Awesome project and great images. Very professional, well done!

Awesome looking speaker! Well done! Given the amp is stereo, I assume you use a channel of the amp per woofer, so how is the single tweeter wired in? Is it just wired to one channel?

Thanks!

Thanks manuelmasc!

Thanks JustBoomAudio! If you guys ever do either a mono bluetooth amp or even better, a two channel one with DSP, let me know! I'd love to a 3D printed, battery powered bluetooth speaker, in mono with a woofer and tweeter. Decent amps that are suitable for this application are hard to find...

Awesome Instructable and great project to make!I decided to use a 30 cal box to make it a bit more portable, recess the speakers so there was less chance of damage and use some different parts that I had lying around. Other parts were:Sure Electronics JAB2 2x30W amp sourced directly from Sure (with cable package)Dayton Audio DS135-8 wooferDayton Audio ND20FB-4 tweeterRoadkill brand sound deadener to line the box12mm MDF panel for mounting speakersUrethane adhesive for attaching the MDF pannel and sealing around it20mm dia PVC pipe and elbow for port3.5kHz 2nd order crossover. I had to custom build this to accomodate the impedance mismatch of the speakers - off the shelf ebay ones don't specify what impedance values they are for, so won't work correctly with drivers of the opposite imped...
