Hi everyone
I have several doubts regarding subwoofer and its amplifier
-1- What is the basic difference(in construction,working and performance) between a subwoofer and an ordinary woofer ?
-2- When was sub woofer first introduced ?(And who introduced it ?)
-3- How can I detect a distorted output from a subwoofer ?
-4- What are the specifications of the box on which the sub is to be mounted ?
-5- Is the shape of the box significant ? Or is that the volume of the box that matter ?
-6- I have bought a subwoofer named 'DAINTY'.On the sub the following are written...8 Ohm,130W RMS,260W MAX .Have you ever heard a company like that ? Or is it a local make ?
-7- Will an amplifier constructed with a TDA 7294 work ?
-8-What should be the power rating (I expect VA,RMS output voltage,RMS output current) of the transformer to be used for maximum power output ?
-8- What are the rating of the rectifier diodes and the filter capacitor to be used for the dual DC power supply ?
Thanks in advance
