The performance of speaker unit is deep and full in low frequency, beautiful and lyrical in the midrange, clear and bright and elegant in the treble, and full of penetration, also its vocal performance is very outstanding. It is a good match with the tube amplifier, such as 300B, 2A3, EL34, KT88, etc.; Because the speaker unit’ sensitivity is high, the output power of 3 to 5W can produce very good sound. At the same time, it is also suitable for transistor power amplifiers.
