You may want to give a dollar range, unless you want a bunch of $2,000 recommendations

 

Less than $200 for the pair would be ideal. They'll be playing with Alpine S-types.

 

You can check the classifieds on here, might find something new or lightly used that will work for you.

 

I'm currently installing a pair of these Infinity Perfect 300M's, but can't give an opinion about how they sound, yet.

I used the "make offer" button and got them for $170.

 

these are really quite good. heard them a couple of times and JBL Goodness all around!

 

Edit: CDT is a PITA...

 

I’ve tried quite a few 3 inch drivers and I think the unity u3 from hybrid audio would be your best bet under $200.

Cdt es-02 @ 90 or es-02a reg $250 on sale for $109. Cant go wrong with either

 

I've used Stereo Integrity M3 Carbon and Morel CCWR254. In my car the Morel has a very smooth, natural sound. M3 perhaps a little less so, but a bit more dynamic & play louder without distress. The larger M3's ability to play deeper is what won out, was easier to blend with midbass. But I could live happily with either.

 

Erin H said some nice things about these. I bought a pair but can’t find the time to toy with them. I’m thinking about going the opposite direction and doing simple two way front in my next car. Which is crazy because I have a pretty decent three way currently. Just a super budget thought.

Tectonic TEBM35C10-4 2” wideband

I couldn’t help myself lol, I’ve had these in the back of my mind for about a year now. Way smaller than I expected for a supposedly 2” driver but I’m cool with that, should help the high end. @ErinH gives his thoughts on these here...

Just to beat my suggestion to death lol

 

If we're going there, throwing the Cp-220 in for consideration.

I think it was you mentioning these a week or two ago. So many hidden gems out there hidden by the expensive stuff.

 

I have the 300ms and they’re good…

not to shill for myself, but I have a pair of Hybrid Audio L4s for sale right now if you can fit them… I dare say they’re better than the 300ms but I never did try them because I can’t measure **** right apparently.

 

The number of recommendations pointing to 2-3" drivers is encouraging, because they are going to be a lot simpler to fit on the dash and potentially have room to aim too. I found a deal on some CDT HD-3, hopefully that works out. If not, I might try one of the smaller options and cross around 500hz. If they are only rated for 10w or so, is it safe to throw 45w at them with a crossover, at least double Fs?

 

If you’re going three way, which has potential to be superior, you’re on the right track with a 2”-3” like the cdt. I’ve personally had a craving for a system of utmost simplicity for a few years now, such as a L and R wideband and front subwoofers but it’s a stretch to make so few speakers work perfectly in a car.

 

Just make sure you measure the cutout diameter for those HD-3s and don't rely on what their website says... Pretty much standard fare for CDT it seems.

 

I have the Peerless NE85W-04 in my 3-way setup, after lots of research it met all of my requirements. Sounds great to me and easy to tune and integrate. I wouldn't worry about power handling, if you set your crossovers respectfully it doesn't really matter. I have 125w going to them and they never complain. NE65W and NE95W are good too, slightly different size and Fs.
