Back to indoor activities, I have a couple of LAB12's here that are under the knife. Actually, the only thing we've modified is the vent screen. We've removed them and are testing. Monte is testing airflow through the vent at various frequencies and excursions. I'm testing leakage through the gap; Actually, I'm testing the change of resonant frequency in various conditions: Free air, vent open, vent plugged, closed box and closed box vented to free air. Tamas is testing heat buildup and we may do that too, just to compare notes.

I thought you might find that interesting.
