I have a pair of these for 2 channel music. I have stuffed the PS1400 ports with approximately 1.3 inches of open cell foam (sponge). I like the results. It seems to have tightened up the bass considerably. Can anyone tell me if there might be any drawbacks to what I have done? I have the stacks set up normally with the 130Hz crossover point to the PS1400.
Thanks, Mike
