Default Overhung coil - too much?

Is this much necessary? Seems to me that sensitivity would suffer terribly. I think these 13 cm drivers are rated at 81 dB. Is this a bit much for what they are trying to achieve? Help me with your wisdom.

I'd be looking at underhung in that cup style motor, like the aura drivers.

Is it a car audio driver?

If so, it seems they like that sort of thing--sensitivity is not a concern. What is the Xmax on that thing?

Thanks guys.

81 dB for a car driver? Not sure of the Xmax, I would guess 6 mm?. Ich spreche kein Deutsch.

I'm not really sure what to do with these things.

I notice the Aurasound are less than $4. Unfortunately that doesn't do my heart any good.

Maybe a good match for the Aurasound 3" full range driver to be used as a tweeter? The 3" full range has a dismal 80dB 1w/1m.

6mm of Xmax for a 13cm driver is pretty stout, throw in the Aurasound full range for 200Hz and up and you'll have some seriously jumping cones. Might be a good solution for parents of teenaged kids (like me) that like to watch cones moving back and forth. At least it won't smoke their or your hearing. Such is the price you pay for maximum "flex".
