Well i've never had an active setup and im in the process of finishing up the install on mine now.

Does anyone have any recommended crossover points/slopes for my setup so I have a starting point at least?

Equipment:
Pioneer 800prs
Image Dynamics OEM 6.5" mids (in deadened door panel)
Seas Neo Textiles (in a-pillar)

Let me know if you have any ideas on where to start!

I'll say 3.2kHz on the tweets, 18bd/oct

ID mids Mid Lo 63Hz, 18db/oct, Mid High 2.5kHz, 18db/oct

I've personally ran a set of the ID OEM mids active for 2 months, and I ended up liking them best set at 80Hz mid-lo and 2.5kHz mid-hi, 12db/oct slopes for both. Those are great mids and can take some power......especially after a couple weeks of break-in time.

Not trying to high jack ur post :) but, i'm in the process of going active as well....and looking for as many suggestions on this same topic as possible!!!!

my speakers:

focal polykevlar 136k (old school)
http://www.woofersetc.com/index.cfm?fuseaction=product.display&product_id=1157
peerless sls 8's


On the Focal's......the passives are high-passed at 3.5kHz (18 dB/oct.) so, this mean i can take the mid-woofer up to 3.5kHz and the tweeter will handle everything else above that....Right? also, can someone suggest a tweeter that will match up with this woofer?

thanks

its all good, but you did highjack it just by making that post.

Is it normally ok to have crossover points with some space in between? Also, should I go as low as 50hz on the sub since it's only 1 10"?

1.small gap is good.

2. 50hz is fine with a 10.(but try 60 -70 and 40 and 100 and see what you like best.50s a starting point.i like 60.)

So far we've got:

Tweets: HPF 3.2khz 18db/oct
Mids: HPF 63hz 18db/oct.......LPF 2.5khz 18db/oct
Sub: LPF 50-100hz

What kind of slope do most of you guys run on your sub(s)?

depends on the sub. mine is at 63hz/18db.

I know 60 already answered, but just for future reference (maybe for a search) the gap is referred to underlap. To the contrary, using two drivers playing the same frequency is called overlap.

1.small gap is good.

That must be why they call you "60ndown" :D

I think 18db/oct would be perfect for that ID. Might want to try 12db/oct as well for fun. I think you have some pretty good starting points, but remember tuning is going to be a process, so play around and fine what sounds best to you.

thanks!

Yeah I was really just needing some good starting points since this will be my first time tuning and active setup. I believe I have a very good ear for tuning, or at least considered the best by my friends who come to me for tuning when they want it done, so once I get the starting points established I should easily be able to play around and go from there.

happy tuning :)

with polarity on all 5 speakers reversed i have my sub at 50 24db, mids at 80-2500 with 12db on both ends, and tweets at 4khz 12db. note that it's a good idea to keep the same order on both ends of a bandpass to avoid phase issues.

so i shouldn't have my mids crossed at 80hz/18db, - 2.5khz/24db?

i would only think it matter where two drivers would meet. for example i wouldn't think you would want to cross a mid at 2500hz/12db then cross the tweeter at 2.5k/18db. different slopes where two drivers would "intersect" i could see possibly being a bad idea.

i would think that at different ends of the bandpass it wouldn't matter. but i wouldn't know, i'm not expert.

going from a 12 to a 24db slope flips the phase 180*. that's the same thing as reversing the polarity at the amp. the day i realized that keeping the same order slope on both ends was superior to any type of mixing on them was the day i quit messing with my crossover on a daily basis. i also don't believe in odd-order slopes such as 6 and 18db. i have been proved wrong on the odd-order rule i have though but those cases are rare.

ok, i just don't understand why it would matter. like i was saying i could see it being a problem if you used a 12db and an 18db where two drivers would "intersect". but not using different slopes that are many octaves apart where two drivers aren't trying to blend. i just don't see why it would matter at opposite ends of a bandpass.
