[QUOTE="Doxquzme, post: 8854739, member: 689267"] Well, this is going to be easy. That woofer [I]is[/I] surprising given the cost and build. That said, it is not a good sub in a ported box, at all. The EBP is 35 and the Qts is 0.54, this is designed specifically for a sealed enclosure, 1 cubic foot enclosure to boot. If you want to take advantage of its high efficiency and very low Fs of 20.5Hz, stick it in a 1 cubic foot box stuffed with a pound of polyfil, that’s the best case scenario. I went ahead and modeled the woofer in your box with BASS Box Pro and there are some serious issues. The response curve looks more like Mrs. Toads wild ride – wobbly and peaky. The cone reaches maximum effectiveness at around 100 watts then the power loss (cone displacement) becomes a serious issue. That alone is a reason not to run this woofer in a ported box. You are throwing away valuable sound (volume) at anything over 100 watts, not good. Add just 25 watts to that and it starts to lose it for anything under 60Hz, effectively diluting its performance for anything below that threshold. So, the cheap option, seal off the port and stuff a .5 cubic foot block inside and stuff the remaining airspace with a pound of polyfill and you be able to give it the full 300 watts and have a much better sounding subwoofer than you currently have. That box is clsoser to a ported box for a 10" not a 12". If you don't want to seal it up, this would be another option. It's a drop in for your box and models very well in your box.
