In this segment, I have done an explanation of what the tech specs that dB Technologies have on their website for the Opera 15 speakers. I have covered the technical data that deals with the speaker type, acoustical data that deals with sound pressure level, frequency response, compression driver tweeters, asymmetrical horns etc. I have also covered the processing data which included RMS and peak, bit depth and sample rate. I have also covered amplifier the amplifier technology it uses. Below is an overview as summarized by dB Technologies.
