100-200w D clasd subwoofer module, pcb recomendation

I will like to make speakers with active bass driver till max 200hz. Upper drivers will be driven from othet high quality amplifier. I have tried some 50w Tpa amplifier and bass driving is quite good. For other spectrum i like solid state or tubess better.
Any recomendation for mono module or pcb for 100-200w D class for sub. It must have level, cut off frequency and phase regulation. Or maybe amp board and control board separately.
Thank you Davorin

TDA8950 makes an ideal choice for subwoofer duty for about 300W ... current setup ... this is mine current using for a 12inch car subwoofer driver used at home ...
