Q-Logic Box Types

• Type 1: Small, sealed box — produces tight, focused bass. The most accurate bass response of all box types, but requires more power.
• Type 2: Medium box — comes equipped with pre-cut port hole(s), port hole plug(s), and ports, so it can be used for either sealed or ported applications. More efficient than a sealed box, so you get more bass SPL with a little less accuracy.
• Type 3: Large Box — comes equipped with pre-cut port hole(s), port hole plug(s), and ports, so it can be used for either sealed or ported applications. Much more efficient than a sealed box, so you get more boom for your buck, but with less accuracy.
• Type 4: Bandpass Box — sealed/ported hybrid (a ported chamber houses a woofer that projects into the sealed area). Highly efficient, so you get lots of thump but lose a little accuracy.
