Matching woofer/tweeter, does this reasoning make sense?

[deadlinguo]

Hi everyone,

I'm looking to match a Dayton RS225 8" woofer with a tweeter for a two-way system. I'm new at this and want to see if you guys think my reasoning makes sense. Keep in mind this is a newbie project.

Dayton RS225-4 8": http://www.parts-express.com/pe/show...number=295-376

So far I think this is the best match for me:
Tang Band 25-1166SJ: Tang Band 25-1166SJ 1" Neodymium Tweeter

Crossed over at 2000 2nd-order using this: Dayton Audio XO2W-2K 2-Way Crossover 2,000 Hz

I have 90x2 watts RMS @ 4 ohm from my amp.

I picked the TB tweeter because:
It runs at 4 ohms, I don't have a lot of power to work with so I tried to avoid 8 ohm tweets.
The sensitivity is pretty close to the woofer, I'm going for simplicity and hope I can just drop the woofers/tweeters together with the crossover without any need for further adjustments.
I plan to mount the tweeter braxially on the woofer to avoid annoying imaging problems.
The woofer's upper range ends at 2000, the tweeter's lower range begins at 2000. Although this isn't ideal, from the reviews I've read it seems like both components can handle these ranges competently. The frequency charts also seem to reflect this, but I'm too inexperienced to know how to properly read the charts.

Finally, this is all going into a car. Weatherproofing shouldn't be an issue. I don't plan to Dynamat unless I get rattling.

Thanks in advance for any advice.

Going lower impedance simply makes the amplifier produce more current, it doesn't really translate into making it take less power to drive, especially if you have a lower powered amplifier as you've said is your reason, it actually makes it more difficult to drive.

Edit: Those pre-made crossovers are usually terrible as well, especially with metal cone drivers that will have strong breakup that need a little taming, my bet is those drivers with that crossover will sound really screechy in the upper midrange.

You missed the basics
Like that a crossover network works on a specified target .
On the P.E. description is clearly written ( but just reading through the threads you should have guessed ...)
The high pass crossover frequency is rated for an 8 ohm load

Remedy (theorical ) : double the capacitor value and half the inductance
