Description

The Earthquake Sound FF Series combines bass performance and clean black-ash cosmetics at a budget-friendly price. Compact cabinet dimensions and front-firing woofers support integration into cabinetry. With three models to choose from, the FF series gives installers a practical option for projects where budget and cabinet fit are key considerations.

The FF6.5 is the smallest of the series. This self-powered 150W subwoofer achieves top-notch bass quality in the smallest of spaces.

  • Front-Firing Design: The forward-facing 6.5" woofer provides flexible placement on any surface without requiring additional clearance beneath the cabinet.
  • Big Bass, Small Footprint: Its compact cabinet (~9.9" H x 7.7" W x 14.25" D) makes it especially well-suited for apartments, condos, bedrooms, small theater rooms and other installs where a larger subwoofer isn't as practical.
  • Comes complete with removable grill
  • Transmission-line Design: The FF6.5 uses a transmission-line cabinet, a design that requires substantial engineering and a cabinet construction investment.

Transmission Line • Slot-Port Loading

The third generation Earthquake FEA computer-modeled bass Slot-Port loading increases the output of the powerful woofer/amp combo. The new Slot-Port provides more port volume than possible with traditional tubular port loading resulting in radically increased low frequency output. Since it is not a tubular device, it can bend at optimum angles reducing cabinet size making the subwoofer both powerful and aesthetic. It also routes laminar airflow across the aerodynamically shaped internal amplifier heat-exchangers.

This forced flow cooling technique enables the FF subs to operate at continued high levels, even if fully built-in. The Slot-Port is an integral part of the subwoofer and serves as a cross brace making the cabinet very strong and resonance free.

The FF6.5 takes the Slot-Port design a significant step further by fusing the Slot-Port with an advanced reflex apparatus. This new technology merges a quarter-wavelength transmission line with a variable cross-section folded-horn.


This novel synthesis of technologies yields an acoustic reflex device with unsurpassed efficiency. Resulting in a massive boost to low frequency output, empowering the FF6.5 to rival ordinary designs with woofers up to 10 inch.
