Kali Audio IN-8v2 (Second Wave) 3-Way Studio Monitor Review

[TheDichotomist]

So... Probably a silly question, and mostly hypothetical/overthinking ... but does anybody know if adding extra internal bracing to the cabinet on the IN-8 might damp the 160-ish Hz resonance? Or would even low profile added mass just stuff up the port tuning?

Are cabinet resonances even a problem in this speaker? I know they aren't super problematic in measurements, but at least in mixing circles, engineers have mentioned hearing the cabinet a bit, particularly in the IN-8 (v1) and seem to indicate that the bass reproduction (pitch and timing) isn't super great on these monitors.

It may. Below is from a paper by the folks at Technical University of Denmark (DTU).

Construction of Lightweight Loudspeaker Enclosures

They tested a bass cabinet. Figure 1 is the baseline. Figure 2 added some lining on the inside cabinet walls. Figure 3 added perpendicular bracing (see Figure 5 c). Figure 4 added interior corners triangular bracing (see Figure 5 d). You can see that there was a 170 Hz resonance that was effectively removed by the bracing. The lining was effective for attenuating the cabinet internal acoustic resonances.
