If you have been watching this subwoofer. This is the lowest range it has touched recently.

What You're Getting

The Earthquake SUB-80X packs a 300W peak Class AB amplifier into a compact down-firing 8-inch enclosure. The wide-edge Santoprene surround and 48 oz high-density magnet improve durability and excursion, while the 2-inch high-temperature voice coil handles extended playback without thermal issues. A flared front-facing port works with the down-firing woofer to balance depth and impact. Connectivity is versatile enough to pair with most satellite speakers, so integration into an existing system is straightforward.

Who This Is For

Best for: home theater builders who want a dedicated subwoofer in a medium-sized room without the footprint of a larger unit. Also a strong fit for stereo setups that lack low-end punch.

Skip this if you need sub-30Hz extension for serious home theater LFE channels - an 8-inch driver has limits, and the Earthquake plays best in the upper bass range where it delivers tight, controlled output.

Final Verdict

Below its 30-day average by a solid margin and paired with a capable amp, the SUB-80X is a smart pickup for anyone upgrading from a budget sub or filling a gap in a 2.1 or 5.1 system. If you need bass that hits clean rather than loud. This is the price to move on.
