Post Subject: Thoughts on alignment: Direct vs Reflected mid-bassPosted by jessie.dazzle on: 4/26/2010

Facing similar issues, until confirmed or disproved by experimentation, the following represents my view:

Situation 1):
Mid-bass horns aimed generally TOWARD listener's ears:
Alignment of the DIRECT OUTPUT of the horn for time arrival to listening point should take precedence.

Situation 2):
Mid-bass horns aimed clearly AWAY from listener's ears:
Alignment of the 1st REFLECTED OUTPUT of the horn for time arrival to listening point should take precedence.

I would interpret Bill's installation as belonging to Situation 1.

I would interpret Romy's proposed installation (mid-bass horns mounted above and behind listener) as belonging to "Situation 1.25" (leaning more toward Situation 1).

In the event Situation 1 does not allow the bass to mature before reaching the listener's ear (can we say that this is likely the case in all but really huge rooms?), it would seem desirable to keep that immature bass away from the listener, and therefore Situation 2 may be the better alternative.

Assuming situation 2 is possible, receiving mid-bass primarily as reflected sound, one would have to take into account the reflected path of that sound, and how it describes the mid-bass part of the image, relative to the MF/HF part of the image; for example, the reflected mid-bass may very well originate on the left, but reach the listener's ear from the right.
