Полочная акустика — Shinjitsu Audio Hiro Junior

The Hiro Junior is a horn-loaded stand-mount loudspeaker from Shinjitsu Audio, sold as a pair. It scales the Hiro design down to a 28-liter internal volume for mid-sized listening spaces while keeping the same horn used in the brand's larger models.

Key specs that matter

The top end is loaded by a B&C ME45 horn, an exponential design with a 1-inch throat and 90 x 40 degree nominal coverage. Rated response runs from 37 Hz to 20 kHz within 3 dB, and amplifier power of 6 to 80 W is recommended. Each cabinet measures 63.5 x 22.8 x 34.2 cm and weighs 12.7 kg.

Engineering and use context

Each enclosure is CNC-cut from 3/4-inch Baltic Birch with rabbet-joint construction for internal rigidity. A top-mounted resistor socket lets the owner adjust the high-frequency level of the horn relative to the rest of the system.

Pairing

The 6 W lower bound means the Hiro Junior can be driven by low-output amplifiers, while its 80 W ceiling also admits stronger amplifiers.
