First impressions at California audio Show

[Sir Terrence the Terrible]

I heard the JBL Everests. They can put out more volume than the human ear can take, and the bass will shake the room. You need a HUGE room for these speakers. Driven by thousand watt ss amps, the sound was hard, and unlistenable to me. The smaller JBL speakers sounded smoother.

Tube fan, I told you that you spoke to soon. We do agree on something!

One person said "They lack finesse, sibilants are emphasised, the high notes can be too sharp, the tempo is too fast and the images are much larger than life.But they can give you the sonic equivalent of a roller-coaster ride - the thrills and spills and sonic booms that only a pair of big, loud and fast speakers can create."

This about sums it up perfectly.

The Teresonic speaker, one driver, a Lowther DX4 unit, has, of course, no crossover and is extremely efficient. The sound on several of my vinyl records was extremely close to what I hear from my main system, but they would not turn up the volume, so they probably would sound even better played at realistic levels (to me, this means something close to the level you would hear live).

They wouldn't turn up the sound because those speakers don't do loud that well - it cannot hold its composure. They also have issues when the mix is complex, dynamic, and touches on the frequency extreme's

When they played High Altitude Drums through it, it sounded good on the horn prelude at the beginning. But when the horns ALL came in along with the percussion, this speaker turned a very good but complex mix into a sonic mush that had zero definition. It is much like using you kitchen's drain to empty a large lake. It is very difficult to design a single driver that covers 10 octaves without giving up the ghost somewhere.
