In answer to the questions in this thread about my DNA Sequence speakers:
1. The midrange/treble section is 95dB/2.83V/1m sensitivity with 8 ohm impedance. The dipole woofer, of course, is much lower sensitivity.
2. The midranges used in the DNA Sequence are not the same model or size as mentioned in the patent text.
3. Regarding their retail price, I wouldn't say they are horribly expensive. I'm a small manufacturer (my full time job is Engineering Director at AuraSound), and limited production specialty items, such as these speakers, are very costly to produce. For example the cabinetry is made here in California (not outsourced to China) by the same hands who made the legendary Infinity IRS V cabinets. Also, I know no other commercial speaker at similar price which uses a woofer as costly as the AuraSound 15" (which I designed a custom version for my speaker). And then there is the active crossover, which is quite unique and topic for a separate discussion.
