wow great responce here!
this is my plan:
the gx 3 will power the front left and right towers cut off at 100Hrz
these are the mids and tweeters
the tweeters are dynaudio md330
the woofers are eclipse 6.75" drivers
i am going to use the mx1500A for the woofers in those cabinets. (bi-amp)
then use the rmx to power the subwoofer.
the blue monster has a very stiff suspention on it 2 spiders. you could I/B if you want. the coil is under hung 4" 8 layer dual 2 ohms. dc resistance is 1.6 per coil.
it only needs a 2 cubic foot box ported. i was thinking 6th order band pass.
As for building speaker box building. I worked in a car audio shop for 4 years. i did mdf boxes, fiberglass, plexiy glass. honestly that where all of the speakers are from.
I got all the wood working tools any one could ask for. the audio shop is right down the road. they let me use the wood shop when ever.
the back or surround speakers are going to be dynaudio 7" drivers and the md330 tweeter. i will keep the b&w center channel for now.
i say 4600 but i will never peak that. i just want to be able to push it evey now and then with out killing any thing.
to mdocod you can never have to much power buddy! amps run way cooler than one that was matched rms to rms of the speaker..
when i had my sq car audio set up i had 4 times the power on every thing. 145 db and you could here every thing. i even have a dash mount RTA. 6 audio control EQTS. only cross over in the car where what was in the amps. never popped a speaker
