Commentary
This is an R series speaker system that was available in ONKYO's low-cost lineup.
In order to finish at low cost, it has been devised in various aspects.
A 20 cm cone unit is used for the low range and a 12 cm cone unit is used for the middle range.
A dome-shaped unit with excellent directional characteristics is used for the high-frequency band.
The enclosure is not a sealed type, but a semi-bass-reflex type with only a circular opening and a structure to release the back pressure inside the enclosure. Thus, a response close to that of a sealed type is obtained.
The material is a first class chip board with a walnut finish.
The level control is mounted on the front baffle and can be changed in conjunction with the squaker and the tweeter.
In addition, it is equipped with a multi-amplifier terminal so that it can be used with 2 channels or 3 channels.
