Easiest way to correct this dip?

[JCoffey]

I'm looking at a couple pairs of these for my car, and for the most part for the price, they seem to be a nice little driver. But there is a 5db dip a little past 1k going up to about 3k, and I was wondering if theres a simple crossover that can correct it and flatten it out a bit. Any ideas or suggestions?

Remove the existing (?) crossover and build a new one.

Thanks for the link, just seen the 4 inch version and wondering if it will fit in my car.

The crossover is just a cap soldered on the back from the terminals. If you are careful you could remove it and replace it with a better crossover.

thats pretty much what I was thinking, but I dont really know much of anything about x-over building. Looking at the sock response graph, would that much of a dip be really obvious when listening?

 

[Keruskerfuerst]

A 12dB/oct crossover (LP,HP) would improve the sonic quality by far.

In order to correct the dip, and build a correct value x-over, I'd need the T\S parameters for the tweeter wouldnt I?

 

[richie00boy]

Yes and you would need to acoustically measure both the tweeter and woofer. Finding the T-S parameters is easy enough, the acoustic measurements is more involved, but a lot of DIYers have done it.

That would be an ideal speaker for me. I often introduce a dip (notch) around there as my ears seem too sensitive in that range.

The price is sure right. Why not get a pair and try them? See if they need a different filter later.

 

[richie00boy]

That would be my approach too. Just get em bought and have a play

 

[JCoffey]

Well thats what I was planning on. I mean hell they're only $25 a pair!

That's the idea, you can easily afford to fry a pair so get 2 in case that happens when you remove the "crossover" they come with. These must be the newer Audax drivers that are manufactured in China, there's no way a French made Audax would sell for such a low price. This being said there's probably no difference in quality.

I'll send you are pair of these if you want them. 4 ohm, 12 db hi & lo at 2600 Hz - that would help smooth out the woofer where it starts to get ragged, and offer better protection for the tweeter than the single cap. 5.5" x 2" X 1" - I've soldered leads onto them. You'd have to mount them somewhere, but hey that's part of the fun of it.

 

[JCoffey]

That might work perfectly. PM me with how much you want for them....
