DOPPELHORN 10.1

Our debut speaker is inspired by early innovators and global sound system culture. It features a powerful 10‑inch paper cone woofer in a moderately horn loaded bass reflex cabinet, passively crossed over to a 1‑inch compression driver on a custom developed external horn.

This versatile full-range system delivers clear highs, natural mids, and a tight low end with generous headroom. It was created to suit your home hi-fi setup just as well as design-conscious venues looking for a powerful compact setup. To us, it embodies the ideal hybrid – the best of both worlds from hi-fi and PA.

The waitlist is now closed and regular preorders will open soon – we will notify you about further steps. Please don't hesitate to ask about special requests, non-EU shipping, or B2B inquiries. Images and specs are of a pre-production model – slight variations are to be expected.

Design Details

Our high frequency horn is a specially developed part, produced in-house from industrial grade 3D filament. Its design draws from Le Cléac'h's work on wave propagation, with a calculated expansion that enables natural, smooth reproduction and controlled directivity. The horn also improves soundstage precision by reducing chaotic reflections in your listening space.

The striking frontal horn moderately loads the woofer in the low midrange and upwards, increasing its efficiency and reducing strain, ultimately lowering distortion. We use bass reflex ports to increase low-end output: The air in these openings resonates with the driver and enables sub-bass extension down to 37 hertz. We use state of the art additive manufacturing to make this part in-house as a single component, including integrated cabinet bracing.

To ensure that all components are playing together harmoniously, we spent a long time refining the speaker's internal passive crossover: A hand-soldered circuit made from high quality European parts. Its careful tailoring to the speaker's behavior helps to ensure clear reproduction with low distortion.

On speaker's back panel, you will find a metal plate with four binding posts: Two as inputs and the other two for connecting the external driver. Since DOPPELHORN is passive, the only thing you need to plug in here is your amplifier, delivering both power and the signal. We included an attenuator for the high frequencies, since we're leaving it up to you to dial in the tweeter's strength depending on taste and use case.

All four side walls are fitted with standard threaded flanges accepting M20 bolts. One holds the external horn in place, while the remaining three enable integration of other attachments like stands or brackets. With these flanges, the speakers become modular, opening up the choice of vertical or horizontal use and other diverse configurations.

Material Philosophy

We are relying on functional design and honest materials: Baltic birch plywood and industrial polymer, combined with stainless steel parts from local partners.

Right to Repair

DOPPELHORN is designed to be airtight, but also accessible. We are actively working on a repair guide for you to use in case components should wear out during the speaker's long life.

Handmade in Berlin

We are a two-man team that formed during our industrial design studies in Potsdam. Our studio in Berlin is home to almost all production steps: Design, parts manufacturing, and assembly.
