portable/stationary Stereo bluetooth speaker
The Goal of my design was to create a speaker that is portable yet can be docked on a stand when home.
I selected the Tang Band W3-214 for the main forward facing speakers in this design for there full range crisp sound and the look they have against american white oak. i also incorporated 2 Tang Band W2-1625SA to hit the lower end that the full range drivers couldnt quite hit
The design is a simple, modern clean design based mainly on aesthetics. all the drivers are isolated with the recommended capacity as quoted on their parts express info pages. the woofers however have a little less room but when docked on the solid oak functional stand, the lower woofer is free to resonate in the stand giving a much fuller sound
the enclosure is assembled using rabbet joints all round and finished with a roundover on every edge. the internal compartments are made in ply and butt jointed with glue only.
Crossovers used are only on the woofers and are simply a 1mh inductor in series with a 20uf cap in parallel after the inductor but before the woofer. this cuts the highs but still keeps the lows and some mids up to about 500mhz-1khz. the full range drivers need no crossover.
Tips & Tricks:
Work hard and always test on scrap if you are in doubt as to whether or not your cut or drill hole is going to work out.
The over all design and appearance i think is great. the Amp board it perfect for the application. the drivers sound better then expected thanks to the addition of the woofers. a little less portable then i would have liked as is very heavy.
