Question Crossover/Speaker Design Questions

Hey guys,

right now Im starting a new Project. My aim is to build a new passive Reference-Monitor. As of right now I started designing the crossover and Speaker and would love to get your opinion and Feedback.

This is how it Looks right now.
Monitore 2 Wege - Album on Imgur

For the Amp I want to use this one:

the t.amp PM40C Endstufenmodul – Musikhaus Thomann

Could that project work? I know nobody can surely say it will work, but I want to know if my concept makes sense/has potential...

The Box has a total volume of about 14 litres and I want to uild in a BR with 1,5" Diameter and 6" length. (Thats what the Woofer Descr. suggests, With that I will get a res at 50hz and that will hopefully work against the last dip at around 50Hz and clear it a bit up)

Just want to get some opinions before I start Building it. I know simulations are only approximations....

Thanks in advance Benni

Hi, it doesn't say anywhere what these drivers are and what you did with frd/zma files.
A reference monitor would probably deserve a reference amplifier and this amp of yours does not look like one. I would look for a good deal on class ab, classic 3 stage design topology.

I am awfully sorry, I still can't seem to find the info I was reffering to. Do these drivers have a name and model?

Woofer is: SB17MFC35-4

Tweeter is: SB Acoustics SB26STAC-C000-4 1"

I can also send the link privat with the crossover

For the FRD and ZMA Files I needed to pull them with FPGraphTracer.

Then I started (like in the Picture) to work with them and try to design a simple crossover with a good freqeuncy Response.

Really appreciate your Input!


Would be great!

Maybe you can also simulate my Crossover and see if it works?

Would be a huge help!

Would love to know if my concept might work and If it could then I will immediately start building it!

Thank you Benni

Yes, that was the general idea, otherwise it would not have made any sense. These drivers are as if I have picked these out myself, not too expensive yet with great potential, great enough to be called reference ones, IMO.

There is an obvious error with tweeter zma of the raw driver from your XSim snapshot. Correct the tracing to look like a 4 ohm unit by entering the top value on y-axis as 16 ohm, not 160 ohm.
