FEQ X4 dramatically improves upon the original single antenna FEQ with 4-large broadcast antennas for a full 360-degree immersive experience. 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.
