On a down fire, where the motor rises into the cabinet, that shallow depth leaves plenty of room.

Height was set by the airspace, above the minimum the clearance alone would have required.\u003c\/p\u003e\n\u003cp\u003eJBL does not publish a position on down firing this driver, and this cabinet makes no claim on their behalf. The feet ship uninstalled, so if you would rather run it front firing or up firing, that is a decision you can make at install time without changing anything about the enclosure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003ePower, Mounting and Warranty\u003c\/h3\u003e\n\u003cp\u003eJBL rates the Club 102SL at \u003cstrong\u003e350 watts RMS\u003c\/strong\u003e and 1050 watts peak. The Club 102SL has one voice coil and JBL's Selectable Smart Impedance (SSI) switch, which sets it to 2 or 4 ohms without rewiring. The 4 ohm setting is the tighter alignment in this box; 2 ohms draws more power from a 2 ohm stable mono amplifier. Turn the amplifier off before switching. Confirm the load against your amplifier's minimum stable impedance before powering the system.\u003c\/p\u003e\n\u003cp\u003eJBL prints no bolt circle for the Club 102SL, so the baffle ships undrilled with a threaded insert kit and stainless machine screws: set the driver in the recess, mark its holes, drill, press the inserts and bolt it down. The enclosure carries a 1 year limited warranty. Bring your own Club 102SL; the driver is sold separately.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-cta\"\u003e\n\u003ch3\u003eCut for the Driver, Not the Catalog\u003c\/h3\u003e\n\u003cp\u003eBuilt one at a time in Tullahoma, Tennessee, with standoffs and a 1 year limited warranty.
