    Default RTi4 Ceiling Mount

    I'm just wondering if anyone has used Omnimount 20s to mount RTi4s? I've done a search here and not come up with any hits. I've seen the BTech B77 mentioned and it looks like an elegant solution, but given the requirement of a stud, I'm not sure they'll work for me. Also, they're not available in white, but that could probably be solved with some spray paint. I had my previous surrounds (Rocket ELT LRS) mounted via the Omnimounts and also have 2x4s in the ceiling for that purpose, but in order to do so, I had to drill into the base of the speaker about 1/2" to secure the brackets. Polk tech support says no more than a 1/2", so to me that's cutting it a bit close. It would be good to know if someone else has went this route successfully. The keyhole mount isn't really an option for my either. Thanks for any help with this.

    I have RTI4s ceiling mounted with the Omnimount 20.0s

    In my HT setup, I'm in a mid-sized family room with the couch all the way up against the back wall -and the family room is open on the left side to the kitchen.

    Therefore, I could not:
    1) put the surrounds 'behind' the listening area (the couch)
    2) put the surrounds to the left and right side of the couch (because there is no side wall on the left since it is open to the kitchen)

    My solution was to ceiling mount the RTI4s directly over the couch separated by about 10 ft and angle them down and towards the couch (but not directly AT the listening spot).

    I actually used the wall mount kit for the Omnimount (the straight ball adapter, not the "L") and connected to the back of the keyhole plate on the back of the RTI4s. I spread the load on the plate by using two large washers, inserting the thread post of the straight ball adapter, and threading on the nut and tightening it down.

    The Omnimount base plate was then installed to the ceiling and I adjusted the angle of RTI4s so that one bottom corner of each RTI4 touches the back wall - just to relieve some of the stress of the mount holding all the weight of the RTI4.

    Kinda hard to visualize from my description - I'll try to snap a picture this weekend.

    It is working really well and is secure - I'm happy.

    Just a clarification on how I attached the Omnimount to the back of the RTI4...

    The Omnimount kit comes with two nuts that thread onto either the straight post and ball (for wall mounting- which I used for ceiling mounting), or onto the "L" post and ball (for ceiling mounting)

    I used both nuts for each RTI4: one on the back of the keyhole plate with a large washer and the second nut with washer on the other side of the keyhole plate.

    I tightened both down at the same time (from opposite sides of the keyhole plate). Very snug, very secure - and the keyhole plate is already designed to hold up the weight of the RTI4s. So this allowed me to use the mount without drilling holes into the RTI4 cabinet.

    FWIW,
    Erik

    Thanks for the info. I was using the straight mounts instead of the L as well. I hadn't thought of using the keyhole bracket with it though. I'll give it a look over the weekend. I also contacted Polk support again and found out the cabinet is 3/4" thick, so if I do drill in, there's no way I'll go through. The BT77 isn't out of the running yet either. I was talking to a guy at my studio that does installations on the side and he thought that my walls would be able to support that mount w/o using a stud by using anchor bolts. My apartment walls are sheet rock on a metal frame. I'll post the solution I decide on and how it works out once I get it done, but it won't be for a couple of weeks. (new ceiling going in) Thanks again!

    Well I got the RTi4s mounted today, so I figured I'd post the solution. After tech support strongly discouraged using the keyhole mount as ET did, I elected to drill into the cabinets to attach the bracket for the Omnimount 20. I flipped the RTi4s and attached the bracket to the bottom of the speaker, just in case I ever use them for something else. That way, the ugliness will be out of sight. Also, the mounting screws did not penetrate all the way into the RTi4's enclosure. As an alternative, I also purchased the BT77s, but given a comparison of appearances, my wife shot them down. Interestlingly enough, they actually would have required me to put more holes in the RTi4s than the OMs did (5 vs. 2). Nice mounts, but they'll be heading back to Crutchfield next week.
