The rules

diyAudio is a place for all members of the DIY audio community to learn, share knowledge, and enjoy interacting with others interested in the design and construction of audio components. This privately owned forum reserves the right to limit the behavior of its members. The rules will be enforced in good faith to maintain discussion quality and peer respect.



  1. Insulting, intimidating, bullying, harassing or other disrespectful or antisocial behavior
  2. Disruptive behavior of any sort, including Trolling and Threadjacking (Note 1)
  3. Intentionally posting incorrect or flagrantly dangerous information (Note 2) or misquoting other's posts.
  4. Offensive language. (Note 3)
  5. Posting or linking to pornography, illegal download sites, or illegal software
  6. Posting private correspondence on the forums without express permission of the author
  7. More than one account or multiple registrations without moderator approval

You may be given an infraction notice consisting of a number of infraction points and how long they will stick. These are like penalties in sports. If you get 100 points or more you will automatically be placed in the "sin bin" (meaning you can't post) and you will be freed when your points expire. Flagrant or ongoing violations may result in immediate sin binning or permanent banning from posting on this site.


The moderation team has final authority regarding enforcement and interpretation of forum rules and conduct. diyAudio reserves the right to terminate accounts that over time have demonstrated a negative effect on the community.

  • Some members are also forum moderators. You will always see policeman, captain or trooper smiley face icons when moderators are officially posting warnings or directions which will have consequences if not followed.
    Moderators work as a team to enforce the forum rules. Most moderation actions are reviewed by the team.

  • Moderators are not allowed to edit offending posts; they must delete an entire post if part of it violates the rules.

  • Some threads become repetitive or conflict prone. The moderation team will, at its discretion, close these threads. Starting a new thread to discuss the same topic is prohibited.

  • If you see a post that needs moderator attention or if you just need help, please use the "Report Post" button. This is the quickest way to get the attention of the moderation team.

  • Different levels of membership are not a consideration when moderating actions are taken.

  • Insulting or harassing a moderator for official decisions online or through private message or e-mail is a very serious offense and will usually result in banning.

  • Threads or posts about site moderation are not allowed and will be closed and/or deleted. Please handle questions and comments about how to improve the site or moderation via the "Report Post" button, PM, or the contact form.


Note 1: Trolling is posting inflammatory, extraneous, or off-topic messages in an online community with the intent of provoking other users into an emotional response or of otherwise disrupting normal on-topic discussion. Threadjacking is the practice of taking over a thread by posting off-topic replies such that the original topic becomes diluted or lost. Off-topic posts, and replies to off-topic posts, can be a positive outcome of discussion, but must either be brief or be moved to another thread. If something interesting does arise that warrants extensive discussion -- then start a new thread and link to it.

Note 2: While most projects on this site deal with electricity and construction which inherently involve some risk, particularly dangerous topics and procedures should include a warning in the thread that adequately explains these risks. Certain inherently dangerous topics are not allowed. At this time they include but are not limited to: discussing power supplies directly fed by mains current without a transformer, and mucking about in CRT video monitors. Posts and projects are those of individual members of diyAudio. The forum itself is not in the business of vetting projects or posts for safety, accuracy, performance, reliability, function, or fitness for use. If you attempt to make something and it blows up, or turns expensive parts into charcoal, or just doesn't work the way you were hoping, that's between you and the person posting the project or idea. The forum is merely a bulletin board which allows anyone to post ideas, criticisms, or discussions. It is up to the individual to make the final determination of how appropriate a project is for them to attempt, based on their own experience"

Note 3: Sure, most of us use four letter words in normal conversation without too much thinking, but this forum is about thinking. Over the years this forum has had a strict language code and it seems to have worked well to create a positive atmosphere, where people from different places and cultures feel comfortable. Attempting to circumvent the auto-censor is not allowed.

Note 4: The regular forums are non-commercial and should have no advertisements or overtly commercial threads or posts. These belong in the appropriate Commercial Sector forums. Commercial entities may have threads and post in the regular forums discussing theory and initial product design. If a project gets close to commercial availability, the topic must be continued in a Commercial Sector thread.

Discussion of product design considerations may also be discussed by commercial entities in the regular forums, but promotion of specific products is not allowed. Members who want to start commercial threads may do so at no cost in the Vendor's Bazaar. Those who want more commercial exposure are encouraged to contact the management to discuss terms for obtaining a Manufacturers Forum or Vendor's Forum in the Commercial Sector. Banners and display advertisements are also available.

The commercial threads are for private transactions between members and other members or companies. provides these forums as bulletin boards for the convenience of our members, but makes no warranty nor assumes any responsibility regarding unsatisfactory transactions. Customers can post any issue in the relevant thread to be answered by the vending party, as long as it is done in a civil manner. Normal diyAudio rules about member conduct apply and will be enforced. Please use the commercial sector bulletin boards at your own risk and using your own judgment.
