In Reply to: RE: Bright star sand box posted by stator_99@yahoo.com on June 18, 2021 at 13:44:59
Tried Brightstar big and little rocks over the years, and frankly, when component is in contact with thin panel directly on sand, music sounds overdamped and dead.
Little rocks have no opening and sand does not fill all the way to top. These sound much better to me in right doses under certain gear (transport, etc). They also really improve subwoofers on top of the sub.
Follow Ups:
Regardless of which racks I used them, the Bright Star Audio Big Rocks made each and every component sound slow, dull, airless, and lifeless. OTOH, a few Stereotypical Audiophiles liked this type of sound, and used euphemisms like "smooth," "relaxing," and "stable." So, like everything else, you just have to listen, and judge for yourself.
Also note that the top is not sealed. Bits of sand can escape, in the gap between the box and the top panel. Because I didn't find the Big Rock to have any positives, I never did try to DIY one.
The sealed Little Rock, however, could effect some positives. In general, when placed on top of a comment, the smaller sizes worked better. When we used the heavier/larger Little Rocks, they could squeeze the life and air out of the music.
Interestingly, we found that the larger Little Rock did well as a base . Even under something like the modest Audio Alchemy DDE v1.0 DAC, the Little Rock used as a base removed some sonic fizz, grain, and instability.
This reminds me of experiments friends and I performed with bags of sand and lead shot way back in the day (mid-to-late 90's), placing them on top of loudspeakers and especially subwoofers. We used 5 and 10 lb. bags (depending on the size of the speaker) with good success. A really inexpensive tweak that yielded sizeable sonic benefits.
Physics didn't change....all of us went on to explore different ideas and forgot some of the basics. This thread is a good reminder....
I experimented with lead weight on speakers some years ago.
I went to an automobile tire store and asked for tire weights. They offered a five gallon bucket of used weights, which I took. Tire weights have a steel clip on them that is used to attach the lead weight to the wheel. However, weight is weight, and the price for used weights was right - free!
I was cautioned at the time, that used weights can accumulate numerous toxic chemicals. I used rubber gloves and metal trowels to shovel the weights into doubled freezer Zip-loc bags. One could measure the bag weights on a scale and have each bag weigh a specific amount, if so desired.
It is important that one seals these used weights in air tight containers as there are noxious fumes tha emenate from the used weights. As I write this, I thought of placing the weights in cake tins (like what fruit cake comes in). Alternative solutions may have to be employed if the weights are to be used in a sandbox.
Used tire weights may be free or at minimal expense. YMMV

We purchased the lead shot at a local gun store. It came in a canvas bag, so easy to carry, easy to place. I remember two differing sizes/weights, like 5 lbs. and 10 lbs.
And implementing them was super-simple, as was the A--B--A test: play a track, plop them onto the subwoofer, then remove. We could hear the differences quickly and easily.
Now you'll pay 50 bucks for 25 lbs., unless you live in the CSSR where you can't buy it at all.
That's $100 for a decently audible tweak. Fairy Dust Fuses cost as much. Why would anyone fuck around with those used tire weights is beyond me. If you're that cheap get your kid's fat cousin to come sit on your original AR3's.
There's no virtue in being old,
it just takes a long time
Have you priced lead shot lately, Alan?
Not the inexpensive tweak it used to be.
I went to my local Menards home improvement store today to purchase some 10 gauge romex for a dedicated circuit for my Audioquest Niagra 9000, boy have copper prices went up!glad I only needed a 25 foot roll.
I had a feeling it probably skyrocketed. Lumber, steel, and other basics have done so the last couple of years. Rare earth metals (especially those used for plating) have gone crazy.
