Commentary

A large 4-way studio monitor speaker system.

Two 38 cm cone Woofers 2231A are installed in the low range, and 30 cm cone Woofer 2202A is installed in the middle and low range.

The mid-range range is equipped with a horn type mid-range combining an acoustic lens 2308, an exponential horn 2311 and a driver 2440.

A horn type tweeter 2405 is installed in the high frequency range.

The network section uses a 2-channel multi-amp drive system with a crossover frequency of 250 Hz. Therefore, an optional channel divider 5234 and filter boards 52 to 5121 (two boards when using stereo) are required for connection. Frequencies above 250 Hz are divided by the built-in network.
In addition, the horn type tweeter for high frequencies can be adjusted with the volume type attenuator on the front panel.

The tweeter and horn driver can be switched between left and right to obtain the optimum sound source position.

It can also be hung upside down with the iron reinforcement fittings.

There are 2 types of external variations, 4350A uses gray finish and black grill, 4350 WXA uses walnut finish and blue grill.
