Placement of subwoofers

Hi All. I would appreciate your views as to the placement of subwoofers in my system. I attach 2 pictures of my room for your reference below:-

Based on the reading that I have done, I understand that the subwoofers should be placed alongside / parallel to the main speakers, and not behind them. If this is so, should the subwoofers be on the inside or outside of the main speakers? Right now they are positioned on the outside of my main speakers, but they are behind them by 1 to 2 feet. I feel that this is a system weakness and have been contemplating relocating my subwoofers as a result. 

Also, my subwoofers are placed very close to other bulky furniture, which leads me to wonder as to the effect on the sound emanating from the subwoofers. Will this effect or otherwise block the sound from my subwoofers? 

FYI due to the WAF, I unfortunately have limited choices in the placement of my subwoofers. 

Any input would be welcome.

Thanks!

Can you describe what you may sense is lacking with your current sub bass speaker positioning?

I may be misunderstanding your response. 

[FYI Some manufactures offer Bluetooth or Wi-Fi connections as well as manufactures of decent quality custom length RCA or XLR cables available to bridge this new positioning.] 

You've placed one of your sub-bass speakers at the listening position and played a low frequency cadence of test tones through that sub and the main speakers while walking about the room? 

The priority is to map those areas where the bass energy is the loudest, ie. bass modes. It's not unusual for the next or lesser bass mode usually asymmetrical to the first. With the furniture out of the way map all the bass modes, everything else in the room is a null where low frequency is more difficult to achieve and control. 

With your sub-bass speakers positioned in the vicinity of these bass modes you'll be reducing the volume to your taste (shyness). You should hear an improvement in room loading and a more detailed low frequency presentation at the listening position using less gain. 

In my experience with your sub-bass speakers I found the addition of third party signal processing such as the DSPeaker to be very useful as have a majority of users making it a very questionable omission by manufactures.  

Despite the advantage of any signal processing, your sub-bass speakers remain a steep -6dB near the 30Hz region which usually limits extra low frequency output. Depending on your musical taste this may be a preferred non issue. 

All the best with your outcome.
