🔊 Crossover CRX 303W Passive Tweeter: Enhance Audio Quality with Precision Review

I bought these to replace a broken 10 channel amplifier in my 33 year old BMW 750iL. In front of the cabin there are tweeters, midrange and bass on the left and right. I use a 4x75Wrms amp in the trunk; the output of one channel goes to one of the crossovers. The cables to the speakers are removed from the old connector and screwed to the output ports of the crossover. The downsides of the crossover outputs are tied together, which is in keeping with the way the car ties up the downsides of the

As of December 2020, the box still lists these somewhat nonsensical transition points in four different places (see picture). I tested the outputs with a 4 ohm 5.25" coaxial speaker on my desktop and these are my unscientific conclusions based on my 40 year old ears: Woofer: 20-1300 Hz but still somewhat audible up to 12,000 Hz, Medium: 800-3200 Hz but still somewhat audible from 130-13000 Hz High: 3000-20000 Hz but becomes somewhat audible at 300 Hz Components appear to be quite robust and the

Just got to me and the quality looks great. However, the intersections confuse me. I've seen two or three other visual aids for intersections and they were all different, and so is mine. I wrote -20Hz316Hz -700Hz4kHz -1.5kHz20kHz on the boxes. I'm not sure about the gap between 316Hz and 700Hz. Seems I'm losing some of the tone there? As mentioned I have seen other crossovers and most commonly seen these "-20Hz500Hz -500Hz3kHz -3kHz20kHz" which have no break,
