Terms of Sale and Licence

Effective 6 October 2026. These terms apply to every purchase of SpeaD software from Redrock Acoustics LLC.

Part 1 — Terms of sale

Who you are buying from

SpeaD is published by Redrock Acoustics LLC, a New Mexico limited liability company, 5 Sundagger Loop, Placitas, NM 87043, USA (“Redrock”, “we”). Online orders are processed by our reseller and Merchant of Record, Paddle.com, which sells the licence to you, takes payment, issues your invoice and handles sales tax and VAT; Paddle’s buyer terms also apply to those orders. Orders paid by bank transfer are sold and invoiced by Redrock directly.

What you are buying

You buy a licence to use SpeaD, not the software itself. The licence is granted by the end-user licence agreement in Part 2, which you also accept when you install SpeaD. The products, seats, update periods and prices are those shown on our pricing page at the time of your order, or in a written quotation from us.

  • Perpetual licences (SpeaD Single, SpeaD Professional, additional seats, upgrades, Box & Crossover Designer) can be used without time limit. They include updates released during the update period stated at purchase.
  • Annual and monthly licences (SpeaD A, SpeaD FEA, the update subscription) run for the period paid for and renew automatically until cancelled. You can cancel at any time; the licence then ends at the close of the paid period. Ending one never affects a perpetual SpeaD licence you own.
  • Seats. Each seat is one computer at a time. A seat can be moved to another computer by deactivating it first.

Prices, taxes and payment

  • Prices are in US dollars.
  • Online orders are paid at checkout by the methods Paddle offers. Paddle adds any sales tax or VAT that applies in your country.
  • Bank transfer orders are paid 100% in advance against our pro forma invoice. All sending and intermediary bank charges are for the buyer’s account, so that the full invoiced amount is received. Prices on bank transfer orders exclude any taxes, duties or levies payable in the buyer’s country.
  • Quotations are valid for the period stated on them.

Delivery

SpeaD is delivered electronically. Your licence key and download instructions are emailed to you, for online orders shortly after payment and for bank transfer orders within one business day of cleared funds. Nothing is shipped.

Refunds

Perpetual licences can be refunded within 14 days of purchase, and the licence key is deactivated when the refund is made. Annual licences include a 14-day free trial and can be cancelled at any time. The full terms are in our Refund Policy.

Pre-release versions

Before SpeaD 1.0 is released, purchased licence keys are issued for the release version. Beta and pre-release builds offered to testers are free of charge, test software, and governed by Section 5 of the licence agreement.

Privacy

How we handle the information you give us when you buy, register and activate SpeaD is described in our Privacy Policy.

Part 2 — SpeaD End-User Licence Agreement

Agreement version 2026-09-30. SpeaD release builds show this agreement during installation and ask you to accept it.

IMPORTANT - READ CAREFULLY. This End-User Licence Agreement ("Agreement") is a legal agreement between you (either an individual or the organisation you represent) and Redrock Acoustics LLC, a New Mexico limited liability company ("Redrock"). By selecting "I accept", or by installing, activating or using SpeaD, you agree to this Agreement. If you do not agree, do not install or use SpeaD. If you accept on behalf of an organisation, you confirm you have authority to bind it.

SPEAD PRODUCES ENGINEERING ESTIMATES. EVERY RESULT MUST BE VERIFIED BY PROTOTYPE AND MEASUREMENT BEFORE IT IS USED FOR TOOLING, PRODUCTION, PURCHASING OR ANY OTHER COMMITMENT. YOU ACCEPT FULL RESPONSIBILITY FOR HOW YOU USE THE RESULTS (SECTION 6).

1. Definitions

  1. "Software" means SpeaD, its add-on modules (including the Box & Crossover Designer and the SpeaD-A and SpeaD-FEA tiers), Licence Manager, the Data Manager, the bundled material and component data, documentation, and any updates or pre-release builds Redrock provides.
  2. "Licence Key" means the key Redrock issues to you, tied to your registered email address.
  3. "Seat" means one computer on which the Software is activated at a time.
  4. "Licence Term" means perpetual for a purchased perpetual licence, or the period stated when the key is issued for a subscription, trial, beta or educational licence.
  5. "Results" means any value, curve, drawing, specification, file or other output the Software produces.

2. Licence Grant

  1. Subject to this Agreement and payment of any applicable fee, Redrock grants you a non-exclusive, non-transferable licence to install and use the Software, in object-code form only, on the number of Seats your Licence Key allows, for the Licence Term, for your internal business, engineering, research or educational purposes.
  2. The features available to you are those enabled by your Licence Key. Features not enabled are not licensed, even if present in the installed files.
  3. A perpetual licence includes updates released during the update period stated at purchase (for example one year for SpeaD Single, two years for SpeaD Professional). After that period you may keep using the last version released within it.
  4. The Software is licensed, not sold. Redrock and its licensors keep all title, copyright and other intellectual property rights in the Software, including its calculation methods, calibration data and measured data stores. No rights are granted except those stated here.

3. Restrictions

You must not, and must not allow anyone else to:

  1. use the Software on more Seats than your Licence Key allows, or share, publish, sell or transfer your Licence Key;
  2. copy the Software except for one backup copy;
  3. decompile, disassemble, reverse engineer or otherwise attempt to derive the source code, calculation methods or data of the Software, except to the extent applicable law expressly permits despite this restriction;
  4. remove, disable, bypass or tamper with the activation, licence verification or copy-protection features, or modify the Software's files;
  5. extract, copy or redistribute the Software's bundled data (including material data, magnet curves and measured suspension data) other than as Results in the normal course of use;
  6. rent, lease, lend, sublicense or provide the Software as a hosted or bureau service to third parties; or
  7. use the Software to build a competing product.

