Will high SPL subwoofers damage planar speakers?

sorry I beg to differ no electrostatic goes as loud as a dynamic speaker, the issue is the amount of air displacement and throw that the diaphram can move before it hits the stators.

The innersound are okay speakers at best, I have heard them on several instances didn't blow me away at the least.

At shows I heard a set of Vivid rattle out the lighting cans out of the ceiling, never heard an electrostat that could move enough air without getting hard at loud levels and compressing.

There is no perfect speaker. Some speakers excel at rattling light cans from the ceiling and other speakers excel at nuance and truth of timbre. They all have their place and everyone has different taste.

Agree 100% w Rrog's comments. My 989s went into protection mode everytime I play orchestral pieces with cymbals eg. Rach II 3rd mvt. Whether your run a crossover to move the bass to a sub is irrelevant. Want to play loud? get Wilsons.

Audiooracle, you hear something at a show so that makes you an expert on it? Wow you must be good!

I never realized that an electrostatic speaker had such limited dynamic range! I do listen to music quite loud on occasion, especially orchestral and electronic music. I have measured SPL at 100-105db at one foot from my speakers on many occasions, even upwards of 110db a few times...so I take it the consensus is that electostats are not for me?!

Thanks for your input!
