision-Engineered Sound Quality
The non-pressed paper cone delivers natural low-frequency character and detailed musical reproduction.
A composite foam surround supports smooth, controlled cone movement during demanding listening sessions.
The rigid steel basket provides structural stability and helps minimize unwanted resonance.
Its high-temperature voice coil supports reliable performance with properly configured amplification.
A one-piece dust cap reinforces cone rigidity for consistent bass response.

⚙️ Flexible Dual Voice Coil Wiring
Connect both 4-ohm voice coils in parallel for a nominal 2-ohm load.
Alternatively, connect the coils in series for a nominal 8-ohm load.
These options simplify matching the driver with compatible monoblock amplifiers.
Always confirm amplifier stability and output before selecting the final impedance.
Both voice coils must be connected correctly during normal operation.

The EPICX8D4 supports sealed and ported enclosure designs.
A sealed enclosure offers controlled bass response while conserving installation space.
AudioControl publishes an ideal sealed internal volume of 0.65 cubic feet.
A ported enclosure can provide stronger output near its designed tuning frequency.
The recommended vented design uses 0.71 cubic feet of net internal volume and 40 Hz tuning.
Its 4.1-inch mounting depth makes the driver suitable for many custom compact enclosures.
