Frequently Asked Questions - MX10D4 PHOENIX GOLD

What is the impedance of the Phoenix Gold MX10D4?

The MX10D4 has dual 4-ohm voice coils, allowing wiring options for 2 ohms (parallel) or 8 ohms (series).

How much RMS power can this subwoofer handle?

It is rated for 400 watts RMS with an 800-watt peak.

What enclosure type is recommended for the MX10D4?

For best performance, use a sealed enclosure (0.8-1.2 cu ft) or a ported enclosure (1.5-2.0 cu ft) tuned to 35 Hz.

What is the mounting depth of this subwoofer?

The mounting depth is 5.5 inches (140 mm), fitting many standard boxes.

Can I wire the MX10D4 to 1 ohm?

Yes, by wiring both coils in parallel, you achieve a 2-ohm load per sub, not 1 ohm. For a single sub, the lowest impedance is 2 ohms. With two subs, you can reach 1 ohm.

What amplifier should I use?

Use a mono amplifier that delivers 400-600 watts RMS at 2 ohms for optimal performance.

How do I clean the subwoofer?

Wipe the cone and surround with a soft, damp cloth. Do not use chemical cleaners or water jets.

What is the frequency response of the MX10D4?

The subwoofer reproduces frequencies from 25 Hz to 250 Hz, ideal for deep bass.

Does the MX10D4 come with a grille?

No, a grille is not included, but it can be purchased separately for protection.

Is the MX10D4 suitable for a sealed or ported box?

It works well in both. A sealed box offers accurate bass, while a ported box provides higher output around the tuning frequency.
