Know before you buy
The speaker requires a mounting depth of 4-1/4 inches. Ensure your ceiling cavity provides enough clearance to accommodate this depth along with the necessary wiring.
While the speaker is designed for easy installation, you will need to purchase the optional rough-in frames separately if you are installing these in a new construction project before the drywall is hung.
These speakers are designed to handle up to 100 watts of amplifier power. This provides plenty of headroom for clear, dynamic sound at various volume levels.
You will need to cut a hole with a diameter of 9-1/2 inches to properly fit the speaker housing.
The IS 8C utilizes an 8-inch titanium-laminate cone woofer and a 1-inch titanium-laminate dome tweeter. These materials are chosen for their rigidity and ability to produce clear, accurate audio across the frequency range.
The proprietary EOS (Elliptical Oblate Spheroidal) waveguide helps control the dispersion of high frequencies. This ensures that the sound is distributed evenly throughout the room, providing a wider and more consistent listening area.
