"I like big bass, and I cannot lie
You other brothers can't deny
When a system sounds thin, with itty bitty bass,
And the sub's not in your face...

The floor plan is great but you need a proposed speaker location plan based on a reflected ceiling plan that shows lighting, fire protection, and HVAC. To get that you need ceiling height too.

If you look around that site you'll find their mini amplifiers too. I've used them in whole-house distributed audio systems, one per room. They work pretty well, and the price is unbeatable. Grab...

Yeah, pretty small point overall. There's vibration transmitted from the floor to a mic stand too. Big deal. But if you like the mic stand, could you perhaps suggest how to mount the puck mic to...

Yes, it's just that simple. You'll want to ID the speakers at some point so you know what wires go where.

Not really, but you could make them. Though I probably wouldn't bother.

The problem with picking dead center without it being the actual prime seat is that it's used for initial delay/distance settings. If you don't ever sit there it's not going to be "right" anywhere. ...

You can drive a nail with a wrench, you can stop a car with the emergency break, but neither device was intended to do those tasks optimally. Audyssey is designed to work best with data from...

I also admit to being puzzled by that one. So what do you use for measurement, then after you have the data, how do you apply it to EQ?

I like Op2 with the modification that no more than one measurement should be done at any one position. Audyssey's precision increases with more data, not duplicates of the same data. To to get...

Since Audyssey's measurement resolution increases with each measurement point, you'd want to use as many as possible. However, where you take them is up to you. It makes little sense to do multiple...

You would never use system EQ to compensate for hearing loss, for several reasons. The obvious incompatibility with those without identical loss, but also if you look at the curves of hearing loss...

Not so. The center channel provides between 70 and 85% of the total SPL in the room. Can't pull that off with dialog only.

Hard to get a definitive answer on that one because we really don't have the data on which to base it. All we can say for sure is "lower is better". Sorry!
