Will high SPL subwoofers damage planar speakers?

Hello!

I am looking at upgrading my mains to something in the realm of the Quad 989s or the like. I am worried that placing them in front of my Audiophysic Luna subwoofers may cause damage to the panels by forcing them to move from SPLs in the 100-110db range. Has anyone experienced this problem, or can set my mind at ease about possibly damaging the panels in an electrostatic speaker given this configuration?

Thanks!

Quad 989 speakers will be damaged with high volume levels and they are very expensive to repair. If you listen at high volume this is not the speaker for you.

If you like playing loud no electrostatic can really play that loud without distorting, especially Quads, you should find good dynamic loudspeakers that are transparent, KEF, Vivid, Wilson, etc.

Audiooracle, Wrong. Innersounds and Sanders Sound can play that loud without distorting as long as the amp is up to the challenge. Martin Logan Summit's can play pretty loud as well but since I don't own them I'm not sure exactly how loud.

Quad's on the other hand will go into protection mode if played over about 95db. The sub would go louder though. I'm not sure how loud stacked Quads would go. Probably 3 to 6 db louder?

As far as the sub damaging the panels I doubt it. Many people have had Quads paired with subs before. Hopefully they can chime in.

"Quad's on the other hand will go into protection mode if played over about 95db."

The protection circuit is not saving Quads from damage.
