DD's own sealed range for the SL710 is 0.5 to 1.0 cubic feet, Qtc 0.77 to 0.68, and a maximally flat box would take 0.75 cubic feet. This cabinet sits inside that range, toward its larger end and a little larger than the maximally flat box, so the SL710 sits just under flat. In 0.90 cubic feet the SL710 lands at Qtc 0.687, just under maximally flat, well controlled, with system resonance at 49.4 Hz.\u003c\/p\u003e\u003c\/div\u003e\n\u003cdiv class=\"po-highlight\"\u003e\u003cp\u003e\u003cstrong\u003eThreaded insert kit ships with this box.\u003c\/strong\u003e DD Audio publishes no mounting hole locations for this driver, so the threaded inserts are not pressed at either position before it ships.

A D2 pair wires each woofer's coils in series (4 ohms) and the two woofers in parallel for 2 ohms, or everything in series for 8 ohms. A D4 pair wires each woofer's coils in series (8 ohms) and the two woofers in parallel for 4 ohms, or each woofer's coils in parallel (2 ohms) and the two woofers in parallel for 1 ohm. A 1 ohm load needs an amplifier rated 1 ohm stable; if yours is not, use the higher option.
