powering PC speakers in a MAME cabinet

USB speakers will be woefully underpowered anyway.

To get the results you want, I'm afraid you are going to have to bite the bullet and find a way to get power to those speakers.

Another idea is to switch to a 12 volt speaker solution.  Car audio is 12 volts, you could get a small power booster or 20wx2 car amp and run it off of a computer power supply.  I still think you may experience noise problems from this (due to the fan inducing a whine).

You might just want to find a way to get power to amplified speakers.

I just found this at Happ Controls...

It runs off a 12VDC and I think it could be powered off of a PC power supply.

It's a little expensive (about $60) but would make for a really professional installation...

Cool!   They have the amplifer by itself...

$41.35 with enclosure
$32.65 without enclosure

 according to the specs... its max power is only a mere 8 watts.   I think most cheapie boom boxes have more power in them.

  you may want to reconsider...

  Imop... game sound is pretty important.  Clear, clean, deep bass, powerfull... : )  I may pop a surroud system in mine... not sure yet...

I did consider that but I want to keep my cabinet as close to original as possible.  I want to use normal cabinet speakers and I want it to sound as close as possible to the real thing. Cabinet speakers are usually less than 10 watts.  Some, like the 4x4 ones I'm getting from Bob Roberts, are only 5 watts.  So, hey, it might sound crappy but the real thing sounded crappy too.  I think it's a more "accurate" emulation of the whole arcade experience.


I can always "upgrade" the sound system later if I decide I want something better and more powerful.  If I did, I'd probably go the 12v car audio amp route and use car audio speakers.
