"like a choke was removed"
That is a very good and accurate analogy... I have to remember that one..
Well, getting rid of the wife which could be complicated, messy, and/or expensive depending on your approach...
There is nothing wrong with trying a test...your wife should not object to a half day of testing and tweaking in your home theater.
Turn off all Auto Setup features such as Audyssey.
Try moving both of your subwoofers so they face 90 degrees away from your listening position ... you do NOT want any direct radiating sound reaching your listening position. If you have a downward firing sub, this is not necessary.
Then, position the Subwoofer so they each 11'4" from your listening position ..... same as you main speakers and surrounds. Where you put the Subwoofers makes no difference ... as long as you are anywhere on the "ARC" of the circle as shown in the diagram I posted.
If you have a downward firing subwoofer, place a marker on the top dead center of the cabinet and use that as your measuring point for reference.
If you have a front firing subwoofer, measure to the front center of the driver if you can. In my case, I cannot measure from the listening position to the front center of the sub driver as it points to the outside right side ... away from me. I cannot see the driver from my listening position. In this case, place a marker at the top front center edge of the cabinet and measure from there. The front top center edge of the cabinet is basically the same distance as the front of you Subwoofer driver. That will work as your reference.
Once all speakers are set to equal distances, set all your delays to 11'4" in your AVR.
Then, make sure your AVR is set to the proper configuration (5.1, 7.1, etc.) ... and set your speakers to LARGE ... assuming they can go down to 80hz more or less.
Then, set your AVD Crossover point to 80hz.
Once all this is done, if you have an SPL Meter, use the reference tones on Disney WOW or some other calibration disc to set all Main & Surround Speakers to 83db +/- 0.5db reference level.
The set your sub +3db hotter (86db) that the Main and Surround Speakers.
Take your time and check it twice to be sure it is all done correctly.
Ideally, you would also want to use air dried maple wood bases with brass footers to isolate the subs as well as brass footers for all of your gear with an air dried maple wood equipment stand for best results.
However, assuming that is not the case, proceed to the next step which is adjusting your LFE Levels. Turn one Subwoofer off and do one sub at a time. Once one is done, turn that one off and do the other. Then turn them both on and you may find you need to turn down the LFE level a bit ... or not.
* Adjust your LFE Level on your sub ... less is more ... always. I use a Reference 5.1 MUSIC DISC to set the sub level.
* I listen for accurate, tight, defined, crisp note accurate bass and a proper blend and smooth transition from low to mid to high frequencies. Despite common misbelief, a properly dialed-in sub will greatly improve mid and high frequency response.
* Listen for natural and accurate tonal balance ... smooth transitions ... and any indication that your midrange and highs are being impacted.
* Listen and turn down your LFE Level if the bass becomes even slightly muddy, boomy, or in any way overly present, dominant or localized. You do not want this.
* When your LFE Level is correct, you will have a seamless transition from low to mid to high frequencies.
Last but not least, take a few reference BD Discs with Uncompressed 5.1 or 7.1 soundtracks or at the very least DTS-HD-MA Lossless Audio tracks.
Most important of all ... use Blu-ray Discs you are very familiar with.
A few I use are:
* House of the Flying Daggers (Drum Scene)
* Dances WIth Wolves
* Jeff Beck, Live at Ronnie Scotts
* Disney WOW
and numerous others...
Listen for the GOOD things that should now be evident compared to your previous setup ... like the following:
* Sub "disappears" in the room ... becomes one with the room so to speak. You cannot localize it or identify its position in the room. Bass should just fill the space and come from everywhere.
* Bass is crisp, tight, transient and clean .... not boomy, blooming, poorly defined, flabby, tubby, or overly present or dominant.
* There is a fuller, more rounded, overall better balanced sound with greater detail, definition and imaging.
* You notice an improved soundstage with easily identified subtle details and better definition across the range ... especially in the bass to mid-bass and lower midrange areas.
* More natural vocals and overall organic sound quality that is more true to life verses reproduced.
If you decide to try this, please let me know what happens...

I'm not happy with my Subs, Wife won the battle of placement-->
Mains (L_C_R) are 11.4' to sweet spot.
Subs are located: one on left side wall facing right wall, 9" out from side wall & 26" from front wall, 10.6' to my sweet spot.
One in right corner 9" from each corner & 12.4' to sweet spot facing left wall.
I have been approved (
) to move left sub to corner (table swap with sub) if I decide to relocate it.
Richard, what is your opinion, just live with what I have, place both in corners facing opposite walls or go with only one Sub (Can't relocate/replace/remove Wife!!)?
