As another option for an owner of pre-PX U-1, M-1 or A-1 Sound Lab speakers who wants or needs to replace their older panels and up grade to PX (45 degree) panels, I would offer the same 90 day warranty. Pre PX panels were subject to problems that required return to the factory for membrane replacement. Since the introduction of the PX technology, this has become a rare event. Thus these PX panels will likely provide years of trouble free listening.
This offer would not include the Ultimate frames nor backplates, panels only. $4,500. Shipping negotiable. If you would like to discuss this possibility, please send an email with your phone number.
Thanks,
Tom
