The iW1 is NHT’s basic in-wall design. It uses a 6.5” woofer and a 1” fabric-dome tweeter. The iW1 has similar dispersion to a typical bookshelf design and works best when placed in rooms where the listeners are centrally positioned. Because of its co-axial layout, the IW1 can be mounted in the wall either horizontally or vertically. NHT has designed its IW1, 2 and 3 in-wall speakers using a baffle that is exchangeable for any of the three models. You can easily upgrade or replace each model without ever removing the frame from the wall.
