recently, a friend asked me why i bought two floor speakers for my fronts, a center, and 4 surrounds instead of just buying 6 same sized speakers and a center. my answer was b/c i started with just the 2 fronts as stereo and then added on. This made me think however what advantages/disadvantages a setup like mine has opposed to set of full range, all samed sized speakers (such as the new SVS i posted recently) Ive noticed that almost 100% of all posters here that i think of as helpful and knowleagable have a setup like mine and not a HTIB type setup. Why is this?? (if you can buy fullrange bookshelf speakers)

ive often wandered how much more work the fronts do in movies compared to the surrounds and if this is why its important to have a more full range set in fronts. Is there any type of percentage played per speaker in movies or maybe what percentage is sent where in a dpl IIX or pro-logic scheme?

its obvious that for a stereo setup, 2 nice fronts are mandatory. Also, what exactly is a moniter and the difference betweenother types?

The new SVS set really got me thinking b/c their bookshelves go flat all the way down to below a 80hz crossover for every speaker. Is this just an exceptional setup and perhaps a trend setter opposing larger, full ranged fronts? or am i missing a more important reason for the fronts being larger and having more woofer/tweeters ect?

all the above also is assuming the use of a sub for under 80hz
