Might be a dumb question, but if I build active 3 way speakers with a DSP crossover, will this amp handle a chinese clone bg  neo3 pdr?  it's 4 ohms nominal and I know this amp is for 8 ohm speakers.. but tweeters don't use much power right?

Incorrect, it works fine with 4 and 8ohm. 4ohm gets 120w!

Tweeters do not use as much power as woofer.

Thank you

Email me at folsom.jeremyh@gmail.com. The parts are all in the BOM, easy to order off of Mouser.

another dumb question about the 7297.. if I only connect one speaker because I'm only testing one speaker.. it doesn't break the amp does it?

Not in my experience, you should be fine.

These look awesome, is anyone offering a build service for those of us who aren't amp builders?

Sometimes I wonder if people are hired by advertising firms to post.
That was a quote too.

I literally have no idea what you're talking about.

But if you think Folsom has an advertising firm I think you're confused, very.

Prepped this little aluminium box on my kitchen table using a drill, handsaw and some sand paper.  :P
Now just waiting for the boards and off we go!

Cool looking box.  I started this thread 64 pages ago, and my Folsom amp is still sitting in a cigar box.   :oops:

 :lol: I'd say you started in the right end, though... Great sound from a cigar box beats no sound out of any box. Bought the BOM so just waiting for the mail man to slide some green magic through my mail slot.  8) And this thread is a really nice read!

If you cut a small slot between the binding posts + and - for each channel you'll get better sound.
