The new FEQ X4 dramatically improves upon the original single antenna FEQ with 4-large broadcast antennas for a full 360-degree immersive experience. This is our ultimate set it and forget it acoustic field generator and is perfect for people who want increased performance from their audio systems and SR products with UEF Technology but without the complexity of the iPad controlled Atmosphere. Moreover, while the FEQ X4 is larger than the original single antenna FEQ its still small enough to hide in furniture, behind drapes and sofas, or in bookcases for the ultimate in invisible acoustic control. FEQ X4 is a single channel ULF (Ultra Low Frequency) RF pulse generator that acts as a low-frequency dither to overpower the ambient RFI and EMI fields in your listening room broadcasting over (4) separate channels for a more immersive experience than was possible from the original single and smaller antenna FEQ. In addition to acoustic benefits, it also improves the performance of all SR products with UEF Technology. UEF Tech responds to specific ultra-low frequencies so your Core UEF, Atmosphere X, and Galileo SX cables perform better, along with your HFTs and UEF Acoustic Panels. Even Tranquility Base UEF component platforms and Black Box low-frequency resonator arrays perform with noticeably increased levels of performance when excited by the strategic ULF signal generated in a 360-degree wave pattern from the new FEQ XL4. Dimensionally the chassis and antennas were extended from 7 to 14 giving the FEQ X4 approximately 8x the broadcast strength of the previous generation FEQ with a 360-degree radiation pattern to the originals 180-degree pattern so placement is less critical while overall performance is increased. To use, plug the FEQ X4 and its internal Ground-Plane into two separate wall sockets in your listening room and place behind and between your two main speakers or where ever you find space. Then turn it on for an immediate and unmistakable improvement in sound. One FEQ X4 will improve an average size listening room with a greater sense of clarity, a lower noise floor, and more natural harmonics.

Dimensions - 14 tall (Base 4.1 wide x 4.1 deep)

ULF X4 Technology
ULF (Ultra Low Frequency) X4 technology adds four times the broadcast power of the original models. Incorporating four antennas, X4 models provide a 360-degree signal dispersion pattern, significantly improving the effect of the Atmosphere XL4 and FEQX4. In addition to acoustic benefits, it also improves the performance of all SR products with UEF Technology. UEF Tech responds to specific ultra-low frequencies so your Core UEF, Atmosphere X, and Galileo SX cables perform better, along with your HFTs and UEF Acoustic Panels. Even Tranquility Base UEF component platforms and Black Box low-frequency resonator arrays perform with noticeably increased levels of performance when excited by the strategic ULF signal generated in a 360-degree wave pattern
