Krell KBX crossover.
This looks to be the goods for a good 24db active 2 or 3 way, for $499!!! Only gripe I have about it, I would have much preferred to have dip switches to set the xover frequencies than predetermined set frequency card insertions. https://sublimeacoustic.com/products/k231-stereo-3-way-active-crossover Cheers George |
Be careful when buying electronic crossovers. Many speakers require some sort of wave shaping circuitry in their crossovers. Some specific electronic crossovers are designed specifically for a certain speaker and include the wave shaping circuitry. If you are going to buy an electronic crossover, contact the speaker manufacturer and ask them if that crossover will work correctly with your speaker. enjoy |
Thanks, Please read the discussion at the link below. I've tried to contact drrdiamond, but haven't heard anything yet. I really hope that there is someone who can help me. https://forum.audiogon.com/discussions/actively-bi-amping-b-w-matrix-800-s?highlight=krell%2Bkbx%2B Thanks in advance! Marc |
Seems to be 2 way stereo or 3 way mono. Lovely build if it were 24db slope I could give the resistors to change, unfortunately looking/reading this it’s only 12db slope https://www.diyaudio.com/forums/analog-line-level/332312-krell-kbx-crossover-info.html Cheers George |
I have Martin Logan Monolith III Speakers. I went from the passive crossover to a Martin Logan RCA input/output electronic crossover, then to the Krell KBX crossover that had the necessary wave shaping circuitry for the Monolith III speakers. A huge difference and much better. Excellent fully discrete crossover with external power supply. If you can find one that as built for your specific speakers, go for it. You will really enjoy it. I upgraded the woofers to the Peerless woofers and with my system, it is outstanding. one thing. The Krell KBX crossover does not have a power on/off switch. It is always on. Years ago, I found a strong electronic burning smell in my house. Some components within the Krell unit were burning. I reversed engineered the design and discovered the failing parts. But, today I unplug the crossover and plug it in when I turn all my other equipment on for listening. I've learned my lesson. I no longer leave my equipment on. I turn it on about an hour before serious listening. Anyway, you won't find a better crossover. enjoy |
The KBX is a superb crossover. I am using one with my biamped Divas. Unfortunately, modifying the crossover frequency and slope is difficult since Krell has no documentation. I have information for the B&W 801 speaker so if you are able to find a KBX and the crossover of the 801 is the same as your 800 you are welcome to the info. |
