Hi there. I'm finalising my decision on a pair of in-ceiling speakers to go with the rest of my new set up (Acoustic Energy ) and have been quoted £100ish for a pair of Opus OS150 in-ceiling speakers. Anyone know of them, and have anything to say on quality? Apparently they are made for Opus by Mordaunt Short but other than that can't find much at all on-line. Alternatives are Acoustic Energy's own, but they would cost an extra £50+ and budget is already getting stretched!! They do have directional tweeters though As they are for rear channels, is it too much of an issue what I go for?? Cheers.
