Loudness equalization will (in most cases) decrease your volume, which is not needed. Disable all enhancements! If you have headphones, use the designated headphone jack that is connected to the front panel headers on your motherboard, as headphones (both in drivers, and in windows) usually allow for more volume. This is because there is less power required for headphones compared to speakers. If you have a multi-speaker capable motherboard/sound card, you will have lower volumes without an amp because your mobo/sound card is dividing the current between the multiple outputs. There is really no way in windows to do anything. If your motherboard/sound card has the ability to change power settings, you may be able to get away with pumping more current (amps) through your connections. I have not seen anything like this, nor have I ever had a high end sound card. I have always just used an external amp, or the headphone options. As stated in an earlier post on this forum, it definitely depends on your motherboard, as different motherboards have different standards for power, in terms of how much current can be put through a terminal.
Simple tips that may help others when looking into audio/electronics.
-Amps (short for amperes) = current measurement, proper terminology: amps go THROUGH a leg, branch, connection, etc.
-Volts = electric potential difference. Voltage is tricky for many so pay attention. Voltage is the potential energy, it is the energy required to move current. It is in essence, like pressure in a water line. Since this is not a physical/atomic being like current, it doesn't go through anything, it goes ACROSS, or OVER a leg, branch, connection, wire, etc.
-Watts = power, the rate in which work is done. The more work needed to be done requires more watts/power. When your speakers are vibrating, the larger the speaker, the more power needed. The more bass, the more a speaker needs to flex, and the faster it needs to flex. This all requires more power (faster work). The proper terminology is watts is as is basically. You will normally see watts when power requirements or consumption is being discussed. So, another example would be, the more powerful components you have in your PC (that top of the line processor, that massive video card, etc), the more wattage is needed. That is why you get a higher wattage rating power supply.
--Last but not least Ohms = resistance. Think of speakers as a water faucet, the lower the resistance, the more current that can get through. If you have a high performance sub-woofer, you will have a lower resistance, as the woofer will need that current and power to produce that big low bass sound, and it will also need it more or less for those thuds, (which if you have researched enough, you will find for those short spurts of bass, or "thuds" as I call them, smaller/mid-size sub-woofers are better than larger ones).
-That is all you really need to know, there are other values such as Siemens (conductivity measurement), and Coulombs (electric charge measurement). While those are important, they are not commonly spoken about, nor that important for audio device consumers.
--Hope this helps!
