Proprietary Technology
We don’t just assemble speakers; we engineer sound. Discover the patented acoustic technologies that set Sandy Audio apart.
Proprietary Neodymium Transducers
Our in-house developed neodymium low-frequency drivers utilize a unique cooling geometry. By optimizing the magnetic flux density, we achieve unprecedented SPL output while reducing thermal power compression by over 30%.
- Ultra-low distortion at high SPL
- Advanced voice coil cooling
- Lightweight aerospace materials
- Extended driver lifespan
Phase-Linear FIR DSP Filtering
Unlike traditional IIR filters that cause phase shifts, our high-resolution 96kHz/24bit DSP engine employs custom FIR (Finite Impulse Response) algorithms. This guarantees absolute phase linearity across the entire frequency spectrum.
- Zero phase distortion
- Precise crossover points
- Optimized transient response
- Dante network integration
3D-Simulated Polymer Waveguides
Using advanced fluid dynamics software, we design high-frequency waveguides that ensure perfect cylindrical wave propagation. This eliminates comb filtering in our line arrays, delivering crystal-clear highs to the back row of any stadium.
- Uniform horizontal coverage
- Elimination of comb filtering
- Resonance-free polymer body
- Seamless array coupling
