As long as it worked, it had a nice sound and brought life to 2 old speakers! Unfortunately, the manufacturer's choice to attach the heatsink with double-sided tape was condemning for the circuit board... after just 10 days without playing for many hours, it gave up. When I opened the box where I had placed it, the heatsink had detached and the circuit board had burnt components. Simply unacceptable!

For the money I paid, I can't complain! Very nice sound combined with a crossover, it has enough power, it must be as it says since I have installed 2 speakers 230 watts total and I can almost say that it "fills" them. The only negative thing I have found is that at around 85-90% volume, the tweeter produces a sound as if it is being overpowered, but it's not that because I have installed 3 tweeters of the same type and had the same results. It's a minor flaw as anyone can easily connect other speakers together (just a few jack to jack cables and a few male jacks to 2 female jacks are enough). It's an excellent choice if you have some old speakers like a subwoofer from a home cinema, for example, and you have no other way to use them. With 30-40 euros, you can build a speaker that has nothing to envy from some partybox speakers of companies that cost 200-300 or even more euros. I should also mention that mine is powered by a laptop power supply.

I have had it for 5 months and it is relatively good. I use it at 8 ohms usually because it struggles and cuts off from feedback at 4 ohms. It has good sound until it cuts off. All class D amplifiers have a cut-off point and if they reach that intensity, they cut off something that I don't really like, especially when listening to music at high volume and there is a sudden increase in low and continuous bass
