[Paul Spencer] All links are to actual horn projects you can build, although some plans you will have to pay for. Suggestion: Right click on links and select "open link in new window." Then you can jump back to this page quickly. Please note: This is an interactive list - if you find other bass horn plans, please add them to the list. If some of the links are dead links, please add a note but don't delete the link as the site may have moved, and this can be fixed. = Lab subwoofer = [Lab sub plans and information] Designed by Tom Danley and using the Eminence Lab12 driver, which was specifically designed for use with this sub. Two of this driver is required. It measures approx 1.1 x 1.1 x 0.55m and is a 27 Hz subwoofer, designed primarily for pro sound use in stacks of 4 or more. The only factor which may prevent use in the home is its size. DIY enthusiasts are lucky to have free plans for a bass horn designed by a horn expert with Tom's credentials. = Pi Speakers bass horn = [The Most Powerful Subwoofer in the World?] Wayne Parham of Pi Speakers has designed a bass horn, the 12Pi basshorn subwoofer, which is similar to the Lab horn but with some improvements in performance: - heat exchanger to increase thermally limited power handling - larger so that stacks aren't required: 1.2 x 1.2 x 0.75m - push pull driver mounting results in more linear performance and lower even order harmonic distortion (similar to the role of a shorting ring, but more effective and with no added cost) Even with 1600w input into a single horn, distortion products at 50 Hz are 35db below the fundamental! At 30 Hz, however, distortion products are only 7db down. [simulated performance charts] [development history] [12Pi vs Lab sub] The driver used is the same as the Lab12. = Bill Fitzmaurice plans = [www.billfitzmaurice.com] Small bass horns of interest for home use: * Tuba 18 - 18" cube - tiny for a bass horn * Autotuba - approx 14" x 15" x 32" * Table Tuba - approx 30" x 30" x 18" It appears that Bill has plans for some of the smallest horn subs on the net, using an MCM 8" subwoofer driver. Some of his PA designs use much larger cabs. = speakerplans.com = [www.speakerplans.com] These are very large horns designed for prosound use, hence they are very large, use pro drivers and have extension typically to 50 or 60 Hz only. Probably not a good choice for home use. The FAQ section of the site is very informative. = Bruce Edgar Horns = [www.volvotreter.de] Contains some Edgar horns with plans = Decware = [Jensen Imperial] = DIY bass horn projecs - miscellaneous = [Mattias Andersson: 50 Hz exponential bass horn for JBL 2220A 15"] [Jeff Robinson] [A HUGE horn system for some inspiration] [Click on the link: "Kolbrek sub horn"] [Adrian Mack] [Architectural horns] [Vincent Brient 30 Hz Horn] [Mike.e 40 Hz horn] [JBL 40 Hz horn] [William Cowan 25Hz horn, Compact 40Hz horn, ] [ John Sheerin 27Hz horn] = next [Bass horn miscellaneous info] = |
