REFLECTOR: speaker in the cabin

[Andrew Ellzey]

Doug,
 
The only issue that I see with your installation is that it could be too close to your whiskey compass. I believe you might have trouble adjusting it when you do your compass swing adjustments. I owned a Cessna 150 in 1986 when I got my license. Just before I flew my solo long cross country, the radio speaker located above the pilot left door quit working. Not having time to order a new speaker before my scheduled flight, I installed a same size 6X9 car radio speaker at the same location and made my flight. What I found was that on the third leg flying due east, my compass was off 15 degrees. Until I figured out what was going on, I thought I had a strong cross wind. I did a compass swing and adjusted the compass a few days latter but never could get it as close as the original adjustment. The only difference between the speakers was the strength and size of the magnets. Your results may vary.

You guys convinced me that a radio speaker in the cabin was a nice convenience, so I ordered a 3 W, 4 ohm speaker from Mouser.  I didn't realize that it was only about 1 inch in diameter. I was going to return it, but then on Valentine's Day I got one of those musical cards for my wife.  It was playing "Don't Worry, Be Happy", and I was amazed at how good it sounded with that little speaker. So I installed the 3 W speaker today in the glare shield in front of the pilot near where the windshield hits the glare shield. The intersection of the windshield and the glare shield forms a natural megaphone, and I think the glare shield is also acting like a sounding board. The sound is clear and plenty loud. FYI.
