This temporary sound-support structure combines one approximately 12m-high steel Ringlock main tower with three approximately 2m-high auxiliary base modules arranged around the lower part of the main structure.
Its geometry is therefore fundamentally different from a conventional four-leg tower.
The complete concept is:
1 × 12m Main Ringlock Tower
3 × 2m Auxiliary Base Modules
1 × 2.5m Aluminum Top Truss
Manual Hoist & Rigging Interface
The confirmed BOQ contains 10 adjustable base positions, which reflects the expanded ground-level arrangement created by the main tower and its three auxiliary modules. It also contains 63 horizontal pipes, 46 diagonal pipes and 36 vertical pillars.
For DragonStructure, its primary classification should be:
Sound Support Structure
https://www.dragonstructure.com/Sound-Support-Structure-pl08155276.html
This registered category is intended specifically for sound-support structures, PA towers, line-array support and Ringlock sound towers.

Dragon Stage
The original DragonTruss product calls it:
12m Sound Speaker Steel Ringlock Delay Towers
For DragonStructure, that name does not explain enough about the structure itself.
This is better understood as an asymmetrical multi-base Ringlock speaker support tower:
one tall central/main structural zone;
three short auxiliary structural zones;
ten ground support positions;
an aluminum top truss;
a manual hoisting interface.
The key structural characteristic is not simply its 12m height.
It is:
A 12m main Ringlock tower rising from an expanded lower structure formed by three additional 2m-high auxiliary base modules.
That lower arrangement is the feature that separates this product from the other Ringlock sound towers.
The structure is configured as a temporary elevated support position for concert/event sound equipment.
Item | Configuration |
|---|---|
Primary Function | Sound / Speaker Support |
Main Structural System | Steel Ringlock |
Main Tower | 1 |
Main Tower Height | Approx. 12m |
Auxiliary Base Modules | 3 |
Auxiliary Module Height | Approx. 2m |
Adjustable Base Positions | 10 |
Top Truss | CS40 aluminum square truss |
Top Truss Size | 389 × 389 × 2500mm |
Hoisting Component | Manual Hoist |
Primary Application | Concert / Event Sound Support |
The Ringlock system creates the tower and expanded base configuration.
The aluminum truss and hoisting components create the interface associated with the elevated speaker-support position.
The simplest way to understand this structure is to divide it vertically.
This is the widest and most component-intensive part of the configuration.
It contains:
Main Tower Base
Auxiliary Base Module 1
Auxiliary Base Module 2
Auxiliary Base Module 3
This lower zone creates the confirmed 10 adjustable-base positions.
Above approximately 2m, the three auxiliary modules stop.
Only the main Ringlock tower continues upward:
2m → 4m → 6m → 8m → 10m → 12m
At the upper end of the tower, the BOQ includes:
2.5m CS40 Aluminum Square Truss
Manual Hoist
Fibre Sling
Double Clamps
This forms the equipment-support interface supplied with this particular configuration.
The BOQ contains:
10 × Adjustable Base LR4, H: 0.25m.
This is one of the strongest clues to the actual geometry.
A simple four-corner tower would suggest four ground positions.
This configuration has ten.
The practical reason is that the ground structure extends beyond the main tower through three additional 2m-high auxiliary base modules.
So the base count is not an incidental BOQ detail. It helps explain the overall configuration:
Main Tower
Three Auxiliary Base Zones
→
Expanded 10-position ground arrangement
This is also why describing the product only as a “12m Ringlock tower” loses important structural information.
The main vertical structure reaches approximately 12m.
The BOQ uses:
2m Ringlock vertical pillars
so the tower is created through repeated modular levels rather than through one continuous fabricated column.
Conceptually:

Top Speaker-Support Interface
The confirmed BOQ contains 36 × Pillar LR1, L: 2m distributed through the complete structure, including the main tower and lower auxiliary modules.
The BOQ does not assign individual pillars to each module, so those quantities should not be artificially divided into “main tower quantity” and “auxiliary tower quantity.”
This is the defining feature of this product.
There are:
3 auxiliary modules
and each rises only approximately:
2m
They should therefore not be interpreted as three additional 12m speaker towers.
Their configuration belongs to the lower support zone of the main structure.
