No, a first order lowpass typically has a coil in series with the driver. Just a capacitor in parallel with the driver will not be healthy for the amplifier.
It is possible, but hardly clever, to use a parallel capacitor combined with a series resistor. This will attenuate the signal in the passband by 6 dB.

The diaural XO differs from a basic series XO in that it adds a power wasting resistor in parallel with the woofer. (it did get them a patent & lots of hype)
To use a cap as a low pass filter you need to have it and the woofer in series with something else that ensures that the amp has something to drive above the XO frequency. (ie a coil & a tweetre in a basic series 2-way)

LOL! Is that what all the hype was about? I remember reading about the amazing circuit that was going to revolutionize the speaker industry, and countless raves over some little demo speaker that outperformed the big boys. Then suddenly..... dead silence, no more talk about DiAural crossovers.
Your post brought up a few questions, so I did a search and found this. http://www.diaural.com/, which pretty much answers all of them.
