1.What does I.C.E stand for?
2.How many channels are in a Dolby 5.1 surround system?
3. How many ohms is the voice coil(s) in a JL13w7 subwoofer?
4. What is the correct name or terminology describing a free-air subwoofer?
5. A subwoofer produces 120dB of SPL, but the speaker is now required to produce twice this volume. What is the new figure in dB?
6. Two JL 12w7 subwoofers are joined together to end up with an overall impedence of 1.5 ohms. Are they linked via series or parallel connections?
7.Kenwood dual mag speakers are described as two way, but what does the term 2 way mean?
8.How many octaves are in the audible frequency range of 20Hz - 20kHz?
9.High pass and low pass are two different types of filter but what does an infrasonic or subsonic filter do?
10. What is the difference between an active crossover network and a passive crossover network?
11. In a 12volt system, how much current(amps) must an amplifier draw to produce 180watts if the amplfier is approximately 50% efficient?
12.What is the normal sampling rate of a CD in kilohertz?
13.If a sound wave travels 100 metres in 0.3003 seconds and a speaker in the drivers side door of a car is time aligned by -0.1ms, what is the speakers theoretical position in mm if the datum is the original speaker position in the door?
14.Take the answer to question (12) and multiply by the answer to question (11). Now take this answer and subtract the answer to question number (5). Take this answer and divide by the answer to question 8. Now divide this answer by the number of gigabytes music storage capability of the Kenwood music keg. What is the answer?
