They are horn speakers, due to that they need proper amp matching as well as proper placement and room acoustics to sound good.

Not the same type of horn as the lab.


It uses bandpass loading below the speakers f3 (If I remember correctly) And proper power and placement are important for any speaker.

He compared his piezo array to a two hundred dollar ribbon array. Peizos sounded better. You'd need to eq's the speaker to the room anyways (smaart or some other RTA) so that not a big deal (ahem - don't your prized ev's and unity horns need that also?)




Bill F. making the bottom-feeders sound GOOD.
