    I'm confused about some of the terms that I often read in the specs of speakers:
    - Freq: 35-20KHz at ± 3dB (what's the ± 3db for?)
    - Impedence: 8 ohm (why should I care about this?)
    - Lower Freq Extension: 30Hz (DIN) (what's that exactly? What does extension mean?)
    - Sensitivity-Room/Anechoic: 91dB/88dB (what's the difference between both numbers? What should I care for more?)
    - Suitable Amplifier Power Range: 15 - 350 watts (???)
    - Maximum Input Power: 210 watts (???)

    I would really appreciate your feedback guys.

    Go to this link: click
    If the link doesn't work, look for the HTF primer. It will answer all of these questions.

    Thanks, here are my remaining questions (the ones I couldn't find answers to):
    - Lower Freq Extension: 30Hz (DIN) (what's that exactly? What does extension mean?)
    - Sensitivity-Room/Anechoic: 91dB/88dB (what's the difference between both numbers? What should I care for more?)
    - Maximum Input Power: 210 watts (???)
    I would appreciate any answers or links [​IMG]

    I'll give this a shot.
    Simply put, if you supply your speakers with this much power from your amp, you will fry your speakers.

    I know Paradigm uses the "DIN" frequency extension number. According to them, that is the -3dB point in a 'typical' listening environment. Not quite sure what 'typical' is though...

    Thanks guys.

    - Suitable Amplifier Power Range: 15 - 350 watts (???)
    - Maximum Input Power: 210 watts (???)

    If max input power means I should supply more power than 210, then why can the suitable amplifier power range reach 350 watts!? I'm confused again. Are those numbers above not about the same thing?

    Kurt,

    The 350 Watt is a "Program" or "Peak" figure. It means that
    the drivers could safely take 350 watts for about a second
    before they would fry.. 210 watts is that absolute amount
    of continious power they will take before damage occours to
    the speakers.