You may share Results you create with your customers, suppliers and colleagues.

4. Activation and Online Verification

  1. The Software must be activated with your Licence Key and your registered email address. Activation records an identifier derived from the computer's hardware; it does not collect the contents of your files or designs.
  2. The Software checks your licence with Redrock's licence server when it starts and periodically while running. If it cannot reach the server, it continues to run for up to 7 days from the last successful check, after which it will not start until a connection is restored.
  3. You may move a Seat to another computer by deactivating it in Licence Manager, or by asking Redrock to release it.
  4. Redrock may suspend or revoke a Licence Key that has been shared, used beyond its Seats, obtained fraudulently, or not paid for. A revoked key stops working at the next licence check.
  5. When you send a report through Help > Send Feedback, the Software sends the information shown in the report form, which may include the open design file and a technical log. Redrock uses it only to support and improve the Software.

5. Beta and Pre-Release Software

  1. Redrock may offer pre-release builds (marked beta, pre-beta, preview or pre-release) of future versions or modules. They are test software: incomplete, possibly containing serious errors, and their calculations may change between builds without notice.
  2. Results and files from a pre-release build may change before the corresponding final release. You must not rely on them for any design, production, purchasing, publication or commercial decision until that final release is available; re-run and verify them as Section 6 requires.
  3. Feedback you give may be used by Redrock without restriction or payment. You must not publish benchmark or comparison results from a pre-release build without Redrock's written consent.

6. Engineering Results - Your Responsibility

  1. The Software is a design aid. Its Results are estimates produced by numerical models, curve fits, measured-data interpolation and finite- element methods. They depend on your inputs, on material and component data that may be incomplete or inaccurate, and on assumptions that may not hold for your design.
  2. Results may differ materially from the performance of a physical product, including Thiele-Small parameters, force factor (Bl), inductance, excursion limits, stiffness, frequency response, impedance and thermal behaviour.
  3. You are solely responsible for: (a) checking that your inputs and any data you import are correct; (b) verifying every Result by building and measuring prototypes before relying on it; (c) all design, safety, regulatory and commercial decisions you make; and (d) the products you design, make or sell.
  4. You must not use Results as the sole basis for tooling, production, procurement, safety-related or regulatory decisions.
  5. Component and supplier data in, or imported into, the Software is provided for convenience. Redrock does not verify it and it may not match the parts you actually receive.

7. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SOFTWARE AND ALL RESULTS ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. REDROCK DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE AND NON-INFRINGEMENT. REDROCK DOES NOT WARRANT THAT THE SOFTWARE OR ANY RESULT WILL BE ACCURATE, COMPLETE OR ERROR-FREE, THAT IT WILL MEET YOUR REQUIREMENTS, OR THAT IT WILL RUN WITHOUT INTERRUPTION. NO ADVICE OR INFORMATION FROM REDROCK CREATES ANY WARRANTY NOT STATED IN THIS AGREEMENT.

8. Limitation of Liability

  1. TO THE MAXIMUM EXTENT PERMITTED BY LAW, REDROCK, ITS MEMBERS, EMPLOYEES AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, GOODWILL, DATA OR PRODUCTION, OR THE COST OF TOOLING, RECALLS, REWORK OR SUBSTITUTE GOODS, ARISING FROM OR RELATED TO THE SOFTWARE, THE RESULTS OR THIS AGREEMENT, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF REDROCK HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
  2. REDROCK'S TOTAL LIABILITY ARISING FROM OR RELATED TO THE SOFTWARE, THE RESULTS OR THIS AGREEMENT WILL NOT EXCEED THE AMOUNT YOU PAID REDROCK FOR THE LICENCE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR US$100 IF YOU PAID NOTHING (INCLUDING FOR BETA, TRIAL AND EDUCATIONAL LICENCES).
  3. These limits apply even if a remedy fails of its essential purpose. Some jurisdictions do not allow certain exclusions or limits; in those places they apply only to the extent the law allows.
  4. You will indemnify Redrock against third-party claims arising from products you design, make or sell using the Software or its Results.

9. Updates and Support

Redrock may provide updates, fixes and new data at its discretion and may change or remove features. Support is provided by email on a reasonable- efforts basis unless a separate written support agreement says otherwise. Updates are governed by this Agreement unless they come with a new one.

10. Term and Termination

  1. This Agreement lasts for the Licence Term. It ends automatically if you breach Sections 2 or 3, and Redrock may revoke your Licence Key.
  2. On termination you must stop using the Software and delete all copies. Sections 3 and 6 to 13 survive termination.
  3. Fees paid are non-refundable except as stated in the Refund Policy (refund.html), where the law requires otherwise, or where Redrock agrees in writing.

11. Export and Compliance

You will comply with all export control and sanctions laws that apply to your use of the Software, including those of the United States. You must not export or use the Software in or for any embargoed country or restricted person.

12. Governing Law and Disputes

This Agreement is governed by the laws of the State of New Mexico, USA, without regard to its conflict-of-law rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply. The state and federal courts located in New Mexico have exclusive jurisdiction, and each party consents to it.

13. General

  1. This Agreement, together with any quotation or invoice Redrock issues for your licence, is the entire agreement about the Software and replaces any earlier understanding. If they conflict, this Agreement governs, except for price, seat count and update period, where the invoice governs.
  2. If any part is held unenforceable, it will be enforced to the maximum extent allowed and the rest remains in effect.
  3. You may not assign this Agreement without Redrock's written consent. Redrock may assign it in connection with a merger, acquisition or sale of the business.
  4. A failure to enforce any provision is not a waiver.
  5. If this Agreement is translated, the English version governs.
