Default Easiest way to correct this dip?

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?

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?

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.
