Convert Your Sierra-1 To Sierra-2EX

DIY upgrade kit to convert your Sierra-1 speakers to Sierra-2EX.

This is a huge performance upgrade while also being a fun and educational project.

Sierra-2EX is a significantly better speaker than our Sierra-1 and rather than purchasing a new pair of Sierra-2EX, upgrading is easier on your wallet.

Your Sierra-1 speakers will now become full-fledged Sierra-2EX!

Detailed instructions are included. If you prefer not to do the work yourself, we would be happy to perform the upgrade for you. Simply give us a call or send an email for details. There are advantages to having us do the work for you. 

*Note: 1 kit needed for each speaker.  A pair of speakers requires 2 kits.
