REL was one of the brands that I liked at for my Vienna Acoustics speakers. At the time they were also carried by Sumiko and were considered a good match for the Vienna's. However, I ended up going with a JL Audio f112 and have been quite pleased with it.
REL G2 or JL Audio F112 ..thoughts for 2 channel
I have a pair of Sonus Faber Cremona M's floor standing speakers.....they go down to 40 hertz.......I was thinking about adding a sub in a room that is about 11' across and 20' deep with a 7' celing.....the speakers are on the short wall. The room is all ASC treated. I do not have all that much room on the side or in back due to Purist Audio cabeling......but it could be worked out. I have heard that the REL G2's would go well and yes I know they are both owned by Sumiko.....your thoughts
