Aren't electrolytic caps polarized? That can't be used for AC. Iirc these capacitors are film types instead.

Non-polarized electrolytics are somewhat uncommon, but they definitely do exist. They get used rather frequently in things like crossover networks for loudspeakers[0].

They tend to cost more, and tend to be larger than their polarized kins. They're not advantageous in circuits that always have some DC bias, so they only get used where it is necessary.
