This group is intended for the discussion of loudspeaker design simulations done with the MathCad worksheets found on the Quarter Wavelength Loudspeaker Design web site. Topics can include questions or discussions concerning the use of the worksheets, the articles on the site, or general speaker design theory. While the original intent of the web site was for presenting the study and computer modeling of transmission line loudspeakers, the content has expanded to include back loaded horns and dipole speaker systems. All future announcements about new site content and new MathCad worksheets can be found in this Group.

Due to a spammer recently joining the group, I have been forced to change the membership options to approve all new members. No big deal, I am not trying to restrict membership, joining is a simple formality ...... unless you are the spammer.

The group is really intended for home audio (two channel music or home theater although I know next to nothing about the later) applications. Please no car audio or dB competition discussions.



---> ATTENTION NEW USERS <---

Recently I have had a couple of problems sending User IDs to new subscribers. This has happened in particular with gmail and hotmail addresses. I send the information and then a few days later I get a request for a User ID. As far as I know the initial e-mail has been received when obviously it has not for some unknown reason.

So if you have subscribed, or are planning on subscribing, and don't hear from me within 24 hours please let me know and I will re send the access information. I try and respond to all new users within 24 hours, it is rare that a response is not within this time window.

Thanks in advance for your patience if things get screwed up by the e-mail Gods.
