This is the first project that I am sharing, so go easy. It's another boom box. Maybe we need a boom box forum here? Anyway, the drivers are 5 1/4'' Tannoy full rangers, actually I think they're more like a coaxial without a crossover. They were originally a pair of self powered indoor/outdoor speakers. The enclosures were small plastic jobs that were not doing any justice to these drivers. When I was messing around with them in the original enclosures, they sounded pretty lifeless and had very little bass. During that listening, and after pulling the drivers and hooking them up to a Lepai 2020, I started to realize they were pretty tough drivers. Not a lot of travel, but what seemed to be a fairly large magnet, and pretty high sensitivity. This is all speculation on my part as I don't have a lot of experience with different drivers, and don't have any measuring equipment. I do know that the little Lepai made these things sing……sing loud.
I had no idea what to expect when I put these in a decent enclosure. I originally went pretty big, planning to run the Tannoys sealed in little tupperware bowls, and down fire a Dayton DC-160 to gain some bass. This would have required buying some little plate amp to power the Dayton, and complicated the build a little. So for shts and giggles I gave the Tannoys the whole box, tuned somewhere in the 40's with two 1 3/8 ports. Low and behold, these drivers did more than I would have asked for. They get loud, they get pretty low, they have an upper midrange attack that reminds me of a PA speaker.
The enclosure is made from panels, made from strips I cut, from some 1 5/8" thick MDO plywood. Yes I said 1 5/8". I cut 1/2" strips from a 2' x 4' panel. I wasn't real happy with the look until after finishing. What made it look much better than bare, was filling the grain, I sanded a wet coat of Arm-R-Seal, allowing the gooey slurry to fill all the little nooks and crannies. It helped even out the contrasting color and didn't looks as busy as the raw panels did.
Anyways, here's a few pictures.
A 20 oz. of Vernors for size.
This is actually my fourth boom box, I made two Sprites that turned out really cool, and a kick around Sprite for the garage. I'll have to share pictures of these too.
Thanks for looking.
