Sandy listens to Ray Comfort and Kirk Cameron (www.livingwaters.com) sharing the Gospel every Saturday morning on YouTube while she makes our salads for the week so I made a passive speaker for her iPhone (and for her birthday). Curly Maple, Gaboon Ebony, and Curly Redwood, French polish finish. The difference in sound is very obvious - it’s richer, more balanced, and a little louder.

Cold bending the Curly Redwood; I resawed to the point I needed and then soaked it in hot water. After three times and bending successfully more each time I cut the pieces I needed and then glued them together.

Fitting the curved deflector; the square is just a prop to hold the deflector in place for the photo.

Great idea, David...so, did the design pop into your head while sleeping...? Or was it one of your ingenious thoughts...? Very nice...!

Yes! LOL!

I've been thinking about it for weeks and ran through a dozen different ideas while I should have been sleeping. I tried to make a Fibonacci sequence pattern work but just couldn't do it justice with the piece of Curly Maple I had. Plus, if I made it much larger then she would use it and never say a word but I would know that it was taking up too much room on the bar. The deflector idea came to me as I thought about air ports in speakers to allow some air in from the rear but deflect the sound toward the front. I doubt it makes much difference but I like the idea so we'll go with 'it helps'. :grin:

In my effort to make a handful of videos using my new favorite video editing software, DaVinci Resolve, I thought one on building this passive speaker would be appropriate. So even though this thread is close to three years old it's probably better to have the video here than create a new thread (even though with a new thread it will likely be seen more - oh, well...).

This is a short video, a little over 7 minutes long -

Not a bad idea. Although I can still put the phone in a transparent jar to make the sound louder.
Thanks! I didn't have any Curly Maple, Curly Redwood, and Gaboon Ebony jars... ;)
