How do you know if you need to add a sub (without auditioning one, I mean)?


I like my speakers, I like the SQ of my system, so I'm not asking this question because I'm seeking a remedy to a deficit. I just wonder if it would sound even better with a sub. and I don't want to buy/audition anything based on mild curiosity. Also, like many of us, I don't have an unlimited budget and wouldn't care to stretch it unnecessarily.
How does anyone else decide whether to add a sub or play a pat hand?
My speakers are ATC SC40v2s. By specs, they don't go low. To my ears, the bass is much more satisfying than anything else I've listened to in my limited experience.

There is low frequency info in a lot of recordings that you are missing if your system cannot go down to 20 Hz. So the answer is you need a sub. I prefer a forward facing sub between the speakers, a stereo pair is better, and stereo towers are best. 
"...Is there a consensus as to how much one needs to spend to get a decent sub that really makes a difference?..."

You never want to buy a cheap sub but good affordable subs like HSU Research work really well.
