speaker excursion..."mo power"..and bass..Sean


I'd be interested in everyone's thoughts, but hopefully Sean will chime in...

Some reading I've been doing & the "is 22 watts enough" discussion has raised a question in my mind. I'll use the Linkwitz Orions as the example, but the real questions will (should?) apply to powering most any driver.

I've been reading Linkwitz's site on the Orions, some of the theory, what it takes to build them, suggested power..etc...and I remember some post that I read in the A-gon or AA archives stating that the 60 watts Siegfred suggests isn't enough to give significant bass. I read on the SL site that he likes the 60 watts as the amp will clip just before the speaker can reach full excursion & thereby the driver will not sustain damage. He continues to state that the higher power amp he suggests (a larger ATI) will result in the driver reaching full excursion prior to the amp bottoming out & thus driver damage may result.

>Proponents of "lower is plenty" might be, at least conceptually, in line with the needed power to reach a driver's maximum excursion (almost by defintion) being all the power necessary.

>Then comes the "more power, preferrably gobs more clean power" crowd that says more power is the best in most applications.

So my question(s):

>Is the difference between these two camps just "time"(instantaneous versus continuous power)? i.e Lots of mostly unused power sitting "idle" as a reserve for the couple millisecond demand of those dynamic peaks?

>From what I've read the SL Orions do very, to exceptionally, well on bass even with the 60 watts. How would 200 watts instead of his 60 improve the bass if the drivers bottom out at a little over 60 watts? Is it again just the millisecond peak demand for power that would be available or is there another reason?

I do realize that this (very low power amps -high efficiency spkrs) normally sacrifices some of the very low bass
As you note, "normally". You can add active subwoofs for very little outlay and resolve the issue (if issue there is).
