Ready-to-Place Bass

The Earthquake Sound FF10 is a single 10 inch powered subwoofer built for listeners who want deeper low-end without a separate amplifier rack. Its front-firing driver and slot port direct energy straight into the room, so placement near a wall or corner stays flexible. The integrated 400 Watt Class A/B amplifier keeps the signal path short and the enclosure compact. Home-theatre fans and stereo enthusiasts alike can add weight to movies and music without rearranging furniture.

Variable Crossover Control

A 12 dB per octave filter lets you set the handoff point anywhere from 40 Hz to 180 Hz, matching the subwoofer to satellites of almost any size. Turn the front-mounted knob until the bass blends seamlessly with your main speakers. The same circuit also provides a 0 to 180 degree phase shift so you can align timing with the rest of the system. No external processor or menu diving is required.

Simple Signal Chain

Low-level RCA inputs accept a pre-amp or AV receiver subwoofer output, while high-level terminals connect directly to speaker-level feeds from an integrated amp. RCA line-through outputs pass the untouched signal onward to another subwoofer or recorder. Automatic signal detection powers the unit on when audio appears and returns it to standby afterwards, saving energy without a remote trigger wire. Status LEDs confirm the current state at a glance.

Questions about this item

How loud and deep will the 400 watt amplifier actually play in a typical living room?

The built-in 400 watt Class A/B amplifier drives the 10 inch driver through a front-firing slot port, delivering strong output for music and movies in medium-sized rooms.

What does the 12 dB per octave filter ranging from 40 Hz to 180 Hz control?

It sets the upper frequency limit where the subwoofer hands off to your main speakers, adjustable between 40 Hz and 180 Hz with a 12 dB per octave slope.

How much floor space and clearance does the front-firing cabinet need?

The front-firing design and single slot port mean you only need room for the cabinet itself plus a few centimetres in front for the port to breathe; no rear-wall clearance is required.
