What mids/widebands to choose

Hi,
i feel like i need to add the 3rd drive into my 2way JBL GTO 609C front doors set. I will custom install it into the A pillar, the tweeter i would probably let them in factory triangle on the door because they would be alligned but would make a custom mold also for better aiming.
The tricky part is what driver would i choose. I don't want to spend very much on these (even tho i know they are crucial drivers regarding clarity).
To keep install ok i would need 3" drivers (4" would be too big)
I have seen real budget speakers from 10USD to 60USD (a bit much for me at the moment).
What brands from the following will i be best with:
Visaton, Lavoce, Dayton Audio, Hivi, Fountek, Monacor, Tang Band and Peerless
From specs, some are even widebands.
They will be amplified (even though i've seen these requiring 15-20 W RMS most)

thanks.
