you have not said what you are using these speakers with(amp) and for what(home cinema or music).
Do you intend to use in a stereo or 5.1 home cinema configuration.If so what other speakers are you using.What size amp are you using and what sort of sound do you like.What budget are you looking at.
The mission M71i are truly excellent speakers for the current Richers price of £59.00 per pair (birch finish only). If you search the net you will find quite a few reviews on these speakers.
I bought a pair of these from Richers in black for £49.00 a few months ago.I use them as a pair of main speakers in my 5.1 setup in the conservatory and use some gale speakers for rears and centre.They are the best speakers available at this price level!
