At the beginning of the process, each chassis is individually measured. Based on its characteristics the phase is corrected in particular for being in-phase at transition frequency. Next, each chassis’ magnitude response is linearized and gain variations are corrected. A six-channel linear-phase digital crossover is generated. All corrections are convolved into the crossover, individually for each driver. The resulting total performance combines into an almost perfect speaker. Taken to the Klippel measurement system, all system parameters have been validated and partly refined, optimizing radiation pattern and minimizing distortion.

Measurement of the entire speaker (installed in the room) allows to derive the necessary room corrections. Sonic degradations of room modes (magnitude and phase) are reduced within useful acoustic boundaries without over-correction. Additionally, mid and high-frequency performance improves delivering a balanced and holographic soundstage. The digital processing is performed with non-compromise 64bit floating point accuracy throughout the entire processing chain. The FIR filters employed work with 64-128k filter tabs (maximum 524k), giving unprecedented low frequency resolution and correction possibilities.
