3. Owner s Manual An Introduction Thank you for purchasing a JL Audio W7 subwoofer driver The W7 embodies JL Audios commitment to pushing the envelope of speaker technology with eight patented technologies a design patent and a completely unique set of component parts Each W7 model has been meticulously engineered to reproduce sub bass with extreme fidelity at any volume level provided it is installed and tuned properly Please review the information in this document carefully so as to maximize your enjoyment of the W7 s capabilities Two enclosure recommendations are listed for each model one sealed and one ported The sealed enclosure design will in most cases give you the best overall sound quality and take up the least space in your vehicle The ported enclosure design will deliver additional output over the sealed enclosure about 3 4 dB more and will also maintain excellent sound quality but it will require significantly more space to install The recommended ported enclosure is not designed for peaky competition SPL performance it is designed for music listening It will be very loud and sound extremely good when set up properly In addition to the enclosure recommendations we also provide recommended amplifier settings for JLAudio amplifiers used with W7 s Some of this information is also applicable with other brands of amplifiers like crossover points and slopes some is not like the voltage levels spec
