I would like some help figuring out which type of subwoofer I should get. I got a pretty big room. I hope the picture of the room works. The left wall is a 7,30 meters long window wall. The bottom wall is about 6 meters long. On the right side is the kitchen and kitchen table (island). Right now I have a Denon AVR-X2400. I got three Monitor Audio Radius 225 speakers by the TV and a pair of Monitor Audio Radius 45 by the sofa. I watch movies, Netflix, HBO etc., and sports. No gaming. I do listen to Spotify too. My subwoofer doesn't work anymore and I need one that fits the room. I guess it should be in the corner by the TV. Which subwoofer should I get? Preferably (but not a must) in high gloss black to fit in with the speakers. Budget is around $2.500 / £1.600 / €2.000. I can go higher if needed. Anything else I should get to upgrade the home theater system. Thank you.
