The Horn X2 – The Smarter, Faster Way to Build a Real Speaker  

Note: The Horn X2 is the updated name for our Horn 2 PLUS 2 system — same  components, same performance, just a new name to reflect its evolution.

The Horn X2 is a complete horn-loaded high-frequency system with an integrated 2-way crossover, designed to take over your speaker's treble and upper midrange — cleanly, confidently, and without the usual DIY headaches.

  • No soldering.
  • No cabinet mods.
  • No crossover guesswork.

Just place it on top and plug it in.

How It Works

The Horn X2 connects directly to your amp and takes over everything above ~2kHz using its built-in high-pass and low-pass filters. It completely replaces your tweeter (yes, even if your speaker already has one), delivering clarity, control, and dynamic energy that traditional tweeters can’t match.

Already have a tweeter?
We electronically “decapitate” it at 2kHz and take over — simple as that.

What You’re Getting

  • Precision aluminum horn (B&C ME45)
  • Beyma CD171 FE/PK compression driver with ketone polymer diaphragm
  • Hand-oiled 3/4" American walnut plinth (other woods available)
  • 6061 aluminum horn mounting plate
  • Integrated crossover with Mundorf EVO OIL caps, Jantzen inductors, Solen or Auricap XO options
  • Adjustable L-pad for matching sensitivity to your woofer

It’s All Included:

  • High-pass filter (1st-order) and low-pass filter (2nd-order) built in
  • No external crossover needed
  • Infinitely variable attenuation (108 dB down to 85 dB)
  • Crossover frequency adjustable via resistor/cap changes (you can request specific values or ask for help)

🔌 How to Use It

  1. Set the Horn X2 on top of your existing speaker or DIY cabinet
  2. Connect your amp to the center terminals on the rear
  3. Connect the outer terminals to your woofer

That’s it — you're done. No need to modify your speaker’s internal crossover. The Horn X2 takes over cleanly and gives you a seamless, high-performance horn system in minutes.

Start from Scratch? Easy.

Got a woofer and a box? Great.
The Horn X2 does the rest. Build your own speaker without ever touching a crossover schematic. You’ll have a full-range, high-performance horn system in minutes — not months.
