Default Sheetmetal intakes - runners extending into plenum?

In order to achieve an overall lower height profile (assuming everything is setup and built correctly) is there any disadvantage to having the runners extend right up into the plenum in orde to get 7'' length (as opposed to the runners being 7'' length but stopping at the bottom of the plenum and not going right up into it)?

e.g., like this



Worse top-range/mid/bottom power? Not an issue?

Nope...that's how mine is being done. Plenty of mid-range too.

Very purrrrty.

So there's no give and take? I would have thought having them extend past the floor would have caused some issues (e.g., worse downlow), otherwise wouldn't most people have the runners this way in order to cut down on height?

I think the trick is having a nice bell mouth or a nice rounded edge as in the Marcella pic.
