Speaker stand spikes ~2” long?

 Hello Dentdog,

We currently machine a few critical parts for a product that may be the answer to all your needs for moving platforms, speakers and heavy racking about the room.

https://airsled.com/

Star Sound is designing adapters for the Air Sled® system allowing for all Sistrum, Rhythm and Timbre Platforms™ to match Air Sled requirements. You can move entire racks loaded with gear with a minimalist degree of human strength.

Currently we use two coupling discs, APCD4 and APCD5 to move multi-shelf racks, speaker and amplifier stands along with our newest compact monitor platforms throughout our sound environments. These have worked for some clients as well but are no match to the Air Sled’s ease of use standards.

Please give me a call if you are interested in any of these solutions. I have been away for the past two weeks due to self quarantine and will return to the office on Monday

Dentdog we have designed and added this new device to our solution portfolio..The APCD4 is a coupling floor disc or a point topper that wont tip over.

On the floor you maybe able to slide or angle the speaker into position. Have a friend help in balancing the speaker when moved. These devices help with fine tuning geometry and increase sonic performance. This is an incredible new part. Tom 

Thanks for all of the recommendations but I found out that Dyanaudio has a 2” XL spike that I can buy separately. 
Hopefully these work but I still would love to check out the Gaia II feet but have a hard time justifying the $800 price tag which is half the cost of my speakers. 
With the isoacoustics Gaia II’s I’d need the ones that hold around 100lbs as my speaker stands weigh 50-55lbs and my speakers weigh 40lbs. 

Tom, I have sets of Sistrum platforms and while I will say they had a positive effect under Zu Definition !V speakers, the ability to move the speakers became problematic. The platforms’ Audio Points were difficult to adjust for stability underneath the grates. So, looking for something more simple. Have numerous Audio Points with the platforms but the thread size precludes the use. Any ideas?
Have hardwood floors over concrete.

Funny guy, obviously you’ve never experienced super hard materials. What do you expect from someone who doesn’t think isolation is real?  It’s real and it’s spectacular! 

The super hard materials are to bright..they tend to make the soundstage crawl up the wall in front of the listener. All materials vibrate and the harder materials have a higher velocity and make the air vibrate faster which makes for more listening fatigue. A simple cone geometry allows for reflected energy to re enter into the system.Tom

The two primary variables for audio cones are material, size and shape. Oops, that’s three variables! The cones should be extremely hard, not like brass or aluminum or carbon fiber which are pretty low on the totem pole 🗿but like tempered steel and NASA grade ceramics. The cones should be ballistic shaped with the very best shape looking like the tip of an ICBM 🚀 Hey, I just described the Super DH (Diamond Hardness) Cone! The Jumbo DH Cone is the same ceramic materiel and the same size but not quite as ballistic in shape as the Super. And it’s performance is not quite as high as the Super but almost.

"A simple cone shape of just one primary angle allows energy to go down but will also some allow some energy to be reflected from the floor back into that singular geometry introducing interfering energy into the signal path. Tom"  

After much experiment I found this to be true. Now using solid cones to leather pads over suspended hardwood. For the sonics of my room, way better than threaded gliders or rubber feet.

For clearance here...I work with Starsound/Audiopoints..but I also have my own company Tone Acoustics. I started years ago to prove a point that this techology will work on most anything that touches the floor..cello and bass and bass clarinet for sure..anyway we use brass the metal of music. I am a fan of what we do. Tom

Tom, Thanks for this info. 
Have speakers with an aluminum base, down firing sub active in each. In looking for a good spike should I use aluminum? 

Any coupling point should be of 1 continious  run of the same material. To be made of more than one material shifts the tone, weight and acoustic transfer speed of the device. Almost as bad is the of use an adjustment nut which decouples the primary large conductive flange from either the speaker or the component. You are also altering the sound by introducing a disruptive shape made up of several right angles the worst sounding angle in existence a threaded Nut..A simple cone shape of just one primary angle allows energy to go down but will also some allow some energy to be reflected from the floor back into that singular geometry introducing interfering energy into the signal path.

I bought my 2" speaker spikes @ WWW.Speakerspikes.NET

Check out Eden Sound. Their stock X-Large spike is 1-5/8th inch...so it may not be 'tall' enough by itself. However, with their point receiver and locknut(s) you can probably get to 2 or more inches....should that solution work for you.

They may also be able to custom fabricate to your specs.

Audiopoints by Starsound have 2 inch Audiopoints you may need a metric thread..take 1 you have to a hardware store and ck the thread count and pitch. Tom

Thread is not correct for my stands. 
Plus is doesn’t say how long they are.
