|FAQ - Frequently Asked Questions|
What does SEAS mean?
Seas – Scandinavian Electro Acoustic Systems
Does SEAS produce speakers in Norway?
Yes. All drivers are assembled in a place called Rygge, close to the city of Moss in Norway, 60 km south of Oslo.
How long has SEAS existed?
T/S and the connection to the resonance frequency?
Qms, Qes and thus Qts are proportional with fo, and Vas is inversely proportional with fo squared.
In order to show what this means in practical terms to-day, we have measured fo in an L18RNX/P H1224-08 fresh from production.
Then we exercised the drive unit for 60 seconds with a 20 Hz sinewave at plus and minus 10mm cone amplitude, and measured again.
Why are the Waterfall plots gone?
We decided to remove the waterfall plot from the datasheets several years ago. The reason at that time was to allocate more space on the data sheet to other specifications.
All our drivers are carefully inspected and tested before they're shipped. We are using the comprehensive test equipment from Klippel in Germany. Both frequency response and impedance measurements are stored digitally at Seas.
