Ok, I see this mentioned everywhere I look when it coems to subs, can anyone enlighten an ignorant fool such as myself on what exactly this means and what's better? Now, I assume the higher is louder, but lower is better quality? what's a good db to have? etc. etc.

cheers.

I know SPL means Sound Pressure Level

and thats about the extent of my knowledge into that, from what ive heard the more spl u have or a SPL only sub it wont be as good quality as a SQ sub.

You are referring to the Spec SPL (db) I assume.

SPL = Sound pressure level
db = decibels. The db is shown as you can measure different types of SPL, for audio, we worry about db's though.

a decibel is a unit to show the intensity of a sound wave.

Now the spec SPL is another thielle small parameter (specs of speakers) this is the SPL when 1 watt is applied at a distance of 1 metre.

Ahh gotta fly more later...

Peace

Basically, deciBels is a ration between two powers. When a subwoofers level is stated in decibels, then it is comparing a current signal level to a previous level or preset standard level. A value given as decibels always has a reference, otherwise it is meaningless.

If you are talking about sound pressure levels (SPL), the reference is considered to be the lowest level that can be heard by human beings.

A one decibel change is considered to be the smallest change that can be percieved by the human ear.
