I just picked up a pair of Infinity Prelude MTS and I was wondering if anyone has any experience with the RABOS system.
Thanks

Also, unless specific calibration curves have been provided for the Infinity SPL meter, it must be considered as accurate (or inaccurate) as the RS meter - IMO of course.
Does Radio Shack provide a calibration curve? I did not see one with mine. If you read Dick Pierce's writing on rec.audio.high-end he claims to have measured dozens of RS meters and they all measure differently.
Thus I do not understand those who claim that the calibration curve that is circulating is universal to all the RS Meters out there.
Finally, I put the RABOS meter against the RS meter, and the RABOS meter adhered quite closely to the RS calibration curve, i.e. the RABOS did adhere closely to RS meter after calibration.
I therefore feel that the RABOS meter is quite accurate. Also, the RABOS meter is specifically designed to measure bass tones from 20hz to 100hz. The RS meter is essentially a broadband sound pressure meter.

That would mean that the RABOS might be as random as Dick Pierce claims the RS meters are, since they all measure differently, no? Who's to say your RS meter is accurate after the corrections?
Or, if you assume, as you do, that the RABOS is accurate, we must assume that the RS meter w/ universal corrections is also, since it corresponded closely with the Rabos.
Anyway, that's an interesting unit, I'd like to learn more about it. I agree that all those bass tones are useful, and that it would be good to have a unit optimised for bass, if that's the case.

My point exactly. But I think that since Infinity designed the RABOS as a bass equalization system that includes a parametric eq (in the speaker) and the meter and test tones to measure the bass, that it has a much greater possibility of being accurate than the RS meter which was designed to measure broadband noise and not individual tones.

...as the T-Rex footsteps from "Jurassic Lunch"... shook my room...and they're supposed to be 12Hz signals.
I, for once, think that the T-rex is being hyped too much by the media. 12hz footsteps ?!, how come ?, It's just a tall and fat animal, that's it.
I don't think Apolo 13 launch hit so low.
