Citronic LOSUB Low Profile Passive Subwoofer – LOSUB-15
LOSUB is a subwoofer design that offers high power handling from a cabinet that has compact dimensions. Employing a downward angled baffle, the LOSUB creates a pressure zone at ground level and ports this forward, meaning that the driver doesn't need a large air space behind the driver. The low profile of its cabinet enables it to fit underneath or alongside furnishings and in narrow spaces for installation. Input from an amplifier is via 2 Speakon connectors with a built-in passive filter to remove unwanted mid and high frequencies. Whether is it for space-saving during transit or storage or for building into discreet spaces for installation, the LOSUB passive cabinet can handle the power to deliver a strong sub-frequenciy response from a compact enclosure.
This is a practical option if you need a passive with clearly specified features and straightforward compatibility. The details below come from AVSL's current product information, so you can check the connections, size and performance before ordering.
