"When Peter Thomas developed the twenty series he set out to make every part of the speaker (except the actual drive units) as inert as possible, the cabinet, the driver chassis and the crossover construction were all looked at with a view to minimising vibration. He used sensors on individual parts and looked at waterfall plots of the signal decay in order to identify what was coming out of the speaker after the signal had stopped. The perfect speaker would stop emitting sound immediately but in reality they don’t, they continue to resonate for many milliseconds afterwards. It is these delayed resonances that are the enemy of speed and detail and it was Peter’s design goal to minimize such artifacts so that it was possible to then hear the benefits of the drive units and components in the crossover..."
