Bass brace

Is there an issue with making the rod longer on the bass brace? My TV is 30" deep and up against the wall. I don't want to move the speakers back anymore. Currently they are 1" forward of the TV. That means the rod needs to be about 20" to reach the wall plate. Is this a waste of effort? I can use spikes, but getting hardwood floors next month and will have to remove them.

Thanks

    Priorities, or funding? Hahaha... Na, for the main room it's a 65" calibrated HD RPTV. So far haven't seen a plasma or LCD that matches or beats the image. Got true blacks, blacker than black, grey scale almost dead on and whites look like someone used bleach on the letters. Hahaha Now in the bedroom is a different story. Got a 26" LCD mounted on the wall for those last moments of TV/Movie before sleep and the days when I just can't seem to get out of bed.

    Wonder if I'd get in trouble for cutting out enough of the wall to set the TV back far enough so I can get my 1.2TLs 3" from the back wall. Of course I'd have to go outside and wall in the TV's back so it's protected. Na, too much work. Just gonna lay in bed and watch the LCD. :)

    Yeah, I went front projection with my SDAs so its all smooth across the front.

    Back on topic, I don't see why a longer bass brace would hurt at all.

    Okay, you never mentioned front projection! Now that I'm willing to do, but the cost is just too much right now. I've purchased too many goodies this year.

    I should go to my old company and borrow theirs. It sits idle 90% of the time. Can't remember the brand or model, but do remember it was about the size of a rooftop uhaul thingy and about the same shape. Only the lenses on one end made it recognizable as a projector. Hahaha

    I would still look into some type of spike/disc combo for the hardwood floor once it is installed. Finding what works best for your particular install may require some trial and error, but when you hit the one "best" result, it might be well worth the effort.

    The problem with having the SDA's that far out from the wall is you'll lose a lot of bass regardless if you use the brace or spikes. However, there's nothing that says you can't use a 20" rod.

    If you want some really nice spikes with matching discs so as not to scratch the new floor, look at http://www.myesound.com/products.html Be sure to order them with 1/4-20 thread.

    My understanding of the brace and spikes is that they are designed to reduce movement of the cabinet. Spikes on hardwood is a bad idea and wouldn't discs be useless on a wood floor? Nothing for them to grab onto.

    F1, do you remember my speakers? I think you mentioned the metal bar feet on them. Talked to the shop where they were originally purchased and they said they added them to stabilize them. They said there was two reasons for this. One, to give a larger footprint and reduce movement. Two, it's CA and earthquakes happen. They also said I could unscrew the discs from them and replace them with spikes.

    Yep, the bass is pretty weak where they are so far from the wall. Had to compensate with my PSW650. Not ideal, but it's the best I can do. Maybe it is time for a front projector.

    Thanks!

    The force on the rod is minimal. As far as strength you could use 20 to 30 inches with no problem. You would start having problems only when the center of the rod starts to sag. Actually, you could go much longer if you put a sleeve on the outside of the rod, but nothing like that would be necessary for 20 to 30 inches.

    On the contrary. Spikes with discs are primarily for use on uncarpeted floors. The disc simply protects the wood or other surface from the point. With the weight of the speaker on the disc it sort of becomes one with the floor and doesn't readily move.

    Tugboat,

    Yes, I do remember them. Since earthquakes are a concern I'd leave the metal bars on and use the brace.

    Okay, then looks for all the replies that since the braces on the bottom of my speakers have discs, I should be in good shape. Really should look into a front projector so I can move them closer to the back wall. :)

    Thanks all!
