I would like to get a decent pair of speaker for my Separo SE88i that I have recently purchased. It is only 8WPC. The speakers I have looked at are the Monitor Audio BX2, BR2 and RX2. Can anyone advise as to which out of these three options would best suit my Class A amplifier; with a view to producing a decent amount of volume. That is without exerting my amp to much. Any advice is most welcome.
