Hello , I am planning to make a MTM 3-way active speaker run by a dsp. Using 4 Dayton Audio TCP115-4 , 2 for midrange in a sealed cabinet and 2 for woofers in a passive radiator cabinet. A Dayton Audio RST28F-4 Tweeter for highs. I'm thinking about using 3 Amp Camp Amp's to run it. I will be using it as desktop speakers. I'm sitting not even a meter away. I'm looking for impact and punch. I know class A is known for great control. Do you this will be a good pairing? also will be my first amp build. The speakers will be paired with a 18" 700w rms subwoofer. And if you see any problem with the speakers please say something too , it's only my second speaker build. Thank you in advance.
What power supply are you planning to use? Will the amplifier be designed as a separate unit or built into the speakers? Which amplifier will be used for the subwoofer?
The 24v power supply., It will be seperate from the speakers. And I'm using a 700w RMS plate amplifier for the subwoofer.
Draw a block diagram from rectangles (devices). Connect the blocks with lines with arrows how the signal will propagate (split). This will help you understand the rational layout of your system. Check that the input and output levels match the input and output impedances.
Consider power and system management separately.
The selection of the characteristics of the individual units depends on the general requirements and structure of the system.

I'm using a pair of ACA's with a bi amp 6-24 Xover and only run out of power with low impedance drivers. They play loud enough for regular listening levels at about 8 ft from the speakers.
Is that the sensitivity? the impedance is more like the load on the amplifier (simplified, be nice). In normal configuration (Stereo with rca input) the ACA works better with 8 ohm loads than 4 ohm loads to my ears. You are asking about using multiple drivers to make your speaker, so the way they are connected together will change the impedance the amp "sees"
Simply stated wired in parallel lowers the impedance while wired in series raises the impedance. Two four ohm drivers in parallel will not work well with the ACA while two four ohm drivers in series will work better.

The ACA is, by design, a low power amplifier, and won't keep up with a 700W sub amplifier, especially with low-efficiency drivers like that.
