ZU OMEN speakers 12ohms??

Use the tube amp with the 8 ohm tap. Should be fine.

Cwazz,

Check out the thread in the cheap and cheerful section of Audiocircle.com A number of ACers have purchased the Omens and posted thoughts and impressions there.

I have them and they are fine speakers, good budget components that allow you to experiment with many amps. I use them on the 8ohm tap as that is all my amp has. Depending on your room size you only need a couple watts. My amp has 9w and I never have to turn it up beyond 11 o'clock.

I realize my experience is with the Essences so it might not apply exactly to the Omen. However, the both share the same 10 inch wideband driver. Compared to the 4 ohm tap, the 8 ohm tap delivers a crisper, faster, more open presentation. Until my speakers settled in a bit, I felt it was a bit too "in your face." So I tried the 4 ohm tap and found it smoothed things out a bit. The down side was the 4 ohm tap made things a bit too polite. Not offensive in any way and some listeners might prefer it over the 8. I thought the highs were rolled off a bit and the overall presentation lacked some air. A good demo would be Black Prarie's "Red Rocking Chair." In the end I think it's a very subjective call. Use the tap that produces the results you like the most.

Incorrect.

Essence and Omen use different 10" drivers.
