Directive amps

Anyone here have alot of experience with "Directive" amps? I've been doing some reading and found they have a hybrid 5ch amp that has a higher wattage per channel to the 2 front channels than to the back. I like this as I really don't want as much power going into my rear fill speakers as I do the fronts.

I have Boston Pro 6.53's in the front and Boston NX67's in the rear fill. The 6.53's are very power hungry, so if I want, say 100w into each of them, I certainly don't want 100w into my rear fills (although they are rated to handle that as well).

Perhaps if not Directive, there's other "hybrids" that offer a watts per channel offset that reflect the thought of a "system" design?    

I meant DIRECTED amps.

Its late.....my mind is soup 

God I wish I could edit this.

I think what I'm looking for is something like a JL 500/5 - an amp that offsets the higher wattage to the fronts and less for the rear fills. Can't remember what the offical label for those style of amps are. I knew of the 500/5, just wanted a few more to look at before I shelled out any $$$. I don't have room for multiple amps either - unless they are smaller. If the 500/5 is my only choice, even its size is going to be a challenge.

And yes, I have read the forum guidelines. I just think its peculiar that I one has to post x amount of times before they can fix a typo.

Summed in one word:  Initiation.  Word is it will become much more severe in the near future

I did check out the Memphis Belle's.....my friend's got one and loves it, but they still all look to be equal wattage x 4, etc.  

If I have to find smaller ones and use multiple amps, I may just do that. Not my first choice, but circumstances - and space - may dictate I do.

I'd just like to get some power into those Bostons.

Check Soundstream davinci,it's 7 ch.

50 x 4,100 x 2 + 200 x 1 at 4 ohms

100 x 4,200 x 2 + 400 X1 at 2 ohms

the sub ch. can handle a 1 ohm load - 500 watts
