Quick question about the Pioneer B20 8" driver

davidallancole · 29th September 2007, 12:26 AM

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

Thanks guys, not quite the answer I was looking for based off the question, but I will read through the thread and see if my answer is in there.

The short answer is (opening the envelope)............. yes.

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.
