The new Signature 7NT In-Wall Loudspeaker, from B&W Loudspeakers, is based on the B&W Nautilus speaker series.
The 7NT is intended for applications where there is no available floor space or for use in architectural builds where in-wall speakers would be needed.
The speaker features a seven-inch bass/midrange unit, which employs a die-cast basket with fixed plug; Kevlar diaphram and oversized, 1-1/4-inch, high-temperature Kapton-formed voice coil. The in-wall system yields sensitivity of greater than 88 dB SPL at 1 watt/meter and offers power handling of 150 watts.
The low-frequency limit is 30 Hz (-6 dB), and response is 40 Hz to 20 Hz +/- 3 dB, with a top octave of -6 dB at 30 kHz. The 7NT incorporates a three-position tweeter-level control — -3, 0 and +3 dB.
