The Audio Mecca is Dick Olsher's corner in cyberspace, complete with audio reviews and DIY projects. My main objective is to share new speaker design ideas with the global DIY community. Your feedback and suggestions are always welcome at blackd@blackdahlia.com. Thank you for visiting.

Note: these projects are presented to give an historical perspective of my published designs over the past 35 years. In almost all cases, the specified drivers have sadly been discontinued and are no longer available. There are currently no plans to update these projects and no technical support is being offered. For the past several years my design energy has been focused on the BassZilla loudspeaker family as well as other open baffle designs. You can find information about the OB2 loudspeaker in Tip of the Month #59.
