Which Rel subwoofer


I have a pair of Dynaudio C-1 and I'm trying to figure out what Rel sub to use. The two I'm looking at are the R-218 and the R-328. Does anyone have any experience with these Subs.

I combine Dynaudio 1.3SE with R205 (succeeded by the R218 I think).
In my room (rather small : 24 m2 +/- 250 ft2)it works fine.
If your room is larger and presuming the C1 has better bass than the 1.3SE, perhaps the R-328 is a better choice.
All I can say is I've had several RELs and had reliability issues, stay away from REL!
Sksos1,

There are a large number of REL models out in the world. Which did you have issues with?

And how was support from REL when these issues did come up?

Loved my REL Storm III when I had need of it. Best sub I have owned to date. (But also the highest end sub I have had to date).
