HORN X2 MAGNUM
Large-Format Unified Compression Platform
900 Hz – 20 kHz
The Horn X2 Magnum is a large-format horn architecture engineered to replace the entire midrange and tweeter section of a conventional 3-way system.
Operating from approximately 900 Hz to 20 kHz, it uses a single high-efficiency compression driver and constant-directivity horn to handle the entire presence and high-frequency spectrum.
Fully passive. Fully analog. Fully adjustable.
This is not a tweeter module.
It is the upper system.
Unified 900 Hz – 20 kHz Architecture
The Magnum crosses steeply at approximately 900 Hz using a 2nd-order electrical high-pass and integrated 2nd-order low-pass to the woofer.
From that point upward, one compression driver covers the entire vocal and treble band.
No midrange driver.
No mid-to-tweeter handoff.
No second crossover transition in the most sensitive region of hearing.
Most 3-way systems introduce two acoustic transitions between 900 Hz and 4 kHz. The Magnum eliminates one entire driver and one entire crossover node from that band.
Fewer acoustic sources.
Greater structural coherence.
Why 900 Hz Matters
Large 12"–15" woofers begin narrowing dispersion and accumulating energy above 1 kHz. When forced to reproduce upper-mid content, congestion and instability can occur at realistic listening levels.
Crossing at 900 Hz removes that region from the large cone entirely and assigns it to a 112 dB compression driver operating with substantial acoustic leverage.
Because very little electrical input is required for high output, thermal compression is minimized within normal listening ranges. The result is preserved dynamics and composure at scale — even with low-power amplification.
System Efficiency Continuity
With 112 dB sensitivity on the TD-460/N platform, the Magnum pairs naturally with high-efficiency 12"–15" woofers to create a truly high-sensitivity two-way system.
There is no efficiency bottleneck in the upper band.
No need to pad down output to accommodate a low-sensitivity tweeter.
When combined with a properly chosen woofer, the result is a coherent high-efficiency architecture from bass through 20 kHz — particularly well suited for low-power amplification seeking dynamic ease and headroom.
TD-460/N Constant Directivity Horn
2" throat (49 mm)
60° horizontal × 40° vertical coverage
Uniform directivity across its operating range
Rigid polyurethane construction
The horn mouth incorporates dual flares designed to reduce internal reflections and axial cancellation. By minimizing path-length differences near the throat, high-frequency propagation remains uniform and controlled.
This geometry supports stable extension to 20 kHz while maintaining controlled dispersion beginning in the presence region.
CP750Nd Compression Driver
3" (72.4 mm) voice coil
Titanium diaphragm
Polyester surround to suppress ringing
Neodymium motor assembly
112 dB sensitivity (1W / 1m on TD-460/N)
8 Ω nominal impedance
60–80 W AES / up to 160 W program power
From 900 Hz to 20 kHz, a single diaphragm handles the entire mid/high spectrum.
No mid driver. No separate tweeter.
Adjustable Analog Integration
Sensitivity is adjustable via plug-in resistor sets.
Crossover engagement is adjustable via plug-in capacitor values.
Each pair is delivered pre-configured for your intended woofer and tonal balance, with analog refinement available for room integration.
No DSP.
No software.
No hidden processing.
Pure passive architecture.
No Internal Crossover Required
The complete two-way crossover is built into the external plinth.
There is no need to design or mount a mid/high network inside your cabinet. No need to remove the woofer to access a crossover panel.
All tuning components are accessible from the top plate.
Capacitor and resistor changes can be made in minutes — now or years from now — without opening the enclosure.
Less complexity. Full analog control. Immediate access.
Architectural Efficiency
A serious large-format 3-way system requires a midrange driver, a tweeter, additional crossover sections, and more cabinet complexity.
In high-quality builds, this often adds $1,000–$2,000 in additional components and integration work in 3 way syatems along with an extra acoustic transition in the vocal band.
The Horn X2 Magnum replaces that entire mid/high structure with a unified 900 Hz–20 kHz compression platform.
One driver.
One horn.
One crossover transition.
The investment is not for more parts.
It is for fewer, more capable parts operating with greater acoustic leverage.

A Serious Investment
Four thousand dollars is not casual.
The Horn X2 Magnum replaces the entire midrange and tweeter architecture of a large-format system with a unified, controlled acoustic platform designed for structural coherence, preserved dynamics, and long-term serviceability.
If that architecture aligns with your system goals, the value becomes rational.
