An 80 amp rated PP film capacitor is pretty much ideal, although 1mF has a 3dB roll-off at 20Hz for 8 ohm load, 40Hz for 4 ohm load.
somewhere at delite article said:
1,000 uF of polypropylene capacitance will get you down to around 30 Hz or so,
and larger values will get you lower, if you can afford them.
is that mean big MKP caps has better bass than 10.000uf electrolytic caps?

As Zen Mod said, it's in the physics and numbers. Or, there is no replacement for displacement.
Do not fear the electrolytic. You can parallel an electrolytic with your film to get the 10mF.
I did that with my monoblocks and they sound terrific. I used a 10uF motor run (film) in the output paralleled with a 10mF Nichicon LKS electrolytic.
I used a 10uF motor run in the input paralleled with a 1uF Panasonic film.

thanks for your info..
btw i want to build with 2sk180 parts, but with TO-247 for ccs
so i can put them in one nice pcb, bent to Lshape alum sink.
are there any ixys TO-247 as good as or even better
we can use, rather than IXFN 140N20P which is SOT-227B..?
according to tracking site of my local post , it seems that Singing Bush pcbs I ordered from our Chinese Brothers are finally unchained from Customs , after 27 days just laying there
bloody bstrds
I was so thrilled tonight seeing that , that I drew Babelfish F7 schematic
go figure
I mean - proper Babelfish - damn different to original one
