For 20-40 euros, this driver is the right choice. It has very good and powerful sound and produces frequencies that a decent driver at twice the price would never produce! I doubt the 100RMS given by the manufacturer because with a decent capacitor or a decent crossover it can easily play at 500w. On the downside, this particular driver and generally this series from the company has a slightly 'muddy' sound, and I noticed this at low volumes where this usually happens and I perceived it as a 'bad' midrange. I believe this is due to the magnet's poles, which are of average quality. On the other hand, at high volumes, it literally breaks eardrums and, due to the high power, plays more clearly. In general, as a replacement, it is very ok (in terms of sound and performance) but certainly, even for a professional, it can be a temporary solution. Now, for home or amateur use, I recommend it with my eyes closed because it will make you proud, just always with a crossover or capacitor.

Satisfactory driver for replacing a speaker that no longer has spare parts available. I haven't tested it yet to see its performance, although I doubt the manufacturer's claim of 100w RMS power.
