Everest Question
This is not a criticism but I am just wondering how a speaker this expensive, this large, weighing 142 pounds and having two 15" bass drivers can only go to 45 hz???
Any thoughts??? Thanks.

Horn loaded-Needs a huge cabinet with more volume in order to go lower...?

In looking at the product info on the JBL site, I would guess that the answer has to do with the cabinet volume. The system is a bass reflex design,and although they are quite large, I suspect the cabinet volume/driver size compromise was picked to give significant output at very low distortion levels, while counting on room gain to get the bass to the 30hz range in room. 32hz is listed at -10db, and corner or near corner placement could easily get that up to being flat. A real, undistorted 30-35 hz can be a beautiful thing.
FWIW, every review I've seen says that they are phenomenal speakers and not one has said they were bass shy.

That's because a speaker that has smooth bass response, even if it doesn't reach all the way down will always sound natural and musical and the lowest octave will hardly be missed. On the other hand, a speaker that introduces bloated, lumpy bass will stick out like a sore thumb and usually annoy the listener. Nothing drives me more crazy than having bloated bass and overhang in the room/system.

I am not familiar with what JBL is trying to accomplish, I only speak from my own personal experience and having observed the reactions of others over the years with my own as well as their systems and everyone so far has agreed that having to choose between quality and quantity when it comes to bass, quality prevails. Of course once that deep but well controlled bass is experienced, it is hard to part with.

Thanks for all of the great info guys...
I finally understand why some of my favorite speakers don't "measure" to go very low.... I'm a slow learner for sure... |
