FI Q wich size?

[ron82nd 0]

I have 1.0 cubic feet before displacement and it is a sealed box. I am wondering will I be able to get a 12" in there with adding polyfill and make it sound good or should I stick with the 10". I will have a sundown sae1000d powering either one.

The 12 should be fine in sealed. Fi recommends .8-1.5, so you should be around .88 or so and on the low end of the spectrum, but it'll play fine. The only difference is how low it will be able to play. It can play lower with a larger box volume. Polyfill will likely help.

Yeah I am worried of how much of the lows I will miss. I am trying to get 1.0 before displacment wich would help before the polyfill is added. Do you think the 10 would play better with a .9 cubic feet box or the 12?
