I have been thinking about it!
This problem keeps cropping up;I have had many requests for equipment to improve listening on TV.
Presently, and partly as a result of these requests, I’m working on the development of a new TV loudspeaker (working title TVTR) which will be a simple low price device, but fitted with a form of filtering and compression specifically to help with perception of dialogue. By definition this will help with listening to all types of sound where the dynamic range is too great or where there is interfering noise.
The new loudspeaker will be under the Orbitsound label and should appear mid next year.
