Are Branded Speakers on a Projector Really Better?

In terms of the actual hardware innovations that took their portable projectors’ sound quality to a higher level, BenQ’s treVolo team implemented the following design changes:

To expand the sound and cover a wider spectrum of audio, BenQ’s portable projectors were equipped with 2.1 channel audio which complemented their full-range dual stereo speakers with a dedicated sub-woofer for added bass. A further breakdown of the differences between the traditional 2.0 channel audio and BenQ’s 2.1 channel sound is detailed below:

BenQ’s audio enhancements extend beyond the pure hardware design aspects. While normal portable projectors might deliver simple and unrefined sound, BenQ didn’t settle for a single audio profile for all scenarios and content types.

The custom digital signal processors, or DSP, on BenQ’s portable projectors were custom-tuned by the treVolo team to generate realistic, engaging audio in various situations and listening conditions. However, this doesn’t mean simple and rigid presets were used. BenQ audio experts turned to the field of psychoacoustics, which as the name implies refers to the psychological perception of audio and the physiological effects of sound. This has become a science of its own, with precise calculations to measure the impact of sound on different listeners based on distance from the speaker, relative angle, room conditions, and more. Broadly speaking, BenQ treVolo sound modes for portable speakers cover cinema, game, music, and sports, each one painstakingly developed with their own individual profile based on psychoacoustics principles and a lot of focus testing along the way.

What it all amounts to is a culmination of the years of experience and meticulous craftwork that the treVolo team distilled into the custom-design of BenQ’s top-flight portable projectors.

The end result of all this pain-staking work is a line of portable projectors that not only delivers pristine cinematic visuals – which BenQ is well known for – but also immerses the viewer in an audio experience that is not constrained by what might have traditionally been thought of as the limitations of a small form factor.
