Testing the new Finisterrre

Today Al was in the workshop testing the audio and frequency response for the new Finisterre speakers and adapting them accordingly. A Swiss watch-maker’s attention to detail is required!

Resonance and Cabinet Design: The enclosure or cabinet in which the speakers are housed can have resonances at specific frequencies. These resonances can cause dips or peaks in the frequency response. We need to ensure a proper cabinet design, including bracing and damping materials. Al played around with the damping.

Speaker Driver Characteristics: The characteristics of the speaker drivers themselves can impact the frequency response. The Thiele-Small parameters, including the resonant frequency (Fs) and the Q factor (Qts), play a role in how the speaker performs at different frequencies. We’ve used the very best Purifi speakers for the main drivers.

Crossover Design: If your speakers are multi-driver systems with crossovers, the crossover design and component selection can affect the frequency response. Al is continuing to test the crossover designs with support of electrical engineers.

Room Acoustics: The environment in which the speakers are tested or used can greatly affect the perceived frequency response. Standing waves, room resonances, and reflections can cause certain frequencies to be attenuated or boosted, leading to dips or peaks in the response. We’re testing in different environments.

Measurement Artifacts: The measurement equipment used to assess the frequency response can introduce artifacts. For example, the microphone’s placement, calibration, and the measurement software can all impact the measured response. A next step is to try with various equipment.
