Horn X2 — Mid to High-Frequency Horn Engine

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

Focused Extension. Effortless Detail. Built to Modern Standards

The Horn X2 is a compact horn-based acoustic engine designed to take control of the most critical part of your system — the midrange and high frequencies.

Operating from approximately ~1.5 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 Horn X2 sits between your amplifier and speaker.

It takes control of the mid to upper range…

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 ~1.5 kHz upward, the horn removes strain from your main driver and stabilizes the most sensitive region of hearing.

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.

Capacitor Array

Three selectable crossover profiles:

• Prominent — forward midrange
• Neutral — balanced
• Relaxed — smoother presentation

Resistor Array

Adjust horn level:

• Bold — increased presence
• Neutral — balanced output
• Relaxed — softer presentation

Integration

• Horn mouth flush with front baffle
• External tuning access
• No cabinet disassembly
• The supplied resistor array covers the overwhelming majority of systems and listener preferences. Because every room, amplifier, and loudspeaker behaves differently, some advanced users may choose to explore additional resistor values beyond the supplied tuning set. Compatible non-inductive resistors are inexpensive and readily available from common speaker parts suppliers such as Parts Express, Madisound, Solen and Amazon.

Connections

Amplifier → Horn X2 → Speaker

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

Real-World Performance

• Horn-loaded high-frequency system
• Improved clarity and vocal presence
• Reduced strain on the main driver
• Greater separation and control

Crossover response: the graph below reflects the Horn X2 on our test rig Horn X2 paired with the Mark Audio CHR 120 with a 1 ohm resistor. The sensitivity of your product will vary depending on your resistor settings.

~1.5-to 1.6 kHz out to 20 kHz depending on capacitor value.
