need help xover and polarity of driver

[hyl2369]

any opinion any suggestion any idea
thanks for you reply.

should I reverse the tweeter's polarity??
Xover idea from http://home1.stofanet.dk/troels.grav...5CY001_OWI.htm
because w14cy001 almost the same with w15cy001 isn't it??
why in audio clone the tweeter is not reverse??

this is question
ow1 (87db)or ow2 (90db)
the ??ohm resistor

If you've decided on the crossover, just listen and see which sounds right.

I would do a spice simulation to see how it turns out.

the seas excel driver seems need LC circle to reduce magnasium cone's break at 9K see this http://www.seas.no/excel_line/excel/e008.pdf
at 6K~14K bad in response so I use 0.12mh 3 uF paper-design
but I don't have measurement to test also don't trust my ear...

I have hear about 8513(90db) can be replaced by ow2( because 90db so not ow1 87db) without changing xover
But ow1 is more suitable used in two way bookshelf,really??
so if I use ow1 the "audio clone proac one sc" Resistor-value should change to <5.6ohm?? is 4.6ohm ok??

other question performance between ow3>ow2>ow1 in what condition has differance result??

ow1
for monitor impendece response better than>ow2

ow2
90db>ow1(87db)
off axis>ow1 (from LSDG)

ow3
good looking (gold version but ow1 ow2 also have)
F-S?? (ow1 ow2 also have FS version)

You probably want to check your low end zobel first, it seems quite high in frequency, is that what the box does to the woofer?

Could you post the graphs for OW1 and OW2?

"low end zobel" ?? my guess value from the two xover in order to reduce the w14cy001 800~~1.2K rising db , I don't know that is right or not?

can you tell me some free soft ware for simulater xover response?

Looking at the graphs, it seems like either resistor value would work untill you find the results unpleasing or your own measurement shows differently.

The RCL circuit really seems like quite a deep notch for the hump you are talking about. I wouldn't worry about the hump until the test or listening.

If you haven't modeled the impedance in SPICE, it would be a good idea to do so. It's quicker to look at curves and adjust than to look at the time constants and Q to figure things out. Sorry if I seem a bit slow.
