My rant about tweeters


Jessica

Recommended Posts

i had the same problem with my t1 tweets and they are silk domes. it was alright but it hurt like hell when like you said someone said the "s" or a cymbal was struck. i have all the gains on my amps set the same level but my mids are at -10dbr on my 3sixty and the highs are at -25dbr. I believe my xover is at 3500 or somewhere near there at a 24db slope. They sound great and i have them installed with some AA mayhem tweeters too and it complements the sound perfectly. When i had the tweeters running with the passive xovers it was alright because they absorbed a ton of power before it reached the tweeters but when i went all active oh man did the speakers get louder from it not losing power output.

Sometimes running your tw off the xover on an active setup can do wonders for the system. ;)

not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. :)

Are you saying, use the passive crossover for the tweeters? I may have to use the xover for the mids too. I would rather have a brick wall at 100hz than have to run at 140hz at 12db. I want to get as much low range (down to about 100hz) as i can in my mids to help with male vocals and there is some information in music between 100- 140 that gets lost.

It's those little transient things that give that little extra oomph to music. Like, in some songs the lower hollow sound an acoustic guitar makes that comes from the body of the guitar. Or some really high slap bass has some stuff that plays up there that gets lost using a 12db xover at 140 or 150. I notice that some digital music like dubstep has some stuff in that range mixed with the wizzles and wobbles that if once you know it is there you really notice when it's not.

Anyway, TLDR . I will try the passives, and see if i can clean it up some more. Then this spring i can get to work on my doors and get my midbass in.

Try just the tweeter first. leave the mid active. The xover might be just enough to tone down the tweeter to a desirable level. Also work with placement. Sometimes on or off axis makes a huge difference not only in the sound stage, but in reflection peaks and dips in the environment . I had some strong peaks when i went off axis from the reflection off the glass.

This has been a good read. And for the OP, you are right- different things sound "good" to different people. My preference has always been to have lots of treble but I hate the harshness. I can't take what a lot of people consider good sounding tweeters- they are just too harsh for me.

What kingsuv is suggesting has worked for me as well.

I will try to keep this short, but here is what I have done before and what worked for me and what my progression has been on crossovers (tweeters specifically). Run off of a passive xover from a "full" output- I don't usually like them. Too harsh. Run with a "bass blocker" or -6 db capacitor installed passively at ANY frequency I usually like a bit better- to a point, then they get fatiguing after listening for longer periods of time (not harsh though). Run with an Active crossover ONLY- with a dedicated amp only for the tweeters it sounds quite good, but can tend to become rather dry sounding. I guess that is because of higher roll-off and the crossover used. The tweeters just seem to loose something and that translates into loosing depth of the music for me. So... that leaves using a combination...

Right now I have 10 pounds of crap in a 5 pound bag to get the tweeters sounding like I like them- Active crossover on the head unit, high pass on the amp, passive crossover on the tweeters, then -6 db capacitor on the tweeter itself. Each of these crossover points are set progressively higher- ex: Head unit @50 hz, Amp @85 hz, Xover @3500 hz, capacitor @6000 (I can't remember exactly). Safer for the tweeter, and an exponentially diminishing roll-off. Passive crossover is still in there to do its work too (like has been said, they aren't just crossovers- they also have resistors and some more than that).

All that being said- I like silk domes. I just can't make myself like the sound of other dome tweeters (I have not heard a ribbon tweeter yet).

Additionally- on axis / off axis makes a big difference, as well as how the tweeter is mounted. Diffraction is EVIL. If the dome of the tweeter is too close to a hard flat surface then diffraction is caused close to the speaker- sending out all kinds of funkiness. IMO - tweeters need to be mounted so they are away from their surface (think of putting the tweeter inside of a ball) and the enclosure should be wrapped in something soft like felt, speaker cloth, etc...

Anyone recognize this one?

Well, There is a lot of good advice here, Thanks to all that have posted. I will try as much of this as it takes.

Right now they aren't exactly pointed at the windshield. They are in the corner of the front window where the side mirror mount is pointing across the car and slightly away from me. Pointing them at me seems to worsen the harshness.

They are mounted where the ones in this pic are, and pretty much this angle. (these are my polk tweeters not the fosgates. Which, actually i think may have sounded better lol :/ )

I am going to get the passive's hooked up, and i will get some double sided sticky tape and see how they sound up on the "A" pillars at various angles.

And if all else fails i will try to find some silk dome's and go from there.

yeah I hear ya bro! Sucks to fork out a isht load of cash and then it not work out. Specially in this economy...

I know what you mean about the aluminum tweet sound too, I like when the drummer hits the center part of the symbols real hard to get that TANG! TANG! TANG! sound. Cant beat metal tweeters for that. But after a while, if the tweeter isnnt matched up so well with the system or room acoustics, it becomes burdensome to hear them. Silks can give you a more overall satisfactory experience. You might lose some of that hard symbol, but you can find music more appealing in other areas. Try some quality $40-$50 silks first to see if they will work for you. Try ebay to find some used ones. Maybe you can get some polks or something for like $15 or so. That should be good enough for you to determine if thats the road you want to take, without dishing out a lot of money up front....gl

I tried a $60 pair of kicker tweeters (cheapest ones they had) they were complete crap. TISSSS TISSSS and barely got loud. My stock tweeters were cleaner/louder

My Alpine 6010ex neodymium tweeters from the early 90's have been the best sounding tweeters I ever ran.
