These drivers were used in Chuck's "Jessie Girl" mini speaker. AP are very well thought out and executed drivers, and I have no doubt Chuck's implementation was excellent.
Woofers feature an aluminum cone, phase plug, cast frame, and model well for a 4" driver. The tweeters are just great, I tore one down at one point - lots of copper, chamfered pole piece hole, extended pole piece, even a chamber of sorts, ferrofluid. Note: this was a destructive teardown, I could not see any way to take it apart with the goal of re-assembly. In my testing, it looked doable at 3500Hz.
Two midbass, three tweeters shipped to the 48 for $50. These are pretty high performing drivers, and Chuck's design skills are top notch. Great little speakers.

He may even share his measurement files if a guy wants to take a crack at building his own crossover. Otherwise, you can trust Chuck's work.
