    D123, 2400 crossover an 075 tweeter

    Hi people, I was being offered a set of woofers D123, XO N2400 with tweeters 075 in some enclosures unoriginal, I have been looking for the sensitivity of these woofers and I have not found are 16 ohms and I thought attaching to a Single Ended Triode 45 amp with 4 / 8 ohm, unfortunately I do not have 16 ohms in the amplifier, some problem with the impedance, I appreciate your comments and suggestions on these old JBL, thanks, Martin

    The D123's are all 8 ohm whether they are labeled 8 or 16 ohms. If it were truly 16 ohms it would still be ok to hook it up to the 8 ohm tap. Sensitivity of the D123 by the old EIA methods was 49, which I think translates to about 98 by today's method. The sensitivity of the system with crossover would probably be about 3 dB less.
