Comments about JBL LSR4312SP 12" Linear Spatial Reference Powered Subwoofer:

This sub is essential for mastering with the JBL 4300 reference system in that it is the sole key to remote control of the entire system's crossover! You also get remote control of eq and subwoofer level after room mode correction with the system, but again - the trick to getting it right the first time is the crossover! Until you purchase this sub, you don't get to use the crossover! Changing the crossover is like having several monitoring systems! Setting the crossover at 125hz & muting the sub gives you the essentials of your mix: being able to balance vocals over music and the majority of your eq - it's like working with a set of small 4-5 inch monitors! Un-mute the sub and set the system crossover at 80hz to mix drums. You'll feel like your sitting at the throne! The stereo field is unbelieveable! Once you tame the drums, you're pretty much finished. Everything else gets mixed around them. Set the crossover at 30hz and your ready for mastering!
