Powerful, standalone sound that flexes to meet your coverage needs — the Bose F1 Model 812 is a 1000-watt, full-range loudspeaker featuring Bose Flexible Array technology. At the heart of the F1 is a 12-inch woofer nested behind an array of eight high-output drivers. These nine speakers are supported by a lower crossover point than conventional loudspeakers — to give full voice to your sound and deliver clearer, more natural vocals and midrange clarity, even at high volumes. And you control the vertical coverage pattern. So, wherever you’re playing, you can adapt the PA to match the room. With the Bose F1 Model 812, your sound stands alone.

Flex Array Shapes

Straight Pattern

Use the straight pattern when the audience is standing and their heads are approximately at the same height as the loudspeaker.

Reverse-J Pattern

The reverse-J pattern is good for an audience in raked seating that starts at loudspeaker height and extends above the top of the loudspeaker.

J Pattern

The J pattern works well when the loudspeaker is up on a raised stage and the audience is seated below on the floor.

C Pattern

Use the C pattern for raked seating in an auditorium when the first row is on the floor with the loudspeaker.

    What is the F1 Model 812 system and what makes it different from other portable PA systems?

    The Bose F1 Model 812 12” 1000-watt powered loudspeaker is the first powered loudspeaker that delivers the benefits of an adjustable array in a portable system package. Its unique flexible baffle allows you to tailor the loudspeaker’s vertical coverage to a wide variety of listening environments. Simply push or pull the array into position to create “Straight,” “C,” “J” or “Reverse J” coverage patterns. Once set, the system automatically updates the EQ to maintain optimum tonal balance for each coverage pattern. So whether you’re playing at floor level, on a stage, or facing raked seats or bleachers, you can adapt your PA to the room.

    Engineered with an array of 8 high-output drivers, a high-powered 12" woofer and a lower crossover point, the loudspeaker delivers full-range, high-SPL performance while maintaining vocal and midrange clarity that’s dramatically better than conventional loudspeakers.

    The Bose F1 subwoofer packs all the power of a larger bass box into a more compact design that’s easier to carry and fits in a car. A mounting stand for the loudspeaker is stored right in the body of the subwoofer, making setup fast and easy. The stand even includes cable channels to neatly hide wires.

    The loudspeaker and subwoofer combined deliver 2,000 watts of power, so you can fill nearly any room with sound.

    And now getting there is easier, too. The loudspeaker and subwoofer feature strategically-placed handles for easy transportation.

    How is this different from a conventional PA?

    Current popular powered loudspeakers are standard 2-way designs consisting of a single horn-loaded compression driver for high-frequency reproduction and a single woofer for mid and low-mid frequency output.

    Since the Bose F1 Model 812 loudspeaker has an array of 8 high-output drivers, mid/high-frequency response is much cleaner and less harsh-sounding when compared to a traditional horn.

    Characteristically, horns have a fixed output pattern that isn’t adaptable to typical performance spaces. These fixed-pattern loudspeakers are commonly positioned on pole mount stands where high-frequency content is projected over listeners’ heads, making vocal intelligibility difficult.

    The Bose F1 Model 812 flexible array is quite useful for quickly and easily adjusting the loudspeaker’s coverage for a variety of performance and listening spaces, ensuring quality reproduction without the need for complex placement.

    How does the flexible array work?

    The 8 drivers on the F1 Model 812 flexible array are mounted on a specially designed flexible baffle that is hinged in two locations. When the array position is changed, the loudspeaker’s internal EQ automatically changes according to the array’s positon: “Straight,” “C,” “J” or “Reverse J.” This allows the loudspeaker to maintain tonal balance no matter which position is used.

    Does the F1 Model 812 have a woofer?

    Yes. The high-output 12" woofer is mounted behind the flexible array.

    Can I use the F1 Model 812 with a standard speaker stand?

    Yes, there is a pole cup on the bottom of the enclosure that is compatible with standard 1 3/8 inch diameter (35mm) speaker stands.

    What is the recommended subwoofer?

    For best performance, we recommend using the Bose F1 subwoofer. However, other powered subs can be connected to the F1 Model 812 loudspeaker.

    What is the F1 subwoofer?

    The F1 subwoofer is a compact bass module designed for use with the F1 Model 812 loudspeaker. Its powerful amplifier and dual drivers produce bass as much as subs nearly double its size.

    The F1 subwoofer features:

    • 2 X 10" high-excursion drivers
    • 1000 watts
    • 2 x input channel with XLR, 1/4" combo connector
    • 2 x XLR balanced line out
    • Polarity reverse switch
    • HPF enable


    How many F1 subs can you connect to an F1 Model 812 loudspeaker?

    We recommend 1 sub per F1 Model 812 loudspeaker. However, you can connect as many as needed.

    Can the F1 systems be used with Bose L1 systems?

    Yes. Bose L1 systems can be used in conjunction with the F1 Model 812 loudspeaker as a supplemental fill or stage monitor.

    Can it be used with the ToneMatch mixers?

    Yes. The F1 system is compatible with the T4S and T8S mixers.

    These mixers are powerful, multichannel audio devices designed for musicians to use Bose portable pro loudspeaker systems. They include our largest library of ToneMatch presets, proprietary EQ, a complete suite of studio-class effects and processing, and five channel inputs.

    What sources can I plug into the mid/high?

    The rear panel of the F1 Model 812 loudspeaker is equipped with XLR/TS combo jacks, a ¼" instrument jack and stereo RCA inputs. When an external mixer is not used, a wide variety of instruments or sources can be connected directly. Common sources include:

    • A dynamic microphone
    • An acoustic instrument with a pickup system
    • Electronic keyboard
    • Electric bass guitar

    Yes. The F1 Model 812 loudspeaker and F1 sub are ideal for DJs that want high power and sonic clarity in a portable system. The F1 subwoofer’s compact design and high capability remove the need for transporting subwoofers twice their size. Plus, the integrated stand eliminates ugly tripod bases that expose hanging wires and create tripping hazards.
