Impedance Correction in Single Drivers
 
Hello friends. In the world of Multi Drivers and of Crossovers, the Impedance Correction Circuitery called "Zobels" is of importance to flaten the overall impedance of driver(s).

my question is;
How important or not, is the same circuit in a Single Driver situation. Would having one take away from sound quality?

Thanking you in advance,
Vilic

It depends on your amplifier.

If you have a hi-Z amp or a large BSC filter, you can use a series resistor and cap to tailor the high end frequency response. But it is not a zobel per se because you are adjusting for the FR shape, not the impedance shape.

I have found that you can get a nice flat impedance curve on a fullrange with a zobel, at the expense of some top end roll off (not usually a good thing). If your driver is really HOT on top, this may help.

Hello again and thank you very much for replying. The story is that I want to build a small TL with a 2" Tang Band driver. (W2-1803S) I do not want to add any Xover component if I can. But, if I have to say add just a cap to cutoff the low end (to protect the driver in higher levels of volume), how much of sound quality loss (i.e. staging, transition...) I should be expecting, using a regular transistor amp?
Thanks again,
Vilic
