Presence Upgrade Kit Sans Amps

3,500.00

This is a full-out rebuild of this classic Zu speaker. It's not cheap but it will totally transform them. This kit does not include new amplification for the bass section, for that you need to also purchase the Presence Amp Upgrade Kit.

There are two stages of upgrades available for the Presence. This everything but the amps kit requires some woodworking skill—if you are not comfortable with a keyhole saw, electric hand drill and wood rasp please don’t purchase the upgrade and attempt to do this yourself. Instead, purchase the kit, get your speakers back to Zu and have us do it for you, factory service is $600 for the pair.