The vertical relationship is:
Main Tower: 12m
Auxiliary Module 1: 2m
Auxiliary Module 2: 2m
Auxiliary Module 3: 2m
So after the first 2m structural level:
all four structural zones exist at the bottom;
the three auxiliary modules stop;
the main tower continues upward another approximately 10m.
This creates a very different silhouette and ground arrangement from a simple rectangular tower.
These sound-support structures should not be differentiated only by height.
Their base architecture is also different.
Structure | Main Tower | Auxiliary Modules | Auxiliary Height | Confirmed Base Positions |
|---|---|---|---|---|
8m Configuration | 1 × 8m | 1 | 2m | 6 |
This 12m Configuration | 1 × 12m | 3 | 2m | 10 |
Earlier 16m Configuration | 1 × 16m | 2 | 4m | Different configuration |
Therefore, the product family is better understood as:
8m tower:
Main Tower + Single Low Auxiliary Base
12m tower:
Main Tower + Three Low Auxiliary Bases
16m tower:
Main Tower + Twin Taller Auxiliary Structures
The height changes, but more importantly, the lower support geometry changes with it.
That makes these legitimate separate Structure Products rather than near-duplicate pages distinguished only by 8m / 12m / 16m keywords.
The BOQ confirms:
36 × Pillar LR1, L: 2m.
These standards create the vertical grid throughout:
the 12m main tower;
the three 2m auxiliary base modules.
Their 2m modular length corresponds naturally with the repeated height levels visible in this type of Ringlock configuration.
The important point for structural understanding is that the 12m tower is modular, not a single fabricated steel mast.
The BOQ contains:
63 × Horizontal Pipe LR2, L: 2m.
These horizontal members connect the vertical standards and establish the Ringlock bays.
The basic structural system can therefore be read as:
Vertical Standards
Horizontal Ledgers
→
Three-Dimensional Ringlock Grid
Because the bottom 2m contains the main tower plus three auxiliary modules, more horizontal connections are required there than would be suggested by looking only at the tall central tower.
The confirmed BOQ includes:
46 × Diagonal Pipe LR3, L: 2.44m.
These diagonal members brace selected Ringlock bays throughout the configuration.
At structural-breakdown level:
Standards + Ledgers
create the modular frame.
Diagonal Members
create the braced bays within that frame.
The quantity and arrangement belong to this confirmed configuration, but they should not be converted into an unsupported claim about:
allowable lateral load;
wind resistance;
overturning resistance;
maximum suspended speaker weight.
Those questions require project-specific verification.
The BOQ separately lists:
2 × Steel Braces, L: 2m, H: 0.5m.
These should be kept separate from the 46 Ringlock diagonal pipes because the source treats them as a distinct component type.
They belong to the supplied sound-tower package, but the available BOQ does not provide enough information to claim a specific calculated structural function beyond their use as part of the configured support assembly.
Unlike the previous 8m configuration, this BOQ explicitly contains the upper aluminum truss.
The confirmed component is:
1 × CS40 Square Truss
389 × 389 × 2500mm
This is an important distinction.
The structure is therefore not purely Ringlock from ground to equipment interface.
It combines:
Steel Ringlock Tower
↓
Upper Aluminum Square Truss
↓
Speaker-Hoisting Interface
This is a functional material integration: Ringlock creates the main temporary tower, while the aluminum truss forms part of the upper sound-equipment support arrangement.
Because the primary function remains sound support, I would still place the page under Sound Support Structure, rather than moving it primarily into Hybrid Structure.
The BOQ includes:
1 × Manual Hoist, T1
1 × Fibre Sling, T4
This is another important difference from the preceding 8m product.
The supplied configuration does not stop at the Ringlock frame. It includes components associated with lifting and connecting the sound equipment to the upper structural zone.
Conceptually:
12m Ringlock Tower
↓
2.5m Aluminum Top Truss
↓
Manual Hoist / Sling Interface
↓
Speaker / Line-Array Equipment
However, the labels T1 and T4 should be preserved as source specifications. They should not be rewritten as verified 1-ton and 4-ton capacities unless the manufacturer's component data confirms that interpretation.
The confirmed BOQ includes:
4 × Double Clamps.
These clamps are part of the interface between the tower/top-truss arrangement.
Their presence is useful because it shows that the aluminum top truss is not merely an unrelated accessory packed with the system.
It belongs to the upper integration of the complete sound-support configuration.
Exact connection orientation should follow the actual drawing and assembly configuration rather than being reconstructed from the BOQ alone.

