Inputs wanted: 2nd order crossover design

[REIER]

So I'm about to dip my toe in to crossovers, and would really appreciate some inputs on current crossover design.

Setup as follows:
- Low : 2x TB w5-1138smf
- mid: dayton rs125-4
- High: Peerless DA25tx00-08
- amplification: Arylic Up2stream Amp 2.1


- horizontal soundbar-configuration
- vented sub section
- Crossed sub/mid @ approx 120 hz
- Dsp for correction

Thought is to use as few components in crossover as possible and correct notches with integrated dsp.

Power dissipation of the resistor is within limits according to x-sim.

Will 2nd order crossover work with this tweeter crossed @ 1250 hz as suggested? Thoughts and inputs much appreciated

sincerely

Did you look at any of your component values or your impedence plot?

 

[REIER]

Well, I am not too much of an efficient cross-over designer at this stage, please tell me what is off? =)

Updated suggestion:

Try putting the resistors beside the tweeter.

 

[REIER]

Yes, lets try this. what do you think?

Your tweeter is down 10 dB at 1000 Hz. Is that enough attenuation? I have never worked with this tweeter before, but it seems to me the crossover frequency is too low.

 

[cowanaudio]

A bunch of that is probably tweeter acoustic roll off.

This Peerless tweeter is down about 3dB at 1KHz on an IEC baffle as shown by the manufactures data sheet. A narrower baffle will lose another dB or two, so electrical rolloff to get that acoustic response would be about five dB down at 1KHz. I doubt that tweeter can play particularly loud at 1KHz. I agree the crossover frequency and/or slope is too low.

I think i might be following. Do you have any idea how horizontal soundbar configuration will affect bs? If I follow correctly, your assumption is that the tweeter will not be able to play loud at a 1khz bcs of max excursion capabilities? Even if the amp is not rated for more than 50wpc?

Thanks for all the answers guys, really appreciate it
