2-way with Monacor

[ziocalepino]

Good morning. I have these drivers: Monacor SP6-108 PRO mid woofer and Monacor AIRMT-85 tweeter. I would like to build a bookshelf bass reflex cabinet using them with a project similar to this of Troels Gravesen:


18W-8434G00


Can anyone help me expecially with crossover calculation?


In annex data of speakers.


Many thanks.

Try this one: 18 litres, vent 2" by 5"; flat baffle, drivers centrally positioned as in Troels project.

tweeter filter: 5R6, 5.6uF, 0.15mH, 8.2uF (3rd order electrical, padding resistor before HP)
woofer filter: 2mH, 6.8uF ( 2nd order electrical)

xo frequency about 3kHz.

Drivers are wired out of phase.
This proposal is good enough for starters, final voicing is another matter which you can decide for yourself.

Thank you. Did you use a simulation SW to calculate xover and box dimensions?

 

[Lojzek]

Yes, I did.

edit: waste not your money on expensive passive parts. Use npe capacitors, furnish inductors of scrap piece of magnet wire, if you can.

 

[ziocalepino]

Ok. Can you suggest a good SW? Free if possible

There is a lot more information covering that topic in the Software Tools forum.
