The IC8-AW is a two-way in-ceiling loudspeaker with IP54 protection, sold as a pair: a 20.3 cm woofer and a 25 mm titanium tweeter bring full bass to covered patios, bathrooms and damp rooms.
IC8-AW: construction and moisture resistance
The IC8-AW combines the drive units of MartinLogan's largest ceiling model with a build designed for damp conditions. The 20.3 cm woofer takes the response down to 45 Hz and keeps the low end energetic even in spaces open on one side, such as a covered patio; the 25 mm tweeter handles the treble up to 20 kHz from 2,500 Hz. Sensitivity is 90 dB and the impedance suits 8 ohm amplifiers, with quoted power of up to 90 W.
Three measures set it apart from the indoor version. The crossover, in Vojtko topology, is covered with a coating that shields it from water; the grille has a surface treatment that preserves its shape through long exposure to damp; during assembly every point where the drive units attach to the front is sealed, to stop moisture getting in. The result is IP54 certification. The polypropylene cone with mineral filler and the titanium dome with ferrofluid remain those of the range.
Installation dimensions match those of the IC8: a round hole of 238 mm, 93 mm of depth, 8 mm standing proud and 264 mm of visible diameter. The locking clamps are worked by driving the screws and pull the frame tight to the ceiling; the cutting template is included. The micro-perforated grille can be painted and clings with magnets. The all-weather version has no square grille option; the pre-installation bracket is available separately.
