Frequently Asked Questions - SAROS ICS8T-B-T-EACH Crestron
What is the difference between the 70V transformer taps and the 8 ohm bypass?
The SAROS ICS8T-B-T-EACH includes a 70V/100V transformer for distributed audio systems, allowing multiple speakers on a single amplifier channel. Set the tap selector to the desired wattage (60W, 30W, 15W, etc.) to match the system's power budget. For low-impedance operation, set the selector to 8 ohm bypass to directly connect to a conventional amplifier.
Can I paint the grille to match my ceiling?
Yes, the grille is constructed from perforated steel and is factory-primeable. Use any standard latex or oil-based paint. Remove the grille before painting, and ensure the perforations remain open by using a thin coat or painting from the rear side.
What ceiling cutout size is required?
The speaker requires a 250 mm (9.84 in) diameter cutout. It fits into ceiling thicknesses from 5 mm to 25 mm. Use the included C-ring and tile bridge for secure drywall or drop ceiling tile installation.
Is the subwoofer suitable for plenum rated spaces?
Yes, the back can is UL 2043 rated, making it compliant for installation in plenum air handling spaces where fire safety and smoke emission standards are required.
What amplifier power is recommended?
We recommend an amplifier delivering 150-240 W per channel into 8 ohms. In 70V mode, use a transformer tap that corresponds to about 10-20% headroom above the total continuous power requirement. For example, a 30W tap works well with a 30-40W amplifier allocation.
How should I position an in-ceiling subwoofer for best bass response?
For distributed bass, place the subwoofer near a corner or along a wall boundary to reinforce low frequencies. Avoid centering in the room. In dual subwoofer installations, place them on opposite sides of the room to minimize standing wave nulls.
Can this subwoofer be used outdoors?
The SAROS ICS8T-B-T-EACH is designed for indoor installations only. It is not rated for outdoor exposure. For outdoor applications, select a weatherproof Crestron speaker model.
What is the frequency response, and how does it integrate with satellite speakers?
This subwoofer covers a frequency range of 28 Hz to 120 Hz (±3 dB). In a distributed audio system, set the satellite speakers to crossover around 80-100 Hz, allowing the subwoofer to handle the deep bass and reducing distortion in smaller speakers.
How do I set the transformer taps correctly?
Determine the total wattage required by summing the taps of all speakers on the same speaker line. Select the transformer tap that is closest to the desired power level, never exceeding the amplifier's output. For example, on a 100W amplifier channel, tap at 30W for each of three speakers.
What maintenance is required?
The speaker is basically maintenance-free. Periodically dust the grille and wipe the frame with a dry microfiber cloth. Do not use solvents or wet cloths. Check the tile ring and dog-ear clamps annually to ensure secure mounting.
