First day of building:

Fine pictures. What camera? (The kind of color and the feel of the crispness are of the style I like.)
And have you thought about using a line-level crossover?

Thanks, it's a Nikon d700 and Sigma 20mm f1.8 on these photos. Here's my photography portfolio btw. Antti Hakala: photography
I'm using the crossover supplied in the Visaton PA diy kit. Can't go wrong with it 😀

Nope 😉 I see. Line-levels are a lot of fun though - suggest you check it out when everything is playing well together
And that's not the first time I really like pictures out of a Nikon! Thanks for the link ...
End of building day 3. I used a lot of router to reduce weight.

Tried how it sounds. Hole on the upper left is for the battery compartment.

Here's my fancy tools and working environment ;D

What are you doing in my garage?!
Oh well, some things are global I guess ... There is only one garage blueprint, the ancestral plan ..

Haha lol 😀 Here's a quick plan for the carrying leash:

I think I'll go with polished grilles. I'll sand the paint away and use autosol to make them shine! 😀

Quick cellphone vid, it's actually working already 😀

Today I made the carrying handle. This handle is mainly for the looks and it will be mostly carried on shoulder with a help of leash. So let the photos speak:
Here's the basis for the handle. It's 20x20mm aluminum with round corners:
Cutting plywood for the parts which attach aluminum to the box:
Can't have enough clamps!
Wooden parts are now finished:

This is getting pretty serious looking. Thanks for allowing us to follow the process – very inspiring.
Thanks for yourself! Here's size comparison between my Ghettoblaster V2 and Megablaster. Megablaster weights 4kg so far. V2 has 4,25" mono bassdriver and reflex port behind the other fabric grille.

If/when you do another one, consider using a passive radiator to extend the bass response.
Takes up next to no space in the box (unlike a port), and may also be lighter than the cutout space that would have been reserved for the wooden cabinet.
PS great looking blaster.

Thanks for the idea, these drivers work best in sealed enclosure. I think reflex or pr box might reduce the power handling. I might try pr design later with new project 😀
