HIFI Passive Crossover
1 Pair Adjustable Crossover Point Volume Adjustable Crossover for HIFI Horn Super Treble Unit Full Range Speaker
This is an ideal three-stage adjustable crossover/6-segment level-adjustable/third-order supersonic crossover. The level uses a precision resistor to form an L-shaped attenuation line, which ensures impedance stability. The frequency division parameters are as stable and reliable as textbooks, and crossover level is adjustable in six stages. It can be connected to any 8 ohm super treble unit, even if it is high sensitivity super treble unit, it can be attenuated to a reasonable level. Choose to use step switching to ensure that its balance is left and right at all times.
In particular, it is important to note that the sensitivity of super treble unit is preferably about 5 dB higher than the matching speaker to complement the speaker!
If the super treble unit is 4 ohms, a 3.9 ohm 5 watt non-inductive resistor can be connected in series, and then connected to the adjustable crossover, it can have the same effect.
