SeaWave original technology

The world's first true and authentic horn type speakers






First real rounded wood horn
with Compression Driver


The horn in cone shape made of woods using compression drivers. Only this can be called the real horn.
Welcome to the world of the first real horn that have never been made!








First molded aluminum
Woofer enclosure not assembled


The enclosure of Plotinus is made of all-in-one casting that does not require assembling because there is no seam. All-in-one casting is very hard to make, and costs a lot more. But the manufacturing cost is not important, because Plotinus is made only for quality of sound. The enclosure of Plotinus made for quality of sound is finished as a beautiful product like a work of art after being made in all-in-one casting and processed with CNC several times.
Aluminum bars are used for strengthening the structure of enclosure, and for anti-resonance. In addition, anti-vibration fluid was applied three times to the inside of the enclosure to suppress additional internal resonance.
Seawave makes the enclosure of Plotunus by applying all its technologies and efforts to every part of it however small they may be.






First Korean traditional paper com-

pression driver membrane


The Tweeter of Plotinus is special. The Twitter made of Korean paper is light and soft. The Korean paper Tweeter, which was applied to Plotinus for the first time in the world, makes high range sounds very naturally without any sharp sound.








Non soldering technology


Every connecting point is twisted and pressed instead of applying soldering. NST is a small effort to make the premium high-end speaker, using the technologies recognized for the quality of sounds in Seawave’s previous products.



Incredible Inductor


First incredibly low resistance Inductor invented and used by SeaWave original technology. The proprietary inductor uses an 11-gauge (6N) 99.9999% purity copper foil to reduce the internal resistance to 1/10 than usual inductor.  It mean just like no use inductor in ordinary concept.
