For just $119.99, down from its list price of $225. That beats the 30-day average of $166.70 and the 90-day average of $150.16 by a wide margin.

This is one of the deepest cuts we have tracked on the PUMP-12, and the discount puts it at a price point that undercuts most 12-inch passive radiator alternatives by a amount.

What You're Getting

The PUMP-12 is Earthquake's patented dual 12-inch horn-loaded passive radiator module designed for sealed subwoofer enclosures in both home and car audio setups. Key specs include:

• Dual 12-inch horn-loaded passive radiators with polyether foam surrounds
• Anti-rocking dual suspension system for clean, distortion-free cone movement
• Horn-loaded neck design that increases effective speaker impedance
• Delivers up to +6dB of additional bass output without needing more amplifier power or enclosure volume
• Cutout dimensions: 5-1/2 x 12-3/4 inches; requires 9 x 14 x 14 inches of installation space; piston area of 226 sq. in.

This is not a standalone subwoofer. It is a passive radiator module that replaces a port or adds cone area to a sealed box. The horn-loaded design is what sets it apart from standard flat passive radiators, giving you more output per inch of cone displacement.

Who This Is For

Best for DIY car audio builders and home theater enthusiasts who want extra low-end extension from an existing sealed enclosure without buying a second amplifier or building a bigger box. If you are chasing single-digit hertz output or need a drop-in replacement for a damaged passive radiator, the PUMP-12 fits a very specific niche.

Skip this if you need a powered subwoofer or a complete enclosure ready to run.

Final Verdict

At $119.99, the PUMP-12 costs less than many single 12-inch passive radiators and delivers dual-driver output with a patented horn load that actually adds measurable SPL. If you are in the middle of a subwoofer build or tuning an existing sealed box. This is the price to lock in.
