Made to order
The smallest speaker in the Estro range — but no less considered for it. A 4" coaxial driver delivers a point-source sound image in a compact cabinet small enough to live on a shelf, desk, or kitchen worktop. An onboard smart amplifier handles WiFi, Bluetooth, AirPlay, and Spotify Connect, so it connects to everything. Same Baltic birch plywood construction and wood veneer finish as the rest of the range.

Let’s get down to the details
Deep, detailed
sound
A compact coaxial smart speaker: single cabinet, single driver, and an onboard amplifier that handles WiFi, Bluetooth, AirPlay and Spotify Connect. Same Baltic birch plywood and wood veneer finish as the rest of the range.
Coaxial point-source driver
The woofer and tweeter share a single axis, producing a coherent, time-aligned image from a small enclosure.
Smart amp onboard
WiFi, Bluetooth 5.0, AirPlay 2, Spotify Connect and DLNA — no receiver or external hardware needed.
Compact form factor
190 × 160 × 160mm. Fits a desk, a shelf, or a kitchen worktop.
Passive internal crossover
The tweeter section is crossed over inside the coaxial unit itself, so there's no active crossover complexity.
Premium construction
12mm Baltic birch plywood, wood veneer, oiled finish — the same materials as the rest of the range.
In detail
The Cube,
up close.
190 mm tall and 160 mm across, so it fits where a proper speaker normally can't — a kitchen shelf, a desk, the console by the front door. The cabinet is built the same way as the big ones, just less of it.

N° 02 · The cabinet
Baltic birch.
Our master carpenter uses baltic birch plywood to construct each box. It’s really important to us that our speakers feel like high end furniture as well as be functional. Our design and manufacture process strives to use the same high quality joints, tight tolerances, and finishes that you’d expect from bespoke wooden furniture. The majority wood construction means they even smell like new wooden furniture when you first get them out of the box.
“I wanted to create a bad-ass looking, retro-inspired, wooden speaker that wouldn’t stick out in my living room. But also a speaker which sounded f*cking awesome”
— Dave H., founder

Couldn't find what you were after? Send a note. The workshop reads every email and replies within a working day.
Do I need an amplifier or a receiver?
No. The amplifier is inside the cabinet, and it does the streaming too — WiFi, Bluetooth 5.0, AirPlay 2, Spotify Connect and DLNA. Plug it into the wall and send it some music.
Can I buy just one?
What's a coaxial driver, and why does it matter?
How small is it, really?
Which woods can I have it in?
Is it made the same way as the bigger speakers?
