I am busy saving and gathering materials for a big project, in the meantime however, I decided to do a "small" project to use the speakers and Bluetooth D-amp I had bought years ago. Also, using spare wood laying around to be cost effective.
Not suppose to be "HiFi" quality, but the results I am experiencing from the speakers and the D-amp is quite satisfactory - the loudness/amplitude is excellent and don't hear/experience any reverb/echoing, i.e. songs sound like they should - crispy and clear.
