Surround Shelf Plans....

edited August 2004 in Speakers
I have took a shot at designing a shelf that can support the weight of the BP6B on my wall.

The challenge was, there are no studs. So ---- The idea I have here is to use the PVC pipe on my wall already which is up on top of the baseboard, so I hope to put all the weight of the shelf on to the PVC pipe (and of course putting about 10-16 screws into the shelf into the wall.)

Anyway, here is the design...

I had to break it down for the forum to see..

    Sid,

    They make these neat little drywall anchors for stuff like that. You screw it into the wall and it basically threads itself into the drywall. Good for about 50 lbs. per anchor they say, I haven't personally tested that, but they should be the trick (four of them per).

    Your over-complicating it. Think simple, dude.

    Well the shelf is a matter of need more than holding it on the wall...

    The PVC isnt coming down, I don't have any paint left over from my remodel job and I would have to repaint where I detach the PVC pipe.

    So I need to cover that up since these are towers.

    Also, I want to hide the screw hole where I had the RT35i on...

    So I might use the anchors u mentioned to put the shelf on the wall. The shelf is more cosmetic issues than holding stuff.

    See what I mean...

    The shelf top will go to about where the power port is on the RT35i, and will go down 22.75" down the pvc pipe...

    Gotta hide stuff...

    the shelves arnt costing me anything either, I agreed to wash the guys huge truck in trade for them...so, size/materials arnt really a thought

    Are you talking about a shelf to support floorstanding speakers? If so, that's ridiculous.....

    If it's a bookshelf, ok fine.......but amulford's right......keep it simple....sheesh

    I wouldn't do it unless you can hit atleast two studs. Make the back wider if necessary.

    If you're gonna try mounting these to just sheetrock be careful to not use to many screws. Not enough and they'll rip out, but too many and it will make a perforated line and pull out that section of drywall with it. Atlest then you would have access to the studs and could mount some horizontals before patching the wall.


    Good luck and put something soft under those speakers.

    I figured I would use about 3 screws per side, should be more than enough. I was gonna use sheatrock anchors --

    And with the PVC pipe helping it, it should work - I would think. 50 pounds aint that heavy...

    thank ya for the advice!

    Should have some stands by next week I hope....

    PVC piping on the back of that shelf will provide ZERO support for that shelf. It's aesthetic, that's it.

    how far up on the wall are you putting these things anyway? What's the problem with keeping a FLOORstander on the FLOOR?????

    And where do you suggest I put them brett?

    They are my surround speakers...

    I guess I could set it on top of my bed and lean em against the wall! and the other could go on top of my desk...hmmm

    I think I'll stil to surround shelfs...lol

    no matter how retarded yall think it is.

    I could actually probally hit 1 stud --

    The PVC pipe is about 12-13 inches from the corner, which would mean 4 inches or so over would be a stud....

    I dunno, will have to see...

    It's not when spread out over enough area. A bigger concern would be the vibrations. Each screw is gonna be a mini jack-hammer pounding away at the sheetrock. Maybe if you included a pair of legs on the front to take the weight. What is that PVC connected to?

    Are these for bi-polar towers? Seems like defeating the purpose.

    They are surrounds. I just want to put them in use isntead of them collecting dust.

    The PVC is held in with 8 screws ---

    The vibrations shouldnt be to bad.

    I don't watch that many movies, and surrounds don't get that much action during a movie... so not sure man....

    Only way I can tell is try it and test them before I put the speakers up there. Worst comes to worst, I can take it down and patch up my wall and forget it...

    Legs on the front might be an idea, but the problem with that would be my bed is below one, and my desk is below the other....

    I dunno, I have no idea how my house was built. There are several possibilities with how these things will/can mount.

    If it was built on center, 16" apart in the studs + 1 stud per wall, and depending on where they put THAT stud -- I could have a stud to nail into on one side closer to the corner of the room. If they did it 16" on center, it could VERY well have one right at the edge of one stand that I can screw into....

    Will have to try it out and see...

    Just make the back wide enough to hit the studs. It doesn't have to be the same size as the speaker.

    Even if the front legs were just at a 45 deg and anchored to the same wall, you would be dispersing the weight a little more.

    That's what you said when I asked if we were talking about a bookshelf or floorstanding speaker.....

    Surrounds going up on shelves aren't a big deal......You just need to mention what you're trying to deal with from the beginning......I personally have no idea what a BP6B is. He's not talking about a support going from the shelf to the floor....it'd be from the front edge to 6inches or so below the shelf against the wall to prop it up basically.

    Good luck with it.......

    They are bi-polar floor standing surrounds.


    Sid - Build the shelves to fit the corners. Added strength and you'll probably get better effects of the bi-polar (unless you were thinking about mounting them 90deg off-axis) effects.

    I agree, the pipe is useless, and cutting out the back to accommodate the pipe just weakens the structure.

    The way you have the bottom shelf attached with the 2 triangle pieces, will transfer the load to the back of the shelf. So make the length of the back the same as the height of the speaker, to distribute the load. Anchor the back to the wall with at least four screws (2 at top, 2 at bottom), use more to fill in the length of the back every 16 inches.

    But supporting 50lbs with sheetrock only, may be a bit too much.

    if it's not too late,..

    if you can hit one stud you're in, even if the shelf is not centered on the stud.

    use 1/4" lag bolts and washers. long enough for 2" of bite into the stud (so if the shelf back is 1 1/2", drywall 1/2" + 2" bite= 4" lag). 3 for each shelf. one through each of the 3 horizontal cross members. predrill through the shelf just larger than the lag, so lag will slip through without forcing it. predrill the wall the thickness of the meat of the lag, so only the threads bite the stud. if want the lag heads flush you can predrill the shelf the size of the washer deep enough for the head to be flush.

    you can use a 3" drywall screw through one of the predrilled holes in the shelf to temporarily hold the shelf while you predrill the wall on the rest.

    you could probably get by with deck screws (the type that look like drywalls) instead of lags too, but, i know you're a heavy duty kind of guy.

    GOOD NEWS....AND BAD NEWS!!!!


    ARE YOU READY???
























    GOOD NEWS -

    WE FOUND STUDS








    are you ready for the bad???



















    I WASTED 10 bucks on dry-wall anchor/screws

    We found some of the WEIRDEST measurements, studs were like 14 inches apart... @_@ WTS?

    Anyway.... thank you all for your discouragement and encouragement.

    My room is surrounded by towers and I love it!

    I'll post some blurry pics for you folks next weekend when I go back to my Dad's.
