Review: Great quality, Nice adjustability of the tweeters, very large (perhaps to large). - These work great and the ability to reduce the tweeter output by as much as 6db is crucial in building a system where you can hear the sum of the drivers acting as one instead of each individually. The do not add any noise into the system, instead they did add clarity and tone separation making the stereo far more pleasant to listen to. If you have a high end amplifier and speakers, you will likely get a nice result, these will not take cheap speakers or amps and make them sound like expensive high end components. I do note that there is a top review that states there is a ceramic capacitor on this crossover, this is not true. There are resistors that attenuate the tweeter and provide some impedance matching. This is a very common practice and in the case of this crossover, allow for a reduction in how "bright" one driver is over another helping to compensate for instances where the drivers aren't evenly matched. Overall, its a great product.
Review: So far so great - I just put these in 2 days ago, after looking at them for a little over a year, and oh my gosh what a difference!! These are so great the shut those damn tweeters down so perfectly it sounds like I put whole new speakers in!! The quality of mp3 music (from your favorite app) is so much better, CD's sounded fine before and still great (because nothing is as good of quality as a CD) SERIOUSLY if you have after market components with aluminum dome tweeters and no audiophile crossovers these are a must have, you will be so happy with them and yourban ears will thank you ( if they could talk)

## Questions & Answers

**Q: What does -6db and 3db and 0db mean?**
A: This is how much power the crossover attenuates, or "absorbs" before it goes to the tweeter.  Every 3dB that a sound is increased or decreased requires double or half the power respectively.  So, 0dB allows the full power to hit the tweeter... lets say it's 50W.  Most of the time, the tweeter will be way too overpowering and loud in comparison to the rest of the system if you run it at the same power.  Therefore, most crossovers allow for attenuation of the highs to balance the system.  In this case, connecting the positive lead to the -3dB will reduce the power from 50W to 25W, providing a more balanced sound without having to turn down the gain on your amp.  The -6dB just reduces the power by half again, (12.5W in this example) and so on... hope this helps.

**Q: I need the true Rms rating for this product before i purchase it.**
A: I wouldn't put more then 125 watts through them.

**Q: How does power go though crossovers? If your sending 100w to it does the mid and tweeter both get 50 watts?**
A: It's not quite that simple. If you were to wire a woofer and tweeter together without a crossover, they would each get 50w, much of which they aren't designed to play, so there's a lot of waste (and potential for damage). With a crossover, the woofer gets the low frequencies of that 100w, and the tweeter gets the high frequencies of that 100w. So if your amp was sending 100w of bass/mid, the woofer would get 100w (minus a bit due to ohms law, obviously), and likewise for the tweeter with high frequencies. Therefore, you'd still want to run speakers rated for the full output of that channel on the amp.

**Q: Can I mix a 4-ohm tweeter and a 2-ohm midbass with this crossover**
A: You might be able to. I have 3 ohm running through it, with both tweets and mids

### ⭐⭐⭐⭐⭐ Stop looking & buy these
*by A***R on September 6, 2025*

If passive crossovers will help your system sound great, these are the crossovers you need. Well-built, well designed, well engineered. Many, many crossovers look and feel like toys. These crossovers are built like a quality amp, with screw down terminals that are well-labeled. It's important to me to help a fellow audiophile make their crossover selection, and every word of my opine is true. I left this review, even though my DSP made them redundant and I returned them. I almost kept them, just to look at them.
