The Earthquake Sound FF-10 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. The advanced design features coupled with rational manufacturing are keys to the FF lines unbeatable price and performance combination. All this boils down to the fact that the creation of the new FF subwoofers was no accident, rather the result of meticulous engineering building on a heritage of excellence.
The FF-10 not only utilises an advanced built-in 400-Watt Class “A/B” high efficiency power amplifier, but also has a front slot-port designed to work in tandem with the amplifier to produce deep, satisfying low levels of undistorted low, long and linear bass. With auto signal sensing, 0-180°phase shift and 40-180Hz crossover, the FF10 is your 'go to' sub when the budget is modest and the room size is modest.
But don’t let its price nor size fool you, this small sub can produce over 130dB peak SPL (includes room gain) from 25Hz to 125Hz. The high quality 10" driver 'coupled' with the clever design really beggars belief, resulting in a massive boost to low frequency output, empowering the FF-10 to rival ordinary designs with much larger woofers.
The FF-10 benefits further from low and high level inputs and outputs (RCA and Speaker Level), meaning that it is an adaptable product at home with 2 channel or multi-channel set-ups. This flexibility makes it perfect for any installation and cabling platform, so it will surely prove to be an adaptable performance driven custom installation stalwart for many years to come.
