Description :
The Acoustat 2+2 are electrostatic speakers which run on electricity, and is part of the Mk-121 series. Its transformer designation is MK-121-2A. The speakers resembles the Model Four in that it contains four of Acoustat's full-range electrostatic panels per side, but differs from it in that two of the panels (per side) are stacked on top of the first pair to produce a radiating surface twice as high and half as wide as that of the Four. The 2+2 system towers almost to the ceiling, so it tends to dominate a listening room at least as much. The stacked configuration is not, however, for cosmetic purposes; it is to improve the system's vertical dispersion. When a line source extends from the floor all the way to the ceiling: the vertical beaming virtually disappears. With the Acoustat 2+2s, there is hardly any change in sound with changes in listening height. The listener can be on the floor, the ceiling, or anywhere in between without shooting down the system's high end. There are other advantages to the 2+2's stacked configuration. Two side-by-side panels, rather than four, reduce by a factor of 8 the amount of interference between them because each of the four interferes with all three of the others while two interfere only with one another.

A problem frequently encountered with wide electrostatic systems, but remedied in the Acoustat 2+2, is excessive excitation of standing-wave resonances in the listening room. Most listening rooms have many resonant modes in the 60 to 150 Hz range, but with some experimentation, woofers of smallish radiating area can be placed so that they generate relatively little activity from these resonances. But the wider the radiating area, the harder it is to avoid having at least part of that area in a location that sets off the room resonances. This tend to sound overly bass-heavy in all but the largest listening rooms, and the Acoustat 2+2 speakers are much less prone to the problem.

In sonic areas, the Acoustat 2+2s are among the most listenable speaker systems. Even their low end is better than full-range electrostatics, most of which tend to be full but loose at the bottom. The 2+2s still do not have the high low-end detail of a large transmission-line system, but their bass is very much in control, it has more detail and impact than most large electrostatics, and it blends seamlessly with the upper ranges. The high end is typical of electrostatics—open, airy, and incredibly quick in response to hard transients and subtle inner details in complex material. The Acoustat 2+2s are not, however, the most ultimately accurate speakers around. Although they will play cleanly at very high listening levels (over 100dB), they are a little lacking in dynamics. Loud, full-orchestral passages sound neither as loud nor as exciting as they do from some other systems. The user can, however, exercise some control over this problem by judicious orientation of the speakers. The suckout is minimized by toeing-in the speakers so their axes converge right at the listening seat, but this may add a slightly hard, steely edge to the sound.

If it is possible for a speaker to have too much detail, then the Acoustat 2+2 is a candidate for that honor. There are some things in reproduced sound that are better glossed over than heard, but at least a system like the Acoustat 2+2 gives an opportunity (via its treble adjustment) to vary the amount of such detail heard. These speakers also have far too much high-end "snap" to be listenable with most solid-state electronics. There is more extreme top end than musical accuracy calls for, especially in CD reproduction. CDs sounded most natural with the 2+2's high end pulled drastically down to around the 9 o'clock setting. With respect to imaging, the importance of symmetry in their physical placement cannot be overemphasized. Following Acoustat's instructions for set-up will yield the best result, as long as they're followed exactly. Properly set up, this stereo imaging accuracy and stability just wipes out anything heard previously from a large electrostatic. In their best orientation, it will be possible for listeners on either side of the center position—the "sweet spot"—to hear good, balanced stereo, with the center position best.
