Two way crossover with no capacitors
 
1 Attachment(s)
Hi

I have made a crossover with 2 inductors and 1 resistor.
Using Scanspeak 6600 and Seas Excel 6.5".
It sounds realy great, the tweeter is so smood.
I know the Excel have a peak at around 5k Hz but this is no problem in my ears. What do you people think of the filter?

The 0.12uH is 12 awg and the 1.8uH is 16 awg.

inefficient, the resistor is wasting power

This is like ar-sxo right?

not a good idea IMO

Have used it earlier with great results myself.. (ss9800 and 15w8530k00)....
That resistor is burnin some power yes...
Using parallell XO with my speakers today..

Horrible idea when the best of inductors is at least 20dB less linear than the worst of capacitors.

Another version of that is the xo design employed years ago by Sonus Faber in their highly regarded and very expensive Extrema speaker.
The SFE design inspired my 'Intimates' speakers. Introducing the "INTIMATES" (high WAF & quality sound)
I solved the resistor power dissipation issue using my vent. Visit the link for details. Strangely though, efficiency ended up about 84 dB @ 2.83V - not much different than many commercial high end 2-way mini-monitors.

speakerdoctor, the SFE crossover was what inspire me, the sine-cap.
Have a friend that made a pair of replica SFE in the late 90th.
With the right tweeter and bass. They were extrem heavy driven.
Only big Mark Levinson and Dynamic Pricusion made them play at there full.
Some hade to do with the resistor(s) to the tweeter in the crossover.
Try to eliminate this with the new filter. Or am I way out? ( out biking as we say here up in the north )

You eliminate your resistor, and your amp will likely die.

Why?
I mean not for this particular example, for this idea in general, why couldn't you just use inductors in an xo?
