No, you probably won't. But, limiting is not optional, and don't bother with any sub-synth, either. Just make sure all your subs are the same polarity, that you wall or corner load them and use a V-plate, if you can. All this adds up to free SPL.
Groups of less than four cabs should be high-passed at 45 Hz. With four cabs or more 40 Hz is acceptable. High pass filters are contained in many active crossovers, and both high pass filters and limiters are in loudspeaker management systems like the Behringer DCX 2496 and DBX Drive Rack series. Some newer amps also have on-board DSP with these features.
This is what my plans read. Also they say 55v limiting. Once again I am fine with 50v as I doubt I'll need all of it. I have 0 experience with these speakers thus I appreciate all the help, but i wanted to build these because 40hz should be adequate for our purposes. Also I wanted to keep the subs small but still reach low end. Plus I scored 4 Lab 12s for the price of 2
. T48s are not an option right now. Did I mention right now
In a perfect world I'd love to have a system like Seth Green in "The Italian Job" or "Doc" in "Back to the future".
You think the 2500 will not be enough? I should then go for 1000w/channel at 4ohms or 63v+. Maybe I'll just stay with my drummers ep4000, which is supposed to do 75v+/channel.
