My front (its a 5.1 system) speakers cost about $300 each and a full floor standing units, they are very loud, the centre is a mordent short speaker and it is probably the best speaker I own (not including some McGregors) it sounds awesome and cost just over $200. My rears and a pair of cheapish missions. The Sub is Hardon-Kardon and is so bassy, it just totally rocks.
My McGregors are Wedges and they are more powerful that all my speakers put togethor (well, maybe not but they sound like it
) but I only use them when doing PA or when I setup my projector as a cinema screen
