Discover Eighteen Sound technologies for distortion control and improved transient response: SDR, DDR, AIC, ACS, TPM, and proprietary phase plug 3P.
SDR – Single Demodulating Ring
The Single Demodulating Ring (SDR) employs an aluminum ring embedded in the magnetic structure to reduce intermodulation distortion and improve transient response.
DDR – Double Demodulating Rings
The Double Demodulating Rings (DDR) use two aluminum rings inserted in the pole piece to minimize intermodulation and harmonic distortion while enhancing transient performance.
ACS - Active Cooling System
The Active Cooling System (ACS) covers multiple methods to extract heat from the transducer, reducing power compression and increasing power handling capability.
AIC - Active Impedance Control
The Active Impedance Control (AIC) technology uses a secondary stationary coil placed on the pole piece. The magnetic field generated by this coil linearizes impedance, increases sensitivity, extends the high-frequency range, and reduces both harmonic and intermodulation distortion.
TPM - True Piston Motion
The True Piston Motion (TPM) concept enhances high-frequency behavior of high-end compression drivers. It uses a proprietary Titanium Nitride coating process combined with pure Beryllium diaphragms, increasing stiffness without adding mass. TPM doubles material stiffness while maintaining predictable frequency roll-off and preventing unwanted resonances at high frequencies.
3P - Proprietary Phase Plug
The Proprietary Phase Plug (3P) combines radial and tangerine slot designs. Short slot lengths and high flare coefficients ensure low distortion in mid-high frequencies and provide a smooth wavefront at the horn entrance.
