helo, first off I wasnt referring to your setup, or bashing it at all. I like it, very much. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I just would recommend a combination slightly differently for someone starting out new. I agree with your linearity comments, except when you DO factor in Xbl^2. Look at their BL curve, its flat. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif For example, an Adire Koda would be a better fit for that power range, and would reach its limit easier. But with its Xbl^2 motor design, its distortion output, even near or at peak excursion is basically inaudible... that's the beauty of Xbl^2. Headroom is a proven SQ technique, but Xbl^2 really limits the need for it. factor in a tight budget for the sub, and Id recommend a smaller (Xbl^2) driver.
But again, I do agree with what you are saying on linear excursion with non-BL optimized drivers, 100%.
BTW, did I mention I really like your setup? //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Ive always thought those Orion amps are the best looking amps made, and well, XXX's are simply audio-bliss. Which is why I bought XXX's, and may consider Orion amps to push them.
