TW3-Series 12-Inch 400-Watt Thin Subwoofer Driver, 4-Ohm or 8-Ohm DVC.

The 12" TW3 thin subwoofer driver by JL Audio offers a shallow mounting depth with an excursion capability that is remarkably capable of greater excursion than JL's W3v3 full size subwoofers.

JL Audio’s TW3 sub utilizes a patented thin-line woofer technology that compresses the architecture of the 12TW3 woofer using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and spider, while allowing the placement of the large motor structure to be moved further forward on the chassis than with conventional designs.

JL Audio 12TW3-D4 and 12TW4-D8 are optimized for small enclosures and offers JL's tab-ear mounting design to maximize cone area within their mounting footprints.

Deep, powerful and accurate JL Audio bass is now possible in more applications than ever.

  • Very shallow mounting depth (3.25 / 3.50 Inches)
  • No pole vent: permits mounting close to rear wall of enclosure.
  • Very small sealed enclosure volume requirements
  • Very long linear excursion capability (0.60 In / 15.2 mm, one-way)
  • DMA-optimized motor designs
  • “concentric tube” architecture
  • Patented “floating cone attach method” technology
  • Cast alloy frame
  • Injection molded, mica-filled polypropylene cone
  • Rubber surround
  • Aluminum-alloy dust cap and rear cap with JL Audio logo
  • Precision-built in USA at JL Audio’s Miramar, Florida factory with global components

Doesn’t stay cool long
Set name: UltraCool Pillow, Standard - Soft/Medium Firmness, Item length width: 30.0 Inches
The pillow was a little softer than I expected. It’s cool at first but at least for me heats up fast.

too soft, useless. but cool, kindah
Set name: UltraCool Pillow, Standard - Medium/Firm Firmness, Item length width: 30.0 Inches
the problem with these "cooling" pillows is any cooling effect is almost completely negated by a pillow case. this particular pillow is cool to the touch, but completely useless as it flattens out completely, way too soft I think for anyone. I would not recommend this "NASA" pillow for anyone for anything. Maybe for 10 bucks, but certainly not what they ask for this. I did keep it though. It is "cool" but only for a moment and your flipping it around like any other pillow. also way too soft. BUt, it has been cool enough to get me back to sleep.

Love it
Set name: UltraCool Pillow, King - Soft/Medium Firmness, Item length width: 40.0 Inches
I really like this pillow!! It’s a nice medium fluff. I do think it feels cooler. And, when you flip to the “cool side of the pillow” it’s realllly chilly. It’s very long - it sticks out of my king size pillowcase a little bit - but not enough to be bothered by it.

Worth the investment
Size: Standard (Pack of 1), Size: Standard (Pack of 1)
I’ve owned several. I toss them about every 5 years because well I haven’t found a way to wash it and not ruin it. I used to buy it at bed bath & beyond before they closed. And it was the same price there. It’s not memory foam. It’s latex. So if you are allergic- buyer beware. But it has a nice little bouncy- ness to it. Which I love. Cradles my head & neck. It has a zippered cover on it you can remove & wash. This one seems to have a thin, protective permanent cover thing on it. I assume so you potentially can wash the pillow. May attempt that in a few months.
