Toe in on a sub?

Hey all. Im going to take the plunge. Idea is to mate the Tempest to a Martycube. I would like to sexy it up a bit and add some curves. Question is what would be the effect of toeing in the sub. I think it would look better to have everything on the same plane.

The bass frequencies are omnidirectional so it wouldn't make a noticeable difference.

The only issue with putting your subs with your mains is that the placement of the sub might not be ideal. But if you don't have multiple places you can place your sub, then it doesn't matter any ways.

The direction the sub faces doesn't matter as it is omnidirectional.

Cool unfortunately I don't have a lot of places I can place them so I'll have to live with it.

In my experience, the higher frequencies will be slightly quieter if you put the cone against a wall, but forward facing it can be off by as much as +-40 degrees at it won't have one bit of difference.
Once you approach 40 to 90 and then 90 to 180 degrees, that's when the higher frequencies become reduced slightly... not sure how many db's but I'd guess it's at least 3db per cone.
Below 50hz it doesn't seem to make one bit of difference it's free boundary-gain.

In my measuring experience ported sub facing seems to make a wee bit of difference, but you'll need to have a measuring tool to see if it's better or worse. Omnimic or REW for instance.






It is a measurable difference with my ported caps for instance on the direction they are facing, especially in the higher 'midbass', kick drum frequencies. A few dB here or there.

that could also be from not just the direction of the sub, but the distance as well.

Listen. It's All Good.
