Bose F1 Powered Subwoofer

1,000 watts of power packing all the performance of a larger bass box into a more compact design that’s lighter and easier to carry.
Line output EQ can be set to a high-pass filter or full range, allowing for easy crossover selection when used with a main loudspeaker.
Two 10-inch high-excursion drivers built into a compact enclosure that’s light and easy to transport.
F1 Model 812 extension bracket integrated into the subwoofer can be raised and lowered, allowing the F1 Model 812 Flexible Array loudspeaker to be safely mounted on the subwoofer, eliminating the need for a conventional pole mount or tripod stand.
Polarity switch with selections for NORM and REV. Reversing polarity allows for easy correction of low-frequency overlap between the main loudspeaker and subwoofer.

Gelcore cabinet construction reduces higher frequency cabinet noise. P2P (Point to Point) internal bracing stiffens the cabinet to minimise lower frequency vibrations..
Ground-up mid/bass and tweeter driver design for increased power handling. High-frequency driver is fully hermetically sealed and mechanically isolated (floating) from the front baffle to protect from internal resonances from the mid/bass driver..
Isolation suspension base eradicates unwanted external and internal vibrations. Crossover design is mounted on the isolation base, to minimise any microphonic pick up and away from electro-magnetic fields radiated by the drive units..

Full Range Woofer Loudspeaker is a 5"/6"/8" set, 4 ohm speaker complete range of amplifier, subwoofer speakers with an amazing frequency and loudness range.
provides amazing sound from low to very high volumes ..
A full-range woofer consists of a single driver element or red voice coil group, in the shape of a radiating dome dust cap, which is acoustically active. In most speaker drivers, the construction of this dust cap is relatively acoustically inert. Comes in the form of a small cone, claimed to improve dispersion at higher frequencies..
Has good low frequency and high frequency response - leave lower frequencies for subwoofers or special cabinet designs to handle/boost low frequency boost. Full range with good sensitivity (low frequency) and a light voice coil (high frequency) - these speakers usually use stronger magnets than usual, which increases sensitivity which reduces power requirements at low frequencies as well as allowing for a lighter voice coil..
The core has a copper ring that reduces third harmonic distortion by eliminating the generation of induced currents in the pole pieces. Also allows to implement the system according to the configuration "Mid-Treble-Mid", "Low-Mid-Treble" or possibly "Twin Peaks". It is equipped with a paper me....
