FT-1600 MkIII

[imagios]

Hello,
as a happy owner of a DIY MKII from Bob, I just one day looked up to exchange my 167E driver(it has a small pierce, nothing that influence the sound) and to my supprise fostex discontinued the production...
I saw there are new ones FE166En, with lower FS but higher Xmax.
According to the data I dont belive it would be working if I just put them in the MKII encloasure, am I right?

Bob's the man to ask that; he's often around here, but simplest way would be to email him directly. FWIW, they're clearly not a direct swap, but you might get away with it (might) with a few ohms series R. Otherwise, it's a case of seeing if any dealers still have some 167s on the shelf.

Right but this way every body gets the answer and Bob dont needs to answer each of them.

That's why I mentioned that he's often around here.

I don't pipe up to often, but I'll always out there!

The FE166En simply needs a smaller box than the FE167E. The main difference between the MkII cabinet and the MkIII cabinet is the depth. There is also a slight difference in the tuning and stuffing (the MkIII tunes a bit higher than the MkII). On the bright side, the FE166En has a better top end and all around sounds nicer.

But, there is no simple way to take the depth out of the MkII cabinet to optimize if for the FE166En. Unless you want to start over, I'd recommend you live with what you have.
