The Trillium technology makes the difference

The real highlight of the Turbo X is under the hood of the glossy cover. Overall, the Turbo X has three channels. Two are located to the right and left side parts while the third channel has been positioned centrally on the front. Each channel is powered by a 60 mm driver from the company’s parent company ADX which covers the entire frequency spectrum. In addition, there are another four bass drivers that are passively driven. Unfortunately, a frequency range for these isn’t available.

The large speaker offers an RMS output of 45 Watt and proves to be sufficient in larger rooms. The peculiarity of the Turbo X is how the three active channels are used. Here, they’re fused together with the Trillium algorithm. Despite the fact that we’re dealing with a single compact unit, a clear left and right distinction in audio can be heard. Of course this benefits the overall audio experience.

In order for the Trillium technology to be taken advantage of, the speaker should ideally be located in a corner of the room. The background is, of course, that two lateral drivers can radiate cross the walls diagonally resulting in a large sound field. Likewise, placing the device in the corner also helps improve low frequencies resulting in a bulkier sound. If the manufacturer can deliver on these promises, we’ll take a closer look below.

Sound Check

The Turbo X is for several reasons the most convincing, compact Bluetooth speaker. Using our reference song that we’ve used for many years, “Forgiven not forgotten” by the Corrs, we get a good idea of what’s going on as we’ve been using the same sample for numerous sound systems at all kind of price ranges.

Already at the first bars is it noticeable that the Turbo X offers significantly voluminous sounds. The playing of the violin at the beginning is clean resulting in neither a pointed nor unnatural experience. As the drums come into the picture we continue with a positive impression as a certain punch exist without it coming on too thick. The same applies later for the vocals of Andrea Corr which is pleasantly natural. At the same time the Turbo X highlights the smaller details that are so often swept under the carpet. Voices are clearly articulated, but never sounding strained or even annoying at high volumes.

Elsewhere the Turbo X continues to offer a convincing performance as the small Bluetooth speakers offers an extremely neutral, let certain level of playfulness. If the device is greeted with something more bass heavy the Turbo X offers a convincing performance as it’s not exaggerated like so many other smaller devices.

Interestingly of course is whether the Trillium technology can offer the user what was promised. The Turbo X can generate a pleasant big stage experience with basic right-left differentiation. But you shouldn’t expect to achieve the same effect, which is possible with two dedicated speakers. Those who prefer a sense of openness shouldn’t expect too much “surround” out of the device.

Those who prefer to listen to their music loud are in luck as the device reaches more than 100 dBA. In our tests the Turbo X proved to be really loud without sounding unpleasant.

Added Microphone

Thanks to a built-in microphone the Turbo X can also be used as a speakerphone. This worked well in our tests, as long as the speaker isn’t too far away.

Thanks to an internal battery you can run the Turbo X away from a power point with no difficulty. Riva quote the device as offering 26 hours at a volume of 75 dBA. In our test of the Turbo X the device worked well with even the volume increased slightly. Of course, the exact number of hours depends on numerous factors.
