Hehe, I just realised that you live in Copenhagen and the total price of the tweeters and shipping would be 260kr to Denmark, so I thought it was just as good to just get 10 and maybe sell the last of them at some point

Yes you are probably right. We would probably only save ~25kr each by sharing the shipment.

Haha lol...well if I look op shipping it returns 'Forsendelse'...so naturally I assumed that it is called shipping cost?

I'll get 10 myself. Maybe post on Roskilde forum if anyone is interested in buying the other half.

It's always a good idea to an extra in case the unfortunate has happened and there's a bad sample among them.
Hi Saturnus - I would lige to buy the last 5, if they're still for sale
Think it's time for a upgrade to our old festival-stereo.

You're in Copenhagen? If so then yeah. Contact me on PM.

I was talking to someone in PM about you using 4x8v solar panels in 2 series pairs in your first Boominator, but I can't recall if there were any problems doing so? You've talked about 12v amorphous panels in most of your posts..

If i hook up 2x8v solar panels in series to 3x7.2Ah SLA's would that be okay even if the panel is rated for 8v but can go up to 9-10? Would a few diodes be necessary to lower the voltage?

There's a difference. Those 8V are open voltage. A "12V" panel has 16-17V in open voltage, so it's the same thing. To have 2 in series. Just remember, it's the open voltage that counts as solar panels are constant current sources so their actual voltage will depend on load.

Ahh in the description it does say:

This unit is rated for 8V open voltage and 650mA short circuit. We actually took a random unit outside and measured 9.55V open voltage and 550mA short circuit.

So I guess thats fine then! Awesome..

Ahw.. shoot! I'm too late to share a package with someone. Anyway. I live in Copenhagen if Wilcken changes his mind, Saturnus. And I would gladly buy 4 off of you.

Otherwise, if anyone wants to share a new package I'm up for that as well
