About the JBL Stage 122D
Quality and affordability
Quality and affordability
Great bass usually depends on your wallet, as a nice sub and powerful amp can cost serious cash. Now JBL steps up with some help for the bass-hungry, designing their affordable Stage subs to help you get strong bass when your bank account's a little weak.
Excellent power handling
The 122D 12" subwoofer features a polypropylene cone for enhanced stiffness, supported by a high-roll rubber surround that'll stand up the abuses of life in your ride. It'll handle up to 250 watts RMS, and it works equally well in sealed or ported enclosures, so you can get the kind of bass you want.
Reliability
The dual voice coils allow you to wire this sub for 2- or 8-ohm impedance, while airflow from the cone's movement cools the voice coils for exceptional reliability. And, speaking of reliable, JBL puts these subs through a rigid testing process that includes baking, freezing, and blasting them with power for days on end, all so that you never have to worry.

Features
Dual 4Ω Voice Coils: For wiring flexibility, the subwoofer has dual 4Ω voice coils. When the voice coils are wired in parallel, the sub presents a 2Ω load. When wired in series, the sub presents an 8Ω load.
Sealed Box: JBL recommends a sealed enclosure with an internal volume of 1.4 ft³. Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music.
Ported Box: JBL recommends a ported enclosure with an internal volume of 1.6 ft³ using one 2.95" diameter x 4" long port, resulting in a tuning frequency of 34 Hz. They also recommend using a sub-sonic filter. Ported enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from a given amount of power.
Free-air Mounting: In addition to being compatible with sealed and ported enclosures, the woofer can be used in free-air applications. A free-air subwoofer is designed to be mounted on a baffle board, which separates the front of the speaker from the back. For instance, you could mount this woofer to a board attached to the rear deck or placed in the trunk against the rear seat. The trunk acts as the enclosure housing the subwoofer. Because there is no specific volume of air to stiffen the suspension, the free-air power handling is approximately half that of the woofer in a box, in this case 125 watts RMS.
Band Pass: JBL also recommends prefabricated band-pass enclosures. Band-pass enclosures often provide the most output available from any amplifier and subwoofer combination, but at the expense of sonic accuracy.
