I recently bought a pair of B&W P7 Wireless headphones, and like them a lot. They have a very warm and pleasant sound. Naturally I wanted something similar from my speaker, so I experimented with house curves and found something I like.
A house curve like this is also something to try if you feel like the room correction guide gives a little to flat and “boring” sound. For example, if the room correction reduces your sound in the 100 hz area, acoustic guitars will sound less warm and more clinical.
Remember to set LF and HF slopes to zero at step 11 so you generate a pure flat response, and then you can apply the house curve like below in Roon.
This is probably not for the audio-purists though
