My setup consists of MA RX6's, RXC AND RXFX's hooked up to an Onkyo 809 and using a Bic Acoustech PL200 sub. The room is wired for the four rear speakers but just have a 5.1 setup for now. My room is a dedicated room that has a treadmill as well lol. Dimensions are 11w 19L and 8 h. For the size of my room the Onkyo handles them well. I have the speakers in rosenut and prefer the grills off. The contrast of the rosenut and white woofers is pretty sexy. If anyone is considering getting some RXs go ahead and you will not be disappointed. If you are running a sub or going to be, opt for the Rx6 and use the money saved on a better sub over an Rx8. They are both great speakers and I prefer the rx8 longer grille cover length over the one used on the Rx6. My sub is a cheaper sub that sounds pretty decent with music but outstanding for movies considering the price to Canada was $350 everything included.
My previous setup consisted of Paradigm Monitor v5. I had the 11's, cc290 and mini monitors. I sold them to help fund the purchase of my new MA setup. I love the fact there are no screws to be seen on the speakers anywhere. Nice and clean looking. The new Paradigm Monitor series 7 speakers seem to take a cue from MA rx line as they have cleaned up the front baffle as well. I have not heard them yet though.
I auditioned comparable speakers from PSB both the image and imagine lines, b&w 600 series and cm line, axiom vp 150 and m60 v3 and sent them back paying the shipping
there are many to choose from in this price range but for me I was most impressed by MA's quality even though it's made in china, the design is clean and looks fantastic and of course it sounds great to me at a price I was willing to pay. I like to see my dollar being stretched as far as it can go because at the end of the day it is a pretty good chunk of change to plop down on a basic 5.0 setup. My other favorite would be Paradigms Studio line. I still preferred my MA over them but they are pretty impressive as well and pricy.
I also agree with others saying to look elsewhere in the sub department. For the price of a MA sub you can get some amazing ones from SVS, HSU, OUTLAW, EMOTIVA, PARADIGM, Elemental Designs etc.
Anyway I enjoy my system very much and am lucky to have a dedicated room in my new house I built. With that being said I am always curious how other systems would sound in there. Lol.
