I built that room out originally in 2006 at our lake home. That was in a built home, so there was reconstruct. The speakers I designed and built 2005 and 2006. Then we got a bit "long in the tooth" for lake life, and we built a home in the MSP suburb of Eagan 2018 to 2019. So I had a free hand to design the room. Uninstalling and reinstalling the equipment was a lot of work. Plus my wife wanted an in wall system in our great room, so I had to design and built that out, at speed. We also had to move the family room system from the lake home.
The only major addition in the move originally was the addition of four Atmos speakers.
The equipment now is pretty much as you see in the picture, but the Marantz 7705 has been replaced by an AV 10 and an old Marantz DVD/SACD player removed.
The back of the AV 10 installed.
Rear speaker wiring.
Front speaker wiring.
One of the things you have to pay special attention to is cable and Internet connection. So you need to be with the installer and make them do it properly, especially the grounding. They are industrial ground loop creators.
So you need an ethernet patch bay.
An Ethernet patch bay is in there. The cable modem is Arris. There is Cat 6 running to all fixed units. Only mobile devices connect wirelessly. All fixed units have Cat 6 Internet connections. There are two 19" Internet hubs in the studio racks, and local hubs in the other two systems and out office.
All cables in wall that are not accessible run in conduit, to allow for easy change of cables if required. No walls have to be opened up. It has worked very well.
There is equipment in the rig that spans over 60 years, most of which I have owned since new.
The speaker system is largely designed as Aperiodic transmission lines. In the main AV room, all the speakers are aperiodic TLs, except the surrounds and ceiling speakers which are sealed.
The rig even plays antique 78 rpm records, and the venerable Quad 22 preamp I bought in 1968 has all the right playback eq for the old 78 record brands.
Front of AV room showing right and left active triamped aperiodic transmission lines. Center biamped transmission line. It is a through wall design.
These speakers have active infinitely variable baffle step compensation allowing for optimal tuning of the speakers for their position in the room. This is something unique to this system, although JBL briefly copied it on a very costly system, they had to fly someone out to set up.
Rear TL speakers and sealed surrounds.
In wall Great room system with in wall transmission line sub.
2 channel family room system.
That is pretty much a synopsis of what we have here.
