Help Finding Thread/Post

I'm trying to find a thread that was discussing extreme ways to reduce boom with MA RS6. Initial response was from David under the FrankHarveyHiFi account suggesting disconnecting the bass driver. The post I'm really trying to find was from MA's Dean Hartley in which he suggested attenuating the bass driver by replacing the jumper bars with resistors while connecting the amp to the HF terminals.

Try as I may I can't find the thread so wondered if there was any chance Admin could have a look if they have access to better search tools?
