my ideas, we have time so could try afew configrations out
but for starters
mid/top amp = caudio pulse 1100
kick = matrix xp3000
sub = matrix xp 5000 [run 8 ohm stereo NOT 4 ohm bridge. OR 4 ohm stereo running the 4 21"s]
there is no need to push the amps hard if you dont need too. the mx1200 will be more then loud enough with 1200wrms each. one box one channel is a nice safe way to run it, we have the amp power why bother taking short cuts?!
Yes mate that's the shizzle homeboyz!!! We have amps galore shipmates, your right to run the subs in bridge mode at 4 ohms. I have two wicked 3k C-Audio bad boy amps for that that we can use do the job each leaving over a k of headroom. Don't forget the twelve BS600's.
Heathrow your artwork is wicked mate. One of those stacks will look soooo fresh, i've almost finished refurbishing a complete stack after weeks of work, looks better than the day they left the factory, all in dark grey, perfectly smooth, no grills, just open bellowing box's, and on the 'opened' MX600's the phase plugs look sooo cool, loads of people on the industrial site in the countryside where the barn/unit is dig the cabs as i work on them, asking me what they fuk they are, even the farmer in the tractor who owns the land where the units are was well interested.
Speak soon, and thanks again for your time.
