Out of the 4350B data sheet the enclosure volumes are:Originally posted by Giskard
From PSS AUDIO's post, the six 4350 ports would tune that volume to roughly 26 Hz, and the spec sheet states 25 Hz.
Given the dimensions of the Westlake ports, I get roughly 22 Hz for a 9 cubic foot volume and roughly 19 Hz for a 12 cubic foot volume. I think it's safe to bet they're tuned to ~ 20 Hz
Low Frequency: 9.5 cubic foot
High Frequency: 1.6 cibic foot
Once again if this can help...
