+1. At best doubling the power will only get you 3dB, and you won't even get that if one amp already takes the driver to full excursion.Safe yes, advisable no. What's the point? what advantage are you looking for? If you want the speaker to play louder, buy a bigger watt amp instead of two smaller amps.
Well, as Mike P. and thxgoon say, it would be helpful to know which driver and amplifier. Without knowing that, I certainly think it can be a substantial upgrade going to a new driver without more power. You can get lower distortion, more excursion capability, better low frequency extension, better high end, etc.!Right, yeah I realize it is more complicated.
The reason behind this madness is I want to upgrade my driver but without more power it will not be any real upgrade. And the fact is buying a new large amp is more expensive than just buying another smaller amp.
1. I do not believe the claims because how come it magically goes from 230x2 to 500x1? LOL, I saw real world test that used a home circuit claiming 380 watts bridged.Behringer advertises A500 as producing 230 watts into 4 ohms or 500 watts into 8 ohms bridged. If you believe the advertised claims that's a lot of power.
Now, if you're going to add another A500 AND another driver to your system I can go along with THAT . . . . especially if the next driver is a Maelstrom-X!
However someone's gotta tell you and it might as well be me . . . . . as good as your plan might be and as nice as it might turn out to perform, the Maelstrom-X can handle MUCH more power than is available with the A500
Now I understand more your desire to try two A500s. I still don't agree but it's not my project.3. I know more people are going to tell me to just sell the A500 and get a "real" amp but I want to see this works first because I like the A500's ease of use, and if I decide to upgrade in the future I can use these A500's for Fronts and the Center if I need to. I am also a musician so these would make great little keyboard/bass/PA amps.
Now I understand more your desire to try two A500s. I still don't agree but it's not my project.
What I'd personally like to find out from your finished project is whether or not driving each voice coil of the speaker with these particular separate amps of equal wattage actually DOES/WILL double or increase the output volume. Electrical law says no but I'd like you to prove that for me.
Go for it.
