Commentary
A speaker system developed for export to Europe, mainly Germany.
The system planning and sound quality coordination were done by Onkyo Germany (Onkyo Deutschland GmbH Electronics) staff, and the basic design and manufacturing were done by Onkyo technical staff.
A 21 cm cone type unit is used for the low range, and a 12 cm cone type unit is used for the middle range.
The material of the cone type vibration plate is made from Finnish pulp made from Northern European conifer as the main raw material, and is tuned with an emphasis on the reproducibility of acoustic instruments.
A 2.5 cm soft dome type tweeter is used for the high range.
The vibration plate is made of chemical fiber and has a flat characteristic with few peaks and dips that cause stimulating sound quality.
The enclosure uses high-density particleboard and is assembled with a unique joint structure using real-wood angle block on the left and right sides of the top plate.
In addition, in order to maintain visual harmony with other furnitures, etc., a wood grain nut board is used, and in addition, the level difference at the boundary between sub RUNNET and baffle is completely removed for a smooth finish.
