The options I mentioned in this earlier post would work well: https://www.martinloganowners.com/threads/what-causes-panels-to-wear-out.20113/post-214190
And if anyone wants some serious mid-bass dynamics, the answer is to deploy an MBM setup, which is straightforward with an 8-channel miniDSP or the six-channel DriveRack Venu360. See: https://www.martinloganowners.com/threads/mbm-deployment.17781/
The MBM is one of the most effective ways to make the system perform in the mid-bass area. Big action movies are a ton of fun, and dance music now has that chest-slam needed to satisfy. However, even classical music and solo piano (my standard) are not overdone and sound natural.
Many ex-ESL owners report returning to Dynamic speakers to regain that mid-bass hit. Had they deployed an MBM, they could have had the best of both worlds.
