does anyone know if the 10" IDMAX is out yet?

also, heres an idea ive been thinking about.

right now i have a 12" IDQ in a ported box. the bass is great, no problems with that.

but ID is coming out with a 8" sub soon. how will the setup with a 8" sub under the seats sound compared to the 12" i have now.

i know this is a vague question....
