Default tweeter problems

im new to tweets but i got a tw47 with frequency response at 2khz - 25khz

i went to pnr and they sold me a 4.7 mfd 100wv stinger crossover capacitor

but it seems as if its letting mid frequencies in. to much voice...

IDK im not sure but it seems like theres something wrong because its supposed to handle 250 rms and im pushing 200 bridged to it but it sounds like its getting over powered because of the mids getting through.

if someone can lmk where to get the "correct" capacitor for it that would be great thanks

tweeters with 250 RMS!? are you trying to break your windows? Or just your eardrums? That sounds like an awful idea.


Why not get an active?


Tweeters should be handling somewhere around everything above 4 Kh, but this is subjective to people's tastes.

I don't like to have my tweeters play much below 4k, I let my midrange driver woofers do that.

I still say get an active crossover just for everything.

It sounds like you have the right cap, you're just overpowering it. What kind of amp is it? And remember a cap is only a 6 db slope crossover, so frequencies quite a bit below the crossover point may still be slightly audible. If the amp has a high-pass x-over in it you should be using that.
Also keep in mind you're not working with a high-quality product here - the results are only going to get so good before you've hit the limits of what it can do.

+1

and if you wire more than one tweet in series or parrell, after the cap the cross over fq changes, they are rated at 4 ohms

Yeah those tweets you brought in WILL NOT handle anything like 250 rms. I dont care what they say on them. Ive got tweets that are around the same size and i am putting around 75 rms and that is plenty. The problem probably lies in the tuning. But bring it up to the shop and ill check it out for ya.

my speakers and subs can handle the volume up to 65 on my stereo fine.
thats about as far as I will go up.
but after 55 volume the tweet mixes the Freq.

im going to drop the bridge and run 100 to it later today, ill let you guys know how that goes.

ALSO, im planning on getting an active X-OVER, how about a
Kicker Impulse X3i 3-Way Active Electronic Crossover?

It costs 30 dollars used in good condition, is it worth it?
