I'd like to share with you some audio math. No this isn't about spread sheets, or room analyzing. This is an easy to follow formula that anyone can use to improve the sound.
Guys looking to buy may want to read this cause it could change the way you look at your purchase. Guys looking at their system wondering why, may also find use with this.
Lets start with your fuse box or circuit panel. Go to your panel and open up the door. What your looking at is the beginning of your system. You've heard people say dedicated line? Tell me on this panel where the dedicated line is? Looks to me like all the connections go to the same source. Truth is there is no such thing as a dedicated line unless you have a separate box with separate meter. Fact is each load in your house is part of your audio system. Don't believe me, turn off and have your electrician come over and unhook all the wires except the one or ones heading to your system, we did. The difference to the sound is one of the biggest eye openers you will have heard in years. Slowly put back in each wire on the panel, and you will hear how much even the wire without any current will affect the sound. I would say shocking but that would be in poor taste. The safer way is to trust that we did this for you. The way your panel is mounted, the way your fuses are plugged in, where your wires are at, the wire size and makeup, the route they take through your house, all have a great affect on your sound. If your wire is too insulated or out of balance size wise with the rest of your system you are going to loose some audio signal. In audio, bigger is not better, balance is. The closer you can get to using the same guage throughout your system the better the sound will be. Not saying you will be able to do this, but I use 22 guage throughout my setup or as close to as I can. If your electrician can balance the wires going into the panel so that the wires are spaced more evenly and without tention on them your sound will open up.
still on the electrical
Notice how much the sound improved? Now lets take a look at the system from a math point of view. In audio we have all kinds of shapes and sizes, but without you getting all tied up let me share a couple of thoughts with you. There is one part in every audio system that provides a necessity, but also generates fields that can distort the signal greatly, the transformer. The fewer of these power plants you have in your system the cleaner the signal will be. Add this with me. Circuit panel outputs, wall outlets, appliances, audio system power cords, multiplug extentions, line conditioning. All of these add up to noise.
Let's say you have an audio system that has two sources, a phono pre, preamp, mono blocks and sub amp. That's 7 transformers. We're not done Line conditioning and or power strip or strips, wall outlets. Just from a math point of view lets put this up against a two component system, source and amp. No conditioning or strips and only one outlet. The bigger system has 5 times more electrical/mechanical/magnetic interference going on.
now lets add the speakers and crossovers
Lets say on a two way simple system the drivers and cabinet were well matched and you used only a cap and resistor per. This gives you 4 motors (the magnets). On your more complicated system, you have your sub or subs, maybe panel speakers or maybe a 4 way. Lets go with the 4 way. Two coils per speaker and 4 magnets per. In this case (if using two subs) your using again 5 times the amount of interference.
This is just the electrical.
