Default Quick question about the Pioneer B20 8" driver

Does this driver work well with a cap and tweeter because it has a gradual roll off? The frequency plot is shown here from Parts Express: http://www.partsexpress.com/pdf/290-045.pdf

I've had good success with a cheap 1/2" tweeter and a 1 uF cap
to sweeten the response above 10 KHz. Easy to do, instant
gratification.

Thanks Nelson. Sounds like it will be easy to make a good sounding system with this driver and a simple tweeter.
