I can't wait to read how this sounds!!//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Mid in the door?
Large format tweeter like the Peerless HDS in the kick, if you want a tweeter to play midrange freqs.

A small format crossed at 2khz with a 12dB slope still plays 1k almost half as loud.

Also, get a real HU like an Eclipse. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

half as loud as?

2k

10 dB seems half as loud. Being 12 dB down at 1k, it's ball park i guess. Point is, the tweeter is still working down an octave with a second order roll off. Cut steeper, than it's not an issue i guess.

As many times as I've tried the Prestige aluminum down around there, I never liked it below 3.15khz or so. I'd rather have that on the MR, instead. But that's just me, carry on........ //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

gotcha. i cant seem to stand my Seas neos when crossed low either. i tried them at 2.5k/12, 2.5k/24, 3.15/12, and 3.15/24, and i prefer 4k/12 over them all.

its just that the MLI is flat till around 2.5k. i mean i had mine up to 3400 with a 12db slope and it had a decent mid range, but what can one expect in mid range when its also playing down to 60 as the MLI can with authority. i never heard the seas tweeter as i prefer silk, so i can see why people dont like them at lower x/o points. it all depends if you like the mli up that high really.

3.15Khz with an 18-24dB slope will work, but you should also try them at 4k. I just did an install with AA poly and Seas Neo's and it sounded VERY good.

Also don't be power crazy with the tweeters, especially if you cross them low.

I have them at 3.2khz

I don't think you're gonna like it with the Mach5 playing that high.

he could under lap them. keep the tweets at 3.2 and run the mids at 2.5. i have a bigger gap than that and mine sounds right.

ehh... i suppose, but having a gap in your audio spectrum isn't exactly a good thing. At least to me anyway.

unless you're talking under 20hz and above 20khz //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

an under lap doesn't mean there is a gap or dip in frequency response in that area.

here is some proof:

the mids are crossed at 2.5k, and the tweets are crossed at 3.15k. also i have an underlap between my sub and mids too and there isn't a dip in frequency response there either.

Tis true. Gotta remember a xover slope is NOT a brick wall. I run underlapped also; mids LPF 2.5 @ 12dB and tweeters HPF 3.15 @ 18dB and it sounds/blends very well. I've even tried the tweets at 4k and it sounded good...

yup, i have my mids at 2.5k/12db and the tweets at 4k/12db at the moment. i'm sure the rta will show a very minor dip in the middle but thats what sounds best to me.

It's just the type of setups I like. K.I.S.S setups for everyday are the shit.
