All right, i've been scratching my head on this one, but i just don't know...


Situation:
if i have a DVC Sub and each coil is rated for 250w rms... that means to avoid frying the sub i can only power both coils to a max of 250w... which means a single 250w rms amp wired to the single DVC sub... (For the nit-pickers, assume that you've wired it so that the amp sees 2 ohms from the sub and is ok with it)

Now if i have a SVC sub and it can handle 500w rms... wired to a single 500w RMS amp... (For the nit-pickers, assume that sub is 2 ohms)

Questions:
wouldn't that mean that the 500w rms SVC would pump out more bass?
True the DVC has an overall 500w rms, but that's split between 2 coils. Wouldn't that 2 coil split behave just like having two SVC 250w rms subs (Meaning it really only was pumping out 250w rms worth of bass, overall)? (And we know that when you add a second sub it only increases the over all 'loudness' by 3db)

My guess: SVC 500w rms would beat a DVC 250w rms sub... But I'm not confident in my guess....

Ok, i feel stupid... I just got my answer:

"[An amp] must deliver ten times as much power to double the subjective loudness."
- also -
"If a sound gets louder by 3 decibels or "slightly louder," it takes twice as much electrical power from your receiver or amp to produce that modest increase. Therefore, a 100-watt amplifier will produce sound only slightly louder than a 50-watt amplifier."

Which means, it doesn't matter how you add power to a system, via a single SVC 500w rms or two SVC 250w speaker or one 250w DVC speaker ... twice the power will only give you an extra 3db....

Any day you that you learn something new... That's a good day.
