JBL P1222 PDF

All PRX Series speakers were designed to excel in sound reinforcement where challenging audio environments and loud volumes are the norm. For applications requiring full bandwidth sound reproduction, the PRX delivers the optimum balance. For live music, recorded music playback and speech the user has the option of tailoring the EQ. A microphone can be directly connected to the speaker input for quick PA applications. Coupled with a PRX sub-woofer the system becomes an efficient, full-range sound system. Sophisticated DSP is at the core of a fully featured input section, providing user selectable system EQ, protection, input sensitivity selection, cross-over functionality, dynamic limiting and discrete component optimization.

We recommend listening at low levels while driving. JBL accepts no liability for hearing loss, bodily injury or property damage resulting from use or misuse of this product. Power Series subwoofers are optimized to perform best in small, sealed, vented and prefabricated bandpass enclosures. For this reason, we do not recommend infinite-baffle mounting for Power Series subwoofers.

You should choose the enclosure you will use based on the type of music you listen to, how much amplifier power you will use for the subwoofer and how much space inside the vehicle you can devote to a subwoofer enclosure. Sealed enclosures provide more accurate sonic reproduction than other enclosure types, so they are well suited to all types of music.

Sealed-enclosure construction is straightforward and there are many prefabricated sealed enclosures available. An optimum sealed enclosure is always smaller than other types of enclosures optimized for a particular speaker, so they require the smallest amount of space inside the vehicle.

Vented enclosures provide better efficiency in the 40Hz—50Hz range but this efficiency comes at the expense of sound in the lowest octave below 40Hz and at the expense of some control and power handling. If you are using a small amplifier, a vented box will provide more bass output from less power.

Vented enclosures are also well suited to a variety of music types. Because vented enclosures require the volume of the enclosure and the size of the port to have a specific relationship with the characteristics of the woofer, the enclosure must be built exactly to the specifications provided.

While there are some prefabricated vented boxes available, matching a prefabricated box to a particular woofer is difficult. If you wish to use a vented enclosure, we strongly recommend having your authorized JBL dealer build it, or verify that your design is correct if you wish to build it yourself. An optimum vented enclosure is always larger than the optimum sealed box for the same woofer and will require more space inside the vehicle. Bandpass enclosures o
