    2215H Sensitivity 1W@1m?

    I can not find a spec sheet for this driver. The older 2215A/B sheet lists sensitivity at approx "45dB spl at 30 feet with one mW input warbled 100 to 500Hz"
    Thanks in advance for your help in interpreting....

    Select 15", JBL, discontinued, visually scan for 2215H,
    find sensitivity 96dB/1m

    Hope there aren't any mistakes

    Maybe compare K or E145 series.

    94.2 dB

    Calculation is:

    45 dB + 10*log(1000mW/1W) = 75 dB at 1 watt @ 30 ft

    20*log(3.28 ft / 30 ft) = -19.2 dB decrease @ 1 meter

    75 dB - (-19.2 dB) = 94.2 dB at 1 watt at 1 meter
