2way | Tweeter +Woofer,8inch

[nareshn]

If Dayton reference series RS28A or F and RS225-8 are used in 2way config.
For a passive crossover is it possible to use just one resistor and capacitor for tweeter and no crossover components for woofer like the seas A26 . Would this work for the daytons.

Thanks.

Short answer is no. The A26 does the trick with a large inductance built in.

Thanks .

Just to clarify So the "external" passive inductance needed is build "into the speaker/woofer itself" .Then does it mean ifi look at driver specs it would show up somewhere in TS parameters?

That XO filters are somehow bad is a myth.

It is Le. But you can't use the Le value of a driver and use an equivalent coil on another driver.
What you need to look is the FR graph, see how different are the A26 and the RS225 ones.

Thank You.
I would read up AllenB XO notes in this forum and revert http://www.diyaudio.com/forums/mult...designing-crossovers-without-measurement.html

Mark Krawiec had those drivers in a 2 way.

Thank you for the response. I tried on the net .Looks like Mark's websites are not working

In 2011, Mark designed a crossover for the RS28F and RS225-8, deriving it from his original design (referenced by Wolf Teeth) that used the shielded version of the RS225 and RS28A. I designed the enclosure, a floor-standing ML-TL, calling it the RS duet. Neither Mark's original crossover nor the one for the RS duet is anywhere near as simple as you inquired about because a very high roll-off rate is necessary, with my crossover using 13 components. If you're interested is receiving my write-up, send me a private email and include your direct email address. BTW, my RS duets took 1st place in the 2012 Parts Express MWAF in the Dayton driver category.

Paul.Thanks a lot for the guidance. Also viewed youtube video where you describe the RS Duet. Congrads.
13 components per XO would be complex at this time for me to build
So iam back to the drawing board.
Maybe other options are to go the
a)active XO way or to
b)consider Seas A26 or equivalent
Any other guidance is appreciated.
