Hi guys,

I'm trying to design my first speaker, a simple two way with a 7 inch illuminator woofer and the 6600 illuminator tweeter, the box is ~ 35L. I was wondering if a crossover like this seems reasonable because, well I suck and have no idea about crossovers, just being playing around trying to keep it as simple as possible. I've traced the SPL and impedance with SPL trace, that's probably about the only thing i've probably done right...
Thanks
A

Without doing any calculations, this xover looks like something that could work. Just a word of advice: buy a measuring mike to verify your work. The Behringer is quite good and affordable, it probably costs less than what you will spend on glue and finishing. You will need it not just to see if your xover functions properly, but also to search for standing waves in your enclosure and, if you do a bass reflex, to get the tuning right.

Success with this project, you certainly started out with some fine drivers!

Thanks for the advice, sounds like a good investment. I will in fact be using a vent tuning the woofer to about 32hz.

Quite expensive for such a low sensitivity? Resonant freq 41 Hz if you look at the impedance chart. Tweeter sensitivity very much higher, for me a bit of a miss match. Being old school I would never consider mixing 4 and 8 ohm speakers.

Hi balerit, thanks for the response. It's actually 10uf, the software just converts it into a floating point number. You're right, the woofer is 8ohm and the tweeter 4ohm. I seem to see a lot of projects online doing the same kind of thing, (Illuminator-Monitor same woofer different tweeter), I assumed it was ok to do so?

woofer: Europe Audio

tweeter: Europe Audio
