Zu Omen or Tekton Lore

Speaking with Zu experience. The main driver runs full range without a crossover, covering 30hz-12khz. The supertweeter then has a capacitor and resistor inline from the main driver ensuring it fills in the highs from 12-20khz.

Not a traditional 2 way design but maybe 1.5way!

Zu had a list of amps they tested the Omen with. Best bang for buck accordinig to Zu was the Dynaco which fits your budget. There were quite a few others some of which have been mentioned.

Don't let the price of the Eminence drivers worry you. Being one of the largest driver manufacturers in the world and the b102 a classic means they make 1000s of them for Marshall and Fender and other pro audio oems etc...... Economy of scale

The idecco was used by Zu to demo the Omens so the Lores will be fine, don't forget the Zu Souls on special for $999 in the mix.

These speakers are 97+db sensitive and a really easy load as they don't drop below 6 ohms. 40w drive them to sound levels that a "normal" 91db speaker with 200w can achieve.

You'd be surprised with high efficient designs...... It's the quality of the first watt that matters as 90% of your listening will only require 1-2w
