Bass blockers?

Synack · 07-08-2011, 08:53 PM

Ok so I'm on my the final stretch of my perfect setup. The last thing I need to do is get rid of the NASTY distortion coming from my component tweeters. I have Polk DB6501 components. Going through the actual crossover it seems to have made the tweeters higher and louder but they still receive a lot of unwanted bass.

I have a bazooka tube in the back that gives me my bass but I have to crank up the bass on the headunit so it'll give the sub and my 6.5" speakers some more bass. If I were to completely eliminate my tweeters then I would have the perfect amount of bass at the current settings I have my system at but the tweeters just keep receiving bass and I can't figure out how to nearly completely eliminate all bass going to them.

I even went to Radio Shack to buy and install a 4.7uF capacitor on each tweeter on TOP of the crossover for each tweeter. I'm still getting a lot of unwanted bass. Any suggestions?

check if there is a DB setting on the x-over for the tweeter out put, also check that your deck didn't turn on it's eq when it got powered back up.
of course make sure you hooked the speakers up to the x-over right.

Firstly, yes there is a dB setting on the crossover. -3,0,+3.
Second, what on earth do you mean by checking to see if my deck didn't turn on it's EQ when it got powered back up? I use the EQ on my deck to do everything...

some decks, when you reconnect power will default some stupid eq setting.
Try setting the x-over to -3, you shouldn't have bass from the tweeters, normally they(x-over) are built to be, around 3.5k to 4k HP for the tweeters.

I've had them at -3. I also have the Bass on the head unit set to +6 which increases the bass over the whole system, including the tweeters. The 6.5" speakers in the front can handle that perfectly and the sub as well. But the tweeters just distort like crazy and it sounds horrible.

turn the bass on the HU back to 0, and adjust the sub amp for more bass. Is the hu running the fronts, or is there an amp on them too?

90 ST · 07-08-2011, 10:57 PM

also double check the polarity on the tweeters.

It's a small sub, so I need that extra bass that the HU is pushing out (from the +6 bass level) to get what I want.

i dont know how that works but theyre both connected to their own crossovers and those are connected to the HU.

Well yeah thats all good. Its just that there is some sort of bass or something is going to the tweeters once its gets louder. Idk, maybe the tweeters are just garbage and can't handle the signal.

Sounds like you either have your woofer and tweeter wires crossed coming out of the crossovers. Or you have blown your tweeters by distorting them to much. If your thinking your getting "bass" at higher volumes and everything checkes out and you did not run the speakers threw a factory bose amp "not a good idea" and you ran new speaker wires to the crossovers and to the woofers and tweeters my call is on blown tweeters.

To add to this, I have never heard of needing additional filters if the right crossover was used.

Sounds like I need some new tweeters. Any suggestions on some that will handle bass/distortion like a champ? I know that's a ridiculous thing to ask for but have you come across anything that will do that better than my current tweeters?

To add to this, I have a NISMO so there is no Bose amp. I had the base system. So wasn't there just no amp at all?
