Atmosphere XL comes with ATM and is 53" tall with the spikes.
Atmosphere XL has four times the broadcast strength of the original Atmosphere to immerse you in Atmosphere’s seven acoustic scenes so convincingly you’ll swear you’re at the live event. Simply install the downloadable Atmosphere Control App to your iPad and select from a gallery of scenes. Your iPad then sends a Bluetooth command to Atmosphere altering it’s broadcast to recalibrate the acoustic response of all UEF products in your room to match the size and intent of which ever recording you’re listening to. Engineered to work in conjunction with either HFT’s or UEF Acoustic Panels and DOTs, Atmosphere’s signal wirelessly recalibrates the response or your room to better recreate your favorite recordings. In fact Atmosphere not only improves your acoustic and UEF Acoustic treatment like HFT’s and UEF Acoustic Panels and DOT’s, it also dramatically improves the function of all Synergistic Research UEF products including cables, Black Box, Ground Block and Tranquility Bases for a night and day improvement in sound quality.
