Feel free to better like the cheapest TB or Vifa, that said its a stupid message to hear about in a thread where owners of course like their own stuff and what they can tweak out of it, especially because you misunderstand that this thread use 10F/8424 and not 10F/4424 and also because it sounds like only reference for claim is using ears.
Okay I can take that it's stupid to you and to some others or majority, but not to someone who has similar taste like me.
No offense and had no intentions, I was just disappointed and saying what I had to say about my experience with that 4Ohm model that maybe differs in sound from the 8Ohm or maybe not
It's the wrong thread, should have posted in small drivers comparison, but anyway... better not lol

Yes, the crossover is 1st order on both, with a Zobel filter on 10F plus some padding. Here it is redrawn with values currently used in the above pictured XO. When used with the woofer on top and speaker on 30 in tall stand, the path difference from mid-tweet to the ear is delayed just enough to make it transient perfect.
Very similar to the crossover I'm using, inspired by this thread and your build.
Currently I'm not using the tweeter, I find myself missing just a tiny bit of hf. I'm also making new baffles, and about to upgrade a few of the crossover components as well.
It looks like the 10F/8424G has a bit more of a rising hf response, perhaps that would suit my ears better in two way configuration.

PVC is a darn good idea, is the dagger sealed, or is there a small opening at the rear?
I'm seriously considering the 10f/8424's, they're not cheap certainly, but not absurdly expensive either.
Dagger is sealed and progressively stuffed with fiberglass to be dense at the rear tip and loose near driver.
Btw, I just measured the new XO and for some strange reason, needs an additional 4.7R of padding on te 10F (in series with first 4.7R) to measure flat like the previous XO. Anyhow, it sounds even better now with more full bodied bass. Some may like the upward tilt as it sounds more lively. Only thing I can think of is that the 3W 1% metal film resistors I used before (qnty 2 x 10R in parallel) behave differently that the Dayton non-inductive cement-filled ones I am using now. I thought it was the difference between 4.7R vs 5.0R but that added 0.3R did not fix it by any means.
It looks like you have FF85WK's? Those are ok, but much lower power handling and less xmax, so will distort at higher SPLs. You can try the 10F/8414 which are only $65ea and perhaps even flatter measuring. Although, they don't have the rising response which, maybe you are looking for.
@Sharpi31: the Dunce caps are great idea! Thanks - sporting good store?

I've searched and have never been able to find a cheer horn the right size or material. Can you tell me the diameter and length and the manufacturer? Maybe I can find a source in the US. Thanks
I just did a search for sports cones.
12in high ones (this looks like a good size):
Jet.com - Prices Drop As You Shop
Set of 12 x 7in high ones:
Amazon.com : Fun Express Set of 12 Sport Training Traffic Orange Cones Soccer Cone : Sports & Outdoors
Trick is the mouth needs to be big enough to fit the driver cutout and basket/magnet. I agree that the semi-rigid vinyl is an ideal sound dampening material.

If it can help below have some same condition data for FF85WK verse 10F/8424, on distortion front in general it looks like drivers as FF85WK / SB65WBAC25-4 / TC9FD18-08 have a mostly forward 3rd harmonic dominant profile where 10F/8424 is close to be 2nd harmonic dominated.

Nice data plots there Byrtt. Was the data taken by the FF85WK from the ones I brought you when we met at Wesayso’s a little over a year ago now? What a fun night that was.
Great to know they are dominant 2nd order distortion drivers. So that means that there is an asymmetry in the suspension restoring force. Neat.

Oh o.k. I've looking at megaphones. I'll put some of those Amazon ones in my cart. Quick,easy and cheap way to swap drivers. If they don't work I could always work on my agility which I'm sure my wife would find hilarious.

Yes thanks those FF85WK curves are what you kindly brought me at that pleasant meeting
.The higher costs for 10F is general not to like but in directly comparison test under same condition it have areas where it stand out and distortion profile looks be one of them.
I bought these ones: PRECISION TRAINING 9" Traffic Cones (Set of 4): Amazon.co.uk: Sports & Outdoors
The mouth area is plenty big enough for a 3-4” driver, and the four fixing holes make for easy mounting. I filled one with water to find the 1.1L volume.
I applied some adhesive 5m closed cell foam to the front face before mounting. That made an air seal on the inside of the cabinet.
I applied adhesive foam and loose wool to the insides. I used a very sophisticated scientific method to confirm the damping properties: held them over my ears to hear how well they worked as ear defenders

Upon further review - X, the ones you linked are described as rigid and Sharpie, the ones you linked are kind of expensive over here. I found these Amazon.com : BlueDot Trading Cones (12-Pack), 9-Inch, Blue : Sports & Outdoors that look they would work well.
These look like the right thing, and nice and cheap
