Know before you buy
Yes, both the grille and the frame are paintable, allowing you to blend the speaker seamlessly into your room's decor.
The STUDIO LS 328C is designed to work with amplifiers or AVRs providing up to 150 watts of power. With a sensitivity of 90dB, they are efficient enough to be driven easily by most standard home theater receivers.
You will need a mounting depth of at least 117 mm (4-5/8 inches) to accommodate the speaker housing.
These controls allow you to fine-tune the speaker's output based on your room's acoustics. You can adjust the high-frequency levels to suit your preference or compensate for sound reflections caused by placing the speaker near a corner or wall.
With an 8-inch aluminum woofer, these speakers offer a frequency response down to 28Hz, which provides significant bass for most music applications. However, for a dedicated home theater setup, adding a separate subwoofer is still recommended to handle the lowest cinematic frequencies.
The proprietary EOS waveguide technology helps distribute sound evenly across your listening area. This ensures that you get a consistent, high-quality audio experience regardless of where you are sitting in the room.
