The Boominator - another stab at the ultimate party machine

I finally read the entire post. Took me a couple of months. I had lots of questions but felt I needed to read all before I posted a question. I either forgot or questions were answered.

This thread rocks. Saturnus you created an amazing boombox. My first response was that I wouldn't have done it that way, but after reading through the thread I realized how much thought went into design and how little I understand festival speakers.
Good job

Thank you very much rubennn! This was exactly what I was looking for 🙂
Will begin building my Qubinator soon, very usefull pictures that I'll have a lot of use for. What is the black paste you are using as glue and more? Is it chemical metal?
And the most important, are you happy with the sound of the Qubinator? 🙂

You can try ljudia.no and see if they'll send them to Ireland.

Other places you can try is:

Netherlands: Zelfbouw, Professionele subwoofer, bas- midden en coaxiale speakers - P. Audio HP 10W 10 inch bas - midden speaker 100 W. - LWA Webshop voor geluidsapparatuur

Greece: P.Audio HP-10W Woofer

Sweden: HP-10W - HIFI KIT

Russia: ????? ?????? | P-Audio HP-?????
Russia: P.Audio

Of course there's a few Aussie dealers as well but that's hardly interesting for a European user.

Thanks Saturnus, you're a legend!!
If I can't get the HPs, what would you recommend...use Emminence Basslites or build a Boominator mini?

They're not intended for magnet-to-magnet mounting. There'd be no point as there's pretty much no stray magnetic fields that needs to be tamed on neo drivers. Note that you need p.audio PHT-407N tweeters as well. And that it's highly recommended to use a miniDSP and 4-channel bi-amping with these drivers.

The driver for the mini is not just out of stock. They won't be produced anymore at all.

Thanks again Saturnus.
I was hoping to keep it simple and low cost for my first attempt with HP's and Piezos.

First of all, thanks for all your work Saturnus! Insanely helpful and inspiring thread, which I've actually read through cover to cover twice now, though the first time it was only a few hundred posts long.

Awesome! 🙂 May I just ask, where and how did you place the amp and battery? I thought about glueing some shims on the inside of the metal-plate and screw the amp there, but then there's probably some simpler way to do it. Haven't thought much about the battery but I do know I want to be able to take it out of the box in case it needs to be replaced etc.

Also could anyone suggest someplace within eu where you can find a cheap-ish lifepo battery 12v/4-6ah and matching charger? I know I've seen plenty of links to battery retailers in this thread before but now when I'm actually about to order one, I can't seem to find them.

I'll hopefully start building my qubi tomorrow, got to try to remember the camera so I can contribute with some pictures aswell 🙂

Half Boominator with S2010 and PHT-407N

Hi all,

Thought I would share a half-boominator build my friend and I did a couple of days ago. Here's a link with photos:

Half Boominator - Imgur

It's a 44x32x24cm (17.3"x12.6"x9.4") cabinet (28L internal volume) built in 12mm laminated plywood with two Eminence Basslite S2010 woofers mounted magnet-to-magnet (touching the internal bracing) and two P.Audio PHT-407N horn tweeters. The speaker is finished in "flight case" style with extruded aluminium angles and stell ball corners.

The amp is a Hifimediy T1-M TK2050 9-24V, which is mounted directly on the inside of a steel plate screwed onto the side of the speaker. The amp has a onboard pot-meter, which doubles as on/off switch. The 3.5mm mini-jack input is wired with resistors to make a stereo-to-mono summing. This means the two woofers share the same enclosure and play the same summed mono signal. A DC input socket is placed next to the mini-jack input where a battery can be connected. So far we have tried with both a 12.8V and a 14.8V Li-ion battery and had great results.

I'm sure this thing plays nowhere near as loud as a full-size Boominator, but with its tiny size and weighting only 10 kg, it's quite an impressive little thing! For most gatherings in the park, it plays louder than you would need.

All in all we are very happy with this speaker! 🙂 I would like to say thanks to Saturnus and everyone for this inspiring thread, and for helping out with the some questions we had for this build.

Nice job Soren5
Could you give some more details on how you wired the amp?

I'm seriously drawing a blank getting my hands on some HP-10Ws.
I've tracked down three but just need one more!

Saturnus.
Are you saying that if I go with the Basslites I'll have to use the PHT tweeters not the Piezos?

Why don't People use PU glue? Solid as hell and last for a long time. Vinter lim will be hard as glass over time and krack.
PU glue will also expand a bit and fill small gap. And it's water resistent.

Actually don't matter too much if you use PU, PVA or epoxy glue. As long as you're using the right type of glue for the right purpose. In terms of strength in their intended working condition they are more or less similar.

PU glues are best if the joints aren't completely straight and small holes needs to be filled along the joint.

PVA glues are best if the joint are completely straight.

Epoxy glues are used when you glue construction grade plywood (filmed plywood). It chemically bonds to the resin used in the plywood itself and the coating as well. I prefer epoxy glue for all purposes but it is difficult to work with for a novice. And special care must be taken due to it's toxicity.
