I believe there made in Wales if I’m not to mistaken.
The cabinets are made in Sheffield, but Rel Acoustics itself is based in Bridgend, South Wales (just a short way from where I grew up and only a 5 minute walk from where I spent some years in tech college - for some reason that seems weird - that's weird they were so close not that I went to tech
).
A friend bought a used Rel Storm to use with his B&W 805S - 100% music - and it seems to integrate very well with them in his room, which is very lucky as it's a primitive sub without much in the way of adjustment possibilities (but it does have a remote!
). Strangely though, or maybe not, he couldn’t position it in his preferred spot as the sun would be on it during the morning (he’s the type who likes to keep things switched on) and it would overheat and go into protection mode just sitting there doing nothing – oh, the wonders of inefficient MOSFET amps.
When the winter starts closing in we're going to take my SMS-1 over to his place and really have a look how well it actually does integrate.
Unfortunately, from what I've read, I think Rel and their products have a little old school audiophoolery attitude associated with them; a lot of the audiophool snobs will tell you that Rel subs are the best for music. Admittedly, from what I've heard of the Storm they aren't bad for music but really, generally speaking, pay this sort of money for any sub these days and music performance becomes mainly an integration exercise. For HT you can get much better subs for the price.
