Would it be possible to use à bass treble circuit without losing audio quality ?
I've also found à shop in Belgium to deliver the p audio hp 10t( these drivers are hard to get).
In à couple of weeks i'm going to start building my qubinator .
Hey, nice to know i am not alone anymore

Sure it isn't max 6 weeks? I usually get stuff form ebay within 3 weeks, even from china. It will also take you a while to do all the woodwork, so should be good timing.

Without knowing allot about amps, i am guessing that adding bass and treble will draw more power, and may result in quality loss. Please correct me if i am wrong.

If i can give you some advice, stick to the original design with 9mm ply. Unless of course you want to spend some quality time with your router...

I just received the battery a few minutes ago, and have more or less finished the woodwork. So now i just need the amp, and i am good to go

Good luck with it.

No. You can't use a 4 cell charger on a 3 cell battery.

I have finally got round to building the Qubinator! I got a Swedish friend to import the P.audio HP-10T's, but I am still waiting for battery and amp to arrive from China, before i can glue the whole thing together.

Anyhow.. I know you guys like photos, so here's a couple of the project so far.

Why did you cut these cirkel's on the side and at the botom.
When I look at Saturnus his design in sketchup they aren't present ??

It's discussed a little earlier. Kasper Jack is using 14mm plywood instead of the intended 9mm. Hence some of it has to go.

Okay thx.
Saturnus what do you think about a tone control circuit in the qubinator or is it overkill.

I know nothing about battery chargers.. How about this? If not, then which one of the chargers on the list you linked to earlier, would you recommend?

Nearly finished my Qubinator build, just missing the electronics now. First of all, will this charger work with my batteries?

I have spent all day trying to make a wiring diagram, but can't find a solution
I have bought 2x 12v batteries, a 3 way switch with 2 circuits, a fuse, a 12v AMP and a 24v AMP. I want to connect them so the 12v amp is powered by the the two batteries in parallel, and the 24v amp is powered by the batteries in serial. only one amp must be switched on at a time. I can't figure out how to connect it all together, or if it is even possible with that switch. Do i need to get a switch with more circuits, or is it somehow possible with this one?
