I see that those are two different N channel parts with different
current and voltage ratings.

The 2sk725's voltage and current are quite suitalbe for building
a number of the Zen amplifiers, I think. The ones requiring two
N type Mosfets per channel.

The 727 has a 900 volt rating with a 5 amp current, and I imagine
it could be put to similar use if you like.

:cool:

Agus,
2226G...for jazz:eek: I'd personnaly advise 2235 or 2234
they are more commonly used in Hi fi applications...the 2226 is a PA woofer not really for hifi applications ...unless you consider changing the spyder and suspension for softer ones...,
I tried it already...a pass 30w will drive it easily, the problem doesn't lie there...this speaker has a heavy cone, with cone breaks quite high around 1K2, making the mid range a bit hard to cross-over...as well it can be fitted in small volumes, but with low output under 70HZ...
