Carvin amp serial number lookup11/12/2022 ![]() ![]() If the speaker is need for rated power usage, the program rating is a good target to use to determining the needed amplifier power for the speaker. The program rating is an in between value of 3 DB over the continuous rating suggesting a nominal power with heavy music. I say most, because there are some higher peaks. The peak rating is 6 DB higher than the continuous rating where most of the peaks generated in the pink noise reach. The continuous rating is the RMS value of the pink noise. In many cases this is around 30-40Hz for mains speakers. A speaker is tested using pink noise limited to (or crossed over at) the lowest frequency the cabinet was designed to work. THE WHAT: OK, now to the root of continuous, program and peak speaker ratings. If the system is not large enough for the performance and the amplifiers are clipping, it will damage the speaker even though the wattage of the speaker is rated higher than the amplifier.Īlso, sine wave bench test signals, used to measure the RMS power of an amplifier, are too constant and can heat a speaker voice coil up prematurely not representing a speakers 'real world' rated output. ![]() You can't under power a speaker and damage it, but you can under power a performance or show. This is were the 'under powering a speaker' myth has been so twisted in it's understanding. This is because the small wire inside the speaker making up the voice coil is only capable of clean non-clipped power levels. THE WHY: Speakers are rated differently than power amplifiers. There's little excuse for not being able to search on serial numbers. ![]() If it's rounded, but has an acoustic/electric type of pre-amp on the. ![]()
