I'm expanding my research here so i can get the pros and cons of different equipment.

In an earlier thread, Dave Brooks and other suggested i use HLCDs with 4Kw of bass so i don't drown out the stock tweeters that wouldnt be there by that time anyway.

Anyway, i came across another gadget, a Horn Loaded tweeter with specs as good, if not Better than Image Dynamics HLCDs. These tweeters cost a little less, but i have questions on the technology in general, not really the product itself.

Here is info -

I tried to find some research on them and i found a little but do not know if it pertains to these type of tweeters.

Are these type of tweeters solely dependent on the direction they are faced? Meaning, they do not cover a wide range, just a narrow range, whatever is in it's playing path?

Even if that's true, what affect would it have if i had them facing me but from the same distance as the subwoofers were from my head? The only place i'd have room for them is right above the back seat.

That wouldnt cause music to sound.... very "off" would it?

Never used em before...

And if that didnt work, what about these-

Those are 1" HLTs so they might be able to fit in my factory tweeter location. If they can mount-wise, they can handle some power!

Those..are what the fine gentleman in the dirty south call 'louds'

They are just that..loud

Hey there Shizz...I found this link that explains all sorts of different tweeters including the horn loaded designs...hope it helps.

well, i hope so for that high of efficiency.

Again, i'd like to make it known to those who didnt remember this little topic about what i needed in terms of mids and highs with 4KW of bass is that - i'm not competing in SPL or SQ, this is just for daily so LSQ or whatever it's called nowadays.

I just never had tweeters behind me before and am worried if it's gonna make it sound as if all, or the majority of my music is all behind me...

This is in a hatch so that is a plus.

I can't believe you just compared those to the Horns. No where close. At all.

this is just for daily so LSQ or whatever it's called nowadays.

Just being loud?

I don't think you'll really notice the massive problems they're going to cause in terms of a coherent sound stage or anything like that.

well thats what i'm saying. IF it will sound REAL "off", then i won't even consider it.

But, like u say, if it will make the stage terrible, then what are they suppose to be used for?

They are used by idiots currently most living in Florida or Texas that have no idea what music is supposed to sound like. They do one thing, and one thing only: they make yours ears bleed. Really friggin' loud and absolutely terrible response. Not the most complex eq in the world can give them any semblance of decent sound.

well, anything can be attenuated so i do not really understand the general statement of they are loud?

If HLTs are overriding anything, they can be attenuated...

So, if they are, what is the problem? Do they resonate? Do they distort?

Think of them as SPL only drivers.. except for your highend. One note wonders my friend.

So what you are saying is....

Even though they have a frequency response from 3.5khz - 20khz, there's going to be that very narrow range of frequencies that when played back are extremely louder than the rest of the playable frequency range? Is that correct?

One big huge peaks and a ton of harmonics. If you look up smooth response in some textbook, these will be the opposite.

If you had a 300 band eq you might after years of tweaking get them to be loud and not sound like garbage, but I really doubt it.

Oops, probably more than one obnoxious peak, but either way you get the point. Classic statement of garbage in garbage out. Those are only meant to do one thing and one thing only, make a hell of a loud noise at whatever cost necessayr.
