JBL E155 PDF

Antarctica One more thought: the benefits of not shoving a coil in front of a woofer driver are significant, especially in this case were the nominal impedance of the E is 4-ohms. A typical big-ass air core 1. However, there is always a good argument for using crossovers or higher slope crossovers. We get the drivers working in their prime spots and we push their bad behavior down in amplitude. The cost, as explained above, is more "crap" in the way. More power robbing coils and to a lesser extent caps.

More power robbing coils and to a lesser extent caps. One problem of course is that it is difficult or impossible to measure subjectively observed dynamics. We need steep crossovers. This is really the realm of active networks, amps for each driver, maybe DSP, and wholly another topic.

Here are some photos of the JBL The JBL is a 4-way speaker from the 70s: 18" woofer, 10" low-midrange, midrange-high horn with fancy lens , and slot supertweeter. More crossover parts, but the approach is still minimalist. The polar response is better too. Overall efficiency is less than the b, but we can argue that the cheats via the use of a 4-ohm woofer.

Some of the drivers are unobtainable now. However, it might be a neat idea to do a modern interpretation. Maybe I should quit my job and see if Schiit would be willing go in on it to keep parts cost down.
