It sits 4.60 inches deep, which matters on a down fire, where the motor rises into the cabinet. Every Thiele-Small figure comes from JL's own owner's manual for the 10W1v3, both columns, and the table holds together: each column reproduces its own printed Qts, the two versions agree on Vas and resonance, and JL's own 0.55 cubic foot sealed box reproduces JL's printed Qtc of 0.853 and 0.868.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eTwo Chambers, Not One Volume\u003c\/h3\u003e\n\u003cp\u003eThis enclosure follows the Proline X standing rule for dual sealed builds: \u003cstrong\u003etwo fully separate chambers\u003c\/strong\u003e split by a bonded full height 3\/4 inch MDF divider, each driver in its own 0.55 cubic feet with its own polyfill.\u003c\/p\u003e\n\u003cp\u003eTwo drivers sharing one sealed volume interact acoustically.

At that height the floor slot is 0.93 times the cone area, under the 1.0 we aim for. With 11.4 mm of excursion this cone moves a lot of air at its limit, so for hard use mount taller feet or run the cabinet front firing; at daily levels the slot is not the limit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003eMotor Clearance and Orientation\u003c\/h3\u003e\n\u003cp\u003eThe motors rise off the baffle into the cavity, so on a down fire cabinet the clearance that matters runs to the top panel.

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\u003eJL rates the 10W1v3 at \u003cstrong\u003e300 watts RMS\u003c\/strong\u003e, 600 watts RMS combined. JL sells the 10W1v3 as a single voice coil driver in a 2 ohm and a 4 ohm version; a matched pair should share an impedance. A pair of 2 ohm versions lands on 4 ohms in series or 1 ohm in parallel. A pair of 4 ohm versions lands on 2 ohms in parallel or 8 ohms in series. Many amplifiers are not stable at 1 ohm, so on the 2 ohm version series wiring to 4 ohms is the safe default. Confirm the load against your amplifier's minimum stable impedance before powering the system.\u003c\/p\u003e\n\u003cp\u003eThreaded inserts are pre-installed on JL's 9.7 inch bolt circle, with stainless machine screws, so the 10W1v3 bolts straight in. The enclosure carries a 1 year limited warranty. Bring your own pair of 10W1v3; the drivers are purchased 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.
