As stated in my sig, I have had a set of JBL Music1's as my mains for a while now. Since I added the powered sub, they have been fine. I've been searching all over the place for another set of Music1 satellites but until last night was unsuccessful. I found a Music10 set last night. same sats different sub. What I'm trying to figure out now is, is it OK to have an array with 2 sat & 2 subs for front, 2 sats and another sub in rear, AND a powered sub? or would I be better off leaving out the passive subs? I mostly watch DVDs and I'm assuming all the .1 info is going to the powered sub. But if I do that, my L/R front & rear will no longer be full range capable. The sats only go down to about 180Hz.

For the best bass, stack all your subs in the best corner of your room. I'm not sure the response of your satellites but if they can hit 80hz you should be fine with localization.

Otherwise, stack your three in the front and put one in back. Run your mains as large and use the crossover in your sub to reroute the higher frequencies to the fronts. Run your rears as large and do the same with the rear sub. Keep the center as small though....

But having a seperate sub for each channel is usually not a good idea because of room size, cancelations, humps, and other wierd things that bass frequencies can do.

That's why you use an RTA to determine what frequencies have the most significant dips and peaks, and remedy that by adjusting sub placement and or by using an external EQ.

Sure that's possible and probably recommended if you were to have 6 subwoofers(one for each channel). But the best way is to get the best sub you can(maybe two-stacked) and just run everything as small and let bass management handle it.

Then there's also room treatments to help with bass response but it might mess up the 'decor' of the room...Not a problem with a dedicated HT room but can be somewhat troublesome if HT is in a main/great room..Spousal Acceptance Factor and all that...

In the situation at hand, with limited capablility sats, stack the three subs in the front. Then find the best spot in the rear of the room(preferably in between the two rear speakers since 180hz is certainly localizeable) to place the rear sub.

It's most adviseable to get speakers that can hit 80hz with no problem....You should be able to find several different brands for around $100 for the pair....
