Have you verified there IS a resonance in the motorboard? I don't think mine do.
As to the splitter, it it the beginning of the horn and the expansion rate is important there, so I'd calculate carefully the impact of change you are proposing.
No I'm not proposing a change these are the way they came stock. The splitter, that is. I'm very satisfied with its performance. Mine's an older model , with doghouse hatch under the mid-range horn. That's why my Splitter"s the larger one, I imagine. Thanks guys for your input!Sent from my SPH-L720T using Tapatalk
