Thank you litefootdan, appreciate it! The component make up of the Venus is above in post #7. As far as sonics go, they fit well with my room, which is a fairly open floor plan. Typical soundstaging of an Omni, they stretch the room both sideways and also depth, yet not in any unrealistic way. They still portray what the recording gives, not more, not less. I think many people may not give Omni speakers a good chance, as most are so accustomed to front firing, typical box speakers. These certainly have a slightly different perspective, but one I call more like live music. They have a very layered appeal to them, the stage has a depth to it that again, is very life-like. Very decent and reasonable bass for a fairly smallish cabinet overall, in-room I have solid bass to right at 40 Hz, and still decent output lower.
These are fairly easy to site, but do pay rewards for getting positioning right. While one could pretty much plonk them down anywhere in the room within reason and get decent sound, like any speaker, it pays to give them the attention in order to get the best out of them. I drive these with amps that are good for about 90 plus watts/4 ohm load, which is what the impedance is stated for them. The crossover is a fairly simple one, phase correct(or about as phase correct as one can be), it is not a difficult speaker to drive, tubes, solid state, pick what you like.
I have had more Omni speakers in my lifetime than any other, Ohm, Larsen, Shahinian etc., and I tend to like what they sound like in my space. I cannot imagine selling these on, if only to maybe move up a notch on the Duevel lineup-but I better win the lotto for that one!
Hegeman's are interesting speakers, I have not heard them however. I also am intrigued by Morrisson Omni's too from Canada, also similar to the Hegeman and no doubt designed after it in ways. Good stuff there! If you want to know anymore, let me know, happy to discuss!
