For science, I also bought 2 each of these to test in the factory midrange location in the dash, and 1 of them is an 8ohm driver like factory - If I don't like the fitment I will return them (but if I do like the fitment I will quickly do a splice to see how they sound before deciding whether to keep the Memphis Units) - Just looking to give people options!
The Tang Band ones with the aluminum cone were purchased(small pic below) along with these 8 ohm drivers from Fountek - Prop I'm sorry to be derailing your thread but keeping all recent speaker upgrade info prevalent in one thread is helpful for the future I think - you can slap me if you want tho.
Link to Fountek 8ohm Drivers, if these work out "the best" in regards to fitment and sound, then they would be a good alternative to the Memphis units as they are priced similarly - (82.3 db efficiency, 15w rms / 30w peak, 8 ohm)

Tang Band (10W rms / 20w peak, 87 db efficiency, 4 ohm) -

Alternatively if anyone wants a pair or both pairs after I decide which ones I'm keeping, I'll cover shipping - as I'll eat it if I end up not liking either of them and keeping the Memphis units -