The BOQ is especially useful because it explains why this tower should not be treated as a generic 12m scaffold.
The key numbers are:
36 vertical standards
63 horizontal members
46 diagonal members
10 adjustable bases
The 10-base count is particularly informative.
Combined with the confirmed project configuration, it reflects a lower structure composed of:
one main tower base
three auxiliary base modules
The BOQ therefore tells us something that the original commercial title does not:
The structure becomes much wider and more interconnected at ground level than the upper 12m tower alone suggests.
That is exactly the type of structural information DragonStructure should expose.
A useful way to read the structure is:
Main Tower + Three Auxiliary Modules
This is the expanded base zone.
Main Tower Only
This is the tall vertical zone.
Aluminum Truss + Hoisting Interface
This is the sound-equipment integration zone.
So the complete structure has three functional layers:
Expanded Base Zone
↓
Vertical Tower Zone
↓
Speaker Support / Hoisting Zone
This is more accurate than describing the entire structure simply as a 12m × something scaffold.
The main tower is approximately 12m high.
That does not mean:
speaker hanging point = exactly 12m.
The actual speaker elevation depends on:
top truss position;
hoist arrangement;
flying frame;
sling arrangement;
speaker-array dimensions;
required ground clearance;
final connection geometry.
Therefore, two dimensions should be treated separately during quotation:
Required Tower Height
and
Required Speaker Hanging Height
They are related, but they are not interchangeable.
The original product uses Delay Towers, which makes sense from an audio-system application perspective.
But “delay tower” primarily describes where the speaker position is used within the audio layout.
It does not tell the DragonStructure reader how the temporary structure itself is configured.
For this page, the more useful structural search intent is:
How is a 12m Ringlock speaker tower built when the main tower uses three additional 2m auxiliary base modules?
That is why:
12m Ringlock Speaker Support Tower with Three 2m Auxiliary Base Modules
is a stronger DragonStructure title.
“Delay tower” can remain in the application text and SEO vocabulary without being the primary structural product name.
At a structural-breakdown level, the system can be understood in the following sequence:
Establish the 10 confirmed ground support positions.
Install the adjustable bases.
Set the first level of 2m vertical standards.
Connect the lower horizontal ledgers.
Build the main tower base and the three auxiliary base modules together.
Install the corresponding diagonal members and supplied brace components.
Complete the approximately 2m-high expanded lower structure.
Stop the three auxiliary modules at this level.
Continue the main Ringlock tower upward using repeated standards, ledgers and diagonal braces.
Reach the approximately 12m main-tower height.
Integrate the 2.5m CS40 aluminum top truss according to the confirmed connection arrangement.
Install the specified hoisting/rigging components for the final equipment configuration.
This explains the modular sequence. It is not a complete engineered erection method.
The confirmed BOQ does not list:
stair modules;
ladder modules;
working platforms;
trapdoor platforms;
guardrails.
Therefore, technician access should not be presented as part of the standard supplied configuration.
If the project requires personnel to reach elevated positions for:
rigging;
inspection;
cable management;
speaker connection;
maintenance,
then the access method should be defined separately.
This follows the DragonStructure Product rule that missing components should not be invented simply because they may appear on other tower systems.

Speaker / Line-Array System
This is the central structural logic of the product.
This structure can be considered for temporary sound-support positions in:
outdoor concerts;
music festivals;
large live events;
PA delay positions;
distributed concert sound systems;
speaker support beside or away from the main stage;
temporary line-array support positions.
The term delay tower is particularly relevant when the tower is used away from the main PA position to support additional speakers for audience coverage.
However, DragonStructure should not imply that every 12m tower automatically functions as an acoustically designed delay position. The acoustic layout belongs to the sound-system design.
A similar structure may change significantly according to the project.
This configuration uses approximately 12m.
This structure uses:
3 × 2m-high auxiliary modules.
That is a defining variable—not merely an accessory count.
The available installation area needs to accommodate the expanded lower structure, not only the main tower.
The confirmed configuration uses:
CS40 389 × 389 × 2500mm aluminum square truss.
A different speaker/rigging arrangement may require a different interface.
Provide:
brand/model;
cabinet dimensions;
number of cabinets;
flying frame details.
Provide the actual equipment information for project-specific verification.
This BOQ includes one manual hoist and one fibre sling. A different system should be confirmed separately.
Define whether personnel need access to elevated work positions.
