Just looking for some real world experience people have with current subwoofers available for a $400 price point. I have just under 7 cubes NET with the dimensions minus wood thickness not including bracing or port displacement, so probably closer to 6. I will be giving it 1500 RMS at 1 ohm. Box is not built, so game is on for anything. Please let me know what sub you are using, the enclosure size and tuning and results. I'm getting back into SPL after a few years and haven't kept up to date with current SPL subs.
