1TD-X to Veritas One Conversion Kit
Criton 1TD-X to Veritas One Conversion Kit
Reference-level detail, premium components, and a complete DIY build experience built around a true beryllium tweeter.
A compact speaker kit with true high-end intent.
This kit was designed with a simple goal: deliver true high-end loudspeaker performance in a format that is approachable, repeatable, and genuinely rewarding to build.
At the center of the design is a beryllium tweeter, chosen for its exceptional stiffness-to-mass ratio and its ability to deliver extremely low distortion, high resolution, and clean detail without becoming harsh or fatiguing.
The Veritas LD25B-06 is paired with our stellar LDW7 midwoofer and a fully engineered crossover to create a speaker that is balanced, dynamic, and easy to enjoy for long listening sessions.
The Veritas LD25B-06 beryllium tweeter is the heart of the design.
Designed as a complete system, not a box of parts.
Like all of our kits, the Veritas One is fully engineered so every part has a reason to be there. The drivers, cabinet alignment, crossover topology, damping, porting, and assembly approach are all selected to work together.
Matched Drivers
Selected for tonal balance, low distortion, and smooth integration.
Engineered Crossover
Designed for smooth blending, balanced response, and strong real-world performance.
Repeatable Build
SmartNode boards and optional flat packs help remove uncertainty from the process.
Superior crossover components are included with every kit.
Premium Components By Default.
We included the level of components you would expect in only an ultra high priced finished speaker. Nothing critical is left out, and nothing needs to be upgraded after the fact.
- Beryllium Tweeter for clarity, refinement, and low distortion
- Superior Crossover Components with high-quality capacitors, inductors, and resistors
- SmartNode Crossover Boards for clean and repeatable assembly
- Internal wiring, 3D printed jig, 3D printed adapters, and hardware

What you can expect.
Refined detail
A clean, highly detailed top end that avoids the etched or fatiguing sound people often associate with “detail.”
Natural vocals
Strong midrange clarity and tonal balance help vocals and instruments sound believable.
System scaling
Better electronics and better recordings are easy to hear as the rest of your system improves.
Specifications & Measurements
Engineered, measured, and validated as a complete system.
The Veritas One was designed as a complete loudspeaker system, not just a collection of premium parts. The crossover, cabinet tuning, drivers, and acoustic response were developed together to deliver the same balanced, full-range presentation the 1TD-X is known for, with the added refinement and resolution of the Veritas LD25B-06 beryllium tweeter.

Measurement Data
The Veritas One was measured and refined to deliver a smooth response both on-axis and off-axis, helping it maintain natural tonal balance in real rooms instead of sounding good only from one narrow listening position.
Frequency Response
Smooth, extended response with identical bass performance of the Criton 1TD-X while adding the refinement of the beryllium tweeter.

How does this compare to the Criton 1TD-X?
The Criton 1TD-X has been one of our most popular kits for good reason: it offers excellent bass extension, very low distortion, and a big, full-range presentation that surprises a lot of people for a bookshelf-sized speaker.
The Veritas One keeps the same strong bass and midrange character the 1TD-X is known for. Overall, it has an almost identical frequency response both on and off-axis, but it leans further into top-end refinement, resolution, imaging, and detail retrieval.
The proven all-around performer
Choose the 1TD-X if you want our most established compact kit, excellent bass extension, and a speaker that does almost everything well.
The refined reference option
Choose the Veritas One if you want the familiar CSS balance with a more premium, resolved, and detailed top end from the beryllium tweeter.

Who this kit is for.
- Builders looking for a true high-end result without designing from scratch
- Customers who value low distortion, long-term listenability, and fine detail
- Listeners who want the refinement of a premium tweeter in a compact CSS design
- Anyone looking to step into reference-level performance at a fraction of finished-speaker pricing
Ready for a serious compact speaker build?
We build and assemble these kits in batches, and certain components—particularly the beryllium tweeter—can have longer lead times depending on supply.
If this is a project you’re considering, it’s generally best not to wait too long.
