SPEAKER ENCLOSURE DESIGN PRINCIPLES DRIVER
Bass Principle: Ported or Bass Reflex with approximate -3dB of 35Hz. podcasturban-design-londonprinciples-urban-design-31000081303492itemimage.png. 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.When following this build plan, the end result should give you a 2.1 speaker system that will have the following approximate specifications: Finishing is up to you and you can follow my build exactly or opt for an enclosure that can be painted in the colour of your choice. When following this build plan, it can easily be built with everyday woodworking tools, and even by someone with beginner woodworking skills. The output of the specified plate amplifier is 30W+30W stereo, and 60W for the subwoofer channel. Now it is up to the user to adjust the width, height, and depth of the speaker box until the volume is. This provides you with the ability to then use this subwoofer with any system or other amplified speakers or just set it to 2.1 and connect a pair of stereo speakers. To use this calculator, we enter a speaker diameter of 4', the Box Volume (0.77 liters), Driver Displacement Volume (0.24 liters), Wood Thickness (3/4' - same as above), and indicate we will be using 3/4' battens. The subwoofer design includes a plate amplifier that can be set to 2.1 or 0.1 output. The goal was to have a relatively small and elegant looking subwoofer that can fit into most home environments. It is a ported bass reflex enclosure with the port firing forward. I could have simply modified the enclosure for a three-fold line, a very old TL design going back to 1971, but before I. No question about it, they sound very good in the Audio Artistry speakers - with Linkwitz as the designer, they should. A cross-sectional view of such a design is shown in Fig. This subwoofer was designed around a down-firing Tang Band 6.5 inch subwoofer driver. of a 9900 without the shallow horn, thus the 9700. For use at lower frequencies, many manufacturers have evolved variations of the horn principle called the folded horn design. I made this design for my 55inch TV, but if you want to adjust the length, you can just recalculate some of the dimensions to suit your TV.

This sound bar is intended to be used with the 6.5 inch subwoofer build with 2.1 amplifier module. You can also connect this sound bar to an AVR or to a subwoofer with 2.1 amplifier output. The rear of the speaker enclosure is typically designed to prevent radiation of the rear sound pressure wave.
In general, a spacing of 1 to 2 mm will be sufficient for most mini and micro speakers. The left and right enclosures are sealed. The front of the enclosure should be spaced far enough from the speaker, so the moving diaphragm is not able to come in contact with the enclosure.

This sound bar was designed around 2.5 inch full range drivers and 3/4 inch tweeters.
