They have reinventend themselves several times.
They hit the audiophile world in the early 80's with their time window/frame series.. Went overreal big. I kinda lost track of t hem until the mid 90's when they were selling their popular priced "CX" series of transmission line series of speakers, aimed basicaly at the HT market. They were quite highly regarded by the press. I've got a pair of CX 21 bookshelves in my cellar/mancave/exercise room system and love 'em.
Then, they dumped the "CX" line for the garish "KX" line which, due to incredible sensitivity and booming upper/mid bass, atempted to challenge Cervin Vega for the college dorm/party speaker sweepstakes. I'd say they did quite well but they totally lost any respect in the audiophile circles. They were my party speaker of choice whenever anyone asked me.
Now, they seem to be entering the in-wall and HT system speaker market. I do recall a very flattering review of one of their HT(speaker)IB systems within the past two years or so.
Considering their propensity for hitting their target pretty much dead center, I'd say they are seriously worth considering.
