1. The total system impedance of woofers in parallel can be calculated

– The suggested enclosure volumes are related to only one speaker, including woofer and duct(s)

using this formula:

displaced volume.

– For enclosures with more than one speaker, it is necessary to multiply the suggested volume and

duct(s) by the quantity of speakers.
