It does make a difference to optimise the crossover frequency and use high quality components. The treble is outstanding now, very pleased with the sound. Need to listen to this setup for a while before tweaking the crossover:
Crossover finished
Ale,
Small value ERO KP-1832 film/foil as bypass ???
Rajko, yes a 22nF KP1832. That is what I had in stock. It sounds good. Would you recommend a higher value in your experience?
Thanks
Ale
KP-1832 is a super capacitor, best film / foil ever, imo.
No no higher value. I recommend even lower value (5,6-10nF).
Unfortunately, I only have 75 nF of KP-1832 and It is too high for bypass.
I use russian teflon 5,6nF for midbass and Siemens 8,2nF styrene for tweeter.
But you have fullranger, maybe he demands something a little different.
Ok. Best to listen and tweak later. So far I’m very happy with the sound. Will measure response before doing any further changes
Excellent! Any measurements?
I measured electrical response on the bench and was very accurate, but this means nothing other than I connected the crossover as per design 🙂
Running a proper test requires moving testing gear down from the workshop and I’m struggling with time at the moment. Will definitely do the FR test as I’ve done prior to installing this new crossover. I can then make comparisons and further tweaking
Cheers
Ale
Ale, I will follow your work. I need a new pair of small speakers for a weekend house. Inexpensive FR with woofer-assistant is my hot idea now. 12-13kHz is an upper limit to my ears 🙂
Please, if you can, measure total impedance of speakers in entire frequency range. I think it is (perhaps) most important thing for our SET amplifiers. Necessary to make overall impedance minimum of 8 ohms and up. Frequency shares are distorted where impedance is less than 8 ohms
Hi Ale.. i have the same fostex full range driver in back loaded and FT96H.. may i have the xo schematic? Best regards.
