Ok, so I currently have the sub on the right with the red pole piece:
Just bought the one on the left. They have different impedance coils, so I'll have to re-cone them.
I have a few different options. I can leave them as 12's and have plenty of box volume and port area, or i can make them as 15's and be kind of pushing it as far as box volume. I'm not sure exactly how much room I have. It's a weird space, but I could measure later.
My question is: How do you make subs perform better in smaller ported boxes and not need more box volume? I know Sundown subs are fine in smaller boxes. @Sundownz; can you explain?
I was thinking really loose spiders, but I will be running a lot of power.
I will be running them on the T 20.2
I'm thinking about .7 nominal, so should I do .7 coils or 2.8 coils? I have heard that wiring in parallel yields higher SPL than wiring in series, even when the same impedance is reached.
@Jeffhulbert50; any input? Could you build them?
I will have both 12" & 15" baskets and a pair of both 12" & 15" Composite cones.
