Help me with a crossover.

raypalmer · 4th April 2009, 10:04 PM

So my speakers:

BR cab tuned to 46Hz. With this woofer and this tweeter need a crossover at 3KHz. What's my best crossover?

Right now I'm looking at a 3rd order Bessel but I am not very knowledgable about such things so.... is a 3rd order okay? What function? Should I go 4th order?

Same woofer, but different tweeter

Easiest would be to buy the Hivi tweeter as well, as its very cheap

Or else it would be trial and error

Maybe try 6db with RC fore bass and 12db fore tweeter(reversed pol)
Dont expect calculated values to work properly

High xo point wont work with that woofer, as it peaks early
And with lower xo point one should be very carefull with the tweeter

May very well be that 18db around 2.5khz would be ok with these, and might work with some fiddling, cant say really....you are the only one that can have a listen to the result

Tintius my Deutsche isn't what it should be.... is there a crossover schematic for my woofer with the aforementioned HiVi tweeter in there somewhere??

Or is that Danish? Swedish? help

raypalmer! your woofer is difficult to design XO. because it begins to peak around 3.3 kz. the tweeter does not has the problem. mmmh.....the final but is not countdown. i think the XO at 2 khz with roll off 12 db at all. it can use.
