Planning on a single flimsy wall and beefing up others unfortunately is pouring money down the drain.
For what it's worth, I wasn't recommending beefing up the other walls to deal with room modes -- it's likely to happen anyways (based on where the thread is going) in order to provide some soundproofing and I figured it might be possible to get a free ride from that work...
... I was hoping there might be an interior wall where soundproofing could be skipped, reducing the impact of the room modes. Then again if it's a full blown HT build it might be possible to add some serious bass trapping without adding a serious pile of ugly in the process.
