SeaWave Acoustics Master ultimate horn system

The SeaWave Acoustics Master ultimate reference horn system has been developed by an expert with over 30 years of experience in loudspeaker design with the greatest care to the smallest detail.

1000mm horn speaker finished with pure lacquering


The 1000mm sized ultra large horn is made by the maker after processing the raw lumber over 6 months. The coating, the life of the horn, is pure lacquering with 16 times of coats applied that was entrusted to a Japanese professional. 

Enclosure consisted of 40mm white birch plywood

The enclosure for Super Woofer and Woofer are subject to lots of vibration, which affects the quality of sound negatively. To suppress the vibration, the enclosure is made of 40mm white birch plywood in solid matrix structure and the weight of the connection part (horn base) to connect the horn reaches almost 120kg, so not only its structure, but also its overwhelming weight minimize the vibration generated from the enclosure. 

Bronze casting stand reaching 120kg


The connection part that connects the horn and the base is made of bronze to prevent vibration. Its weight reaching almost 120kg ensures its solidity.

1000mm sized horn completed by the design of a specialist

It’s very hard to make the horn in regular shape, and that in ultra large size reaching 1000mm through processing of raw lumber. The horn made by the maker through 6 month’s hard work per horn is a piece of work without a precedent. 

Commitment to the suppression of vibration

The weight reaching 350kg for one of a pair is an effort to suppress the vibration by using 40mm sized white birch enclosure, 120kg weighted bronze casting base, etc.

HDMT(High Damping Metal technology) insulator

For the insulator that removes the ultra wide band vibration that ranges from 0.1Hz to  10MHz, High damping metal, a special materials used in particle accelerators etc, is being used.
