How do I know when to use a subwoofer?

Thinking of getting a Rel S/812 sub. Now have Tetra 606 $30K speakers that go down to a true 27Hz. I feel that I may need a sub and that I should be able to get more impact out of my system with one.
I mostly think of more excitement when using the system as a 2.1 theater system at night. Although it should make my music listening improved as well. I like the Rel way of allowing the main speakers to play full by the connection to the amps. However, I do like to think that my Tetras produce “natural” lows and I should be quite happy with them.

I’m on the same journey. So playing with options. A sub or subs can make all the difference if set up well.

I use a single wireless Rel S/5 SHO with full range speakers and the difference is beyond satisfying.  It's very natural, seamlessly integrated, quick, tight and punchy.  Placement can be counterintuitive. It super delivers in the right location/orientation. It super disappoints in the wrong one.

Do you want your music to sound "real" or artificial?  I've heard systems that upon first impression sounded really good with tons of bass.  However, upon further listening, I determined that it was artificial.  

Real accurate reproduction, not chest thumping sound that really wasn't there when recorded.  If the speaker was designed to provide accurate bass response, then subwoofers are overkill.  Not saying that they can't be dialed in to take the load off the main speakers, but, do the manufacturers recommend using subwoofers?  That is a very good question to ask.

It's a trial and decision that one should go on very carefully.  Might be necessary depending on your room and current speakers, but most rooms and equipment where they brag about the bass response, I've found had way too much bass.

@minorl , 
Very good points.
@OP,
The issue of the bass you are experiencing may be due to your equipment, room treatment/ or lack of, as well as cabling, not to mention speaker placement.
Rather than chase a shadow, I suggest PM'ing Johnny Rutan (audioconnection). He knows his stuff and can save you a lot of wasted time.
Yup, he is a dealer, but he won't try to sell you something, only give great free advice.
Of course, you can also post your system here, as well, but you'll get a lot of mixed information that will probably keep you as bewildered as you are now.
My 2 cents:
Trust me, trust Johnny. Of course, you can do a search here on Audiogon to confirm.
