Know before you buy

The SR9040 is sold as a single unit. While you can use one for specific setups, most home theater configurations require a pair to achieve balanced rear surround sound.
Yes, these speakers are designed to be compatible with most AV receivers and can be integrated into systems using other brands. Modern room correction software in your receiver will help calibrate the levels to ensure a cohesive sound profile across your entire setup.
These are wired speakers that connect via standard speaker wire. They are equipped with terminals that accept banana plugs, making the installation process straightforward and secure.
