Small 2-Way Stereo Speakers – Build Plan


Build this Small 2-Way Stereo Speaker Set by downloading this detailed 21 page plan that will show you how to go about it. The plans provide you with detailed step-by-step instructions and a list and links to tools, parts and materials that you will need. This plan is great for the intermediate builder and can also easily be built by an advanced builder.

*Build plan dimensions are given in millimetres.



When following this build plan, the end result should give you speakers that will have the following approximate specifications:

Drive Units:

  • Woofer: 3-1/2 inch Aluminum Cone driver from Dayton Audio
  • Tweeter: 3/4 inch Soft Dome tweeter from Dayton Audio

Enclosure Description:

  • 2-Way vented-box system

Frequency Response:

  • -3dB at 68Hz and ±3dB from 800 to 20000Hz on reference axis


  • Approximately 83dB

Nominal Impedance:

  • 4 Ohm

Crossover Frequency:

  • 4200Hz

Recommended Amplifier Power:

  • 15 – 30W into 4 Ohms


  • (W x H x D): 135 mm x 210 mm x 193 mm

A speaker this size will not be able to produce room shaking bass, but these Dayton Audio woofers will surprise you. It sounds like you are listening to a much bigger speaker. It was designed to be small and provide very good midrange quality, but still to produce a relatively powerful sound output. These speakers are best positioned at least 2 feet away from the rear and side walls.
