hello, just ordered a Yamaha RX-V871 AV receiver and will be in the market to start building a speaker system to go with it. the speaker brands i generally know of, paradigm, klipsch, and one that ive heard of but never used, Axiom. But after doing some looking around on the net today, i came across the BIC America line, and for the price, it appears they have some amazing speakers. I'm just wondering if it's too good to be true. Looking for anyone who has ever heard the bic speakers. I would probably be looking at the BiC America brand and not the Acoustech, because im not sure how I would like the horn tweeter, and would probably defer to the dome tweeter. anyway, the lineup im looking at would be from: Axiom Paradigm Klipsch BiC feel free to throw in some other decent ones if you like...ill be looking and try to read up on them to see where I should go with this. also, in the SW department, aside from the BiC subs, which seems fairly good, i was looking at SVS, but their prices are a bit high. other options would be outlaw audio, axiom, lava subs. also, how do you know when you need a ported sub, or a sealed sub? what is the difference? when choosing surrounds, how do you know when you need normal speakers, dipole, bipole etc. also, somethign ive wondered about, why do they use full floor standing speakers for the fronts and the small bookshelf speakers as surrounds. Would it be possible, and even better to use full floor standing speakers for your mains AND surrounds? just curious on that one thanks. ill try to make a diagram of my living area and post it so you get a better idea of what im dealing with.
