Ok, heres the deal, I have a Paradigm Reference Survo 15 sub, (is that a good sub? - it thunders, but I have some technical questions), anyways, and I have a set of Paradigm Studio Reference 40's for my back channels, and some "other" speakers for the mains, and a Paradigm Reference CC-350 center channel. 1st question: I have the sub controller with the sub, ok, now, where should the volume on the BACK of the sub next to the heat sink be set? At full, at half, or somewhere in between, I mean, I have the X controller that came with it too, and I have never really discovered where it should really be set. Also, I don't frequently run my stuff REAL hard, but how can you tell when you are approaching the subs safty point, before the internal amp starts to clip, or the cone bottoms out? 2nd question: For those who have these 2 different types of speakers, is there any serious difference in between the cc-350 and the cc-370? And what are the differences between the ref 80's and the ref 100's - in other words, theres a $500 dollar difference, but which one would be worth it? 3rd question: I have a Yamaha RX-V1 preamp/processor and a Sherbourn 5 channel power amp. If I get either the 80's or the 100's they will be like the 40's, and you will be able to bi-wire them right? I've done this with my 40's, and it makes a difference, however, would this be constituted as a 4ohm load instead of an 8ohm load, I mean, you are using 2 seperate amp channels, but with both going into the same speaker, does that make any ohm difference? My point for this is, I want to use 2 channels for the left, 2 channels for the right, and the last channel for the front center. Would there be a difference, in the sound, do you think, since all channesl are going to be used up, then the back channels are going to have to run off the Yamahas internal amps for those particular channels? And would getting another Sherbourn amp, and bi-wiring the back channels also, make any diffefence in the total Dolby Digital experience? And does the type of wiring used make a serious difference? I've seen wire all the way up to $12.00 a FOOT! Using that in a HT setup would be EXPENSIVE! I know this is a lot of questions, but I am some what of a new comer, and there is a lot I still need to learn, I got screwed over BIG time by a nameless company in the Memphis area, and so now, I am in the process of dealing with that, and picking up the pieces, and I figured that Paradigm would be a good way to go. Is Paradigm Reference WORTH the money? Thank You.
