Default Cal's little boombox

(first 4 posts transferred from another thread)

The first pic is the box all taped to protect from the saw. The little amp will be running four Jordan 6T's, two on the front and two on the sides.

Second pic is from the back where the port and now unused speaker connectors along with the place on top where the small Dayton 25W plate amp will go. (on order)

Third is the bottom mount for the woofer along with the drivers. I will be adding feet to the bottom to raise it an inch or so.

I know I'm not known for little stuff but this should be fun and unlike most of my stuff, portable

Colin's suggestion seems like a good one. Keep it nice and simple.

Series it is.

Roger Wilco on that. I'd hate to spend any real time on something so small.

Default Cal's little boombox

I learned a lot here and it was fun. Went from a DVD player to an iPod for source. It just seemed to make sense from the "spirit of the project" point of view.

And in usual Cal style, the little thing cranks. I used the high level inputs on the plate amp as there are no line level on the little Kama Bay amp. The plate amp does not have a high pass so I tapped into the back of it and added 100ufd caps on the Jordan's. Although the Jordan's are not very sensitive, they still are loud enough to pi$$ off the neighbours. The 25 watt plate amp is more than enough. It goes boom boom real nice.

Still some clean-up to do but I've spent a couple days on this and I wanted to post as once again I'm a happy pappy.

Cheers.

Wow, what a change of heart. If I had seen little drivers like that lying around your house, I would have assumed you were planning to feed them to your "normal" drivers.

Nice job Cal! Looks real good and I've wanting to do a similar project for some time now. Were there any cheaper drivers you considered?

Thanks. The drivers were a product of using up some stuff. In fact, if I do it again, I will up the size a bit (I know, big surprise)

Perhaps some 4.5" drivers and a 6.5" woofer. Still small I know but something with a little more gusto. This set up can only annoy the neighbours one down and one over. Next, something than can reach two doors and two floors

This whole thing started because I was building the latest monsters Cal's next venture and a sweet old lady walked by the workshop, took a liking to what I was doing and disappeared for a couple of minutes. When she reappeared she had this little Samsung woofer box from a "home theatre in the box" under her arm and asked if I might have a use for it. Well didn't that set the wheels in motion and as soon as I got the big boys finished, this started.

It's an addiction. Better than some of the others in my life but still an addiction. Wait till you guys see what's coming down the pipe next. Oh man my wife is gonna be mad.

Cheers.

I gotta say I have really enjoyed this thing in the bedroom. Nodding off to the tunes is something I'd forgotten about. The big system in the bedroom loses something when you turn it down enough to fall asleep and that's where this one seems to shine.

Cheers
