I inquired about this a few days ago but am still unclear.
Below is John's design for the corner absorbers.
Should the 703 be placed as in example "B". That is, with a space between the different layers of 703?
Or, as I've shown in example "A". Fill the cavity with 703?
Thanks,
Earl
Still unclear on corners absorbers

Neither; here's an update I did a few months ago

General rule of thumb is, for a slat resonator you want roughly half the depth filled with insulation; for a corner trap, a single piece of 3" or 4" 3 PCF is fine. Place as shown/described in the above link... Steve
Thanks! That clears it up for me.
