The Danish company introduced UNIT-4 Wireless+ portable studio speakers with a proprietary W+ Link wireless interface. Power comes from a built-in battery, the charge of which is enough for 20 hours of operation. Two-way speakers, which are positioned as reference monitors, are sold in Europe for €800 per pair.
Each loudspeaker weighs 2.5 kg, volume 3 liters. Drivers: 1″ silk tweeter and 4″ long-throw woofer with paper cone; crossover frequency – 3 kHz. Amplifiers – 2 x 30 W continuous power. Frequency response (+/-2 dB) – 50 Hz to 20 kHz.

In addition to the W+ Link wireless interface, there are also 3.5 mm analog inputs and 6.35 mm balanced TRS. To transmit the RF signal to the speakers (to both at the same time), a proprietary X02 transmitter is used, connected to the source via USB-C.
The speaker housing can be easily opened (you only need to remove 2 screws) to replace batteries, drivers or electronic modules.
