Closer Examination

I was tempted to have a banana in the first photo for the memes, simply because there is nothing else like the TRETTITRE TreSound1 that I am aware of. This is a single-unit speaker that uses multiple drivers inside in a conical form factor to produce what the company claims is 360° surround sound. The design does resemble a mountain peak perhaps, although the use of the metal and lacquer on the outside in addition to the shiny nose may also prompt comparisons to tactical warheads. Indeed, the TreSound1 is larger than you think at 43 cm tall and having a 30 cm diameter at the base. It also weighs 6 kg by itself so I would not call this a portable speaker despite TRETTITRE wanting you to think otherwise. Indeed, there are some hilarious images on the product page of people using this outdoors even, but it's not even a battery-operated device! Given the use case and the design, the TreSound1 is best seen as a showpiece in your living room or office. This is also why it comes in four different color options and I have the "Majestic Mountain" version that goes with black lacquer and a gold finish to the steel trim. The "Green Hill" and "Flame Red" also have the gold metal trim and the "Snow Peak" goes with a more understated white and silver finish.

The lacquer finish is applied over wood in a similar manner as piano paint on, well, pianos among other things. This means you get a highly glossy finish that you may want to wipe periodically with a microfiber cloth. The company logo is seen towards the bottom on one view, albeit the conical form factor means you can just rotate the TreSound1 for a cleaner aesthetic. The grills in the larger steel trim allow for a closer look at the speakers inside through the mesh and the top section ends up providing user controls! Indeed, this is an actual knob that you can turn to switch on the speaker and then adjust the volume. At the very top is an indicator LED which comes in handy as we will soon see.


Don't go laying down the TreSound1 on its side in use as you'd be blocking some of the speakers, but doing so provides a better view of the construction of the set. There's a base which extends outwards slightly to help lift up the subwoofer placed at the base, which we now get a teaser of. The base is again made of thick steel in a durable black finish with more branding and some product specs listed here. There are also three long rubber pads to add friction against the resting surface although it's not like this 6 kg beast will just move on its own.


The side behind where the TRETTITRE branding is present is the logical back of the TreSound1 and here we see the metal base risen up slightly to expose a section that contains the wired inputs. There are are also screws here holding the base in place in the wood of the section above it, although your attention should be on the power input on the left, a 3.5 mm TRS wired input to the right, and a lightly recessed reset button in the middle you press for ~5-10 sec to reset the speaker. Realistically, you would only reset the TreSound1 if there is something off with its Bluetooth settings or pairings as it's not a smart speaker with any other functionality beyond playing music and controlling the output volume via the knob at the top.


Given the nature of the TreSound1's design and construction, disassembly is highly discouraged. I was also not confident of taking this apart in a non-destructive manner and thus relied on the manufacturer's own photos and spec sheet to know more about the assembly process and the speaker units inside. The shell itself is made of high-density wood from the Nordic mountains that was vetted to function as an acoustic chamber here. The wood is shaped by hand and lathe before getting four coats of the piano paint in the four colors on offer. It then undergoes 13 polishing cycles before the individual pieces are hand assembled and further finished to make for a true premium product. The conical shape thus provides homage to the source of the wood while also enabling sufficient room for the 3-way speaker crossover used inside to emulate a 2.1 speaker setup. The lows are handled by a relatively massive (for the size of the speaker) 5.25" subwoofer inside the wooden cabinet at the bottom. TRETTITRE says its engineers thickened and widened the foam surround to match that of a 6.5" speaker and the diaphragm itself is a 2-layer compound paper cone to where the combination results in a bass extension as low as 38 Hz!

The mids are catered to by two 2.25" full-range dual neodymium magnet speakers exclusively to allow low distortion across the board with "special emphasis on vocals and a more transparent reproduction" of music. These are supported by two 1.25" 25-core silk film neodymium magnet tweeters in a manner that does seem akin to higher-end car stereo systems. The tweeters are present behind the steel grills along with the full-range speakers firing outwards to make for the surround sound experience. The goal is that the sound signature from the TreSound1 will be the same no matter where you are around the speaker. The tweeters help extend the rated frequency response all the way up to 20 kHz too. The blown-up render above shows an electronic crossover system as well as a Bluetooth SoC along with heatsinks for the integrated Class D amplifier taking in the power and feeding it to the speakers in a 2 x 15 W + 1 x 30 W configuration which leads me to believe the sub-woofer takes up the 30 W portion and the set of tweeters as well as the set of full-range speakers take 15 W each.
