Again, in cases someone is reading this thread for the first time.
There is plenty of experienced and happy customers with Big-E. Nothing wrong with that.
Asking for measurements is in no way disagreeing with personal experience or opinion.
Personal Experience, Opinion, are not a dichotomy. They often go hand in hand in the real world. This is what improves products over time. Take what's available, measure it, improve it, measure the improvement, ...
In most cases the measurement usually match up to actual listening experiences. I can't think of any cases where this hasn't been true.
Science gets something wrong once in a while, but it is a process, self correcting, and gets it right more often than wrong.
If there is a new technology for Big-E it would be interesting to see what the measurements say about these compared to other reference speakers.
PA use of Big-E cabinets is often mentioned even in this thread. And in PA/FOH field it is more common than not that measurements are taken and made available. But of course a soundperson is no good if it doesn't sound good. There has to be a listening aspect to it. A sanity test.
