crossover help for my boombox

Last thing...
After listening to the box for a few days i notice that it gets distorty if that's the right word when the amp is a little over 50% volume. This may have happened before but only when the volume was 75%-100% volume.
Is it because the crossover is 6 ohms now that it may be louder but distorts quicker?
Is it because the lepai amp starts to clip at a certain range?
Is it normal for that amp?
I think the distortion is coming from the tweeters but its hard to tell at that volume.

Any experience is welcomed.
 
Yes its defiantly coming from the tweeters. One song I was listening to only came out the tweeters during a certain part and they were crackling at the 50%-75% volume. And then the song did just the woofers at the same volume and they sounded fine. what could be the problem?

Could it be that a frequency that the tweeter doesn't like is reaching it causing problems?

I ran a frequency test I found on youtube that did a test wave through 20hz-20000hz and the woofer crossed at around the 4500hz-50000hz range I can't be exact it happened to quickly and it was too loud, and then the tweeter turned on and took over, so I think the crossover is doing its job properly.

Did you change the frequency of the crossover to work with the new tweeter?
This is my interpretation from your line of work (this thread/posts).
Fs in your tweeter is at crossover frequency so that it's very bad and cause of resonance. I told you to use a simulation software with the FRD/ZMA's as a last and useful resource, if not making guess work in addressing crossover changes say from initial 2K5Hz to possible 5KHz or something similar. :eek:

Maybe it's something else, like components or connections... revise all connections and measure components if you can.

Since the tweeter and woofer are almost identical I thought the frequency was the same.

But I asked my physics teacher this morning for his opinion and he said it might be because I didn't solder anything together that the crackling might be occurring.

I only twisted the wires together, the reason I didn't solder them is because I kept having to move things until I got it right. But now that it is right should I solder them all together or will that really make the problem go away.

The reason that my teacher told me was because the connection could get oxidation and create a resonance in the high frequency range which would be in the tweeters making the crackling noise.
 
Ok, I soldered everything up and it is much better, now its only sounds crackly a little bit at 80%-90% volume which is where the speaker also starts to max out. So now i think it is the amps fault where it starts to begin clipping. But i think it is all fine now. I'll keep listening to it to make sure, but for right now i think it sounds good.
 
No, its both of them. how would I go about fixing the crossover frequency.

Also i hooked up the tweeters backwards by the way, will that make a difference. I thought the positive and negative was supposed to be reversed it the crossover picture.

please let me know. :)
