Hello,
Long version: I'm fed up with bluetooth speakers. Had a JBL Extreme before, also a larger one with handle (not sure the name), it is good for music like techno I guess, but that is not my taste. Both had poor mids. Than, I planned to modify my Dynacord Mosquito S boxes, create smaller, half boxes, but finally decided to skip that.
Than, I found an old box, a half Focal Poliglass V2 component set (after the first set failed, I was so stupid to buy Focal again, the iron core got rusted and stuck. One side was repairable, the other side not, it ended up in it's box for several years). So, I found this half side and decided to make a mid size, transmission line style speaker out of it. I'm very surprised how successful this became. It had mids, deep low, not too much, but accurate, tight and pleasing highs. Interesting, despite it is mono, it has space, it is living. ... driving with my single ended class A triode amp.
Than, I've tried with this : https://www.aliexpress.com/item/32891062619.html?spm=a2g0o.9042311.0.0.27424c4dog7218 . TDA7498 based, built in BT receiver. It has a good base, but the enjoyable mid and high gone. It is loud, but I rather decrease the volume, not up :-(
Now, I would look for a class D amp module, I would prefer a mono module what I can run from 18V battery packs (cordless power tool battery, Lidl parkside). Not sure what advertised power should I look for, but I think it would be about 40W if it would be a normal class B amp. (this speaker can handle quite high power). Do you have a suggested amp module, from Ali if possible, which could bring the nice sound back? Not with built in BT receiver. Another bad thing about this module I have, even the smallest volume setting is too high. I have a good receiver module, which sounds good too. More looking for an amp, mono, about 40W real, 18V single rail, but most importantly, what sounds the best from these cheap modules. On the other hand, I will not buy an x hundred EUR module for this project. I hope you can help me to find something good on Ali for me.
Thanks a lot,
JG
