MartinLogan speakers undergo so many quality checks during assembly that nearly every speaker that enters through the performance testing room passes with flying colors. We still test each speaker before packaging.
After assembly, each speaker undergoes a battery of performance evaluations. Using precision-calibrated microphones and the latest, state-of-the-art computerized testing equipment, we plot phase, frequency-response, and impedance curves over the full audio band. The computer compares these results to those from the original reference speaker, approved on audition by the product's engineering team. This assures that the sound you hear is exactly as designed and intended.
