2 Way Crossover for Speaker, Universal 400W 2 Way Speaker Unit HiFi Home Speakers Audio Frequency Divider Crossover Filters

I'm using this passive crossover unit to split an amplified audio signal from a single 300W amplifier between the tweeter and midrange speaker drivers in a DIY outdoor PA style bluetooth speaker "build". Essentially using a passive crossover unit like this one allows a single amplifier to be used with both the speaker and tweeter driver in the PA speaker by passing only the frequency range that each respective driver is designed to reproduce. Sending the full frequency audio signal to a speaker that's only designed to respond to a certain frequency range, will quickly overheat the VC's and cause the driver to fail. This is an inexpensive option to separate or crossover the frequency range between two drivers, allowing a single amplifier to be used to drive multiple drivers, as opposed to using audio-source DSP to separate the low-level signal before sending the crossed over signal to separate amplifiers/drivers. (more involved/costly yet more accurate signal reproduction) This unit does what it's marketed to do, and doesn't sound half bad with the PA speaker. Even when running higher volumes, the conductors in the crossover unit only become slightly warmer than ambient. The high passed range has a +3db switch that "boosts" the high-passed range by 3db relative to the low-pass range for extra clarity, if needed. I didn't need to use the +3db, but it's there and it does work. Overall I am very satisfied with how the speaker sounds for this only being a passive crossover unit. It's worth mentioning that I don't recommend using a passive crossover unit like this to split an amplified signal to a subwoofer because it results in loss of woofer damping control by the amplifier, which has the perceptible audible effect of degrading the low end response significantly, especially at moderate/high power. For what it is this unit functions as it's supposed to though so i'm giving it 5 stars.

The description is gibberish. Looks like a 12db/octave crossover, but not enough relevant information to make a decision. I’d avoid it unless you’re looking for cheap and easy but you don’t care about quality.

This audio crossover for speaker systems is very well built and work well. The crossover has a good sound quality and will handle lots of power. I'm using this crossover in a 400 watt pa system and the sound coming out of the PA speaker is as good or better then the factory crossover. This crossover is much better built and the inductors have heavier wires then the factory unit which failed. This crossover is about the same size as the original unit so it fit into the existing space with little difficulty. So far, this crossover has operated at high levels with out any issues.
