So I ran across something I've never seen before and would like someone with more experience to explain it to me.
I have a pair of Dunlavy SC-1 speakers. The design uses a pair of Vifa P13WG-00 8ohm drivers in parallel.
It's a first order design, so only one coil. The coil has no value marking on it but I know it to be crossed over at 3500Hz.
Here is the confusing part. The circuit has a zobel (2ohm/2.7u). But instead of paralleling the drivers, which is what I have always seen before, it parallels the coil.
Why?
Looking at the impedance/phase measurements, it is obviously preventing the impedance from rising in the upper frequency of the driver's operating range.
What difference does this design make?
Thanks!
