It`s done a friend helped me measure the resonant peak, which was about + 4-5db at 80hz. The LCR network to get this flat is 18mh in series with 900uf in series with 5.6ohm across the bass speaker, in the Monolith`s case it`s easy to fit outside as the xover is outside the box. Just put it across the bass terminals on the back of the speaker. (btw this mod is NOT for MonolithIII`s with active IIIx xovers, only Monolith III`s using the IIIp passive xovers)
These values for the LCR are for my speakers which are 100% stuffed this may vary from the standard which is only 30% stuffed.
Anyhow the bass is now tight smooth and dynamic, much different to the standard one note bass the the Monoliths had.
One day i`ll do the standard measurements, but i like the detailed tight sound of an overdamped, low Q bass, it suits my not so large listening room.
I`ve done the measurment for the standard factory amount of stuffing and it`s the same, so use the same LCR components.
Cheers george
