The F5 studio monitor is the model that started it all for Fluid Audio. While it is often referred to as a "budget" monitor, the F5 brings a lot of technology and value to the table. The amplifier has a generous heat sink for long mixing sessions. Most monitors have their amp heat sinks inside the cabinet where all the heat is generated and cannot escape. The F5 amplifier ICs are mounted directly to the heat sink, so heat can transmit harmlessly away from the drivers and internal circuitry. The amp also has something no other monitor in it's class can boast - A standby circuit that shuts down the amp after 20 mins of non use. This is our small contribution. The well reinforced MDF cabinet minimizes resonances, and the front mounted bass-reflex port allows the bass energy to radiate directly towards the listener. And unlike many other monitors in it's class, there is a volume control on the front baffle for easy access. All of these features come together to create a great sounding yet transparent listening and mixing experienceat a great price.
