Commentary
By thoroughly analyzing the sound of small speakers and acquiring the know-how to create a free-flowing sound, this speaker system has improved the low-frequency reproduction capability and efficiency that are the destiny of small speakers.
High Crystal Delta Olefin 14 cm cone woofer is used for the low range.
By shaping the cone into a unique S-curve shape, fhFrequency characteristics are obtained without disturbance of characteristics due to resonance vibration of peak and edge of (high resonance frequency).
In addition, it uses a 30 φ mm voice coil with the same diameter as the D-500, and realizes high efficiency even though it is a small-diameter unit with strong driving force by double magnets of 80 φ x4 φ x12mm and 70 φ x32 φ x8mm.
A newly developed 2.5 cm soft dome type tweeter with titanium oxide coating is used for the high range.
By coating a polyester fiber base with a special material blended with titanium oxide, in addition to the high internal loss of the soft dome body, the high-frequency characteristics are improved.
In addition, the magnet is a double magnet with anti-magnetic design of 80 φ x40 φ x12mm and 70 φ x32 φ x10mm for cancellation.
