It was recently used in my living room (connected to an ONKYO TX-L50 amplifier).

When I removed it and tried to move it after a long time, I heard a rattling sound inside whenever I tilted it, as if something was rolling around. I always used it placed on the floor, so perhaps small screws or something entered through the woofer's opening, or a small internal part has come loose...? The rattling sound doesn't occur when it's stationary, and the sound output is normal. However, please refrain from purchasing if this is a concern for you.

I will include a relatively long RCA cable (around 2m?).

As shown in the photos, one of the rubber seals on the front right leg out of the four has come off. It does not wobble when placed flat.

It is in working condition, but there are minor scratches and dirt consistent with its age.

Please understand that this is a used item.
