Redrock Acoustics Software
SpeaD 1.0
The Complete Loudspeaker Design Platform
Redrock Acoustics has launched a completely revamped version of SpeaD — a comprehensive loudspeaker design platform that consolidates every subsystem of a driver (motor, voice coil, spider, cone assembly, and system response prediction) into a single unified application. Built on .NET 8 with a modern WPF interface, SpeaD is the successor to the legacy SpeaD that has been a tool of choice for professional loudspeaker engineers for decades.

SpeaD 1.0 is scheduled for release on 1 November 2026. Buy SpeaD outright as a perpetual licence (Single or Professional), add the Box & Crossover Designer module, or license the advanced SpeaD A and SpeaD FEA modules annually or month to month. All prices are in US dollars.

Become a SpeaD beta tester
SpeaD 1.0 is in closed beta with engineers at driver and system manufacturers around the world. If you design transducers professionally, I would like your eyes on it — particularly the motor, spider and cone assembly modules, where SpeaD does the most that other tools do not. Beta testers receive a licence at no cost, direct access to me, and their reports shape what gets built next.
If you are interested in becoming a SpeaD beta tester, please fill in the short form. I read every application personally and will be in touch.
