Capacitor value for tweeter protection with active crossover
2) make the protection capacitor large enough to work 2 octaves below (my choice) or a decade below (almost same thing) so it does little if at all. In any case, don´t overthink it. Personally I don´t worry about any input signal problem but the feared blown power amp which applies brutal DC to very weak tweeter voice coil.

Capacitor Banks: What is a Capacitor Bank? Advantages & Uses
A Definition. As the name implies, a capacitor bank is merely a grouping of several capacitors of the same rating. Capacitor banks may be connected in series or parallel, depending upon the desired rating. As with an individual capacitor, banks of capacitors are used to store electrical energy and condition the flow of that energy.
Surge capacitors provide cost-effective protection of
Surge capacitors work by absorbing the energy from electrical surges, providing protection to the equipment. Benefits Eaton''s Cooper Power™ series surge capacitors are engineered to provide the following benefits: • Compact construction—for easy implementation in tight enclosures such as metal-enclosed capacitor banks, motor
Protection of capacitor banks by fuses during energization and
2.2 Multiple step capacitor bank. When the bank in position n is switched on, supposing that the (n-1) other banks have already been switched on, the oscillatory load will be identical.However, in this case, the other banks connected in parallel will act as additional sources of very low internal impedance.. This internal impedance (inductance …

Delta Lightning Arrestors
A surge capacitor reacts continually, therefore the capacitor will react to any increase in voltage. Surge capacitors can handle fast low energy surges that can get by a MOV, a surge arrestor, or a surge suppressor. Use of bot the Delta Surge Arrestor/Suppressor and the Delta Surge Capacitor will provide more complete protection.
