• Tall, Thin Design Gets Mids and Highs Above Audience
• Permits One Person Set-Up of a Remarkable System
The AT312 Attuned Top is a co-axial source array cabinet for
medium to short distance coverage where high output, a small
footprint and very high fidelity are required. It’s compact, simple
to use, easy to set up, attractive and capable of very high output
with superbly uncolored sound and natural musical character.
When combined with subwoofers like the SSP218 Profundo “Dub-ill”
Subwoofer, 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 an extremely substantial system ready to play
in a few short minutes by just one person.
When an AT312 is used with a BASSBOSS 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 reliabilty that are industry leading .
