    Default Does one or two DB of Efficiency make a difference?

    Say 90 as opposed to 88 or 89.

    Also, what exactly is efficiency.. I assume it has something to do with how well it uses the power its recieving.

    Efficiency and sensitivity are sometimes used interchangebly by different manufacturers.

    "Sensitivity: Measure of the sound pressure level generated at a distance of one meter from a speaker when the speaker is fed a 2.83 volt signal (1 watt at 8 ohms); efficiency of a speaker creating a certain sound pressure level from a given input with high figures representing a more efficient speaker."


    Assuming the same measurement techniques for two different speakers, a 3dB increase in sensitivity will halve the power requirement to play at a paricular SPL. In other words, if my speakers are rated at 91, and yours are rated at 88, I will need half the power you'll need for the same SPL.

    It will make a difference in the volume the two speakers will produce given the same gear/power.
    HT: Denon 1910, LG blu-ray, Def Tech ProCinema 100s, Stryke 12" sonosub.
    LR: Onkyo TX-84 (original owner), Aiwa AD-F850 (original owner), Philips TT (old school, 2nd owner), Philips CD (cheap-o), Monitor 5jr+ (original owner - actually, my wife is the original owner; she bought them new when we were dating - sealed the deal).
    Xbox 360/Wii/Kids: Old school huge Sony HD TV, Sherwood RD-6500, Philips DVD, pair Def Tech ProCinema 100.

    Sweet, the R50s are sounding like a great bang for the buck deal.

    What that sounds like is called uncomfortable. Klipsch are way too sharp for my ears, screw that horn loaded thing, I need to hear.
