The WX-LP100 from Panasonic is not an ordinary speaker. It is specially built for use in the schools or events that require a wireless speaker. Priced at 125,000 Yen or approx. less than €1000, the speaker features microphones that use infrared technology, and offers a maximum output of 10W at 4Ω and works on frequencies of 100Hz to 15KHz.
