Thomson owns four of these brands: Acoustic Research, Advent, Jensen and RCA.

Acoustic Research and Advent were in fact inherited from Recoton, that went bankrupt in 1996. At that time, Recoton sold its loudspeakers and electronic division to Audiovox, and the accessories division (that includes headphones and wireless speakers) to Thomson. Thomson is also the parent company of RCA, that manufactures some wireless speakers models.

The wireless speaker technology is pretty new. Sony launched its first wireless speaker model three years ago, while the brands from Thomson marketed their products just about one year ago.

Speaking of wireless speaker brands, up to this moment they managed to cut some wires and keep a fair sound quality.

Acoustic Research AW871 speakers have been rated as the best performers by Jeff Bertloucci in his article Music on the Move, and at a nice price too, about $180 from online retailers.

RCA has the WSP150 wireless speakers that also sound good, not as good as AW871 though.

We already spoke about Advent's ADVW801 that was primarily made for outdoor use. Because of its splash guard, the 10-power per speaker is a bit damaged.

Unfortunately, no matter the brand name, all the FM based wireless speakers are susceptible to interference. The wireless speakers that work in the 900 frequency range will surely interfere with baby monitors and older models of cordless phones.
