Each driver's compression phase becomes the pressure environment the other is working against, which smears transient response and blurs the alignment each would have on its own. A full divider eliminates that entirely. Each L7T 10 gets its own \u003cstrong\u003e0.60 cubic feet net\u003c\/strong\u003e and its own polyfill, which is the same volume the single driver cabinet provides.\u003c\/p\u003e\n\u003cp\u003eThat means both products land on the same alignment. Qtc 0.745 per chamber here against 0.746 on the single, with an identical 51.3 Hz F3.

Kicker publishes a sealed range of 0.4 minimum to 1.0 maximum for the L7T 10, so each chamber sits near the middle of their own window.\u003c\/p\u003e\n\u003cdiv class=\"df-highlight\"\u003e\n\u003cp\u003e\u003cstrong\u003eGoing bigger buys nothing with this driver.\u003c\/strong\u003e At 0.60 net per chamber the L7T 10 produces an F3 of 51.3 Hz. At 0.80 net it produces 51.3 Hz. The corner frequency drops but the rolloff shape changes to compensate, so extension is flat across the usable range.

At 0.60 net per chamber that lands the anechoic F3 at 51.3 Hz, which reads high next to a shallow 12 on a spec sheet.\u003c\/p\u003e\n\u003cp\u003eThat comparison is fair on a bench and misleading in a car. This cabinet fires down into the floor, so the sealed rolloff meets rising cabin gain below 60 Hz and in-car response extends well below the anechoic number. The L7T was designed to live under a seat at 3 3\/4 inches of depth, and across a pair the 865 square centimetres of square cone and 14.2mm of excursion each do the work that a bigger box would otherwise have to.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"df-section\"\u003e\n\u003ch3\u003ePower and Wiring\u003c\/h3\u003e\n\u003cp\u003eKicker rates the L7T 10 at \u003cstrong\u003e500 watts RMS\u003c\/strong\u003e recommended amplifier power each, \u003cstrong\u003e1000 watts RMS combined\u003c\/strong\u003e across the pair, with 1000 watts peak per driver under ANSI\/CTA-2031-A.

Final impedance is set at the drivers. Available in Dual 2-Ohm (46L7T102) and Dual 4-Ohm (46L7T104), and you should use two of the same model wired identically, since mismatched wiring between chambers splits power unevenly. Confirm the resulting load against your amplifier's minimum stable impedance before powering the system.\u003c\/p\u003e\n\u003cp\u003eThe alignment figures on this page are calculated from the Dual 2-Ohm parameter set.
