Well my system is complete! I will post pictures later in the pictures of computer rig forum and will post before and after shots. My brother got my old system. The subwoofer was the biggest difference. The bass is so much deeper and overall the sound is thicker and clearer. Everyday I am enjoying it more. On to the Airmotiv 5S. Without the subwoofer they offer lower bass and a more complete sound. Right now I have the physical EQ at +2 for tweeter and -4 for bass. On their own they are an upgrade from the M-Audio especially if you do not use an EQ DSP. Currently I have no DSP's with the monitors and the subwoofer is working perfectly as the crossover. No humming whatsoever which I was dealing with through the subwoofer cable. They do not sound that much different. In the listening position I notice mainly more impact, a little bit more fullness but in terms of clarity my M-Audio hold up. Listening in bed, the sound is more intact. If you want speakers to fill a room, I feel like these are less nearfield than the M-Audio's which is great. Of course they have much more power, too much for my little room.
Overall, was it worth all the money? The sub I feel is great for the deal I got on it. The crossover works well and the bass is thick and deep. Now I can run any DAC I please which will be my last sidegrade as I want something external. The Airmotivs maybe are 10% better without the sub and maybe 5% better with. My original setup I would say is 85-90% of what I have now and mainly because of the bass. In a larger room it would be much different. The sub would pull ahead much further and the Airmotiv would fill up a room better. Granted this is the first day, everything is new, sub, speakers, cables, calibration. I felt like my previous was too good to be true considering how cheap it was. Now after spending the money you feel that you really do not have to spend the money, at least not right away. And match the output to the room. My system is way too powerful but still functions great. I will say the sub and speakers are gorgeous, they might not sound that much better but they look better and that is what audiophiles care about right?
Overall, again, I would say I learned a lot. If you are doing 2.1 system in a medium too small room for pleasurable listening than get the sub $250 monitors from M-Audio, JBL, KRK, whoever you like most when auditioning or whatever deal comes up. GET A SUBWOOFER! That is all I can say. Even a cheap Yamaha like mine will make the sound twice as good. But for $265 that I paid for my Presonus it is a beast and now they have an 8 inch model which would suit smaller rooms better. I am not regretful. Expected a little more but over time I will keep adjusting and getting used to the sound. I am pleased. You pay a lot of money to get a little better performance. I would upgrade my room before anything else. Might make another thread with this message.
