Portable Battery 2 way speaker

In an ideal world, the vibration of the cabinet panels wouldn't contribute to the sound of the speaker. Some may call this colouring effect "character", but I don't feel the same.

   I'm not one for just doing stuff for the hell of it, but if I can get a small gain for a small effort and a small expense then I'm all up for it.

  If you use bitumen panels on all 5 (excluding the baffle), I'm very confident it will result in a better sounding speaker.

  Do take into consideration that adding this to all the panels will reduce the effective internal volume and therefore raise the cabinet tuning frequency. You might want to calculate the differnece before committing!

Try using a tone generator app and feel each panel at various frequencies. There will be a couple of resonant peaks which, although can't really be eliminated, may be mitigated. I've found that these frequencies affect different styles of music to a greater or lesser extent.

 Using a tone generator can also be helpful when you apply pressure to opposing panels, as these are often the easiest to brace.

Sweet. If you see or hear an army green VW T4 dropping some basslines then say hi!

I want them fitted toward the front, on the side walls, nearest the tweeter as possible really. Just to keep it all away from peoples fingers, should someone else open it to change the battery or that. The battery holder will then be fitted in the middle nearest the door end.

Is there any downsides to that at all? With the tweeter having the big magnet on it. The tweeter will be the last thing fitted but here is a photo just to show you how it is, and so i can work out roughly how things will go.

There is about a 4cm gap between the tweeter magnet and the tallest part which is the amplifier.

Heres a photo just so you can see what i mean

Also the door has 2 holes in which are for air flow and also for your fingers to get in to remove the door. I got no idea how hot the electronics will get but thought its best to have 2 holes for air flow? Another reason thought to keep away from the holes incase of rain or liquid getting in. Chances are low but even lower with things away from there.

But yeh completely agree with you about weight distribution.

The holes can easily be blocked off on the inside if they arent necessary.
