I have some RL60.2 speakers in the bedroom, so I will take one of them to Radio Silks next week and ask them what comes closest to that for you Henri
That would be absolutely fantastic. If you really would do that, I'd appreciate it very much - I used to take my old RL60:s with me to my summer cottage a couple of times a year so I have some first-hand experience that they're not the easiest speakers to haul around.
I just checked the RL35:s, drivers are fine (not prone to foam rot in the first place?), the white edges of the housing are slightly scratched so I'll probably mask & respray them and frets look even worse from the inside than they do on the outside. I've also sketched up prototypes of RL35 wall mounts, I'll have to weld together a prototype to see how it'll work; I really can't figure out why the most obvious candidate for wall mounting, ie. the smallest speaker of RL series, isn't wall-mountable by default.
Let's sum up this speaker cloth issue so far:
Penta: Generic, 100den+ matt satin Lycra
C/CX: Shear poly blend, Jersey / Polo shirt fabric
Redline: TBA...
P30/45/50: ???
3000/4500/5000 panels: Find a wino, mug him, get the well-worn gray shirt...
As a sidenote, replacement bands for RL-series are still a problem. Heavy duty packing band that was mentioned in another thread might work, the width on RL35/1000 is 5mm, the same as narrow "standard" metric band. I'd suppose the band on RL45/60/140 is close to other standard widths too. Finding a source that will supply anything less than a full 1000m roll of it can be difficult, though.
