New Member - Aerius i repair help

[Stephens3a7]

Good Morning. My name is Kyle Stephens and I am a recently new owner to a pair of Aerius i's. One of the towers is in working condition, while the other one has a bad ES panel and a blown power amp. I would greatly appreciate your advice on ES panel repair, as well as any/all mods that make these dynamite. Caps for power supply? After market ES Panels? Reinforcing the MDF to minimize the vibration? Modify with a down-firing sub and lower the over height of the ES Panel?

Thanks in advance!
