Boombox no.2! :D

[Saturnus]

First rule of a good boombox build. Don't ever use anything that is meant for car audio. Ever.

Oh, and since you're nearing the Boominator dimensions anyways, why not just build that?

Because i already got 4 6x9 speakers i want to use.
I would rather build the boominator but it'll cost 70€ more.
And i know, it feels silly to choose the amp9 instead of the amp6, but heres why:
I'm mainly planning on using it just some hours at night, not using it as a festival stereo.
Also why i choose to have 2x 12v 18Ah batteries

And saturnus, how does the magnet-magnet construction work?
How did you put together the magnets?
I really dont have a clue how you did that

Please someone reply how the magnet-magnet construction works, need an awnser within 2 days.
Im going to start building the box on wednesday.


And i was thinking of a tone control :P
I can buy this for 10€, what du u guys think?

Btw, i plug it in between the amp and my smartphone and not between the amp and the speakers right?

there are many magnet-magnet configurations , in which speakers can be wired in phase or out of phase . I prefer the push-pull configuration ,because
the size of the box remains the same as a single woofer . They can be mounted nose to nail , or back to back . Since yours is a very large box , I suggest to try the design I posted : the back of the woofers share the same chamber ,they are wired out of phase , and the other chamber is vented (hole
or duct ) .

Oh, that changes everything :S
Right now i have made everything so the magnets meet each other inside the box (like the boominator),
if i will do this type i will have to make the boombox thinner but longer, about 1m long.
And if its thinner, the batteries wont fit as planned.
Is it possible to do it like the boominator thingy?

And it's not really a woofer, it's a coaxial speaker, so wouldn't the tweeter and the mid sound get reduced when using the vent idea? or am i wrong?

Wiring the speakers out of phase will also mean that there would be next to no bass at all. Probably not a good thing.

You also get none of the benefits of mount the magnets against eachother.

No ,you 're right , as I didn't mention that you should extirpate those protruding things out of the cone .

Waaaaiiiitttt, so you mean i can just pull out the mid and the tweeter from the coaxial? XD

So the magnet-magnet thing is just a waste of time, you just meant i should have the same woofer in the same room to get extra dB?


Now i am reaaaalllly confused >.<
