Where's the subs?

No, not the kind you eat; this is an audio blog afterall. :-)

The subs hang in the ceiling. We chose that for more even coverage, but especially so that those nearest them won't have that wind-blown look.

It seems of late, I'm getting more and more complaints of no low end. But I know I get plenty where I'm at in the mix position.

So, took a walk around this 270-degree room, and sure enough, there are seats where it is just gone.

What's the cause? Well, our absorption isn't completely installed yet. This means that the audio bounces off walls. Because of this, the sound will be louder in some spots because the signals combine to a greater amplitutde, and at other spots the sound is just gone, because the signals were of opposite phase and thus cancelled each other out. So you get these lobes and nulls if you were to map it all out.

So, be patient. Until we get the finished treatment installed to prevent all the bouncing around, we will have this problem.

It sure gives us audio guys a bad rap though.

Anyway, hope this finds you well.

Until the next time,

Ken
