If you had enough power say 350-400 per side would you run 8 ohm mids? I have the power to play with and I'm looking at the Morel CAW series. Is there a problem besides cutting power in half?
Comments?

Most of the "mids" that I like are 8 ohms. That amount of power is already way overkill so go for it if that's what you want to do.

So whats a good efficient number for a driver? My problem is depth, can't do over 2.75" or 67mm. I also see that certain perameters such as FS and Qts? have to be low for use in a door, what are good numbers for IB installation? Been looking at these to drivers within my price range,

Personally, I am really not a fan of Morel's midbass drivers. Those that I have seen tested have had high distortion compared to competitors - see Zaph|Audio. Not to say that they don't have fans. They do. But I'm not one of them. Not to say that they sound awful, either, because I have heard Morel setups that did actually sound okay. But I'm not going to buy something with measurably higher distortion... period. They may well have other drivers that would test to have lower distortion, but I don't know. If you know of that to be the case or if you don't care for whatever reason then feel free to choose the Morel driver.

Are you specifically looking for 6" diameter drivers?
