Q: Does the product depth of 10.2” include binding posts or just speaker.

A: Hello. Thank you for your question and we hope all is well. We apologize as it looks like the depth spec on Best Buy's website of 10.5 is a rounded number. For more precise measurements, the depth of the Motion 30i with the grill on is 10.81. This dimension includes the binding post. Thank you for your interest in our products and we greatly appreciate your support.

Q: At least how many inches from sheetrock wall would this speaker need to vent since it is ported? I would have 3” of space.

A: You can have it as close as you want (within reason). Being closer will just make the bass more boomy. About 8-12" away should be good. Some may say 12-24 inches, but around 12 ive found is good.

Q: Can this speaker still be purchased in the cherry walnut color? I have the old version of the motion 40s in that color and I was wondering if the motion 30i could still be purchased in that color scheme?

A: Hello. Thank you for your question and we hope all is well. We make the Motion 30i in a red walnut, but the finish is different than the gloss black cherrywood. There is also no gloss to the red walnut on the Motion 30i like the Motion 30 or your older Motion 40s. If you're interested, we would recommend reaching out to your local store for stock availability. They may also have the red walnut finish in stock for you to compare in person. Please let us know if there is anything else we can help you with and thank you for your support.

Q: Can this be mounted to a wall via a bracket?

A: This particular center channel was not designed to be mounted on a wall, as there are no threaded mounting screws to utilize. However, there are clamp-style brackets that may work to mount this to a wall.

Q: How many watts in the speaker??

A: This speaker is passive, having no amplifier of its own. However, it can handle from 20 to 200 watts.
