Default prefered crossover freq for scan speak 9500's

This seems to be quite a popular tweeter, i aminterested in your prefered crossover frequency for use in a small two way speaker 14L Cabinet.

The woofer is a seas 17rcy-p, i am not convinced by the sound (seems thin but vocals are great )

so, i thought that the cross over frequency may be incorrect, and maybe the tweeter needs to be attenuated, the bass may be there but to quite compared to the higher frequencies.

I do not know what the cross over is at the moment is is borrowed from a pair of Gale two ways, hence my thoughts about doing the crossover properly. or am i trying to make a silk purse from etc etc etc...

or are the seas not suitable for this aplication 9 they were recomended to me as replacemnt for the ex002!! )

2.5k 12db can be a good startig point

BTW i thnk the 9500 is too expensive for teh P17. maybe the PL18 from vifa or 8545 from SS is better suited

Thanks, for your advice, will some thing like winisd be ok for working out the component values?

also i guess that you do not want the crossover freq to be the same for the low pass as the high?

Please excuse if these are simplistic questions, i am just starting!!

I think i will start with the crossover to go with the woofers i have and look at the others on model software, what sort of response / shape are you looking for on the graphs, smooth or going for lowest frequency at the -3db point

Navim,

No, the only two that I have are p17wj and pl18wo. I am going with the 8545 next, and maybe ss9700. Then again, I would like to try vifa xt25 crossing it high with a small mid like 8640 or smaller revelator mid . So many choices ....

Navin,

I was reading midrange distortion tests data on Linkwitz page and currently thinking about trying the seas w18e midrange in place of the pl18wo in sealed cabinets. Thats my next upgrade
