Seas System Designs are developed to give everyone the possibility to listen to our drivers in a complete loudspeaker system. In addition to a detailed description of complete systems, we also present crossovers and sketches to boost your own design ideas. Besides using well-known designers like Joseph d’Appolito and Murray Zeligman, our Seas R&D team spends hours listening - not only to our products, but to finished systems they design themselves. All of this experience and knowledge we are pleased to share with you through this section of the website.

As a part of our quest for a breathtaking sound, we have cooperated with Siegfried Linkwitz for several years. His designs are unique and challenge our ideas about what a speaker should look like in order to reproduce sounds naturally in a room. The resulting designs can be found at
