Martin Chittum Jr (August 2000): RTR Electrostatic speakers are back!!! There is going to be one model. This comes with a special pair of AudioResearch OTL amps. It is sold as a package. Price has yet to be determined, probably less than $100,000. They are roughly 6 feet tall and 4 feet wide each. They will be distributed worldwide by Paul Heath Audio in Chicago. They have not been released yet. They should be available by the end of the summer. More info will be available in the coming months.
Jack E.Taylor (September 2000): I recall during the early 70's when Advent had the very popular Large Loudspeaker Model, it became very popular to disconnect the original Advent tweeter and connect an RTR Electrostatic tweeter to the Advents. The RTR ESL as I remember, was enclosed in a cabinet that was 12 X 12 X 6 inches deep as best as I can recall.

John McEnroe (September 2001): RTR Industries went out of business in 1986 but it is said that they still make speaker replacement parts. The RTR panels were used by several other brands:
RTR web site (January 12, 2010): RTR once made a complete line of high quality speakers running up to some quite large speakers, this back around the late 1960s and 1970s. Most interesting they made electrostatic drivers; some were OEMed out to other speaker makers (Infinity and Crown for instance, early ESSs too), some went in their own speakers and they also made two outboard ES tweeter arrays available to the DIYer. It appears they went under and some company picked up the name and is using it.
