Let Your Music Take Flight with BenQ treVolo


Let Your Music Take Flight with BenQ treVolo Now, with the world's first portable Bluetooth® speaker with Electrostatic Technology, the BenQ treVolo enables astonishing clarity and absolute precision for your favorite vocal and acoustic music.

treVolo speaker


"tre" is the sum of three E's: Electrostatic, Enjoyment and Everywhere. When fused with the Italian word "Volo", which means flight, treVolo is formed to bring to life BenQ's brand promise and belief – let your music take flight to new heights of audio satisfaction.

BenQ Electrostatic Diaphragm Technology

Unconventionally designed with BenQ's Electrostatic Diaphragm Technology, treVolo incorporates a quad-amplified design that utilizes two electrostatic panels with dual bass drivers and passive radiators. The clarity of each note is ensured by the highest reproduction accuracy from the original audio source, resulting in natural and true sound. What's more, the broadened sound range immerses you with a whole new experience of audio dynamics and realism.

The design of the electrostatic panels enables sound to be projected in front and behind the speaker to enhance sound projection over a large surface area for broadened sound range, just the way a live instrument such as a violin projects sound throughout the room – not just in one direction.

Spacious Natural Sound

Electrostatic drivers emit clean sound forward and backward, so they have a more spacious, natural sound. Conventional full-range drivers emit sound only forward; resulting in rear driver projection to resonate inside the enclosure causing distortion.

Sound Reproduction

Vertical dispersion of the entire thin-film diaphragm offers bidirectional sound projection over a large surface area for a more detailed audio performance in just about any space.

Uses traditional cone drivers that may struggle to provide clear sound though the audio range.

Audio Distinctiveness

Quad amplified systems with active DSP crossovers provide seamless transitions from low to high ranges, enabling you to hear the details in your music.

Often use passive crossovers with more emphasis on bass tones, and with highs that can sound muddy.


Placement and Spatial Requirement

Sound is produced on both sides of the speaker, like a real instrument. This provides a spacious and natural sound.

Sound projects only in one direction from the speaker, thus limiting the natural sound stage effect.


Precision-Tuned Speaker & Quad Amplified Design

A precision-tuned speaker and quad amplifier design ensure precise bass performance while achieving balance and neutrality in the overall performance of mid- and high-range sounds. So clean, accurate sounds can be produced to please even the most demanding audiophile. Within the treVolo, the low frequencies driven by two high-quality, high-excursion 2.5-inch woofers, combined with passive radiators deliver crisp, accurate bass to 60Hz. In addition, each driver in the treVolo is powered by its own amplifier channel and uses an advanced DSP chip to smoothly transition from low to high frequencies.

When I unboxed the BenQ treVolo, I knew immediately that there was a different personality about this unit. The design and form of the speaker connection and the smooth metal housing really made me feel like I was holding something substantial.
The electrostatic wing design of the unit is unique and interesting. But I was quite curious about the tone because this was the first time I had seen an electrostatic speaker on any portable unit.
Of course, as I do with all new speakers, I decided to audition a few of my favorite albums on it to get a feel for how it handles sound and different genres of music. To do this, I always use stand-by albums that I’ve been listening to my whole life. First among these would be “Dark Side of the Moon,” by Pink Floyd.
Because my father came from London, I grew up listening to lots of British rock at home. For that genre, many audiophiles consider “Dark Side of the Moon” to be among the best analogue recordings from the classic rock era. From start to finish, the treVolo delivered great playback of this classic album.
It had balanced frequencies, but I noticed in particular that the midrange frequencies that are so signature in British rock, really came through nicely and represented the genre very accurately.
As a guitarist, I’m always noticing the guitar’s subtle nuances on recordings, and I’m aware of the details as they get played back on different systems. And I’m happy to say, David Gilmour’s guitar solos on the tracks Time, and Money, sounded amazing on the BenQ treVolo.
The second album I decided to demo on the BenQ treVolo was a jazz record by Miles Davis, called “Relaxin'.” This album is perfect for when you want to sit back, relax, and really fall in love with jazz.
The signature timbre of Miles's trumpet was crystal clear from the first song, “If I Were a Bell,” and the tone of his horn is easily distinguishable on the treVolo as one of the most classic voices in Jazz. The BenQ treVolo is really well suited for jazz playback at home.
Lastly, I wanted to get a feel for how current pop vocals would sound on the treVolo. So I put on some Maroon 5 because their catalog of hits represents current American pop genre, and their production is top-of-the-line for what the recording industry can produce for modern pop artists today.
Their latest single called “This Summer’s Gonna to Hurt…” showcases the song’s clear vocals, deep drums, and pulsing base. The playback of Maroon 5 on the treVolo tells me that this system can also handle the low frequencies with its central woofers, while remaining balanced by focusing the mids and high frequencies for vocal playback through the electrostatic wing speakers.
This separation of speakers based on frequency is key to the unit design, and allows for real sonic separation to be audible in the listening experience. The BenQ treVolo seamlessly fits together all the instruments of the band into a wide stereo field, and highlights the vocal in the upper middle frequencies. There was almost no distortion rate or muddiness, even at higher volumes.
As a composer and a producer, I always listen closely for the blend of instruments in a song mix. Is there space? Is there depth? Is there dimension? How do the frequencies and timbre of each instrument combine to mix melody and harmony, and become great recordings? These ideas are at the heart of any top grade recording and music production.
I was happy to find out that the BenQ treVolo handles these elements flawlessly, based on a wide variety of playback, while covering the different music genres in my collection.
I must say, I am deeply satisfied with the playback performance of the BenQ treVolo and it gave great performances of my favorite albums! Whether I’m in the mood for acoustic, jazz, vocals, or strings, the treVolo speaker clarity translates over a wide variety of genres.
