Fostex FF225K (Drive Units)

Would the Fostex FF225K work in the Singular ?

It seems to have a very smooth top end frequency response, although the Qts is 0.16, compared with 0.26 for the FE207.

Cheers,
Chris.

Hi Chris,

It seems to have a very smooth top end frequency response, although the Qts is 0.16, compared with 0.26 for the FE207.

The FE206E is already critical (regarding bass response) when used in the Singular. The FF225K will be too much for it though, you'll need to add something else for the bass and then the size of the Singular would be a bit too big for what it brings. You could use the Singular with a low Q bass driver though with the FF225K on top as mid-high range driver but that is not the idea behind the Singular...

Ciao,

Bert

Hi Bert,

Thanks for the feedback.
I see what you mean. Checking on the FE206 datasheet shows that it also has a much lower Qts than the 207.

I'll stick to the 207.

Cheers,
Chris.
