Speaker cabinet design and construction pdf
Loudspeaker enclosure - WikipediaPlease use proper safety equipment and procedures when using power equipment. The following information is available for you to use at your leisure. When it comes to selecting an enclosure type to get the best sound from your woofer and matching it to your taste in music, it can be a little confusing. The purpose of an enclosure is to improve bass response and prevent woofer damage from over-excursion. There are a few things you will need to consider before making your final selection that will ultimately affect your choice in subwoofer enclosure style. Here are some of the key points you will need to consider:. Once you have determined the above conditions, you will then be able to make a choice that will get the best bass response.
It was back in that a couple of researchers from General Electric, Chester Rice and Edward Kellogg, patented what remains the basic design for virtually all the world's loudspeakers. In the 84 years since, engineers and enthusiasts have invested a lot of thought and energy in the refinement of Rice and Kellogg's concept, creating a valuable knowledge base for the do-it-yourself crowd. I should know--I recently built the speakers pictured here, and in the process I learned quite a bit about the art and science of a good speaker. At its core a loudspeaker is a surprisingly simple device. The key elements are the drivers, crossovers and the cabinet.
A loudspeaker enclosure or loudspeaker cabinet is an enclosure often box-shaped in which speaker drivers e. Enclosures may range in design from simple, homemade DIY rectangular particleboard boxes to very complex, expensive computer-designed hi-fi cabinets that incorporate composite materials, internal baffles, horns, bass reflex ports and acoustic insulation. Loudspeaker enclosures range in size from small "bookshelf" speaker cabinets with 4" woofers and small tweeters designed for listening to music with a hi-fi system in a private home to huge, heavy subwoofer enclosures with multiple 18" or even 21" speakers in huge enclosures which are designed for use in stadium concert sound reinforcement systems for rock music concerts. The primary role of the enclosure is to prevent sound waves generated by the rearward-facing surface of the diaphragm of an open speaker driver interacting with sound waves generated at the front of the speaker driver. Because the forward- and rearward-generated sounds are out of phase with each other, any interaction between the two in the listening space creates a distortion of the original signal as it was intended to be reproduced. As such, a loudspeaker cannot be used without installing it in a cabinet of some type, or mounting it into a wall or ceiling. Additionally, because the sound waves would travel different paths through the listening space, the sound waves in an unmounted speaker would arrive at the listener's position at slightly different times, introducing echo and reverberation effects not part of the original sound.
A loudspeaker or loud-speaker or speaker is an electroacoustic transducer ;  a device which converts an electrical audio signal into a corresponding sound. Kellogg and Chester W.

I haven't decided yet whether to use drivers from existing speakers I have, all go all new. Alternately is there a design site with plans I can follow to build something that would sound better than the speakers listed above. I wouldn't break those up.
