Project Category:
Bookshelf Speakers

Project Level:

Project Time:
8-20 Hours

Project Cost:
$100 – $500

Project Description:
Amazing sounding speakers from Parts Express

Design Goals:
Modify an already awesome existing bookshelf design for my living room theater. They needed to be changed into a front ported speaker as they live on an entertainment center shelf. The baffle was not large enough for a round port so I created a font slot-port design.

Driver Selection:


Enclosure Design:
Bass reflex

Enclosure Assembly:
Parts Express design but I raised the height of the enclosure 1 in because I used 3/4 MDF for the top, sides and front baffle, for a more solid enclosure that didn’t require any bracing.

Crossover Design:
Parts Express with additional .22uf cap

Tips & Tricks:
I calculated the Front slot port area using a few online tools, I added the .22uf Cap per the PE Tech Talk forum.

This speaker sounds amazing for $100. The kit is simple and you don’t need to be a mast craftsman to put it together.

About the Designer:
I work on cars, motorcycles and furniture (now speakers) for fun.
