surprisingly my room size changed overnight
but after reading thread here yesterday i actually measured the room dimensions using laser tape..hope its accurate

thanks once again....would EP 600 be too big ?? with the surrounds will it be too much if i purchase the floor standing speakers say for eg either the M 50 or 60 or perhaps even the 80s
the receiver i have is for 5.1 setup so if i want to have 7.1 i will need to purchase receiver with 7.1 set up.
may be i will try my current receiver first and if i want to upgrade later to 7.1 will buy the additional speakers and the NAD T773..
what do you guys think

In a room with a 25 ft wall and a 12 ft ceiling, I'd say that EP600 would be good. I don't understand your second question, but making a guess, I'd point out that most people use the QS8s for surrounds with their 60s and 80s. Those of us with 50s do various things--one guy uses M3s, I use QS4s, I think someone else uses QS4s... and that's all of us!

what i was getting at was, do i have to use the QS8 for surrounds or can i also use the M 50, 60 or 80s as surrounds. and if i do it, is it an overkill ? i would like to use QS8 for surrounds...initially in 5.1 setup followed by 7.1 setup
thanks for your input

>>would EP 600 be too big ??

There's "too big" as in "too big to work well in your room" or as in "bigger than you need; a smaller model would work just as well 99% of the time".

Believe it or not there isn't all that much overlap between floor standing speakers and a real good subwoofer, since you normally run the speakers in "small" and cut them off at 60-80 Hz. What the big speakers give you is the ability to play loud and clear in a large room; even the biggest "reasonable" floor standing speaker isn't going to do much down in the "real" subwoofer frequency ranges...

There is obviously some overlap in that both sub and M50/60/80 are capable in the 40-100 Hz range but that's not what you buy a good sub for in an HT system. Down below 40 Hz (where all the fun happens) none of the floor standing speakers are in the same league as even a midrange sub.

For music it seems to be a different story. Some people buy subs to get insane amounts of bass at higher frequencies, say up to 80 or 100 Hz. In that case there IS a real overlap between sub and speakers.

I still tend to turn my sub off for most music -- the M60s go as deep as I care for 99% of the time.

>>what i was getting at was, do i have to use the QS8 for surrounds or can i also use the M 50, 60 or 80s as surrounds. and if i do it, is it an overkill ?

Ahh. For movies, the dispersed sound from the QS8s is generally preferable to the point sound of the regular speakers. For music, I still prefer regular speakers a bit over QS8s. Most people go with QS4/QS8 as the best all-round solution -- people who buy regular speakers for surrounds tend to go with bookshelf models because there is generally not much LF content in the surround channels. A few have floorstanders all round and get great performance but they seem to play at louder SPLs than the rest of us.

Some people have commented that there is an advantage to having surround speakers that can play down to lower frequencies than the QS8s, although there is not a lot of agreement on this.

my question was in regard to, whether too big for my room and do i need all that bass for watching mostly action, special effects movies and listening to jazz, string intruments, classical indian music with lots of harmonium and tabla.

For your room size either Epic 80 package would do a wonderful job for you.For action and special effects movies you would want as much subwoofer as you could afford too.With your selection of music I would say the 80s could handle jazz pretty much on their own.As far as harmonium and tabla you lost me on that one

I typically do not get into wether or not 'this' or 'that' may be too much or too little for other's listening habits, but I will say that sometimes common sense and what your particular ear likes may just very well be the way to go. I like listening to bass for both movies and music so therefore I don't mess around with the sub too much but if I feel on a particular song or cd that the bass is a little too much I'll reach behind the sub and turn the thing off...easy fix.

thanks for your help... harmonium is like a key board which uses air to make sound...and tabla is basically two small drums (like bongo/congo).
i think will go with Epic 80-600 series. thats the easy part
now to get the wife to agree to all this !!!!!!!!!!! thats another issue all together!!!!!!!!!11
