How It Works

Vertical Mode Control

Problem: Speaker Vertical Phase Cancelling

Solution: Control Vertical Modes with Monitor Stands

Problem

A typical monitor on a stand is located about halfway between the floor and the ceiling (left). The floor/ceiling bounce returns back to the monitor in a phase. This imposes a phase cancellation effect on the speaker's efficiency. Typically, the first cut is 74 hz for 8' ceilings. The engineer often boosts 74 Hz in the mix unnecessarily.

Solution

Studio monitors are nexted into a Monitor Stack, comprised of specially built TubeTraps (right). The Monitor Stack upsets the vertical symmetry in the room. The lower trap absorbs bass, the upper trap is short of the ceiling and vents bass. The combination eliminates the phase cancel effect and the engineer works in a linear environment.

Time Delayed Backfill

Vertical Diffusion from the AttackWall

The AttackWall absorbs early reflections and lets others escape to become processed into time delayed backfill. Without an ambinet tail to the ETC a reflection free recording studio would be exhausting to work in. The AttackWall is setup to vent treble in two ways. Some of the sound escapes over the top and under the bottom of the AttackWall. Other parts pass through the openings to the side and behind the engineer. Much of the sound that escapes the AttackWall reflects off the room walls back into the diffusing side of the AttackWall where it is again back splashed towards the wall. By this process a time delayed diffusive backfill of sound bleeds back through the opening in the Wall, over the top and under the bottom. The AttackWall creates an LEDE type mixing environment.

Additinal Lateral Diffusion can be achieved with completed side/back walls or the addition of a back wall.

The mix has to be not only good but it has to hang together. To get "the mix" the engineer has to work in a clean and linear acoustic environment. The AttackWall provides just that and one thing more: Consistency. Inside the AttackWall, the sound is the same no matter where it's set up. That means when you finally do move, your whole studio moves with you. Your electronics and your acoustics. Take a step towards complete control in the mix.
