Open Baffle Convert

How far out in the room are you all placing them? The conventional wisdom that OBs require a ton of breathing room has always seemed to me a serious objection, for many of our rooms.

Have you guys heard of the DIY OB/Dipole sub from GR Research/Rythmik? Very special!

Open baffle has rear output which allows the speaker to take advantage of the ear/brain system's abilities to find the source of the sound- in effect, the reflected sound improves the soundstage.

They can make bass too if properly set up. However it does seem that you get the best results if the output impedance of the amplifier is higher rather than lower! A tube amp that does not use negative feedback is recommended- this will put the output impedance in the right range and it will be easier for the speaker to make bass.

I have them about 32" from rear wall. I have used both a small tube amp 3.5 watts per, and a t amp of 15 watts. The drivers are 97db so power is never an issue. I would think putting them too far from the wall would make them less effective. the front baffle is 24" wide

Open baffle speakers load the room differently than a enclosed box. Bass increases rather than decreases as the speaker is moved away from the front wall.
