PreSonus Sceptre S6 monitors continue this brand’s policy of delivering quality at a reasonable price. Because of that, they are by far some of the most capable monitors you can get for less than $1000.


In some ways, what PreSonus did with Sceptre S6 took some guts. Instead of going with the standard transducer configuration, they opted out for a more complicated and elusive coax setup. In other words, instead of having the tweeter sitting above a woofer, the two share the same axis. This way you have a speaker in a speaker which does a lot of sound imaging but complicates the design to a certain point.

Aside from this tiny detail, cabs feature a front firing wide port. PreSonus definitely wanted to focus the output as much as possible towards a single location. Cabs themselves feature a pretty solid construction and a fairly clean aesthetic design. Aside from those coax transducers, you would really be able to tell that this is a $1000 set of speakers. What is even more surprising is just how much performance they have managed to squeeze out of this monitor. More on that a bit later.


Let’s go over the features and raw specs for a moment. We have a 1″ high-frequency tweeter sitting in a coax 6.5″ midrange driver. These are powered using Class D bi-amplifier that is capable of delivering up to 180 Watts RMS. That is a pretty high value for a speaker such as this one.

Yet, it works great. On the back, we see balanced XLR and TRS inputs along with a fairly complex acoustic space controls. There’s an HF driver control that lets you attenuate the power as much as -4dB. Lastly, we see an HP filter that goes from 60Hz to 100Hz. Volume adjustment knob is also on the back panel, as expected.

As for the nature of the coax speaker, there is actually a DSP chip inside each cab that controls the behavior of both transducers. This tiny processor makes sure that the output is always optimal.


One thing you can expect from a coax monitor is a very tight response. That DSP unit really brings everything into focus, even if you are in a larger room. Even so, no one guarantees that the default sound you hear when you first turn the speakers on is going to match your room.

However, with a very little tweaking, you can bring that output right where you want it. By tweaking, we mean using the HF controls and other tone shaping features in the back of the speaker. One you setup everything to match your surroundings, the transparency you will get is going to be pretty impressive. When it comes to different genres of music being played through these monitors, the DSP chip will quickly adjust the transducers to match the signal being fed through the amp.

Overall, considering the type of money you are asked to drop on a set of these, it is fair to say that you get more than what you paid for.

The Rumble:

Even though they might be a bit more complex than your usual monitor, PreSonus Sceptre S6 are a very potent set of speakers. Those looking for ultimate transparency will come very close to their goal with these.
