neither . for a room that size the stadium 3 would be the starting point. there are a couple of stadium 3 for sale on this site now. i just sold mine but there are others . the reason i know this is i have talked to sumiko the distributor of rel and a room that size would be the stadium or the stentor. rel also does not recommend 2 subs just in case you get advice to do that. i already asked them
REL strata vs. storm and room size
I need some help. I have B&W sig 805's with a Trivista int amp, and I want to add a rel sw for 2 ch. music only, it will not be used for HT. My room is 18x20. Will the strata be the right size? or should i go with the larger storm. I'm not a fan of booming bass, but I would like to hear more of the lower end that I know I'm missing now and it seems that rel owners are very happy with their sw.
thanks.
thanks.
