    Yup. Got the original Polk stands too. All in mint shape. I've been playing with distance from the back wall. Probably about 6 inches right now. No toe in.

    Ah good. Spiking those stands helps as does mass loading them, which is a PITA to do, but worth it. In the rooms I've had my 4.1TL's set up, 5 inches from the back wall worked best, still not bass monsters though.

    I tried them about 2 feet away, and it was, lets say, not ideal. Then I placed them back against the wall (maybe an inch away?) and the bass came to life, but they were boomy. I'll try your 5 inch distance and let you know how that works. But 6 seems pretty nicely balanced.

    Btw, how the hell do you mass load the stands?

    It'll depend on the room and gear, so 6" might be perfect for you. Basically, 5" to 6" is ideal, so try 5.5" as well. That half inch can make or break it.

    You have to pry off the square plastic end caps, which is the PITA part as they do NOT want to come off. I suggest wrapping the metal around the caps with blue tape or the like, which will help prevent scratching the paint. I used a stiff putty knife and worked one side of the cap at a time going around all 4 sides gently prying. You have to do the two on top and the two on the bottom because the chambers are separate. Once you get the end caps off you can fill with lead shot or the like. I've got 22 lbs. of shot in each stand.

    Make sure you have the spikes or feet screwed in when filling and there are two small holes on the underside of the front bottom bar, seal those otherwise the shot will fall out.

    That's what she said!
    Good music, a good source, and good power can make SDA's sing. Tubes make them dance.

    That sounds like a fun way to spend a day! Did it really make a big difference?

    Sure enough, they weigh 22 lbs. more now. :cheesygrin:

    Seriously, I wouldn't call it a big difference more like subtle improvements to the bass and mid. It's one of those cumulative things.

    Sure, but it doesn't have anywhere near the mass of shot. Some folks mix the two, but I've never tried that. One thing with sand, it has to be desert dry.

    Ok.
    About what I figured.
    I'll add that to the list.
