JL Audio TW3 Series Subwoofer Driver


JL Audio TW3 (Thin-Line) Series Subwoofer Driver

TW3 drivers have a power handling of up to 400 watts RMS and are capable of MORE excursion than their famous cousin, the full sized W3v3. Do not let their small size fool you, as they share many core technologies with its TW5 big brother. To allow this remarkable feat to be achieved, JL Audio’s patented thin-line woofer technology compresses the architecture of the TW3’s using a "concentric tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of the large motor structure further forward in the speaker than with conventional designs. Due to their extraordinary performance, JL Audio uses the TW3 drivers in many of their premium PowerWedge enclosures, and vehicle specific Stealthboxes.

Although the TW3 Subwoofer can be driven with as little as 200 Watts, for best audio performance it is recommended to run an amplifier capable of between 300 - 400 Watts of continuous power per driver, like the JL Audio XD300/1v2. In addition, these subwoofers are optimized to operate in either a ported or sealed enclosures, needing only 0.80 cubic feet of air space in a sealed box and 0.95 cubic feet in a ported/vented enclosure. (Specific dimensions and figures can be found in the user manual, linked further below.)

When JL Audio sets out to make a product that sets the bar in its given field, they decide to built that product here at home, in the US at their Miramar, Florida factory. The TW3 driver is one of those products, and it shows in the amazing craftsmanship. Its this attention to detail that delivers the JL Audio quality and performance we have all become accustomed to.

Concentric Tube Suspension

Concentric Tube Suspension

JL Audio's patented solution to overcome the lack of mechanical clearance, presented by "low profile subwoofers", employs a molded structure which spans over the edge of the motor system, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large diameter voice coil permits the magnet to sit inside it, rather than surrounding the coil as is typical in most woofers. The concentric tube structure and the elimination of a conventional top-plate helps place the motor system higher up into the cone body's space to further compress depth, while still permitting excellent mechanical excursion.


Extraordinary Linearity and Control

Extraordinary Linearity and Control

DMA is JL Audio’s proprietary Dynamic Motor Analysis system and is aimed at improving dynamic motor behavior. As a result of DMA optimization, TW3 motors remain linear in motor force over an extreme range of excursion and also maintain a highly stable fixed magnetic field in the gap over a wide power range. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass. Its main catalyst is the driver's Ultra-long Voice Coil, that allows extreme linear excursion, phenomenal power handling and control, control, control.

Mounting Depth is NEEDED

The following review is for 1TRUCK12, which is a part of the bundle you are viewing.

One thing that NEEDS to be in the description is the MOUNTING DEPTH of the box. This is CRUCIAL for determining which speakers will actually fit in the box. Once I received the box, I estimated the mounting depth to be somewhere like 5.5" for the sub. So this does limit certain models of subwoofers, but the one I chose fit perfect. I also enjoyed that this box came with poly-fill. Sounds great with my Alpine SWE-12.

A Super super happy man!!!

The following review is for 1TRUCK12, which is a part of the bundle you are viewing.

I bought this Single 12" Subwoofer Angled Truck or Hatchback Box Enclosure a few days ago. So I cant explain how much happy I'm listening my music with this box, I'm an immigrant from Colombia who like to listen music such as Salsa, Reggueton, Merengue a real Latin guy. The sound is something so crazy (Perfect Sound - Space) in my car, Now I'm able to move all the toys of my son in my 2010 Toyota Matrix. If you want to have a good space & sound this is the box for you. Don't be scary for the size of this box. ;) I'm a happy Colombian.
