ESX Quantum Q120.4 Amplifier - $365 shipped
Times are getting rough so I have to reluctantly sell one of my prized amplifiers. The 120.4 is a super rare Zed made amplifier that has a multitude of crossover and power options. It is the only amplifier/processor you need to run a 2-way active system. It's not very pretty but works 100%. I will include the manual because you WILL need it. Click on the thumbnails to see the larger pictures. Email (daddyoppe(at)aol(dot)com) or PM me if you have any question or would like additional pictures. THANKS!

Output Power at 12V:
• 4 x 120W @ 4 ohms
• 4 x 180W @ 2 ohms
• 2 x 240W @ 8 ohms bridged
• 2 x 360W @ 4 ohms bridged
• 2 x 150W @ 4 ohms bridged "TRUE MONO"
• 2 x 240W @ 2 ohms bridged "TRUE MONO"
• 2 x 360W @ 1 ohm bridged "TRUE MONO"
• 2 x 250W @ 4 ohms bridged "TRUE MONO / HIGH VOLTAGE"
• 2 x 400W @ 2 ohms bridged "TRUE MONO / HIGH VOLTAGE"
• 1 x 300W @ 8 ohms "MONOBLOCK"
• 1 x 500W @ 4 ohms "MONOBLOCK"
• 1 x 720W @ 2 ohms "MONOBLOCK"
• 1 x 500W @ 8 ohms "MONOBLOCK / HIGH VOLTAGE"
• 1 x 800W @ 4 ohms "MONOBLOCK / HIGH VOLTAGE"

The only trade I'm looking for is a clean Q175.2 + cash.

No visible chips or bent fins when mounted. I guess a clean Q175.2 would be about $225 so ~$140 cash.

The Q120.4 is in fairly good physical shape. It has some paint chips but there are no bent fins and the bottom plate is straight. A powder coat and a new silk screen would make it perfect.

Yeah, I think the price is reasonable. I have another Q120.4 that I will never sell.

Seriously, if I wasn't unemployed and had not gotten a very expensive speeding ticket I wouldn't be selling it.
