Neotera Audio 10" Ultra Flat Subwoofer- 4 ohm

Don't let the unique t/s parameters fool you. This driver belts out clean deep bass. The giant voice coil diameter reduces power compression, which is especially important in the deep bass where all drivers are inefficient. With room gain you will most likely have to reduce the deep bass with EQ instead of other subs than need boost. This results in more amplifier headroom in deep bass with the Neotera.
I have compared it to other drivers here on the Facebook DIY Loudspeaker Project Pad https://www.facebook.com/groups/DIYLoudspeakerProjecPad/permalink/2196274674061691/
