Get to know this product.
The 211ST 21” subterranean subwoofer was developed for high SPL bass output outdoor applications. In features a powerful 21” transducer for maximum excursion and SPL.There is no 70V version though it can be used as a 70V sub by being driven by an M1000 subwoofer amp which produces 70V output. No 70V transformers are used in the 211ST even for 70V application. All applications should be bi-amped.
James’ Landscape Speakers have mastered the mix of excellence in design, technology and superior sound... outdoor entertainment has never been so complete. The 70 volt system allows for runs up to a 1/4 mile without signal loss. Speakers placed in countless hidden positions can be aimed and sound suddenly snaps into focus: by the pool, next to guests mingling by the bbq or surrounding the tennis courts.
All Specifications are subject to change. An outdoor performance so discrete it is never found.
