2 different subs, same rms. Which is louder?

Say if you had an IA DR, and a DP. Running the same rms like 900w through each sub in separate optimum enclosures.

Would the DP be louder, or would they sound the same because of the same power?

A lot more comes into play then just power... Such as motor force

Contact IA and ask them as they should have test results on all their subs at various power levels...

Yeah, wouldn't the DP have more motor force?

O that's cool, just something I want to know, cause I see people with subs way overrated for the amp and they say it's better than the previous lower rms model of sub.

I'm matching the rms of the DR I just ordered today.

The one with the better box.

Same box.

Same car.

Same size.

diff power handling and other ****

Probably a barely audible difference. The one with the lower power handling will probably move more, displacing more air. But again, it would probably be hard to notice on music.

as said alot comes into play. box eff and sub eff. most good 600rms subs are underated and at rated power you arent using them to the fullest. this is done to protect a company from inexperienced installers...
