15 subwoofers would produce 15 times as much power. log1015 = 1.176; to convert that to decibels, you have to multiply it by 10, so you get an increase of 11.76 decibels, in other words, 180 + 11.76 = 191.76 decibels. Since the 180 decibels probably includes some rounding, it makes sense to round the final result, too - for example, to 192 decibels.
As with many verbs in the English language, the preposition afterwards can make all the difference. 'Pick up' and 'pick out' have different meanings, 'take', 'take off' and 'take out' (etc!) too. These are called Phrasal Verbs. So, both 'wonder' and 'wonder about' are correct: the first means 'marvel, be amazed by' and the second means 'ponder', 'consider (usually inwardly)', so there is also the possibility of 'wondering out loud about' something.
.56 * * * * * The above answer is total rubbish! The correct answer is 15. A decimal is a way of representing a number in such a way that the place value of each digit is ten times that of the digit to its right. A decimal representation does not require a decimal point. Adding zeros after the decimal point is wrong because they imply a degree of accuracy (significant figures) for which there is no justification.
In probability theory, the birthday problem, or birthday paradox[1] pertains to the probability that in a set of randomly chosen people some pair of them will have the same birthday. In a group of 10 randomly chosen people, there is an 11.7% chance. In a group of at least 23 randomly chosen people, there is more than 50% probability that some pair of them will both have been born on the same day. For 57 or more people, the probability is more than 99%, and it reaches 100% when the number of people reaches 367 (there are a maximum of 366 possible birthdays). The mathematics behind this problem leads to a well-known cryptographic attack called the birthday attack. See Wikipedia for more: http://en.wikipedia.org/wiki/Birthday_paradox
A 2 x 4 is piece of lumber typically used in framing houses. A 2 x 4 actually measures 1-1/2" x 3-1/2" - as the wood dries it shrinks until it reaches this nominal size. Typically lengths for 2x4s are 8' and 12'. This lumber is typically made from a soft wood, like pine. When used as the verticals of framed walls, they are called "studs".

Most subwoofers have their own power source. There are subwoofers called "passive" woofers that will be powered by your amplifier.

Just like any other substance in existence, the magnitude of sound or loudness can also be measured. In this case, the standard unit of measurement for loudness is called decibels.
The degeneration of a signal over a distance on a network cable is called attenuation. It does not have any relation with decibels. The strength of signal just gets reduced.
