"cheap soundboks" portable speaker

Sigma studio is used with Analog Devices DSP, like for instance ADAU1452.
MiniDSP is it's own thing.
If you're in Europe it's probably cheaper (and easier) to get the t. racks 4x4 mini or the more flexible version with some small amps amp built-in.

If you want a more powerful amplifier or you need more DSP power there are other solutions to consider, not sure what kind of budget you have.
 
Thank you, I guess. I try to make a point out of not knowing anything, I mostly get by using willpower.

In case you haven't thought about it:
If you just want to adjust your sound a bit you can use any kind of EQ. If you use a phone as the primary source of music there are some apps that can help you measure the sound using the built-in microphone, and some other apps that can help you adjust the frequency response.
Personally I use "Spectroid" for analyzing and "Neutralizer" for adjusting the sound, but there are a lot of different solutions.

A proper amp with DSP would be clearly superior, but sometimes we have to make the best out of what we have at hand.
 
I have built a Boombox with a Fane Sovereign 12-250TC I have it in a 51 liter ported box (originally sealed) tuned to 45hz and it sounds really nice with an insane amount of bass, it's also super loud, I haven't tried it's full potential yet but I would assume atleast 120dB as it is now.

Here it is, I plan to add a tweeter to it at some point since it's just a prototype really.
