Jl Audio 10tw3-d4 Review

Motorists who drive a sports car or regularly haul a lot of stuff know that they can’t just add some bass to their rides. The same goes for those who transport their family members on a daily basis. If you’ve always wanted to hear low notes in your ride but wary about the space a subwoofer would take, consider getting this shallow mount sub from JL Audio. Jl Audio 10tw3-d4 is budget-friendly with average bass output that should satisfy most listeners.

This 10 inch subwoofer has an ultra-shallow mounting depth of 3.25 inches. It requires minimal air space so you can use a small enclosure for it.

Despite its size, you would be surprised at the sound that this sub makes. Many reviewers on Amazon are happy with the performance of this sub.Jl Audio 10tw3-d4 Shallow-mount

High-performance cone:

At the core of this subwoofer is its tough cone. Made of polypropylene, the cone is designed to withstand resonance. It won’t flex under high power,

so you can be assured that the subwoofer will continue to perform well even after long hours of listening. Surrounding the cone is a large, durable rubber that allows the cone to move large amounts of air.

Cast alloy frame:

Housing the subwoofer is a cast alloy frame that stands just 3.25 inches tall.  It may be compact but it gives a very stable housing for the high performance  This further increases the lifespan of the subwoofer.

Wide power handling range:

With an RMS of 100 to 400 watts, this subwoofer has a wide watt range for RMS power handling. This means that this sub is capable of projecting clear, clean, and accurate bass lines.

Concentric Tube suspension:

This jl audio subwoofer is equipped with the brand’s Concentric Tube suspension technology. Its molded structure has a large voice coil with the magnet situated inside it. This eliminates the need for a top plate, further compressing depth and enabling the sub to deliver superior sound despite its size.
