Galeforce Power/Crossover Guide
Galeforce Audio Recommended Speaker Crossover & Power Guide
Proper crossover settings are critical to getting the best combination of output, sound quality, and reliability from your speakers.
The recommendations below are intended as practical starting points for Galeforce Audio dealers, installers, competitors, and customers. As power increases, the recommended high-pass crossover generally increases to help control cone excursion and protect the speaker.
All power ratings shown are per speaker.

Understanding the Chart
Daily / Recommended
These settings are intended to provide a strong balance between frequency response, output, sound quality, and long-term reliability. For most systems, we recommend starting here.
High Output
For customers applying additional clean power and looking for more overall output, raising the high-pass crossover helps reduce unnecessary low-frequency excursion while allowing the speaker to play louder within its intended operating range.
Competition / Advanced
These settings are intended for experienced installers and competitors who understand gain structure, clipping, EQ, crossover implementation, and the mechanical limitations of the speaker.
The competition-level wattages shown above are not continuous RMS power-handling ratings or blanket recommendations for everyday use. They represent power levels that may be used in properly tuned high-output or competition systems.
Clean power and proper tuning are required.
Important Crossover Notes
These recommendations should be treated as starting points rather than absolute limits.
Actual safe crossover points can vary depending on:
-
Installation and speaker loading
-
Enclosure or pod design
-
Amplifier power
-
DSP and crossover implementation
-
Crossover slope
-
EQ and frequency boost
-
Gain structure
-
Clipping
-
Program material
-
Duration of high-output use
A speaker receiving significantly more power should generally be crossed higher than the same speaker operating at lower power.
Crossover Slope Matters
The frequencies in this guide assume a 24 dB/octave crossover slope.
A 100 Hz HPF at 24 dB/octave does not provide the same protection as a 100 Hz HPF at 12 dB/octave. Shallower crossover slopes allow substantially more energy below the selected crossover frequency to reach the speaker.
When using shallower slopes, additional caution should be taken and a higher crossover frequency may be appropriate.
A Note About High-Power Systems
More amplifier power does not automatically mean more usable output.
Once a speaker reaches its mechanical or thermal limits, additional power can create distortion, excessive excursion, or heat rather than additional clean output. Proper crossover selection allows high-output systems to concentrate amplifier power within the frequency range where the speaker can use it most effectively.
For competition systems, watch the speaker, listen to the speaker, and understand what your DSP and amplifier are actually doing.
When in doubt, start with the higher recommended crossover point and work downward carefully.
