Just as an FYI, this is what I use to push 2 Yamaha speakers (connected in parallel to 2 JBL higher frequency range speakers).



That Peavey mixer is from like 1996 and was something like $150. 6 mic ins and 4 stereo channels that can also be used as 8 mono channels by panning L&R. Effects loop, tape in and out. Tracked down the last set of rack ears on the planet (that mixer is LONG out of production) from a warehouse in Mississippi for $30. (6 spaces)

That EQ I bought used for $40 on Guitar Center's used gear web page. (2 spaces)

The Alesis reverb I bought for $25 on Craigslist. (1 space)

The power amp is 450 per side (3 spaces), and it's an amazing story. I posted on Facebook that my power amp took a dump. Within TEN MINUTES there was a text message from a friend who said he had one he'd give me. I drove up to his house to pick it up, brought it home, took the cover off, blew the junk out, sprayed the pots with tuner cleaner, and it is in it's new home at the bottom of the band's practice PA rack. I gave him 2 tickets for him and his wife to attend our reunion show and we called it even.

The rack is a 12 space tabletop rack that costs $30 new from some company in that state up north. (Ohio State fans can't bring ourselves to name that state up north.)

So, to recap.

$150 for a mixer (and you can do better for used gear).
$30 for the rack ears (you may not even care to mount it).
$40 for a stereo 31 band EQ.
$25 for a digital reverb (and I have 4 of that model, all eBay or Craigslist finds).
$50 for 2 tickets in trade for a strong power amp.
$30 for a rack.

$325 for that whole rig.
