Boombox, part 6
Final touches, not much to it.. :)
For fastening the speakerbox to the trolley, I decided to test door locking latches. The ones I have turned out not too good a fit (required a bit of bending), so it remains to see how well they last in the long run. They’re fastened both to a metal sheet and the trolley.
When I get to replace the visualizer level adjustment potentiometer, I’ll probably end up rotating the junction box 90 degrees. As it is now, the beer trolley rather effectively blocks the potentiometer from being adjusted. One visualizers seems a bit more sensitive than the other too. If the cause for this turns out to be other than potentiometer-related, I might have to add some “padding” resistor to the more sensitive one.
Figured I’d for once also do a parts expense list, so here you go:
- Lepai LP-168HA amplifier 18€
- Cigarette lighter jack 3€
- Car battery terminals 6€
- Ipod charging cable 2€
- Heart-shaper equalizers 9€
- Can of Hammerite paint (1/4 used) 18€
- Locking latches 7€
- Installation beer 20€
- TOTAL 83€
One additional extra I left out from the list (as well as the pictures) is a +12VDC powered 8-liter cold storage shoulder bag (49€). Not really part of the trolley, but definitely a must for cold beverages. Gotta make use of the car battery ;)
Sound-wise I’m rather happy with what I ended up with. There’s a fair amount of bass though the “deepest end” is non-existent. The enclosure (or the 6″ speakers) does resonate mechanically a bit if bass is cranked all the way up, but this can be in turn masked up by cranking up the treble. All in all, the Lepai amp can drive the speakers to full volume with very little distortion. If standing next to the Boombox, the maximum volume level is bordering around “what did you say?” but definitely not “fuck my ears are bleeding”.. Unless maybe if treble is cranked up.
Reckon that’s all about this project then! :)
