adding a subwoofer to my 2 channel lanai system

Just thought of another issue, it will be important to choose a woofer with the same sensitivity of the other in-ceiling speakers, although a 1db difference will likely not matter.

Tls49, the living room speakers are 6 ohms. I'm using a powered REL sub with a pair of Monitor Audio GR20's.

SpeakerCraft reviews are depressing at best.

I realize that putting a sub in the ceiling is not going to be revolutionary, I'm just trying to add a little bass to my lanai listening.

Since living room speakers are 6 ohm with a powered sub, impedance will not be a problem.

As far as the SpeakerCraft and OEM Systems, these were just shown as examples of how to properly do what you were asking.

Another option would be a ceiling mounted woofer with an external subwoofer amp like these,

ICS11 Ceiling Subwoofer

M3 Subwoofer Amplifier

The subwoofer amp will need to connect to the MA6500's L&R pre out.

Thanks Tls49, I will definitely look into your
Recommendations. Thanks again for your help.
