Commentary

This 3-way speaker system uses center monitor specifications instead of IB1S.

It features a 25 cm flat carbon fiber woofer in the lower range and a 7.5 cm dome mid-range in the middle range.
The high-frequency range is equipped with a 2.7 cm dome type tweeter that employs a double chamber.

The network section uses a 24 dB slope to sharply divide each band.

The speaker terminal supports tri-wiring.

The enclosure uses a transmission line system to achieve excellent low-frequency reproduction.
In addition to using computer-controlled cut 25 mm and 18 mm MDF materials, the final assembly process is done manually, including the assembly of internal bulkheads and soundtracks.

The exterior is finished with black textured finish.
