I just want to start off by saying i not a fan of Cerwin Vega speakers,But that's my personal opinion ,They look big and powerful(look nice with red trim) but i never did like how these speakers preformed and i don't like paper woofers .I also believe in having all your speakers the same(sub you can look at other's)But sometimes you get lucky.I have old mirage front speakers and found older energy speakers go very well with them.Bought new Paradigm center ,back surrounds and sub.But i've been lucky to test many speakers in my theater room.You can mix and match but you gotta have a good ear and some patience(and also helps if you have spec's and some reviews in front of you as well) .If you have a couple higher end speakers your pretty much sticking to high end for the rest(slowly pushing low end speakers out the door).But it's easier to keep speakers all the same(it's a safe bet) i just have to much time on my hands(Praise the lord) This is my 2 cents good luck
