Genelec 1094A and 1092A Subwoofers

General Description

The Genelec 1094A and 1092A active subwoofers are powerful low frequency loudspeakers, incorporating all the amplifier and crossover electronics needed to combine them with other loudspeakers and amplifiers.

Drivers

The 1094A contains a single 385mm (15") long throw cone driver, housed in a 110 litre vented cabinet. A cavity over the driver boosts the drivers efficiency and acoustically attenuates possible distortion components. The 1092A utilises two 210mm (8") cone drivers, housed in a 55 litre vented cabinet, and employs driver front loading.

Crossovers

The 3+1 channel active crossover within the amplifier unit filters the low and high frequency components of the

three front channels, dividing the input signals between the subwoofer and the main monitors. A separate subwoofer input connector allows for complete compatibility with digital 5.1 channel surround sound systems.

The crossover filter also provides calibrated ‘Bass Roll-off’ and ‘Phase’ controls, minimising the effects of the room on the performance of the subwoofer.

Amplifiers

The amplifier unit is mounted in the rear of the cabinet on quick release vibration isolators to ensure rattle free operation and long term reliability. The 1094A and 1092A amplifier output powers are 400W and 180W respectively. The amplifiers incorporate special driver protection circuitry for driver overload protection.

Installation

Before connecting the audio signals, ensure that both the subwoofer and the main monitors are switched off. Check that the subwoofer voltage selector switch is set to the correct voltage and that the correct fuse for that voltage is fitted.

Audio connections to the subwoofer are made via balanced XLR connectors. Signals from the source are fed into the subwoofer input connectors and signals for the main monitors are taken from the subwoofer output connectors. Once all connections have been made, the subwoofer and main monitors are ready to be powered up.

Setting the Input Sensitivity

The subwoofer requires input sensitivity alignment to the mixing console or other source to obtain a correctly balanced system. The input

sensitivity control is located on the rear panel of the subwoofer. An input voltage of -6dBu with a -6dBu input sensitivity setting will produce 100dB SPL @ 1m. To obtain a 110dB SPL output an input voltage of +10dBu is required when the input sensitivity is set to 0dBu.

Setting the Bass Roll-Off Switches

The acoustic response of the subwoofer may have to be matched to the characteristics of room in which it will be used. To adjust the subwoofer to match these characteristics use the ''Bass Roll-off' control switches located on the rear panel of the subwoofer. Table 1 provides some suggestions for the 'Bass Roll-off' switch settings. When both roll-off switches are 'off', a flat anechoic response results.

1092A, 1094A specifications

The Genelec 1092A and 1094A are prominent models in Genelec's line of high-performance studio monitors. Designed for professional audio applications, these monitors offer exceptional sound quality and a range of advanced features that make them ideal for studio environments.

The Genelec 1092A is a compact monitor, featuring a 4-inch woofer and a 0.75-inch tweeter, which together provide a frequency response of 67 Hz to 25 kHz. This model is particularly well-suited for small studio spaces where high-quality sound reproduction is critical, yet physical space is limited. The 1092A employs Genelec's directivity control waveguide technology, which helps achieve a smooth and consistent frequency response across various listening positions.

In comparison, the Genelec 1094A is a larger monitor with an 8-inch woofer and a 1-inch tweeter, resulting in a broader frequency response down to 45 Hz. This extended low-frequency capability allows the 1094A to deliver rich bass and provides a more impactful listening experience in larger rooms or for genres that demand a deep low end.

Both models feature Genelec's innovative Minimum Diffraction Enclosure (MDE), which minimizes diffraction effects and provides an accurate representation of the audio signal. This unique design is part of what sets Genelec monitors apart, enhancing their clarity and precision, even at high volumes.

The 1092A and 1094A also utilize a built-in amplification system that consists of high-performance class D amplifiers. These amplifiers are specifically designed to match the drivers’ characteristics, ensuring optimal performance while maintaining efficiency. Moreover, both models include advanced signal processing capabilities, including room response controls that allow users to tailor the monitors’ sound to suit their specific room acoustics.

Additionally, Genelec has integrated eco-friendly technologies in these monitors, featuring energy-saving power management systems that automatically switch to standby mode after a period of inactivity. This approach not only reduces energy consumption but also reflects the brand's commitment to sustainability.

In summary, the Genelec 1092A and 1094A studio monitors are engineered to deliver outstanding audio performance, showcasing a combination of innovative technologies, commitment to quality, and user-friendly features. Whether in a small home studio or a large professional environment, these monitors provide precise sound reproduction that meets the demanding standards of today's audio professionals.
