class D, 70-80W, 8 OHM
In order to build a stereo 70W amplifyer for two 3 way speakers 70w rms, 8 Ohm, which class D amplifyer module should I buy? I'd like something like UcD180, easy to atach the module, so easy to build when you have everything bought.
Unfortunately, I think Ucd180 is too powerfull. Anything close?

An amplifier can never be too powerfull. It's small amps driven too hard that kills speakers (especially the tweeters).

The module can work with as low as +/- 25 volt supply voltage, so it's up to you have much power you wan't from the module.

ok, got it, thanks

And UcD180 produce 180 W only at 4 ohms, the half at 8 ohms, so it's just perfect!

thanks, meanwhile I've received a mail from saying that it is ok too.

I thing that I should also buy a SMPS400, they said ( that it is enough for 2 ucd180.
So I wouldn't have to buy a toroidal transformer, and the condensators and put them toghether and so on.

What tone corrector should I buy with this, in order to boost the bass or the high frequences?
