Thanks. A rather more ambitious modification than I've made to my AG speakers! Personally I avoid mods to kit from well respected brands that can't easily be restored to original. That way, the used value can likely be maximised. In 15 minutes, the mods I've made to my AGs can be reversed.
I think you haven't read my article in depth.
I statet that all my modifications are reversible.
I not even drilled one hole.
Actually, as I now modified to a new DSP, I replaced the aluminum plate with cooling and have the Sub225 amp build in within 20 minutes.
And the Class D amps alone sound much better than the Sub225 amps
