Bipolar electrolytic capacitors which may be operated with either polarity are also made, using special constructions with two anodes connected in series. A bipolar electrolytic capacitor can be made by connecting two normal electrolytic capacitors in series, anode to anode or cathode to cathode, along with diodes.
There are 2 types of bipolar capacitors to consider; plain and raw. This refers to the type of foil used for construction. The plain type is the superior type and is constructed from smooth aluminium foil which has a low loss, providing better sonics.
@MattYoung They won't blow up. This is how bipolar capacitors are made. Using two electrolytic capacitors of identical value back to back is routinely used to get a non-polarized capacitor.
Historically bipolar electrolytics have been used in speaker manufacturing as they are relatively small and have a lower cost than film capacitors. Generally, the equivalent film capacitors are much much larger in size.
Bipolar capacitors generally have a higher ESR (Equivalent Series Resistance) than a similar value film capacitor, this is taken into consideration with the crossover design. So when upgrading bear in mind that this can affect the sound. Some people like to put a low-value resistor in series with a film capacitor when replacing a bipolar capacitor.
Upgrade requests on these are quite frequent but some of the values of bipolar electrolytics these manufacturers used back in the day are non-standard. Customers were having to reach the required capacitance by putting 2 or 3 capacitors in parallel.
