Has anyone tried "anti-parallel" capacitors in speaker crossover?

We know that capacitors with same capacitance in parallel reduce overall ESR ,and dig quite a bit "deeper" at same resonance point "valley" as well.

Some researches suggest that anti-paralleling such identical capacitors (non-polar) make such effect more pronounced:

Since capacitors in speaker crossovers are mostly non-polar, which would certianly be safe for anti-parallel, but with "resonance point" altered, would it screw up "transition" between driver's frequency? Has anyone tried?

The issue with resonance is related to 50Hz and 60Hz "signals" - Chip647 13:49:26 01/14/24 (0)
