The 1400LR satellites utilizes a single GLH (Graphite Loaded Homopolymer) driver and the sophisticated 1 in. LRT soft dome tweeter. The Low Resonance Tweeter is modified so it can play lower frequencies; far down into the midrange, about a full octave lower than a conventional tweeter to around 2,000 Hz. It’s a very highly engineered tweeter system with a vented back plate, playing into its own sub enclosure. Now the woofer doesn’t have to struggle to reach into the upper midrange, and we get a much smoother blend of radiation coverage angles as we transition from the woofer to the tweeter. The 1400LR is designed for smaller spaces such as dens or bedrooms, and is ideal for applications where cost and size are a consideration.