Outdoor/indoor application, available footprint and relevant ground/site information should be provided before finalizing a project configuration.
For quotation or adaptation, provide:
required main tower height;
required speaker hanging height;
number of towers required;
whether the tower is main PA, side PA or delay position;
speaker brand/model;
cabinets per array;
cabinet dimensions;
total suspended equipment weight;
flying frame information;
hoist requirement;
top-truss requirement;
available ground footprint;
distance/relationship to stage;
access requirement;
existing Ringlock components, if any;
existing aluminum truss, if any;
drawing or site layout;
site photos;
indoor/outdoor application;
project location;
relevant ground/site conditions.
A useful configuration path is:
Sound-System Requirement
→ Speaker Position
→ Required Hanging Height
→ Main Tower Height
→ Ground Footprint
→ Auxiliary Base Arrangement
→ Top Truss
→ Hoisting Interface
→ Access Requirement
→ Final BOQ
The supplied product page, BOQ and current project information confirm:
approximately 12m main tower;
three approximately 2m-high auxiliary base modules;
steel Ringlock structural system;
63 × LR2 2m horizontal pipes;
46 × LR3 2.44m diagonal pipes;
36 × LR1 2m pillars;
10 × LR4 0.25m adjustable bases;
2 × 2m × 0.5m steel braces;
1 × manual hoist T1;
1 × fibre sling T4;
1 × CS40 389 × 389 × 2500mm aluminum square truss;
4 × double clamps;
approximately 1270kg packing weight;
approximately 3CBM packing volume.
Based on the supplied configuration and normal Ringlock system logic:
the three 2m auxiliary modules create an expanded lower support arrangement around the 12m main tower;
the ten adjustable-base positions correspond to this larger ground-level geometry;
the 2m standards, ledgers and diagonal members form repeated modular Ringlock bays;
the aluminum top truss provides the upper interface associated with the sound-support arrangement;
the lower 2m zone and upper 12m tower should be understood as different structural zones.
These are structural interpretations, not verified engineering calculations.
The supplied information does not establish:
maximum speaker weight;
allowable suspended load;
allowable point load;
manual-hoist rated capacity beyond the source designation “T1”;
fibre-sling rated capacity beyond the source designation “T4”;
wind rating;
allowable operating wind speed;
ballast requirement;
anchoring requirement;
foundation requirement;
ground bearing capacity;
overturning resistance;
safety factor;
maximum tower height for other configurations;
certification;
local code compliance;
engineering approval.
DragonStructure's governing rules require these boundaries to remain explicit rather than turning practical configuration experience into unsupported engineering conclusions.

The original page functions as a DragonTruss manufacturer/supply product page and provides the commercial product identity, packing information and component BOQ.
DragonStructure should answer a different question:
What 12m Ringlock delay/speaker tower package can DragonStage manufacture and supply?
How is this 12m sound-support tower configured from a main tower, three 2m auxiliary base modules and an aluminum top-truss/hoisting interface?
This distinction keeps the DragonStructure page centered on STRUCTURE BREAKDOWN, in line with the site's Product rules.
Because the complete lower structure is not just the base of the main tower. It also includes three 2m-high auxiliary base modules, creating an expanded ground-level configuration with ten confirmed adjustable-base positions.
No. The main tower is approximately 12m high, while each of the three auxiliary modules is approximately 2m high.
That is the confirmed configuration of this particular structure. The supplied material does not include engineering calculations proving why three were required, so the page should describe the arrangement rather than invent a load or stability explanation.
No. The 8m configuration discussed previously uses one 2m auxiliary base module, while this 12m structure uses three 2m auxiliary modules. The difference is therefore both tower height and lower structural geometry.
Yes. The confirmed BOQ includes one CS40 389 × 389 × 2500mm aluminum square truss.
Yes. The BOQ lists one Manual Hoist T1 and one Fibre Sling T4. These source designations should not be converted into specific rated capacities without corresponding component documentation.
Not necessarily. Tower height and actual speaker hanging elevation are separate dimensions.
No stair, ladder or working-platform system is identified in the confirmed BOQ. If elevated personnel access is required, it should be defined separately.
The structural configuration can be adapted, but compatibility and suitability should not be assumed. Speaker dimensions, quantity, total suspended equipment weight, flying frame, required hanging elevation and hoisting arrangement should be provided for project-specific review.
