Where to place - need some hand holding please


To all,
I bought a system based on my research here with no audiophile experience (Until than my stereo had been an Aiwa boom box from my college days.) I have been very happy, so thanks everybody. Now that I have had it for 1+ year and have become very intimate with it, I want to start calibrating, or flatten the response rather. I had hoped after spending some time I would appreciate the differences better.
Please click on my system link to view setup and pics.
Where do I begin? Speaker placement? I have no clue where to put them. Where should I try? My sub baffles me the most as it fires 3 ways so the corner is not an option. Sumiko said to place it between the FR & FL, but my center goes there and there is no room for anything else up there. My room dimensions are: 19'L x 11'2"W x 8'H.
To make things more challenging, if you look at the pic titled: “Front View” the toed in cabinets behind the speakers are not even on both sides of the room. One goes a 2 inches further out into the room.
I should also mention my severe limitations at this point. I cannot put any room treatments because of Wife Acceptance. Nor can I spend any more money on things like equalizers, again because of my wife, as she was not too thrilled with the money I put in already.
Based on these limitations, is there anything I can do to improve the responses, like speaker placement, etc? If so, where should I move the speaker?

Thank you in advance for any help,
David

Try putting your sub in back of your just behind your chairs, I have a floor fire HSU Research sub and I like it back there best, also your rears are in cabinets, could wife let you put some dampening in behind those, it wont be that visible, maybe also pull your mains out a bit more into the room.

Radio Shack SPL Meter mods corrections
I know that others here were interested in the specs to correct the non-linearities of the factory stock RS SPL meter. The figures below are to be either added to (+) or subtracted from (-) the readings that you obtain from your factory stock meter. In other words, the meter in stock form is EXTREMELY deficient when it comes to taking low frequency measurements. Keep in mind that these corrections are only valid under the following conditions. The meter must be set to C weighting, using 1/3 octave pink noise (easily available from various CDs), with the mic pointed at the speaker. These measurements were verified on both the RS analogue and digital meters using laboratory grade test equipment. Baseline testing was done using the 80 dB scale for reference purposes. While on the low side, this should give you a good baseline as to what your actually getting out of your system. Needless to say, if you had BIG peaks in the bass region with the stock meter and you weren't calculating in these correction figures, you're in even worse shape than you thought.
