OT: Home HiFi Subwoofer

Cheers! I would like to think about my Christmas present so slowly, and this is supposed to be a powerful subwoofer for my room. So Home HiFi. So far I have a stereo Yamaha RX-E200 with two NX-E200 2-way boxes. And now I want to amplify this with a subwoofer in the bass area. The stereo has a sub-out, on which I want to connect the Woofer (or the Woofer Amp) and possibly cut off a little deeper, because the sub-out for my taste is a bit too high, I guess at about 300-400 Hz. 100-200 Hz with >10db/octave would be nicer. The sub should not make an infinite level, because I can not turn up so loud anyway. But it should not start to distort already at a bit more dB. So: volume but not at the expense of the sound. That is more important to me anyway, I would like to make the Woofer above all the lower octaves between about 15 and 80 Hz audible and above all noticeable. Music is a bit mixed, but mainly la Narrower, deeper bass, like U2, Phil Collins, Depeche Mode. Have already looked around a bit and have considered the Visaton SUB W-20.39. That would be very acceptable with 80 euros. I would of course need another amp, I would like to do the Woofer active. If someone has already had experience with the Woofer, would it meet my requirements? Price should not be more than 200 euros for Sub and Amp. So, even every as long posting is at some point to end e, Thanks for reading and thanks for your answers!! merendo
