What design features allows one coil to handle 500++wrms and one to handle only 200wrms???
impedence? Magnet size? etc???

Size of coil, material and how many layers
material and surface area
Heat dissipation properties will play a small roll as well, as a flatwound coil will be able to dissipate more via its design/shape, as opposed to a heavy gauge 8-layer round wire coil. More surface area ftw.
Hey there neighbor. Crazy, we must meet up some time!Quote:

Absolutely. You can't have a coil baking inside a motor and basket structure that doesn't want to allow any cooling.Quote:

A high powered driver, or coil in this instance, needs a powerful motor to help with controlling and keeping it inside a certain portion of the gap so the power sent to the coil isn't simply heating up the windings as it sits static, rather, turning the power through the coil into mechanical energy ie movement and eventually acoustical energy. As well as other types of mechanical and heat energy, but those are what we are NOT after. We sound efficient drivers that make sound.
But along with the movement thing, basket design, spider diameter, surround capabilities, and excursion as a whole plays a role too.
Speakers are very finely designed and fine tuned machines.
the thermal cap comes down to the coil and the cooling of the motor.
example; take 2 exact coils with same spiders and cones. put 1 in a dd9500g then other in a re audio sx. the 9500g will handle 500-600rms more power due to better motor cooling...

Are the difficult design parameters the reason why dual voice coils subs exist? This way you can have a 600wrms sub divided by two coils to prevent too much wattage through a single coil, right?
no, dvc exists for the purpose of allowing different wiring configurations in order to wire your amp as low as it is stable for, to get the most power out of your amp. less resistance = more powerQuote:

So just because a sub woofer has 2 voice coils, doesn't mean it has more power handling ability than a single voice coil sub?
Then why do some manufacturers advertise a single coil sub as having a 250wrms capability, then advertise a similar dual voice coil version as having 250wrms EACH?
you can only fit so much coil into the gap and be the same clearance and etc.
I've never seen that... Can you show an example.. bit no as others said a dvc is only useful for wiring options. Actually I can post hundreds of examples of subsbthat have a svc and dvc option that have equal powerhandling
