can subwoofers make things worse?

The way room correction works is its an active EQ device that compares the incoming signal to what it hears happening in the room. This might be done with a test signal.

So at that point if there is a dip, the room correction simply boosts the signal at the frequency of the dip. The problem is that if the dip is caused by cancellation, you can put any amount of power into that cancellation and it will be cancelled. So the dip remains.

That is why you have to break up the standing waves before room correction can really work.

If your listening chair is located in a null, room correction isn’t the solution for better bass. Relocating the sub is. Multiple subs provide an even bass response distributed around the room.

A 50 hz bass wave is 22 feet long. A 30 hz bass wave is 37 feet long. These waves are bouncing off the walls, ceiling & floor. Integration of subs with main speakers in a small room can be difficult. But it’s well worth the effort if done right. There’s a lot LF in music. Why not hear what the composers intended?

Rel and Kef are great. I currently own older pair rel subwoofers in my 2.2 audio system.

I would drop SVS. Not good at all unless you want a one dimensional boom.

pair is needed. I ran a single subwoofer for awhile and when I went to two it was very different and much fuller sound. Synthesizer bass effects became much more dramatic when panning between the two speakers as a lot of modern music does for effect. Drums sounded fuller and became more dimensional in the soundstage. 

I would drop SVS. Not good at all unless you want a one dimensional boom.

That’s just a ridiculous statement and not true at all.

@soix

have you ever compared subwoofers? Apparently not.
I have and stand by what I said per experience and am not some fan boy.

here is one review where the reviewer is kind to SVS and all its like brethren substandard like JB Audio, etc… Buy SVS if you want one dimensional boom that impresses the simple folks
