Default Big Boombox

Now this is more like it. 12" woofer is better than a 6.5"
125 watts is better than 10.
Ribbons are better than plastic domes.

Now...I guess I better design a box and find an amp for the mid basses and tweeters.

Here's one I just made for my wife, now it's my turn.

Coming soon to a thread near you...

Cal,

Love your designs and taste in speakers but it gets me in trouble. Had the picture of all those horns etc in your driveway on my monitor, my wife spotted it and started cursing.

I'm not making a suggestion or anything but--those A123 Systems 3.2V 20 amp hour Lithium-Iron-Phosphate cells only weigh about 17 ounces each, can output up to 600 amps and are very small. Four of them with correct battery management system board can be charged with an automotive charger very quickly. They won't explode, have 2,000 cycles to 5,000 cycles and should last about 10 years or so.

Nice battery system for a really big boom box--I'm jus' sayin'... Maybe a nice 4 channel bridgeable car amp with crossover... 6.5" horn sub running ??? mains...

Cheers my friend. I do seem do be a little audio 'horny' these days. That's funny 'cause the wife and I are getting along just fine.

Mine just shakes her head. They can buy 25 pairs of shoes without batting an eyelash but speakers? Non comprende. Thankfully, the storage area is not where I live. It's a house I have with my brother, so anytime I need a fix I just go there.

I seem to be there often these days.

Thank you for the battery advice 18 but if I find a place that I can't plug into then I think I will absorb the the environment and not worry about sounds other than what nature and the others around are providing.

Cheers.

I have to stop this. A bi-amped 4 way might be on the horizon.

If I get a decent amp for the mid/highs, I might want to use the Adire Extremis 6.8 for the mid bass, the Aurum Cantus ribbons and little gem of a mid from LG. (pic)

I hate you guys. Stop encouraging me.

That lousy pic might have to do with my unsteady hands as I formulate new ideas, not sure.

If I keep looking at your giant horns, I'll have my own house to escape to...when my wife dumps my butt and takes this one.

My surround sound system is done with my wife's official declaration of "Congrats, it makes noise". Any future attempts at audio devices shall be stored in the garage--the surround sound stays though.

At least I can go "full Cal" for the man cave system, big, heavy and ugly is a good thing for the garage--don't want it to get stolen. Looking at your horns for the big & heavy part, ugly I've already figured out. Have some really nice automotive amps (Phoenix Gold when they were made in Arizona) Then you start rolling out your really nice designs for "boom boxes"... still have that 10" sub laying around.

Reading Cal's posts are going to cost me money--but less than women's shoes.

My wife no longer referes to it as an addiction. She now feels that I should be committed. To which I respond: Honey I am committed. Committed to having the biggest collection of speakers on my block.

Yes, cheaper and holds it's value better than women's shoes.
