The Electro-Voice Xi-2181AF is a dual, 18-inch, low-
frequency system featuring Manifold Technology. Two woofers in the basic Xi shell optimize performance for low-
frequency enhancement of contemporary music (37
Hz three-dB-down with
EQ). The Xi-2181AF produces four times the acoustic output of the Xi-1191A - above 50
Hz - and features built-in L-
Track for Rigging. Its footprint is identical to the Xi-1153A, Xi-1183A, Xi-2153A, Xi-1191A (F), Xi-2122MHA, and Xi-1122MHA.
