Commentary
This speaker system was developed by the reference series craftsman who challenged the limit of quality and cost performance.
The Coda7 features an inverted Woofer and Tweeter layout and a unique arrangement of bass reflex ports.
This decision was made based on the results of data verification after testing in all listening areas, and is advantageous in terms of sound quality, such as the sense of weight in the low range, the sense of speed in the high range, and the sense of overall balance.
A 13 cm cone type woofer is installed in the low range.
Pulp and corn paper is used for the diaphragm, and by applying a doping agent, excellent low-frequency reproduction beyond the range of small speakers is realized.
A 2.5 cm soft dome type tweeter is installed in the high range.
The baffle surface equalizes the mass by blowing the material into the mold with gas pressure. It is lightweight, highly rigid, and firmly secures the unit to eliminate external vibration and mutual interference of each unit.
The rear panel is molded by gas pressure in the same way as the front panel. Resonance is taken into consideration by equalizing the mass, and the design is loose even when high-quality cables are connected.
The connector RUNNET is attached to the edge of the woofer and the edge of the bass reflex port. The hole for the connector RUNNET in the baffle surface is eliminated. This prevents the effect of the hole on the frequency characteristics and improves the design of the baffle surface.
Speaker terminal compatible with banana plug is adopted.
