Exactly what did I buy? (Paradigm question)

[slmcdonald7]

My listening habits:
Exclusively two channel stereo. I watch some movies, but haven't bothered to hook up surround speakers.
I listen to a little of everything (sans country). That being said...

I don't expect subwoofer level bass, but when I run these without a sub, I listen to them and think "wow, these sound WAY smaller than they look". The highs and mids are great, but those bass drivers don't put out any really noticeable sound. I have taken off the grills and put my ear up to the bass drivers and felt them to make sure they were actually working more times than I would like to admit. This dissapointing sound is consistent, regardless of what type of music I am playing. I ran a pair of Paradigm Phantoms (v.3)before these, and the bass put out by those is comperable to what I am getting from my 11's. At your suggestion, I just listened to a very drum heavy track (one of Jimmy Chamberlin's finest) without the sub on, and had to turn it off because it sounded so bad. The bass is not tight and dynamic, it's not even there.
I have adjusted and readjusted every conceiveable setting on my 3805 to try and rectify the problem. Using the main fronts and surround A outputs to bi-amp, I have set both speaker settings to small or large, manually tinkered with the eq, and changed the db output countless times, and nothing helps.
I feel like a f***ing idiot for not just buying the Studio 40's, but since I am stuck with these I just wish I could listen to them and not feel dissapointed.
If I were to switch the + and - wires for the bass drivers on the back of the speakers (just to try something new), would I run the risk of hurting them?
Any other ideas?

Topspeed:
Good idea, and I would move my speakers and furniture around in a heartbeat if I hadn't had my Phantoms set up in the exact same position without running into this probelm. Thanks all the same though...

So, do my speakers just suck?

Thanks for your help,
