Hello,
You should be able to use the OmniMount OM10 wall mount bracket. Or, any suitable wall mount bracket that uses a 0.25" diameter hole with a #20 thread to attach to the speaker.

Hello,
The threaded opening is very common in America, 1/4" diameter and 20 threads to the inch. I don't believe there will be a metric bolt that will fit it.
If you are unable to find this size speaker bracket try looking for a bracket that grips the speaker across the bottom, but because of the rounded sides of the enclosure make sure the speaker is secure.
The satellites are made of a type of synthetic marble material similar to Corian, this is done to make the enclosure rigid and inert. This will reduce unwanted cabinet resonances which can add coloration to the sound. Also the tweeter is recessed 1" behind the midrange driver. This is done to "time align" the two components and produce a more coherent sound quality.
Enjoy, Ken

wow...thank you Ken... you help me really...(maybe you know how much watts have speakers(satellites, center and subwoofer?))
hmm... sorry...cant understand about subwoofer a little..."Passive radiator:
10 passive radiator"?

A passive radiator is in essence a speaker cone with out the electromagnetic motor (magnet and voice coil) part of a regularspeaker driver. It is passive (not driven by the electrical input signal). Physically, it acts analogously to the 'port' on a bass reflex speaker enclosure.

Thanks, mhardy6647....I understand than subwoofer is pasyve... just interesting what inside sub box...and how it work... maybe someone have inside pics or something?

Hello,
The two 6.5" active drivers, in the sub-woofer, provide the changes in internal air pressure that cause the 10" passive radiator to function.

Thanks Ken...well I see its not traditional system of subwoofer... very interesting...maybe somewhere i can find scheme?
