Im currently switching out my system again and im installing the kicker RS65.2 6.5" series up front. I already my little triangle window piece modded with glass to house some clarions. The kicker tweeter are way too deep and big to fit so i wanted to know if it would be overkill to leave them there and also install the kickers with the tweeters either in my kick pannels angling up or just leave them ion the center of the speaker. Would that be too much highs. And if not, can i use the kicker crossover for both? thanks

Yeah... No, I wouldn't do that... Pick one tweeter, and use it. Tweeters are the ONE driver you don't want more than one of, close to each other... The comb filtering can be HORRENDOUS. Not to mention how WAY overly bright it'll be. The Kicker stuff isn't exactly "high fidelity", (in this reporters eyes) and they'll need all the help they can get. Placement is important, and (also in a generally accepted opinion) the sails are a VERY bad spot to install your tweeters in the firat place - too far away from the mid-bass. They need to go as close to each other as you can possibly place them.

If you are bent on using them both, you'll have to use a dedicated crossover for the second tweeter; you CAN'T use multiple drivers on a passive crossover system without drastically altering the crossover points and slopes.

what is 'comb filtering' in tweeter applications? I've heard of it in televisions.

Kenwood has a set that have a bulb in the crossover that (for a lack of better word) eats the distortion. For my money it's the MA Audio tweets, or the RE Audio tweets for excelent sound. If you've not got much dough; don't laugh but the Boss tw-17 is a super sounding tweet for $20.

1: The lightbulb, just like every other wire, increases in resistance as it heats up. This is a passive protection for the tweeter, the distortion still gets through. There is no "eating of distortion"...
2: If you think those are good sounding tweeters (any one of them), you've never heard good sounding tweeters. Ever. Overly bright, and WAAAAY peaky response... For 17 dollars each, you can have a good sounding tweeter in these... For two dollars more than your Boss suggestion, a TRULY good sounding tweeter that would WALK any of the others you listed, try this one...

While the cheap tweeter will never be considered "world class" those are far and away better products than you listed. I agree you don't have to spend incredible amounts of money, but those that you named are FAR overpriced for the quality of the sound you actually get out of them. I think you should listen to some of the other products in the Vifa line as well.

(Brutal truth time is over now... Sorry.)

Wow. Ok. Well i'm only going on what i've heard and used. I'm not very good at the technical side of some things. Although I am very receptive to the "Brutal Truth"; and take it in as knowledge gained.

However, I think that "good sounding tweeter" is entirely a matter of personal taste and my opinions are based on nothing more.

Still support the tw-17!!! posted_image

What time WAS it when I posted that last night?!? Jeez, Dave.

OK, firstly, let me apologize... That's not like me, usually. I was attempting nothing more than constructive criticism, and I was apparently VERY tired, or wized at the wife, and I was taking it out on you. posted_image

You are absolutely right, and as I have always claimed, sound is a completely suggestive thing - what sounds good to me might not necessarily sound good to you. One of the things we try to encourage here is openmindedness and helpfulness... not opinion bashing.

So, re-read that post above, and translate it however you'd like, but filter out the venom, OK? Again... my apologies.

I might also mention (hopefully in a nicer tone) that the passive light-bulb protection in tweeter circuits is a very non-audiophile method of protection. A non-linear resistance curve is introduced to the wire, and this will affect the overall output of the tweeter in non-linear ways, not good... I personally try to avoid this type of "protection" circuitry. The light-bulb IS an effective method of protection, but I just like relays, or even better, a soft-clip circuit in the amplifier.

Haemphyst; it's cool man. No worries. Didn't offend me; promise. Just shocked a little. I appreciate honesty! It's the only way to go.

I guess it's just that I work at a shop that is a retail store not directed totally at car audio. So most of my brands are mid to upper-mid line stuff. I build systems for the blue-collar mississippi boy. I've had to make decent quality stuff sound good enuff for the not-so-picky ear. But, i'm picky. See my dilema.

And i'll probably ber flogged to death here for saying this: But, I think it's not entirelly how popular or advanced the product is that makes a system sound good. I mean, I did pretty good this year in Kansas City with a car full of nothing but entry level Sony product. The guy cady-cornered to me set up his sound with a lap-top for hours and hours. Stuff I don't know how to use. He left with a handshake.

I invite debate, and hope to learn something here. I think this site is an awesome tool for people who love to do what I love to do. If I say something that requires a whiplash ; hit me with it. But your cool with me bra.
