I have looked but cant quite find help setting limiters.

For T48s with 3015LF,
Max RMS 450 Watt, but previous posts and perhaps plans even suggest 300 Watts target level.

Volts * Volts/ Resistance= Power
Substituting 8 Ohm, 312 Watts gives a nice, round 50 Volts for my target output.
Which, incidentally, gives me 6.24 Amps unless mistaken.

Here is my question. With the above target voltage of 50V, how to I set my limiter/ amps to make sure DJs don't make smoke?
Using a DJ mixer->Ashly Processor (24.24M)->Amps

I will suggest my setup method, and let you guys point out where I'm mistaken or suggest better methods.

Bink audio test CD playing 50Hz into DJ mixer.
Channel volume 100%
75% main (Master) sent to processor
Limiter set at ( FILL IN THE GAPS PLEASE!!!) settings
Amp gain set corresponding to 50V tested at amp terminals

Thanks in advance for any help!

Use your high pass frequency, where the driver will use the most power. If your HPF is 40Hz, run a 40Hz sine wave with the gains set at maximum everywhere in the signal. Attach just the volt mater to the amp outputs, adjust the hard limiter at your 50V limit, so that no matter what you do, 50V is the maximum you get.

As far as how to set the limiters on the Ashley, sorry, but it's in the instruction manual.

Thanks for the pointer regarding the 40Hz instead of 50. Makes sense.

So with or without the speaker in the circuit, voltmeter would read same, due to Ohm's law, right? V=I*R (Less resistance, higher amps, but same voltage)

Without the speakers!!! or you'll blow your ear drums out!!! The solid state amp won't mind abit.
