Aesthetix Calypso Signature to Eclipse

(((My subs are powered, and I've read that it's better to run them via line out and not through speaker level.)))
 
 Have you tried your subs via speaker level?
  I think you may be in for a pleasant surprise.

No, but I don't always run my subs.  They stay connected but are often off.

Audioconnection:

Are you suggesting run the sub at speaker level instead of pre-amp split?

what damage will it cause to Calypso?

Thank you!
