can subwoofers make things worse?

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

Sudnh

I love it...." the simple folks "  yes indeed 

YES.  Other than truck/car audio and HT the money spent on subs could be added to a speaker budget and if one's strapped for cash there's plenty of used, floor standing active speakers out there that will deliver the goods and take less floor space.
