Horn X2 PRO Upgrade Service
Bring your existing Horn 2, Horn 2 PLUS 2, or Horn X2 up to full PRO specification — without buying new.
Send us your current unit and we’ll retrofit it with the latest symmetrical crossover and inert cradle mount. The same precision electronics, damping, and tuning found in every Horn X2 PRO build — applied directly to your existing system. You keep the original horn body, driver, and key components. We handle the rest.
What’s Included
Each upgrade replaces the internal network and mechanical base with the full PRO specification. Your horn is refitted, retuned, and tested before return shipping. The result is smoother phase alignment, improved integration, and a more stable foundation.
Included in the upgrade:
• Symmetrical 2nd-order high-pass / low-pass crossover at ~1650 Hz, adjustable via capacitor (reuse your existing capacitor) • Adjustable horn output and selectable voicing through capacitor tuning (Chebyshev-like, Butterworth, Bessel-like, or hybrid) • Inert PLA cradle mount system with internal damping • Full retuning and measurement verification before shipment
You retain your horn body, driver, and resistors — we supply the PRO crossover assembly and cradle base.
How It Works
1. Place your order for the Horn X2 PRO Upgrade Service. 2. We email you detailed packing and shipping instructions. 3. Send us your Horn 2, Horn 2 PLUS 2, or Horn X2. 4. We retrofit it to full PRO specification and return it ready to play — usually within two weeks.
Service includes a $300 upgrade fee and $49 flat domestic return shipping. International clients, please contact us for rates.
Frequently Asked Questions
What models qualify?

Approximately two weeks from the day we receive your unit until it ships back to you.
Can I request a new wood finish?
Yes. Wood plinth swaps are available at additional cost. Current hardwood options include Walnut, Oak, Black Limba, Padauk, Wenge, and Morado — please contact us for availability.
