its a very much flawed design to be honest :P

drivers are 2 beyma 8BR40, 2 fane sovereign 6", 2 APT80

tri-amped off sure 2*100 boards, with a 12V car crossover. power is 3 7Ah lead acids

weight 25kg, battery life 6-7 hours, -3s are ~70hz, ~18khz

but its fun and loud

Hey guys

I've been browsing this and other forums for a while and little more than a month ago i decided to build my own boombox.. The boominator was an excellent inspiration and i've built something quite similar..

I shot some pictures while making it.. Enjoy


Cutting the wood.. I used 12mm birch plywood, as in the Boominator.

The weather was really nice, so i made myself an ad-hoc workstation outside :-)

Its pretty big.. I made it 20cm longer than the boominator as i wanted more space in the center compartment for future addons :-)

Nearly finished with added speaker grills:

It sounds AWESOME.. I've already used it for several outdoor events and people are astounded by the looks and sound of it.. People come up to me asking where they can buy something like that - I love the look on their faces when i tell them i built it myself :-)

I still have several additions planned but due to lack of funds atm im waiting until spring to add more stuff too it..

I'm very happy with my results and even though the weather is getting colder i've used it a lot!

Thanks a lot for all the great info on this thread, its been amazing :-)

Thanks, im pretty happy about it

I used 4 Piezo tweeters
And 4 x p.audio HP-10w as used in the Boominator..

I think i spent about 40 hours on research reading here, and other forums.. And I spent about a week making it with 2-7 hours work each day.. So in total it was around 70-80 hours

Love it Phaedras, it looks great! What do you think about the tweeters, can they match the hp10w's output ok?

I've been thinking about building a mono boominator, with 2 drivers, mounted magnet to magnet, which should be around half the size.

Would this work ok? I guess it wouldn't put out as much volume but it would be a lot smaller. I could easily build a 2nd one and bolt them together making it (sort of) modular.

Also, I noticed some people in this thread have used driver with a neo magnet, would these also gain efficiency by mounting them magnet to magnet in the same way that the hp-10w's gain efficiency?

Thanks man.. Im really happy with it..

I started out with 150ohm series resistors on the tweeters and then tried out 120 and 100 aswell and the sound wasnt that great.. The tweeters couldnt really match the hp-10w's and it sounded a bit hollow..

But when i removed the resistors and just hooked up the tweeters with full signal it sounded great, so thats the config im sticking with now.. It might be because the spl of the tweeters is 95 and the woofers is 96.. I dont know - someone more knowledgeable might be able to clarify this :-)

Hello everyone, and thanks for a very interesting thread!

I began reading it pre-Roskilde '10, after I finished my Partybox. But after watching and listening to some Boominators and some Boominator-inspired boomboxes at Roskilde festival I knew that my boombox, allthough great looking, wasn't loud enough.

I've just started manufacturing a Boominator myself, and i promise you, pictures will follow.

The design is almost entirely based on Saturnus original, but i decided to go bigger, and tuned it a little different. I bought 4 x P.audio HP-12W. The tweeter is the same as Phaedras.

Me and my brother started manufacturing it on sunday.

Here are some pictures of the old one, and what-soon-is-to-be-the-new-one.

Picking up the AMP6-BASIC from 41hz Audio today!

I bought the assembled version due to the lack of my soldering skills. Previously, I've only managed to solder speaker terminals, and larger stuff.

But curios as I am, I also ordered a practice solder kit... It feels a little better to have messed up something för 2 € , than something for 50 €

Pictures soon to come!

I've seen that some of you people installed the amplifier in an small aluminium box. I've been searching for this type of box, but so far I have not find any close to Sweden... Anyone who can offer a link?

Hey Closure

Thats gonna be one big boombox with the 12" drivers :-)

I bought my aluminum enclosure here, but im not sure they ship out of the country.. But there are LOTS of distributors around.. Im pretty sure you can go to any electronics shop/website and buy it.. Its very comon :-)

Hope you find what you need and the build is coming along!
