Since some people will ask, i'm posting the LARSA sweeps of the LFR880s with port plugs. The bass hump reduction is very evident.

Additionally, i'm posting the LARSA sweeps when the DSP is set to a room boundary setting of Far 2 and then Near 2 (without the port plugs).
We could not hear any distinct differences in a limited listening test of these settings. That involved playing back a song and one person slowly switching from the DSP 'normal' setting to Far 1, Far 2, then back to normal and then over to Near 1, then Near 2.
The LARSA sweeps also seems to indicate such small differences, it likely explains the difficulty in hearing any thing significant.
