I have a couple of questions about H-Frames.
1) If one was to physically align woofers facing front and back, what would be the ideal vertical alignment plane on the woofers (e.g. bottom of cone, half the depth of the cone, half the volume of the cone, outer edge of the cone, or something else) ?
2) Instead of stacking multiple drivers immediately on top of each other, would it be acoustically beneficial to vertically space them out into more of a taller line array of a triple or a quad to match the height of your main line arrays (or would this be more dependent) ?
3) Where are the prices listed on the HX800 amps ?
