The arrays on the left do no maintain a near field completely across the frequency band but have exceptional sound quality. They were named best of show at the Atlanta Southeastern DIY speaker show last fall. The small 'woofers' are Tang Band W3-871S drivers while the ribbon is the Aurum Cantus G3. They need a subwoofer below 120 Hz as you can only get so much from 3" diameter drivers. Total cost for the parts kit and plans is $1000 from

The arrays on the right are the Linus 2 from

who offer both parts and plans in a kit. This array is a true near field array across the band. The drivers are Vifa TC14's which is a 5.5" mid-bass and the Silver Flute YAG20-1 (from Madisound).
