    Nope lost the battle on those, they were affectionately deemed granny coffins, it went down hill from there.

    Yup, sold to a Seattle area TDL Reference Standard collector. They are in a very good home now.

    Disintegration of the foam port inserts with TDL RTL2s seem to be a common problem (& probably the same with others in the range). Does anybody know the type of foam that was used, & ideally a source?

    Strangely the inserts have gone completely on one speaker - not the other. I don't want to touch the other one just in case it takes offense & breaks down to crumb. Assume it spent less time in the sun :-(

    I've generated a template in CorelDraw & need some 10mm thick sheet to (hopefully) cut out replacements.

    Found a source of 10mm thick reticulated foam which is sold for facing speakers - so it's acoustically transparent. £5 for a 320mm x 220mm piece.

    Used the template to cut out a relatively "square" piece & then cut the radius corners to suit. I'm happy with the results. Not perfect - better if the template was a piece of plywood - but at foot level, they look OK cosmetically.

    Thanks. Spotted a pair at the weekend, in amongst a huge pile of other stuff I didn't recognise...

    Hi, I have a same pair of RTL2s with the same rotten foam issue. I'd like to know if it affects the sound or not with or without the filler?

    And, it is funny that my RTL2s ports are rectangular in shape, different from what's shown on your photo......

    Hi all,

    I've done a bit of experimenting on my RSPM Mk IV factory "Improveds", in other words "P" prefixed serial numbers that had the Reticulated foam inserts installed in the ports from the factory and I replaced them due to the dreaded foam rot. Honestly I feel that the foam chokes the enclosures and they sound better without. I sourced some 20 grade which is the coarsest grade that's made and all I can say is they improve the looks but not the sound.

    Strangely, only one of the foam inserts broke down & I didn't want to disturb the (glued-in) other one. So, I've never been able to listen to the speakers with/without inserts. I've not been able to detect any difference to the sound since replacing the second insert.

    The foam I used was very open, like the foam that it replaced, & was described as specifically for speakers grills. Not sure what "20 grade" is in the previous post. Assume it must be density.

    BTW, the speaker grills on yours look to be almost full height (except the ports) whereas mine are the upper 60% (approx). The plinths are different as well.

    a further search shows yours as a "RTL2 Special Edition":

    The 20 is most certainly the density grading. 20 is the coarsest you can get in reticulated foam. It is used for speaker facings and also air conditioner filter inserts.

    It goes up in numbers of ten, so there is 20 (being the most open), 30, 40 and 50 (being the densest) if my memory serves me correctly.
