Unfortunately Anti-Mode X2 does not have a bluetooth module. The Remote App only works with Anti-Mode X4.

Yes, you can use daisy-chaining or Y-splitter to connect more than one subwoofer.

Anti-Mode X2 measures and corrects the combined response of the speakers, subs, and the room. It doesn't know or care about how many subs you have connected.

You don't need to adjust the sound pressure each subwoofer produces to be equal at the listening position. It is often best to have the subs at the same volume setting, so that one sub doesn't distort earlier than another.

There are 5 choices for the transition frequency fo the bass, treble and mid-range filters.

The default cut-off frequencies for the bass filter are: 80 Hz, 120 Hz, 200 Hz, 320 Hz, 500 Hz.

The default cut-off frequencies for the treble filter are: 1.5 kHz, 2 kHz, 4 kHz, 8 kHz, and 12 kHz.

The default Q values for the mid-range filters are: 2.00, 1.00, 0.50, 0.25, and 0.15. The Q-value adjusts the mid-range filter bandwidth (the smaller value, the wider bandwidth: b_w = f_c/Q).

You can enable the infrasonic filter to remove the frequencies below 15Hz that would not be reproduced by your system anyway. This releases some reserve in the amplifier and the speaker cone.

The infrasonic filter is only active in a calibrated unit.

The latency is about 7.2ms for an uncalibrated unit (i.e. "0.0") without tone controls.

For 2.X-calibrated units with any combination of correction and tone controls:

• Anti-Mode X2 Analog-to-Analog 18ms, Opt/Coax-to-Analog 20ms

• Anti-Mode X2D Analog-to-Opt/Coax 17ms, Opt/Coax-to-Opt/Coax 21ms

Before version 20240702 and since version 20250113 the latency of subwoofer-only 0.X-calibration modes is about 5.5ms. (No mid-range correction, no higher frequencies.)
