@xidnpnlss I searched the internet for a Dynaudio 15w38, but as of now, I have not found any helpful info. To replace this with a different driver, you need this info at a minimum.
Very closely matching sensitivity of the driver
Very closing matching impedance at the crossover point (not necessarily stated impedance(
FS & QTS that will produce reasonable bass response in the same box....
I have only found 2 drivers that my best guess will work as a drop in, but without knowing the measurements of the Dyn, there is no way to tell for sure.
If you completely switch drivers, rather than look for a drop in, you can easily modify the crossover and get satisfying results.
I know that you are on a budget, I would start with replacing the burnt resistors,. On a hard budget, I would get the Dayton 1% precision 10 watt resistors (green) from parts express. Most likely, they are the only components burnt in the crossover. Confirm that and let me know. Start there.
