Fix those broken RSL Speedscreens!!
These were used to repair my 30 year old RSL Speedscreens as a present to my son. The kits were complete, easy to utilize and very effective replacements. Everything you need is in the kit. By the way, my son loved the speakers. He had seen them before growing up and was told they were 'broken'.

I've got a pair of RSL speedscreens that are pretty old. Very cool speakers with a passive radiator that basically disintegrated over time. They still sounded good at low volumes.Came across the Simply Speaker website and saw the radiator kit that would fit. I put them on as soon as I got them. Very easy without any wiring. It's like they're brand new speakers! Thanks

These passive radiators are well made. The instructions were clear enough and installation went smoothly. The only problem I had was that the old passive radiator had one layer of cardboard behind the foam and these new ones have two. That made the moving mass greater, even when taking into account the tuning mass glued onto the back of the old one. That makes the tuning frequency lower and with no means of raising it. The system still sounds good, though, just different.
