A photo of the Rockport Technologies LYRA loudspeakers taken before they shipped out to their partners ReQuest Serious Play in Switzerland. “Every pair of Rockport Technologies loudspeakers is measured and listened to multiple times throughout the production process to ensure that Rockport Technologies reference frequency response curve for that model has been achieved to within .25dB. This is a time consuming method of loudspeaker production, but it is part of what makes a Rockport a Rockport.”
