Depends on how long it would take for them to get here 😉
If it's soon, then I would probably be interested in 4 pieces.
And I'm guessing when from India, then it's not going to be so soon 😀
I dont think 12V LED´s exist, not without a resistor somewhere? Single LED`s that is, not Matrixes. The LED runs more likely on about 3V. But I been wrong before.
Arbitrage:
Here is how i did it. I sanded of the grooves inside the box and used only the two screw-holes in the back to fasten the card. As you can se it needed some kind of bricks and plastic washers to keep it in place.

No not yet. Haven't got the time for it yet, but when (and if) I find some I'll post it here!
Im going to use the Goldwood speaker and a Piezo horn. The horn is going down to 1.8 kHz and Im a bit worried by this. The Goldwood is spaced to 4000 Hz and and I fear that this will be problematic. So, if any, what do I need to think about? Maybe a HP filter for the tweeter? Or is it beater to get new tweeters and if so every suggestions is appreciated. I have looked up the models previously discussed but thy are both hard to find and specific for the HP-10W.

This is our boombox for Roskilde this year - we have gone for a different look 😉
An externally hosted image should be here but it was not working when we last tested it.
The Goldwood cuts at around 2.5KHz, and the "1800Hz" I will bet does about the same just the other way. There aren't that many different piezo designs so they'll almost all be the same. There can be massive build quality differences but that's about it.
So which would you recommend for the Goldwood's?
Would using these:
| IMG Stage Line 110480 |MPT-005 Speakers » Piezo Tweeters
Be a horrible mistake since all tones from 2,5KHz - 4 KHz won't be played, and thereby find something different?
Just to be on the safe side here. There seams to be 2 different GoldWood GW-1058 but i can only find one of them on goldwoods homepage.
Is it
Goldwood GW-1058 10" Pro Woofer
or
Goldwood GW-1058: 10" 200W "Huntington Series” Woofer, Discount Prices on Goldwood GW-1058: 10" 200W "Huntington Series” Woofer
?
I was under the impression that the later was recommended by Saturnus but the first one also would do the job.
Its a bit troublesome when the model name is exactly the same.

Does anyone know if these batteries would be good for the price?
12V - 12Ah Deep cycle : Batterishoppen: Holdbare og billige batterier
Or is there anything better
EDIT: They're sold out 🙁
Can you recommend a battery for a "crappy edition" boominator 🙁 🙁

I bought 2 of these: Yuasa NP7-12 - 12V - 7Ah (F187 4.8mm) -
Free shipping if you live in Denmark.. These are quality batteries, and they're not that expensive. I recommend them. 🙂
or yuasa NPC range if you want the (better quality) deep cycle variant 🙂
depends on the budget! I have also had very good experiences with the NP7 and NP24

I have a few battery questions regarding the Boominator..
1. Can you play music while charging the batteries with solar cells?
2. Is it safe to smoke near the Boominator while it is charging?
3. Is a charge regulator needed for my batteries? I have 14Ah in total and 10W solar panels?
Thanks in advance

Thanks for the advice 🙂 I'm on a pretty tight budget, so i bought 3 of these instead of the NPC..
Saturnus, I've seen you recommend different values of resistors to different piezos. I was wondering if there's any way you calculate this with an equation?
Afaik, piezos are different (with different capacitance values) and a crossover with a resistor is unique to each piezo. Therefore the capacitance should be measured.
I've been looking for online calculators but have not found anyone for piezos in particular. That's why I'm asking here now

1. Absolutely, with a 10w panel and no clouds you'll be charging the batteries fine even at full volume!
2. No problems!
3. Nope its not necessary.
Its hard to mathematically calculate what sounds best to your ear 😉
Resistors cost less to nothing, so its no problem trying different resistances.. Trying different values and listening to the results is better than trying to calculate 🙂
Of course this is what you could do. But I'm looking for an easier solution than trying out 10 different values. That's a lot of work compared to just putting some numbers in a calculator and then getting the right answer.
But I guess you're right - sound is hard to calculate precisely.
