Did I really need a sub woffer in the first place?

other than for films...your energys are fine...get a turntable

I tried a sub with my full range speakers (not Energy) for a while, wasn't worth the time and effort as my speakers sound great without it...had to give it a try though.

I moved the sub to the hometheater where it gets a strong workout at movie time as an extra rear sub.

Like so much of marketing "just put it anywhere" is a cruel lie when it comes to two channel stereo. In home theater, just hook the thing up and the receiver does the rest with a dedicated channel and a volume match. A little boom just makes the show more exciting! Not so with two channel.
I would be wary of a dealer who took your money and then wants to charge you for "fixing it". First, I would get on the internet (like you are doing} and get some basic information on set up procedure. Measure your room size and see what frequencies are most likely to produce standing waves. Cross over as low as you can and move up slowly. until the "hole" fills. A reasonable starting position is against the wall 1/3 the length of same.

Proper subwoofer setup is an extremely time consuming endeavor. I have two and it took months using both listening and frequency response tests with an SPL meter to find the best location for optimal performance.

Try several locations around your room starting with in a corner behind your main speakers for maximum room loading and enhancement. Then move it forward away from the corner to reduce output. Try the other side. The, exactly between and level with your main speakers. Move it backwards towards the rear wall from that point. Believe it or not, a matter of inches is all it takes sometimes. Have faith, it will work wonders.

There are some great online guides to proper subwoofer integration, I will post the links later today when I get done with work.

Nonetheless, your Energy Veritas are rated 30-20kHz and are capable of really deep bass response when room loading is added in. You may get beter overall peformance by upgrading your amp and preamp without a sub.

For $2k + whatt you get for your current combo, you might want to consider other brands better than Rotel. I owned a Rotel 980BX amp and 990(?) preamp 5-7 years ago. They were great for the money, but not the weak on soundstage, depth, and spatial information. The sound also favored the "dry", hard, and lean side of the spectrum. Part of this could have also been the low end B&W speakers I had.

Check out Odyssey, Bryston, Monarchy, McCormack and other fantastic amp makers who fall in that price range. The difference will be HUGE. But, try a different preamp forst, I found Rotel's pre's to be the bigger weak link.

Have you looked at your room acoustics? My system used to require a Rel Storm, but after I treated the room, my speakers do just fine. It made a world of difference.

You might see if you have some nulls that are weakening your bass response. For me, a 30hz dip (more like a bottomless pit) made kick drums sound like they were 50 ft behind the rest of the band.
