2.1 Bluetooth Speaker – Cantilever Style MK2

After designing and building MK1 of this bluetooth speaker with parts that I mostly salvaged from an old sound system, I decided re-design and rebuild this speaker using parts that can be bought of the shelf.

Build plans are available from the shop here.

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

  • Frequency Response: 44 Hz – 20000 Hz (-3dB)
  • Sensitivity: (2.83V/1 m) 83 dB
  • Power Output: (Left/Right Channels) 30 Watts each (4 Ohms), (Subwoofer Channel) 60 watts (4 Ohms)
  • Bass Principle: (3 inch Full Range Drivers) Sealed, (5.25 inch Subwoofer) Bass Reflex
  • Crossover Point: 180 Hz – 250 Hz User selectable (250 Hz recommended)
  • Size (W x H x D): 560 mm x 215 mm x 228 mm

This clip below is a very basic sound test to give you some idea of what this speaker sounds like. It is of course best listened to through headphones at a moderate volume level. It was recorded via a Zoom H1 microphone (http://amzn.to/2gcpLwE) at a listening distance of roughly 2 meters.
