OK, just looking for car audio stuff in my catalog from
www.parts-express.com & looking at the 4 ohm stuff. (I need a pair of front door round speakers for my wife's 300).
Pyle has a 4x10 oval Triaxial. Part# 267-731. $33.99 for a pair. *This is the only 4x10 listed in their line - at least in their paper catalog.
OK - just went online - they have 4 to choose from:

That being said, they might need to be small profile & these more modern speakers might be too large on the back side to fit. They have much larger magnets than the old OE speakers.
