Woofer upgrades to Audio Physic Libra's


Has anyone performed any such upgrades? The original (4) woofers are 8"; I think they may have been made by ScanSpeak.

Any suggestions?

Which upgrade are you considering, just curious. Do you more bass, you might want to upgrade the crossover.
I had one woofer fail, so am taking the opportunity to review possible upgrades. Overall I'm very happy with the speakers, but a bit more punch in the lower end would be a nice improvement. Do you have specific thoughts re the crossover?
Hello- just checking what you've done regarding failed woofer?
Did you replace one or All for for them to match?
