Subsonic Filter

[Philanthro 0]

Does anyone know of a standalone subsonic filter you can buy?

My friend bought a Kicker ZX700.5 and it doesn't have one... But he doesn't need a full audio processor or crossover, just the subsonic filter.

I'm looking for something that preferably hooks into the RCA's, but if there are any other options please let me know.

Thanks for the help

Ahem....

Infrasonic filter.

Subsonic implies it is slower than the speed of sound.
