    So the design is RFZ?

    Use caution with reflective front ends when using nearfields because the SBIR will be more pronounced.

    Broadband treatment CAN be effective down to 40 Hz, but it needs to be about 16" deep. To really cover the LF range below 100 Hz, you need to use a combination of Broadband and membrane trapping. Placement is also critical to the trapping efficiency.

    Cheers,
