1st order crossover design!

davidbosch · 24th March 2008, 09:51 PM

Hi!

I need to build a high pass crossover for my mid-range and tweeter. (vintage University C-8M and T202).

My question is whether to use a single series capacitor for the tweeter and leave the mid-range uncrossovered; or to use the single series capacitor for the tweeter and a single series inductor for the mid-range. What difference will excluding the inductor make?

(probably: phase, peak in response at crossover point)

hi davidbosch

The first choice,difficult to be better.
The second will be better than if your drivers are at the wide band freguency have a flat respond.

thanks.

but does it make any difference in PHASE response at the crossover point with and without the coil for the mid-range?

do the two choices turn out into a 90° phase difference?

davidbosch Phase driver can change when the frequency change. it wants to use a measurement. i think the problem of your design is about break up cone. in the past i found the morduntshort ms 12(no xo for bass/midrange). but it didnot good. the transient was well but the sound had not soft davidbosch if your driver have the performance. you can try.

now i keep the links to you
