Flat response at 90 degrees?

Just reading this article by linkwitz:

LXmini-woofer

Is there any merit to creating a sub woofer using a larger 10-12inch driver in a transmission line tube like the LX mini - BUT having it point towards the ceiling?

I know bass is omnidirectional, but will listening at 90 degrees at ear level also help deliver a flater response to your ear as per the lx mini?

You've said it yourself - bass is omnidirectional. The orientation of a subwoofer driver isn't going to make much difference at all, though could have consequences with regards to cone sag.

Yea, I can only think of a few applications where driver orientation would matter - mostly for limiting out of band noise.

a) I think I remember someone running servodrive contrabass unit(s) pointed away from the listening position, to make the motor noise less audible.

b) A cheap way to get a higher order crossover. For example, some plate amps have a fairly low order crossover. Pointing the box away from the listening position could give a steeper (effective) crossover slope.
