I’m new to this but I’ve got some infinity kappa perfects 600 with a kappa 303s midrange. I’m using DM810 as my dsp. I like my highs to be crisp and clear. I’ve have the midrange set to 400hz to 20khz and the tweeter 3.4khz to 20khz. The factory crossover point for the 3 way components set are 400-3.4hz for midrange. The way I have it set sounds the best to me but wondering if there’s something I’m doing wrong?

There's no need to cross your midrange that high. If you want "crisp" highs let the tweeters do their thing withough the midrange interference. 2 speakers playing the same frequencies will only cause cancelation in those frequencies. It's hard enough trying to get the left and right to play nice with each other withough cancelation. now adding the same frequencies from the mids and tweeters are just going to wreak havoc in that passband.

I'd suggest that you get a mic and try some tuning with REW.

Those mids might have some rough response because of cone breakup. I don’t know much about them but it’s reasonable to think that a 3” midrange specific carbon fiber cone might be pretty ragged up high.

Playing a mid through breakup which will happen and also having a tweeter playing the same freqs will not be a nice result despite you thinking it sounds good, it will definitely sound better if tuned properly 👍🏼

if you’re reference isn’t great then a bad setup will sound good…

Im going through this right now.
For 2 years. 2 years. I've had type s tweeters crossed passive at like 8 or 10k and a set of jbl p660c midbass. A 20 dollar line output converter. And a very cheap alpine 4 channel amp. The line under type s.
And thats it. No xover on the midbass at all.
Top or bottom. If you ask me right now how it sounds....I would say pretty good. Lol

It’s very possible natural roll off and inductance with a 6” midbass makes a shallow roll off like a lpf… and with no sub you can use no hpf and it just limits output overall… a 3” driver likely won’t have the same kind of roll off

I briefly looked for that infinity models response graph or anything that could give an idea how it behaves up high but found nothing helpful. I guess it’s possible that the top end might be surprisingly smooth and well behaved but it’s probably more likely it’s rough. Giving credit to the op, maybe it’s got (the midrange) a smooth response across the spectrum and it’s not too bad. But, we will hopefully convince him or her to look a little deeper and put proper filters in place. But thinking while writing, if it had a great smooth response throughout the treble then Infinity would then market it as a fullrange id think.

My installer had no experience with tunning or DSPs for that matter. I knew that from the jump. I just needed him to do what I wanted. Told him to get the DSP rolling and to set the crossovers how ever sounded best to him. I knew I was going to spend the next year or so tunning. My midbasses were crossed from 70-3k midranges from 200 -15k tweeters 2500-20k, front sub from 30-250. That's what sounded best to him. His response was it's louder that way. Lol I have yet to let him hear how I have it now, but I will be dropping off my SQLs soon to have my box made for them. I'll let him take a listen then. The difference now from then is extreme with proper-ish crossovers and some Helix Auto tunning.

cross the mids over at 3.5k and see if it sounds better.

why does your accord look so familiar?

ill try that tonight

this is true but the kappa perfect 3.5 did not fit in my oem location so i used the 3 inch 303s and it plays alot higher and smoother bc of the silk dome. i tried using it as a full range but it was lackluster.

Accords come a dime a dozen. You can throw a rock in any direction and will likely hit one. Lol

 

[sgtm7]

20Khz on your mids?!! Those mids should be no higher than 5Khz.
