This is a great sounding unit less than a year old, but it's time to downsize.
I'm posting many images to get a good idea of what I did.
I mounted the satellite speakers and built an enclosure for it.
Everything you see is included even the straps for the subwoofer which I covered with speaker cloth.
I paid $234.00 for the speakers. The price is open. If anyone is interested please email me at:
greatmusic@comcast.net and we can talk about it. It's not heavy at all and very sturdy and transportable.
I forgot to show the remote. That's include too.
Thanks, Peter

I have the z5500s already, but like the work you did with D connector and the wiring harness, nice neat setup.

I use a set-up almost identical to your number 3 photo except that I have the cross beam mounted on a standard speaker stand which can be height adjusted to suit the venue
