Gotcha. Thx.
Looks much more like what's to be expected.
REW simply must have had a hard time latching onto impulse timing at your listening position.
It does fine with comparing impulse response timing, left to right, down to a single sample time, useful for positioning the measurement mic.
But the above measurements are old, so, can't say exactly what was done any more.
Maybe I'll make a new set of everything one of these days.
Uh huh.
All that has changed since then is the version of REW, though.
BTW, a couple of asides........I don't like to use gating either.....and nothing to do with meas, am a CLS owner
My Audio Buddy has a pair of CLS with Rythmik subs and a big Parasound amp.
His room is about twice as long as mine.
My initial audition of ML was with a pair of SL3, in a backroom showroom away from the pedestrian stuff, maybe 60 feet long and 30 feet wide with 20 foot unfinished metal truss ceiling, with the speakers on a little foot high stage at one end, with 500 watts of Krell KAV, eventually running wide open after the Salesman foolishly left me with the remote when he had to answer the pager for something happening up front.
Loud and clean sold me, sounded more like a band than speakers, though I didn't get a pair till later in another city. In 1998 upgraded to the reQuests at that shop though, when they had an "every" speaker sale - buy one get one half price...
