It is usable to 500 Hz, although most subwoofer applications will be below 150 Hz. Best performance for this driver will be with vented enclosures between 5 and 9 cubic feet (142 to 255 liters), and vent tunings from 30 to 45 Hz. The Low Rider 18 is optimized for vented systems but will also work with appropriate singlereflex bandpass enclosures. Sealed, infinite baffle, transmission line, and dual reflex bandpass enclosures are not recommended. When the Low Rider 18 is driven with a power amplifier greater than 750 Watts, active filtering must be included. This filter should be a high pass 24 dB Butterworth at a minimum of 25 Hz. Failure to use filtering with high power operation may cause driver damage that could void your warranty. The extremely high output capabilities of the Low Rider 18 introduce the possibility of causing structural damage to buildings, as well as inducing permanent hearing loss, nausea, vertigo and intestinal disturbances in listeners.
