Short answer: the JBL HDI-1200P, cheaper and ranked higher. It costs $2,310, $190 less than the JL Audio E112 and ranks #32 of 212 against #34, built around a dual-ported 1000W 12-inch high-excursion cone. The E112 counters with a sealed 12-inch and 1500W RMS for fast, agile bass with transient detail and powerful output.

Buy the JL Audio E112 new; the JBL HDI-1200P is no longer sold new, so it only makes sense as a used find.
