Martin-audio AQ215 超低音音箱

The AQ215 is a dual driver, direct radiating sub-bass in a heavily braced vented enclosure. It features two very efficient 15" (380mm) long-throw bass drivers with high power 4" (100mm) voice coils and generously sized low frequency ports for low noise, high power operation.
The AQ215’s extended low-bass response and high efficiency make it the ideal partner for AQ Series full-range loudspeakers where high power, extended bass is required from a relatively compact enclosure.
