What stands would you recommend for the HD4's?

If looking for a desktop stand, our DS2 desktop stands are sized to fit the HD4's almost perfectly. You can also use the Sanus Steel Series Speaker Stands, however the HD4's do not have threaded inserts in the bottom of the speaker.

Lastly, here is a list of stands our customers have recommended for wall mounts:

Vogels VLB200 Speaker Wall Mount
Sanus WMS2 Speaker Wall Mount
BTECH BT-77 Side Clamping Wall Mount

We tend to recommend clamping mounts as they allow for a quicker and easier setup.
