Our newly designed, aluminum alloy X1-ANC Speaker with Adjustable Noise Control (ANC) delivers big sound quality in a small compact 1lb package. With a peak sound level output of 91dB, this speaker offers an impressive bass, dynamic midrange and distinctively clear higher frequencies. Bluetooth 5.3 connectivity makes it perfect for streaming music from your iPhone and Android device. Paranormal enthusiasts will find the X1-ANC speaker sound and performance perfect for use during Spirit Box sessions. It is used with our P-SB7 (all versions), P-SB11, PSB7-PRO, APF Processor, DAS-ANC, and ANC-Mini and all other sweep radio devices. Interactive function buttons along with a convenient volume control ring located around the top of the X1-ANC make adjustments fast and easy.
 
The ANC utilizes a proprietary software algorithm that dynamically adjusts the Audio "Hold & Release" properties which enables a more clear Spirit response that can be better heard and deciphered by the user.  These responses can be better heard and deciphered by the user during their Spirit Box sessions and when combined with a speaker, will provide a more amplified response.
