Engineered for big sound from a small enclosure, this woofer is optimized to deliver exceptional performance in extremely compact spaces—requiring less airspace than many conventional 12" subs and only slightly more than a typical small-box 10". Its patented concentric tube structure supports a massive 7" diameter voice coil, enabling outstanding power handling, thermal stability, and precise cone control despite its shallow mounting depth. A mica-filled polypropylene cone with a durable Santoprene surround ensures strong, consistent bass output with minimal distortion, even at high excursion.
JL Audio’s 13.5" woofer features Dynamic Motor Analysis (DMA) technology for long, linear cone travel with minimal distortion, delivering tight, clean, and articulate bass, while its cast-alloy, tab-ear frame provides strength and a space-saving design that fits nearly the same footprint as most standard 12" subs.


This subwoofer delivers full, accurate bass in sealed or ported enclosures, handling 250–600 watts RMS, while its ultra-thin 2-5/8" mounting depth allows installation in trucks, sports cars, and other tight spaces where traditional woofers won’t fit.

This is by far the best sub I ever owned dont let the price scare you I ordered two running off a old school zapco 600 competition amp on 2 ohms mono installed in a 2008 tundra crewmax custom built box out of 3/4 mdf dimension are 47 inches wide by 9 inches deep with a height of 22 inches high these subs really shine I think it will take a least 24 hours of beating to break these subs in so just buy it and you be amazed and happily overjoyed
These subs where everything I wanted and more the fit nicely behind my seat 08 F250 Super Duty. The Bass is out of this world, I don't think you could put more in it and it sound any better. I have two behind the seat with no modifications.
Might be a little pricey but for the quality, you'd really get what it's worth with this JL sub. Pretty amazing for a very shallow sub. Tight and punchy. Got some good power too. Allows me to save some space with its low profile.
