Arraying

The TQ-440 has a side-wall angle of 16º. Use this position for smooth horizontal dispersion that is ideal for many applications. With the high dynamic range capability and low power compression of the TQ-440 you should find this wide angle arrangement adequate for all but the most demanding long throw requirements. It also has the advantage of needing fewer cabinets to cover the required area.

When speakers are mounted together in close proximity either stacked on top of each other or arrayed the output increases due to the coupling effect. For instance, stacking two cabinets on top of each other with the top one inverted gives around 4.5 dB increase in the mid/high section, ideal for long throw in large halls, sports stadiums, etc. Mounting the bass drivers close to each other gives the same gain at the low end. When the system is arrayed for wider angle coverage with cabinets side by side the gain is in the order of 3db.
