Oh sorry my mistake about the woofer.Having the woofer and the tweeter would cover a frenquency range of 50-40 000Hz am I right?

With 1 12V 7,2Ah battery, how long would it be able to power the system (2 woofers, 2 tweeters, 1 amp)?

Would still appreciate help whether I should put all elements on 1 side or split them.

What is the main reason for mounting the woofers on the inside of the box?
We have already established that the woofers wont be glued together with the new woofer dimensions, but rather glued to the middle brace to compensate for the lacking "9"mm.

Is the main reason the increased stability of the baffles or the physical protection they get or a combo? Or maybe some other reason all together?

I am still glueing the woofers together and just adjusting the width of the box accordingly.

I don't really understand this question because that is the best way to mount a driver, any driver.

I mean mounting them from the back of the baffle ofc, instead of "normal" mounting with woofer and grill screws from the front of the baffle.

By the way, I got the woofers and the solar panel today.
The woofers all work, just checked using one of my trends audio TA-10.1 amps to get a feeling of the sound output.

I have some questions regarding need for regulator or not.
The Sunlinq foldable 12w panel I have now has a max output of around 8-900mAh and Im planning on using the recommended 2x7,4Ah batteries in paralell. Do you think a regulator is needed or would it be possible to skip it?
The reason Im thinking about skipping it is to have a 12v cigarette female connector in the front or on the top of the boominator and charge the batteries through that connection with the external solar panel. And when Im not charging I could use the connector to charge the mobile phone or mp3 player that is playing.

The only reason speakers are normally mounted on the front in production speakers is that it's much cheaper to do so. Acoustically practically every speaker sounds better when mounted on the back of the baffle instead. It also looks far better.

In my personal opinion you wouldn't need a charge controller for this use.

Woofers playing, batteries bought, 12v female connector for panel mounting bought. Charging the batteries 1 by 1 now to max before i connect them. Ill give them another hit once connected in parallel.

I decided to go with 3 batteries after all, original plan was 2 but I don't want to have to rely on the weather for this years Roskilde.

Build progress:
No tweeters yet so no holes in the baffles for them. But the build is progressing nicely, so far so good.

Im planning on using glue on all parts except the lid (to be able to open the box up in the future). What kind of glue would you recommend?

Also how many screws have the rest of you used on each side (900mm side and 300mm side)?
