Using your system

For realistic home theater sound

CAUTION: The Acoustimass® 15 Series II and Acoustimass 16 speaker systems incorporate an automatic protection circuit, which guards against most kinds of damage from electrical stress or overload. This circuit activates at high volume levels to reduce output, causing a slight decrease in volume. This is normal operation and indicates that power input may be exceeding safe levels. Sustained listening at these levels is not recommended.

Adjusting the LFE level

The LFE (low-frequency effects) level control on your powered Acoustimass module increases or decreases the relative level of low-frequency effects on movie sound tracks. Use it to regulate the presence of these underlying deep bass sounds. Use the “test tones” feature in your digital surround sound receiver to match the volume levels for each of the cube speakers. Then use the LFE control on the Acoustimass module to match the volume of the LFE channel to the cube speaker channels.

Adjusting the bass/room compensation level

This feature will allow you to fine-tune your system after you have placed the Acoustimass module in your selected location. If the room sounds “thin” or lacks bass, turn the BASS con- trol in a clockwise direction to increase the bass level of the module. If the room sounds “boomy” or has too much bass, turn the knob in a counter-clockwise rotation to reduce the bass level of the module. The factory or detent setting is appropriate for a majority of listening situations.

Setting your digital surround sound receiver

Your Acoustimass 16 or Acoustimass 15 Series II speakers are fully compatible with the output from digital surround receivers. Integrated Signal Processing assures full bass reproduction for all channels regardless of receiver settings. However, the following table suggests a set of recommended receiver settings. The cube speaker arrays should be set to LARGE in the receiver’s digital display menu. The LFE, or subwoofer, is set to ON. If applica- ble, the crossover value should be set to the lowest number possible, typically 80 Hz.

15, Acoustimass 16 specifications

The Bose Acoustimass 16 and 15 speaker systems stand as exemplary audio solutions designed to elevate the home theater experience. Renowned for their impressive sound craftsmanship, these systems utilize advanced technologies to provide immersive audio that captivates listeners.

One of the standout features of both models is the proprietary Acoustimass technology. This innovative design enhances low-frequency performance while minimizing distortion, delivering deep bass sounds that resonate throughout the room. The Acoustimass module works in tandem with surround speakers to create a rich, full-range audio experience that fills the environment with dynamic soundscapes.

The Acoustimass 16 system is composed of five satellite speakers along with the Acoustimass module. The satellite speakers are compact and can be easily mounted or placed on shelves, making them versatile for various room configurations. These speakers utilize advanced drivers to ensure clarity and detail, allowing users to hear every whisper of dialogue and the subtlest nuances in a film's soundtrack.

On the other hand, the Acoustimass 15 features a similar configuration but comes with four satellite speakers, making it ideal for smaller spaces without compromising sound quality. The modular design of both systems allows for easy integration with existing audio equipment, ensuring that users can upgrade their home entertainment setup without hassle.

Another notable characteristic of these systems is the Direct/Reflecting speaker technology employed in the satellite speakers. This engineering approach helps to replicate the natural ambiance of live performances by reflecting sound off walls and dispersing it throughout the room. This creates an enveloping audio environment, ensuring that every seat in the room feels like the sweet spot.

Additionally, both the Acoustimass 16 and 15 systems are compatible with most home theater receivers and amplification systems, making them a flexible choice for any audiophile. The sleek design of the speakers allows them to blend seamlessly into any decor, while the durable construction guarantees long-lasting performance.

In conclusion, the Bose Acoustimass 16 and 15 speaker systems deliver exceptional audio quality, with features that cater to both casual listeners and dedicated home theater enthusiasts. With their innovative technologies, meticulous design, and impressive performance, these systems are a worthy investment for anyone seeking to enhance their audio experience.
