Currently I have (4) Phonic SEM 715 speakers which state the following:
RMS = 230w
Program = 400w
Ohm = 8
I am looking to move into some more power, but I need to verify some things first. Would the following statements be true.
1) If I hook up all (4) speakers to the amp above, would I be pulling 150w per speaker @ 4 ohm each?
Any way to get more power out of this system?
The ability to drive four 8 ohm cabs to 150w per cabinet is decent.
Most of the noise is made by the first 100w, and many cabs won't go more than 150w before they fart out.
Jumping from 150w per cab, to 300w per cab is only a +3dB gain, barely noticeable.
Your cabs won't go 300 watts each, neither will your electronics.
Your speakers are rated at 98 SPL.
Replacing each with a D410-XLT would make the total sound almost twice as loud.
It would be fun to see your amp driving four D410-XLT at 8 ohms each.
Is this bass or PA use?
If PA, go horn loaded if you need more noise.
You will need a trailer and truck to haul the horns, so you might as well spring for big power amps, crossovers and a console.
It gets away from you pretty quick...
