I just need circuit for act, cross. with fet's or tubes. Those i used with IC's was bad in mid-high region
for low bass for now i will use push pull
for mid-bass SE topology with tube gain stage
for highs also SE - tube gain stage
Im affraid only about setting gain and phases
any suugestion about tube act cross. circuit?

Do you have experience with active crossovers? What are your impressions if you use or you used such a approach? I mean about active setup.
Yes, but actually, I would need to replace my appliance with something better. What J-FETs are you having?
I dont have any J-FETs yet. First i like to find some circuit with particular FETs and try to buy them. Im not good in projecting circuits, so im looking for circuit just to copy and implement it.
Since active crossover + amps + speakers consist a single system, designing it concerns more the speakers design field, rather than simple amplifier design. We must adopt, that speaker design is different field, where one must possess appropriate experience, know-how etc.
Understanding this, I do not consider it practicable to play with crossovers. With good speakers, 10W of high quality output power is enough for home listening.

I know that but i have cheap speakers Wharfedale Diamond 10.4 450EUR, using tube preamp, one tube PCC88 for gain stage and one 12BH7 in parallel like catode follower, the next stage is SE PF99. Before i moved in Poland i had same amplification but with B&W 602S3 (also cheap). In general i like the sound of PF99 because no matter of speakers it sounds greats. According you, it would be the best to buy some kit speakers with known parametters and implement it with PF99. I dont have an oportunity to spend money for some expensive exotic kits, so im trying to get the best from that what i have.
Of course, i prefer single ended topology for active crossover. Your power supply will feet excellent. Thanks WuYit 🙂
But now i need a circuit for active crossover which will feet with power supply like this. I wont be so not polite to ask for circuit, ill try to search on net again.
Thanks again
great !!! I will need some time to undersatnd your circuit. Is it yours or you find it on net?
I think its Butterworth type of filter or im wrong? I will try to use it for 6dB and to increase the frequency to 140 Hz because i have to, the distance between drivers is for 140Hz, maybe 70Hz could be an option also. You are using workbench software?
It will be my pleasure to build your design for crossover and PS also.

The cutoff frequency for the sub bass and the bass-mid driver should not be the same. Please don`t worry about it, 100 Hz will be fine. We can expect resonances in the area.
