Четыре года назад в кратком обзоре беспроводных колонок ваш покорный слуга написал:

Теперь ждем активную беспроводную акустику профессионального (ау, Genelec!) и Hi-End-уровня.

Ожидание длилось около трёх лет. Именно столько времени понадобилось, чтобы серьёзные брэнды акустической индустрии смогли выпустить беспроводные колонки, обеспечивающие качество если не Hi-End, то уж точно Hi-Fi-уровня.
Все предыдущие были несерьёзными пукалками, в лучшем случае пригодными для озвучивания “тылов” домашнего кинотеатра.
Но к концу 2012 года специализированные журналы стали писать о беспроводной акустике как о восходящем тренде в Hi-Fi на ближайшие годы.

Wireless speakers become more and popular not only among computer and iPod users, but among home cinema and Hi-Fi fans too. After 25-watt Magnat Interior Wireless, I’ve found very similar speakers from professional acoustic systems developer – JBL, which is a unit of Harman International Industries, Inc.

JBL Control 2.4 G wireless speaker system

JBL CONTROL 2.4 G is 2-way, wireless active speaker system with 30 Watt nominal output power (total). Each speaker contains built-in digital amplifier, 0.50″ Titanium-Laminate driver for high frequency and 4″ compression-type driver for low. Their frequency response range is 50 – 20000 Hz (-3 dB), that is not bad for small boxes! The speakers have a magnetic shield and rubber shock pads on the top and bottom. JBL CONTROL look just like JBL’s Pro line of professional audio equipment. Complete set includes two speakers, 2.4 Ghz transmitter and remote control unit.
