can someone explain all this to me or some of thank you
Maximum SPL: >115 dB
Frequency response: 33 Hz — 20 kHz
Amplifier: Ultra-linear, high-capacity analog
Signal to noise ratio: >93.5 dB, typical 100
Input impedance: 8,000 ohms
Max. SPL: normally a rating for microphones for how much spl they can handle. in this case, it's probably just the loudest the speakers are capable of producing at a certain frequency. unfortunately it doesn't tell you what frequency this is at so it's kind of pointless.
Freq. response: this is what sound frequencies the speaker is capable of reproducing. humans can typically hear from 20hz to 20khz. 33hz -20khz is very wide range and is better than something with, say, 50hz-18khz.
Amplifier: basically, it's analog, not digital. so there is no Dolby decoding or anything like that.
S/N Ratio: generally, the higher the better. over 100db is preferred but above 90db can be considered "good enough"
Input impedance: should be 8ohms, not 8,000. it refers to the resistance of the speakers. amplifier outputs are rated at a x watts @ x ohms. make sure the speaker impedance matches up with the amp impedance.
