DIY Biamp 6-24 Crossover
The DIY BIAMP 6-24 kit is a stereo analog active biamp crossover circuit designed for high flexibility. Featuring 12 discrete Jfet buffer circuits operated without negative feedback, it offers 16 continuously adjustable filter elements in two low-pass and two high-pass filters with slopes of 6, 12, 18, or 24 dB per octave and various “Q” characteristics. It has flexibility not generally offered by crossover products have “textbook” characteristics, allowing more detailed tailoring of filters around the actual character of different loudspeaker drivers.
- 24 JFETs (selected for Idss and matched for performance)
- 24 biasing resistors (each paired to a JFET for optimal performance)

A great product - just what I was hoping to find. No complaints regarding the board that was supplied. Very good quality. I would like to weigh in on the discussion about supplying this product for Surface Mount Components. If the board were designed for surface mount, I would guess that there are many like myself that would not be inclined to attempt the build. Please continue with through hole products.
The 6-24XO gives you the chance to build an excellent sounding 2-way - active -crossover (stereo) on one pcb.
The kit includes well matched J113 - JFets for the buffers. No Opamps involved.
The pcb is of very good quality. Delivery was very fast (as well the german customs).
Great kit - your chance to go 'active'.....
This is a super versatile active crossover! Slopes from 6-24dB/oct.! Also a bandpass possible.
I used it to actively cross at around 2.5kHz for a 2-way speaker. Sounds superb!
PCB of great quality. JFets very good matched.
Delivery very fast from USA to Germany (although there is the Pandemia).Good job DIYaudiostore!
Thanks Nelson Pass! This is a great 'sound-machine'

This is one of those projects I thought I would never need. Since buying a pair of Full Range drivers, I needed a crossover to pair them with my subwoofer. I'm building a BA2018 preamp with the 6-24 Crossover integrated in the case, the PCB is small enough to fit in a small enclosure with BA2018 PCB. Best part of all, when I had a question on building the Crossover, it was Nelson himself who answered it.
Received my circuit board and transistors rapidly. Quality packaging. This is just a beautiful PCB, superbly laid out, component values clearly indicated, and it's plenty thick and stout. Very happy with this purchase. Can't wait to build. Just need some time!
Always in perfect condition! Great initiative and work from you! Im a Fan!
High quality board . Fets are well matched . Very happy with my purchase..
Looks good -- haven't built it, it's near the top of the list, so I think it will be started this year and finished in the first quarter.
