Home Audio DIY heaven

Linkwitz Lab is home to the Orion, Phoenix, and Pluto speaker systems.
These are not sets of speakers that you will find in Best Buy or
Circuit City, nor even your local high-end home audio store. The
speaker systems designed by Linkwitz Lab are primarily DIY, but they do
allow ordering of partial and fully completed sets. There are many
reviews on the Orions in particular that compare them to some very
expensive high-end audio systems, and yet they can be purchased at a
fraction of the cost.
