Frequency for Focal ES165 KX2

Where are the drivers mounted? Keep the tweeters within 15 degrees on axis. They aren't off axis drivers..

Do you have any data to back this up?

The focals will play down nicely to 1500 the natural slope will enhance the higher xover level and by 1200 you will have a much higher slope.

Listening to them and understanding done design and dispertion.

No the phase is identical between 36 and 18. Same for 12 and 24.

do you want a big dip in the crossover or to play flat? Don't answer that

Lol at 1500 they will be smoking. That's hard for a wide band tweeter. Hell mine start stressing at 1800

The tech specs and FR graphs are at the bottom money.

Like you said to me it is real strong above 2 case of Crossing it that low won't hurt and the Tweeter is actually pretty strong around 1500 to 2000 so Crossing it at 2500 will complement the natural slope below 1500 of course this is going to limit your output but the reason you bought these drivers is not for output

For a 2 way you ideally want a tweeter to cover down low enough to keep the mid range from beaming. They can't do it. A lot of that Focal brightness isn't so much the tweeter. It's the big spike in the mid from playing higher then it should. A 6.5 should be cut off under 2000hz if all possible.

Oh. Well I have 4" midrange speakers with 6.5" midbass speakers so I guess I don't have that issue.

I'm not sure i would want to play a tweeter below 3k regardless. Seems like it would distort like crazy with any significant power to it and would likely blow regardless of the manufacturer.

How about using data. They look pretty good at 30 degrees. Nice smooth roll off. On axis will need a lot of cuts. And with a FS of 1500 they WILL NOT play well under 3k

My 1.25 silks are crossed at 2500 with a 12db octave slop. Mids are crossed at 1.6 12db octave slope. Fr is fine. Oh wait the chamber isn't big enough. Kmsl.

The one you started this thread about is a 2 way. If you have a 3 way it's more complicated.

The Focals are 1in. 1.25 can play lower.

Dude above 16k your hearing isn't sensitive. Get your rta and play 90db at 4k and 9k and 18k.

Ever look at good curves? Don't forget. The higher the frequency the more reflections. Those reflections compound.

Show me your rta. Ill make my system match your curve.

I use the Harmon curve. You will need a real RTA to match it. Not a phone app. And you will also need independent EQ which I don't think you have.

Btw op you should have a RTA. That helix has power. To use it right you have to measure. That will also help assign crossover points. I can link a video series to guide you.

Still no rta. Still no proof of anything. Not even a video.

Thats being said op. Try a few of the duscussed slopes and frequencies.

I used a AC unit. And REW. I don't need a pic. Its the Harmon curve. I'm sure you can google it. I used it with the Bit 1 and it's the base tune for the MS-8.
