Blu Tack. Requested link... Blu Tack - Wikipedia available at your local hardware store. I recall a well known high end speaker manufacturer (which I can't remember) praising its use as a cabinet stabiliser/isolator
cheap stereo in-wall speaker volume control as stepped autoformer volume control between CD player, etc, and amplifier. Some have RCA jacks. I think most op amps can drive such a load and not roll off much on the bottom nor be damaged (?)
also, filament transformers arranged so the low voltage winding is in series with a loudspeaker, and mains voltage controlled with a pot. That makes something I believe like Decware's "Gizmo" and could be fun for experimentation.

In my student days my whole flat was furnished with scavenged items , concrete blocks for speaker stands , housebricks and scaffold planking for equipment racking and
bookshelfs , wood pallets made excellent bases for beds and seating and my pride and joy was a coffee table , one of those huge wooden spools that British Telecom stored cable on , sanded and stained .
Nowadays you would pay through the nose for any of the above sold in trendy ' lifestyle '
and reclaimed furniture stores.
Some years ago a friend and i built a few speakers using concrete , he was a designer for a kit car manufacturer and was pretty good at making moulds .
Started with some small conical ' bookshelfs ' using car co-ax drivers which sounded surprisingly good then a couple of bigger units with proper full range cones .
Concrete does appear to be a pretty inert and dead material, we were working on a floorstanding TL design but unfortunately he lost his life in a motorcycle accident
( R.I.P. Matt ) so it never developed beyond a cardboard model , one day i may pick it up again.
Someone mentioned platforms with inner tube suspension , great cheap and effective mod that the obsessive tweakers can also employ and spend endless hours experimenting with the ideal psi for each individual component. 🙂
There are a few companies making concrete based speakers , a Swedish manufacturer MOONLIT , AX HORN in Wales and the N1 's by Concrete Audio to name a few.

Locating the turntable in a corner also helps. I used to use K-horns that would cause feedback with the turntable until I put it's little table in the corner.
Cheaper tip: steal playground sand from playgrounds. 😛
Sift it first!
I wouldn't do that even if you paid me. One cat with worms taking a dump on an afternoon and you've got a possible brain damaged audiophile.
Also works great with sealing the surround of speaker baskets when installing new speakers in cars. It does solidify after a while though as the moisture evaporates from the blu track.

Rub crayons into the pointer grove or dot on knobs to add or change the color
Note only works on some knobs

I've not had that problem, reused it after 20years under a speaker cab, how long are you talking about?
Might be a regional thing. it is pretty hot here in aus. takes about a year for blu tack to turn solid here unless you keep it wrapped up.
For posters blu-tack is completely useless. Many a night I have been woken up by a massive crash in the bedroom only to find out that it was simply a poster falling to the ground.
It sure scares the big jesus out of you.
Thumb tacks work great.

I buy , or used to, a lot of used speakers and i keep a pack of crayons for concealing small scratches and marks in the cabs .
There's normally a colour that will match most finishes , just fill in the the damaged area and blend it in with a finger , don't use a cloth though it will just wipe the crayon off again.
A use blu - tac a lot but it can stick like superglue in some cases.
I had a small pair of speakers de-coupled from the stands once that after a few years were stuck so firm that when i attempted to remove the speaker came away but left it's vinyl wrap behind !!!
I read of someone using upturned egg cartons as “cable elevators”, but you will have to decide for yourselves whether this meets the “that work” criterion.

Duct-seal might be a good substitute. Our climate is likely wetter than yours (at least in winter), but i have reused 25-year old duct-seal. Probably cheaper than blu-tak as well.

Now there is an idea. and a Bunnings Warehouse is nearby so I could easily get some.
Thanks for the tip.

These days I don't find anything I would take home unless it had someone running an estate sale and such because they know there is something worth a bean.
I love yard sales. I have paid from $0 (given to me free because I bought something else) right up to $125 for a pair of Klipsch Forte's in mint condition. Everything in between also. They feed my addiction. 🙂
