The important bit is the voltage really. More current is basically better, but it won't make much difference considering the power handling of the speakers.I buy al ot of stuff on eBay. I searched 15V PSU and got this right away - https://www.ebay.co.uk/itm/15V-5A-FOR-TOSHIBA-EQUIUM-A100-147-A100-ADAPTER-CHARGER-PSU-LEAD-POWER-CORD-UK/22365701945

Hi,I think that will be okay. I would recommend 15V and 3A or more.

This is great, thanks so much for sharing the photo!

Awesome I think you're right. GxAmp is not a speaker manufacturer so I'm sure they are the same Hi-Vi (SwanSpeaker) drivers.

I asked I'd they can offer a better price for shipping and Dominique said customers would need to email for a price depending on their specific local.

A front baffle that uses the 'Skyline Diffusor' pattern might look nice too, I think. www.rpgeurope.com/products/product/skyline.htmlOnline calculator www.mh-audio.nl/Acoustics/DiffusorCalculator.asp

People sometimes add felt or cloth around a speaker baffle to reduce diffraction effects, reporting clearer details in the sound.'Speaker baffle diffraction' is the key term.

Oh bummer! You can also find them at Solen.ca

There is limited space inside after all the parts are added, I think Pi will be too big. I have seen some boards that can connect with Amazon Web Service to access voice control. I have not used them.

I often use Madisound but they dont advertise stock. I can ask if they would consider stocking, or perhaps have some in a dark corner somewhere.

Also, the B1S alone are tiny. Could fit in a padded envelope. Perhaps worth an email and a link to this project. Ask if they can offer a more affordable solution?

... perhaps adding a 'super capacitor' after the boost converter would store enough charge to smooth out dynamic power draw.

Thank you!

I did consider that, but unfortunately I don't think it is practical. The amp boards need minimum 8V and will work better with more voltage (dynamic head-room). This battery pack gives about 15V. 12V from a car outlet would be okay too.It might be possible to use a boost converter to increase the voltage from 5V to 12V for the amps but the very dynamic nature of the power draw would probably not suit such a circuit.However you can charge the battery pack from USB! Each battery is only 3.7V so individually they can be charged on USB and chargers do exist.

That's a compliment and a half! Thanks very much!

You need to use the bluetooth module as the star ground point, then the noise will be reduced.

That is very easy, will you build it? If you share your build I can maybe make a new DSP profile to match it.

Right the Fusion file is there so it can be altered. I would suggest keeping the 45 degree angle for the stereo tweeters though.

Thank you! As you like growing things you might spot the Korean Pumpkin growing in the background :)

I have some CSR8675 modules, but they will not switch to the aptX codec, they are stuck using SBC. Does anybody have an idea what's going on? I wonder if there is a firmware setting I need to enable? (P.S. the problem is not my phone, I can use aptX on other receivers)Thanks!

I also changed rset resistors which might have caused a problem. So go close, but not fully 2.5v

Just be careful not to go above about 2.4v. I went to the end of the potentiometer while machine was on and it damaged my PCB.
