MASS - Can It Realy Be That Easy To Upgrade?

[wesayso]

If I needed to increase volume to high levels to get imaging I'd be wondering if I was listening to reflections to get the image.

Grant.

That's a strange deduction. I never said that, did I? All I said is that I can up the volume and don't notice how loud it actually is. The volume is like a zoom button. Louder is closer, more quiet is further away. But it's more complicated than that due to our ears not being linear at all frequencies.
I actually like to feel my bass. For that you need output in the lower part of the frequency spectrum. My average listening levels are between 85 to 88 dB in my room. But louder was fun (but not that smart).

I'm not that worried about reflections as I actually know what I'm getting. (Selective) Room treatment is another great subject 😉.

But if you think of audio like this:

There is another way of thinking about this: the loudspeakers serve as the first "early reflections" of a (phantom) sound source whose direct sound we didn't hear. Because our brain is good at filling in the missing blanks, it "infers" where that phantom source must be and THAT "inference" is what we actually perceive, or think we "hear."

I'm definitely trying to get the best "reflections" I can 😀.

Just peruse his thread here and you'll have plenty! I warned you! 😉

Marble does not have a great shear strength and 1.5cm is actually very thin for marble. The guys i get my stuff of don't even like handling 2cm - you have to remember is is a sedimentary rock laid down in layers. They have a tendency to brake along these lines. Granite is igneous and has an interlinked crystalline structure which gives it far grater strength.

I am just worried that all your hard work could easily be ruined in the future by a small accident cracking one of the panels.

As far as the isolation goes - super bouncy balls rock. Literally. The one downer is the only place i can find them is a bubble gum type vending machine in the sea gardens. There are the super bouncy one that are great for this job and solid rubber ones that are US. The ratio of rubber to super is about 6 to 1 against - so i now have a huge collection of 1" solid rubber balls. Everyone who visits HAS to bounce the ***** and inevitably looses them. Then my dog keeps finding them and choking on them.

Oh, I can find those superballs very easily around here. I'll give it a shot.

About the thickness of the stone. The factory I am dealing with can cut marble and even onyx down to 0.6cm. They are one of the very few factories in the world that can do it. Everybody else want at least 2+cm...

I'm going to get a test box made of onyx cut at 0.6cm. Hopefully this Monday.

For strength, they usually back it up (epoxy) with plywood, honeycombed aluminium, or a combination of both.

They can cut onyx down to 1cm without backing to install a light and have it lit from the inside. Would never work with a speaker because of the stuffing, but still, a very cool effect.

Hi Stuck In Bulgaria, would you like to upload more photos, more photos of your modding and everything else? You've written a lot, and words + pictures is the best way to describe us mind.

The balls are not necessarily well damped, they deform and return to their shape so they will be allowing the cabinet to move. The one thing that mass loading on the top of the cabinet, and these balls, seem to have in common is they alter the interaction of your cabinet with the floor.

Here's a prototype I got.

It is onyx, cut at 0.6cm, backed with a 0.8cm plywood. Beveled edges on all sides.

Total weight of one cabinet, without the wood baffle and driver is 8.7kg.

It is simply gorgeous.
