Atom Acoustic Engine — Tweeter (Pair)

Compact High-Frequency Horn Engine

Designed to work with your existing speakers — this is not a standalone speaker.

Focused Air. Precise Detail. Compact Control

The Atom Acoustic Engine is a compact horn-based high-frequency system designed to take control of the upper range where detail, air, and spatial cues live.

Operating from approximately ~2.5 kHz to 20 kHz, it replaces conventional tweeters with a high-efficiency compression driver and precision horn.

Fully passive. Fully analog. Fully adjustable.

How It Works

The Atom sits between your amplifier and speaker.

It takes control of the upper frequencies…

while your speaker continues handling the body of the sound.

No internal modification required.

The Acoustic Engine

A compression driver…

coupled to a precision horn…

delivers speed, clarity, and controlled dispersion.

Operating from ~2.5 kHz upward, it handles the region where shimmer, air, and spatial detail define the listening experience.

Continuum Tuning Array

The Continuum Tuning Array lets you shape both crossover engagement and horn level…

so the system works with your speaker and your room — not against it.

Continuum Capacitor Array

Three selectable crossover profiles:

• Prominent — more forward presence

• Neutral — balanced

• Relaxed — smoother presentation

Dial it in… then refine further if desired.

Continuum Resistor Array

Adjust the horn level to match your system:

• Bold — increased presence

• Neutral — balanced output

• Relaxed — softer presentation

Simple control. Proper integration.

Integration

• Horn aligned flush with front speaker baffle

• External crossover and tuning access

• No cabinet modification required

Connections

Amplifier → Atom → Speaker

The full 2-way crossover is built into the plinth.
