Single vs. Dual Subs

mc, Why state the obvious, then attempt to justify it?

Why have two Low Bass Stereo SUB Woofers, when as you state it's difficult to record  Very Low Bass Frequencies in Stereo?

Wouldn't summing Left & Right Low Bass Frequencies Electronically, (which can be done efficiently, with a Summing Electronic Cross Over) then playing them back from a Central Low Bass Sub Woofer, as I suggested, provide a better option?

As I indicated, I still have Stereo Bass from my 12 Inch Sub Woofers for Localization of those Mid Bass Frequencies; via their placement on far left & far right, which provides such localization for those frequencies.

Providing Very High Power to a Single Centralized Low Bass Sub Woofer definitely puts the SLAM into those frequencies, which can be felt, but not heard by most people.   

Try it, I guarantee that you will like it!

Properly integrating a sub is really hard work, and rarely done by 90% of those who buy a subwoofer.

As a result most audiophiles have never heard a single subwoofer properly set up and think that stereo subs matter for the sake of Left/Right imaging or sensation. They do not if you set them up correctly.

They matter for frequency smoothing, and then only in cases when you have absolute control of their placement, and then, only somewhat.

Better room acoustics and EQ can make a single sub sound glorious and enhance the experience from dual subs as well.

Most audiophiles also try to stick to subs below 40Hz, when in fact cutting off their mains at 80Hz or so tends to greatly reduce doppler distortion (assuming small 2-ways) and increase the amp dynamic range.

Sadly people tend to want to just throw money at a problem that needs expertise. Hire an expert, or get a system with built in room calibration and sub management. You’ll be really glad you did.

Amen!

Technically, correct! I would even go as high as 100%. But 90 will do. Which is why I always and only recommend a DBA with 4 subs. Try and do it with just one and you are doomed to failure. When even the guy who uses one knows it is really hard work, and even then works only rarely, everyone should listen. 

And then go out and get more subs. To do it right. 

My listening room doubles as living room so sub placement was dictated by furniture. Even so the Audiokinesis Swarm sounded fantastic out of the box. I am sure I could fine tune it if I had a dedicated room but this is already wonderful with minimum effort
