I need to buy three of these drivers to complete my sound system and the only ones I can find are 16 ohm. I opened the spec sheet on it from JBL and it says they are 16 ohm also but when I open the spec sheet on the 4675A system, which is what I am building, it says the system is 8 ohms. So did JBL make 8 ohm versions too or are all of the 2445J drivers 16 ohm? Thanks for your help.

Both impedances are available. The horn has much more level than the woofer. If you are bi-amped, it may not matter much whether the horn is 8 or 16. Level setting before EQ will make them the same. If you are not bi-amped, then use less h.f. shelving on the crossover. Louis
