There was a post here recently that included excerpts from an old article that provided a list of modifications for VOTT improvements for systems used in a home setting.

Anyway, the mods included:

1. Removing protective screens from compression drivers
2. Removing HF diaphram caps and using felt covered covers
3. Replacing "cheap" factory capacitors in crossovers
4. Increasing cab strength using additional wood bracing


Are these worth considering?
