These do exactly what they are suppose to do. That being said, when using these at max wattage, they should be mounted to a heat sink, and may need some airflow.

Very good quality resisters and they test better (smaller) tolerance than claimed.

Decent resistors, the issue is longevity and heat. These get a lot hotter than most resistors. So hot in fact that when you solder wires to them, the heat causes the solder to melt and if you didn't tie your wires on they will fall off. However, after a few months, the wires fell off anyway.

オーム数の小さいスピーカーに小さい入力を制限したかったので、4オームを取り付けました、音割れがなくなり、バッチリです。もう少し落としても良いかな?と思うので、その時は直列で追加しようと思います

habe mir 2 Leistungswiderstände als Lautsprecherbrücke bestellt.Für meinen Anwendungszweck mussten die Widerstände auf einen Kühlkörper montiert werden.Die Plananlage der Widerstände ist gut, aber die Beschriftung löst sich sobald der Widerstand mit Reinigungsmittel in Berührung kommt,darum ein Stern Abzug. Zum Anlöten der Lötfahnen wird ein etwas stärkerer Lötkolben benötigt, da die Widerstände die Hitze gut ableiten.Toleranz war bei meinen beiden Widerständen sehr knapp an den 4 Ohm.Preis-Leistungs Verhältnis sehr gut.
