It lacked a riving knife with no way of adding one. Plus the saw had poor dust collection and lacked the power to rip 8/4 hardwood.

I see, I'm not a pro, but I'm hoping the R4512 would work for my needs.

Riving knife is a safety feature that helps prevent the wood getting pinched and kicking back at you. You should ONLY buy a table saw if it has a riving knife.

Interesting, I thought the RF4512 had that feature, anti-kickback.

The ridge at anti-kick back might be claws that grab the wood. The guard over the blade might have a riving knife but a true riving knife is also there when there is no guard on the saw.

I see makes sense, maybe looking at a different saw than you had, the R4512 has a riving blade on it.

Page 26, It's part of the main assembly, not attached to the guard etc. Sorry for the confusion!

Yep this is a newer model that has a true riving knife and better dust collection. Good luck and be safe

Any updates Greg? I'm interested in your opinion on the 7702 for sure as I might sell my Yamaha Pre/Pro to support the new Atmos format. What Amp did you purchase I see the Outlaw box so I have to assume that is what you are going to use? I have a Parasound A31 for my front three and looking at options for the balance of the 8 other speakers to run a 7.2.4 setup. Much to consider for sure. Looking forward to your updates as I'm following you lead moving forward.

Had a minor set back last week. One of the Polk LS-700 had a crossover short. So it took the better part of the week to get the RMA and then return the speaker and get a new one. I get very fast shipping from Polk. If I order by noon I will get it the next day by 2PM. But it still took 5 days

I used the Outlaw 7700. I wanted to use the Marantz power amp but it dose not support 4ohm speakers. All my original 5.2 Polk LSi speakers are 4ohm.

The ceiling speakers are channeled through the old Sony receiver using the 5.1 inputs. The ceiling speakers were not part of the original plan. The plan was just replace an 14 year old Sony receiver, get Dolby TrueHD and add the rear channels for 7.2. Atmos was just a bonus.

I have done several equalization run througs and we have watched one Atmos enabled movie and one non-Atmos movie. The most encouraging thing was my wife commented on how much BETTER the theater sounded.

I also bought the Marantz blu-ray player to get an integrated WiFi remote control on my iPad mini, which is so much better then IR.

The front L/R, center, surrounds L/R, and Rear L/R all connect to the seven chanels in the Outlaw 7700 using the balanced connection and XLR cables.

The ceiling channels Front High L/R and the Rear High L/R all connect to the old Sony receiver using the 5.1 inputs. So here I used the RCA out from the Pre amp to the front L/R and the surrounds L/R of he 5.1 inputs of the Sony receiver. I run the Sony receiver at 50 volume and use the pre amp to control the volume for all the channels. So the Sony receiver is being used as a power amp for the ceiling channels.

Everything is processed by the AV7702. The Bluray audio comes across an HDMI cable to the AV7702. All the pre-outputs, from the AV7702, go to either the Outlaw 7700 or the old Sony. The Sony receiver is just being used a a power amp, just like the Outlaw 7700. Eventually the sony receiver will be replaced by an outlaw 7500 (five channel power amp).

So if you do not want to build all the wood frames look at plastic track systems

Are you using anything like Owens Corning 703/705 ?

Yes Linacoustic® by Johns Manville. It came in a 4 foot by 100 feet roll. AT first I was going to use the Corning 703. T sourced the 703 through my local Home Depot but a few months later when I went back to buy it HD no longer sold the Corning 703..

Being in a roll, is as rigid as the 703 ? I have young kids and I don't want them pushing in the fabric and messing it up.

it is not as rigid.

I have 4 grand kids that have all grown up with the theater. The oldest is 11 now. But even when there were very young, we never had any problems.
