Commentary
This 3-way speaker system uses a flat woofer.
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.
There is a variety of exterior finishes, IB1S has a black texture finish and IB1-AW has a walnut finish.
