When combined with subwoofers like the SSP218-A “Dub-ill”, the result is an extremely high-resolution 4-way active loudspeaker system with virtually unparalleled frequency response and dynamic power for its size. Its driver compliment incorporates dual 12” woofers in a vented enclosure for low frequencies and a 12” closed-back midrange driver with a co-axially mounted 1.4” exit compression driver coupled to a 40 by 60 degree horn. The 40-degree horizontal coverage per box allows arrays to be configured for 80, 120, 160, 200 degrees or more of horizontal coverage. One-man set up of a substantial system is made easy because the AT312 cabinets weigh only 86 lbs each.

Dual 12” low frequency drivers were chosen to minimize cabinet frontal area while delivering the best possible speed and impact in their operating range. Thanks to the narrow frontal area, the low frequency drivers couple coherently when multiple cabinets are arrayed, providing powerful mid-bass impact from a small, lightweight box. The 12” coaxial drivers also serve to minimize frontal area while maximizing output. The 12” midrange drivers are tightly spaced and the high-frequency lens is adapted to minimize midrange comb filtering.

The cabinets are built with a 20-degree taper on each side, allowing them to be tightly packed and maintain the correct 40-degree splay angle to match the high frequency lens pattern. The 48” tall box elevates the mid and high frequency radiators to a minimum of 7’6” on center when stacked on the corresponding subwoofer systems.

Transportation and set-up of the SSP218/AT312 combination is made easy because the subwoofers serve as a carrier for the tops. In most venues it’s possible to roll the system into place, lock the casters, tilt up the tops, plug in the power and signal and have a very substantial system ready to play in a few short minutes.

When an AT312 is combined with a BASSMAXX powered subwoofer the result is a very effective, practical, high fidelity 3-way active loudspeaker system. In most venues it’s possible to roll the system into place, lock the casters, tilt up the tops, plug in the power and signal and be ready to play in a few short minutes on almost any scale. The simplicity and ease of these components together will delight anyone who is regularly moving gear, coupled with fidelity and reliability that are industry leading.
