General : Unique compact monitor, made in South Korea by Bo San and his team, a practicing Buddhist Monk.

Technology : We know many of the speakers in the world well. Usually the technology is broadly the same everywhere. A 2-way or 3-way speaker, and a large bass woofer and a smaller midrange driver and a tweeter, housed in a usually MDF/HDF enclosure. They all sound great, the more expensive ones often better than the cheaper ones because of the better components. Most components come from some factory. Units, crossovers, cabinets and you name it. Seawave Acoustic is different. The brand caught our attention during the Hifi Deluxe show at the Marriott Hotel in Munich in 2022, and this was the room where we stayed the longest. In the room, the AM23 from Seawave Acoustic was playing. The sound was wonderfully beautiful, musical and just very real, very addictive. We decided fairly quickly to bring this brand to the BeNeLux for music lovers here. Truly everything is different about Seawave Acoustic.

First of all the special enclosure. This enclosure is a solid cast enclosure of AC4C aluminium. Not standard aluminium but Aluminium combined with Silicon and Magnesium. This provides a very rigid, heavy but also resonance-free enclosure. Of course, it is a complex and expensive undertaking to produce such an enclosure, but the result is truly excellent. It not only looks stunning, but also sounds extremely good. In the enclosure there are 3 units. A Basswoofer from Eton, custom produced for Seawave Acoustic. From 1.2KHz the titanium compression driver in the horn is used, up to about 17KHz, so the entire midrange comes from this unit without phase jumps. It is a small horn turned from a solid wood laminate block. On top of the AM23 sits a Beryllium supertweeter that handles the ultra high range up to 35,000 Hz, this Beryllium supertweeter radiates upward for extra spaciousness.

The cabinet and the units are already very special. But the crossover technology is the next thing in which Seawave Acoustic excels. Seawave Acoustic makes everything themselves. The resistors, the Coils (Inductors) and the Capacitors. A normal inductor is a coil of an enormous length of thin copper wire. A coil with the same value is made by Seawave Acoustic from only 9 meters of flat copper wire. As a result, the signal path is considerably shorter than in speakers with traditional inductors, and you hear that directly. Ultimately, all these ultra-high-quality components are connected together via NSC, which stands for Non Soldering Connection. No trace of solder is used in the entire Seawave AM23. All components are crimped together under high pressure. Even the Litz wires of the units themselves are crimped directly to the internal wiring. We have never seen or heard anything like this. The reason for NSC is that Seawave Acoustic believes that soldering slows down and distorts the current, so dynamics are lost. By using NSC, the dynamics are preserved and the speakers sound much more open. Finally, the included stands are also made of solid Aluminium, with blunt plastic spikes on the underside, and carbide spikes and couplings between the enclosure and the stands. Technically, the Seawave Acoustic AM23 is therefore a technical masterpiece, and we dare to claim that the Seawave AM23 is among the most advanced monitor speakers on the planet. But good technology is nice, but does it sound good?

Sound : Setting up the AM23 is quite difficult. The stands are heavy, and the speakers weigh more than 30kg, and placing them on the 3 metal blocks without being able to see it well is quite difficult. Ohm-Audio BV will help you with that. But once placed and positioned correctly, an enormously musical soundstage reveals itself that is very spatial, precise and refined. The bass goes very deep and is very potent, and sounds very precise. Even at high volumes, the control is phenomenal. The transition to the mid/high horn is inaudible. The bass range, midrange and high range play very harmoniously together, which provides an intriguing listening experience. It certainly takes 200 hours to get the mid horn properly broken in, but then you have something special. A musical stage unfolds that we have not heard before from a monitor of this size. A large 3D bubble, a very good dynamic reproduction and the AM23 sounds super transparent, but, and that is remarkable, it sounds full and round at the same time. Also remarkable is that, despite the fact that the midrange driver is in a horn, you have no horn coloration and the sound does not sound like a typical horn speaker. The Seawave AM23 is a truly musical speaker, which can hit hard when it needs to, but remains very controlled in the meantime. But the Seawave AM23 can also play at quiet room volume and then you can still enjoy the entire recording in a refined and musical way.
