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 speaker 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 powerful but compact sound. To us, it embodies an ideal hybrid – the best of both worlds from high fidelity and pro audio.

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.

Design Details

Our high frequency horn is a specially developed part, produced in-house from industrial grade 3D filament. Its design draws from J.-M. Le Cléac'h's work on wave propagation, with a calculated expansion that enables natural, smooth reproduction and controlled directivity. The horn also helps to improve 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 make use of bass reflex ports to increase low-end output: The air in these openings resonates with the woofer and enables sub-bass extension down to 38 hertz. Thanks to advancements in additive manufacturing, we can make this part in-house as a single component, including integrated cabinet bracing for reduced resonances.

To ensure that all components are playing together harmoniously, we spent a long time refining the speaker's internal passive crossover: We hand-solder this circuit from selected high quality European parts. Its careful tailoring to the speaker's behavior helps to ensure smooth reproduction with clarity and low distortion.

On the speaker's back panel, you will find a metal plate with four binding posts: Two as inputs and two for connecting the external high frequency driver. Since DOPPELHORN is passive, the only thing you need to plug in is your amplifier, delivering both power and the audio signal. We included an attenuator for the high frequencies, since we're leaving it up to you to dial in the top end signal 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 currently working on a care and repair guide for you 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. Our studio in Berlin is home to almost all production steps from design to manufacturing and assembly.
