My priority is zero noise transmission to my neighbours, as I live in an apartment
Do spikes isolate or lock the speaker to the building structure? If I sit it on pads how much would that affect their quality of life?
Obviously volume is most key, that’s never over moderate, but I want to enjoy my music without being a total dick to those around me
You can never really insulate from your neighbors in an apartment without serious sound insulation and strong, immovable walls, floors and ceiling such as a concrete apartment building with sheetrock inside.
The problem is that the deep bass that you enjoy from your system will transmit, through the air, and make your wood/sheetrock walls, ceiling and floor into resonant diaphragms.
You may be able to insulate your neighbors from higher frequencies with acoustic insulation, but the bass is problematic
