Announcement

This site in need of an update

  • This site is (not) maintained by 41Hz Audio
  • The site has hundreds of visitors daily.
  • The site has a lot of valuable content but needs an update.
  • 41Hz Audio is a small 1-man business that does not have the resources (time) to maintain the site on a regular basis.
  • The current plan is to convert this into a community driven site and let its users add and update content.


One possibility is to move the site into our main site www.41hz.com or a sub-domain, and set it up so that members of our forum can maintain and update the content.

Another, less likely possibility, is to set up a new site here with its own community.

If you have any input on this or would like to be part of the team, please go to the 41hz site, join the forum and post your feedback there.

Loudspeaker manufacturers

Donate some hardware or buy announcement space here on the site and we will pass this on as an incentive to anyone interested in maintaining the loudspeaker database. The site has visits from hundreds of loudspeaker builders from all over the world every day.

Again, please contact us via the 41Hz Audio site

The site is named after two Australian pioneers, A.N. Thiele and R.H. Small, who defined the Thiele-Small parameters, also known as TS parameters, around 1960-70. However, the site is by no means limited to Thiele-Small parameters; it also contains a lot of other information.
