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 optimal performance)
- 24 biasing resistors (matched to the JFETs 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'
I go listen... Dirk
Very nice PCB and great analog xover with excellent dynamic, detailed and clear sound. Absolutely quite with no noise at all with 24 Vdc regulated PSU.
I build it for a friend of mine and for me. The results are fantastic. I compared it to the MIniDSP nanosharc board for driving Borberly amps Sonus Faber Cremona Auditor M as satellite and 2 x Ripol for the range below 100Hz. There is no point of discussion even if you use the Linear Phase and room correction function of the nanosharc. The analog Crossover is far better. My friend compared it to a Reckhorn Crossover which is a Operation Amp design. He got the same results I did. It´s a great kit.
i got this really fast. I haven't opened it yet as I'm waiting on Digi Key with a few back order items. This is the fourth item I ordered through the store and I've never been disappointed. I'm a novice at electronics, but these kits make it easier for me to enjoy this hobby. Of course it's the members generous help on the DiyAudio forums that makes this hobby so enjoyable for me. Thank you DiyAudio members.
Good idea, top quality.
diyaudio store ist best.
Cons, eu warehouse is missing. Vat + shipping is same price as diy-kit
