... And an open question: If you're not supposed to use screws, can you then use glue and screws and wait 24 hours for the glue to comepletely dry, then remove the screws and subsequently fill the holes with polyfilla?

What is recommendable?
I use glue and screws - and plenty of them to hold it together.. Just remember to predrill a hole of about a third of the screw diameter to lessen the strain on the plywood.. Also countersink the holes to its easy to fill them out with polyfilla or similar.. The countersinking is actually a necessity if you wanna make it look nice

A nice explanation. Thanks for the effort with the pic and everything. Seems like I have done it correct though. I was just doubting my own knowledge

Can anyone give me an estimate for how louder the Boominator Signature is compared to the Boominator Mark II?

Just before plunging down all the money for the Signature part, as they are really expensive compared to the Mark II build.

If you take it over the standard Boominator with an amp6b, and the signature is made with a 24V amp then it will be 8dB louder. +2dB from more sensitive drivers and +6dB for 4 times the output power.

It also means that it will only be about 2dB louder than a standard Boominator with a 24V amp. The aim in the signature is getting close to audiophile sound quality in a portable speaker.

Hi all,

My first post here - thank you for this helpful thread, a lot of good information here.

Considering making a 'Boominator' aswell, and I think I found the right parts for the project - please help me out, and tell me if the parts will work out together.

2 x Tweeters (Piezo Horn Tweeter PT-1016 | BN100287 - Elektronik Lavpris ApS) - 78 DKK
1 x Amplifier (Amazon.com: Lepai Tripath TA2020 Class-T Hi-Fi Audio Amplifier: Electronics) ~120 DKK
1 x Solarcell kit 10W (Solcelleanlæg - 12V) - 895 DKK
2 x Subwoofers (P.audio HP-10W - Ljudia - Multimedia Hemelektronik Karaoke PA anläggning DJ utrustning Ljus utrustning) ~ 700 DKK (any suggestions to cheaper alternatives?)
= 1793 DKK

As battery, I have an old one from last years festival - 12V, 65Ah I think. One of my biggests concerns is the solarcell kit - will it be suffiecient enough, for such a big battery?

Im thinking about adding an old laptop aswell, but would it consume too much power and shorten the play-time a lot?

Hope y'all can help me, thanks!

@Sive. Welcome abroad. Are you sure that battery from last year is still working? If you didn't recharge it after the festival, and it's just been stored away, it's probably completely dead.

There are no alternatives to the P.audio HP-10W except the Goldwood GW1058. Those 2 alternatives are in a league of their own in regards to sound quality at the price point. Also note that other drivers might not have suitable parameters to be used in a Boominator.

Thank you for your quick response.

Okay, so either the P.Audio or the Goldwood.
What about the tweeters - do they look OK?

Any comments on the solarcell kit?

(Seems like my previous posts is gone now?)

Thanks for the answers and help!

In that case I might as well go for the AMP9 with the NTX3711 Piezo Tweeters and HP-10W, right?

The audio we are going to play will, after all, be compressed MP3's or AAC from iPods and iPhones.

That's what I'd do really. The signature is really just a showcase for what is physically possible when you take the best possible drivers for the purpose and pair it with a high quality amp. Basically a state-of-the-art build.

Oh, and did I mention that I also now recommend the miniDSP as active crossover in the signature?
