crossover for horns and Id oem 6.5

[gotparts90 10+ year member]

I am getting a set of full body cd2 horns and 2 sets of ID oems and am just asking what type of crossover other people may be running with this same or similar set up. any suggestions on starting points with the crossover and what slope may work best. I am supposed to get a clarion crossover Monday but will probably go with audio control later Thanks in advance.

80-1k on the mids?

1k and up on the horns?

just guessing.

actually those being cd2s you could take them lower then 1k i'd say 800 up on the horns and 80 to 800 on the mids then 80 down on the subs. if you can take the speakers 24db slope. or 32 try and see wat sounds best.

Try to run them active, no passive crossovers. For CD2 600 to 800 depending on your power. Pm if you have anymore questions. I am running horns in my car.

thats what I am doing I haven't done active in ten+ years and had my friend set it up I just maintained. I am shooting for around 35 to the horns and 90 to the Id oems each should be a nice front stage just gotta hunt me down two IDMAX 12s on a budget otherwise just 3 old 12w6 s for now

35 watts at 8 ohm right? I would go 600 up on them then.

give the mids even more. i have 200 per on my pair and they love it.

yep 35 @ 8 ohms i have used a lot of PA horns in my time but mostly RCF/mackie stuff so I want to get a feel for what horns are like in a car. Cars are so much harder to make sound good. and my amp I have for these is rated 90 so that what they get for now. I think 90 each woofer will be plenty loud for me anyway. I will try this settings a general starting point and move from there Thanks for your advice everyone.

wait i wast aware you could x/o horns that low? is it just because the tweeter is loading off the throat or just different tweeter style?

i'd imagine partly because sensitivity is high. over 100db at 1 watt. if you only put a watt or two to your regular tweeters they would also handle a lower crossover point.

it's teh driver that's in the horn that enables it to be crossover so low

Both. It's a compression driver which is different than a tweeter. Also, the friction of the horn itself loads against the driver making a lower crossover possible. But as the horn opens up it acts like a lever on the sound waves making them more efficient. With the compression drivers alone you would need a crossover around 1500-1800 in order to be safe. (depending on the driver, obviously)

There, that's my "I flunked science" explanation. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

here you go gotparts90 got this statement from Eric over at ID for you

"Well 800 is the sweet spot usually. they handle 600 just fine but can tend to get edgy and forward sounding at high volumes.

Horn and driver together determine the best LF cut off. Drivers free air resonance is around 410 hz and the flare rate of the horn is 370 with a mouth size that 1/4 size in the 500 range. Most horns need to be double the flare rate for LF cutoff with a driver that can handle that which with free air resonance at 410 they can very well. Without the horn I would suggest crossing the compression driver as a direct radiator an octave higher so 1500 Hz or so."

thanks for the info when i ran lots of PA gear 1200 was about where I would put my horns most of the time but every venue was different depending on how big and that days setup
