DIY open baffle speakers featuring the Hawthorne Sterling Silver Iris 15" coaxial driver, Hawthorne 15" Augies for bass augmentation.

Augies are powered by 2 x 500W BASH amplifiers by O-Audio, these are mounting in matching oak-trimmed boxes which can be placed behind the Augies, or separately.

Baffles are a super-solid 3 inches thick (3 layers of 3/4" baltic birch plywood + oak trim).  Each speaker measures approx 43" tall 23" wide x 20" deep

Crossovers are wired point-to-point, with decent components (massive Jantzen Wax Coil Copper foil inductors, Obbligato Gold caps, etc).

Bases contain the crossovers, are sand filled, and have spikes for leveling.

Grills included.

I'm the 2nd owner.  Time to move these on to someone who will make use of them.

$650.   Available for local pickup in Boulder, CO.   Willing to deliver within 100 miles of Boulder.  May be willing to meet halfway for farther distance.
