JBL Array 880 Review (Center Speaker)

[dasdoing]

this layout requires waveguides for the woofer to result in constant dispersion, else lobing will ocure before the crossover: https://www.production-partner.de/test/line-array-test-seeburg-acoustic-line-galeo-c/

now this might only work in a distance?

on the other hand even 60 degrees at the narrowing should be enough; because beeing outside of this angle would mean to be on the right of the right speaker. it is reproducing manly speach anyways

I have read some places, that somewhat narrow dispersion of the center is a good thing,
Contrary to what we are mostly saying in here.

If creates a pin point image that is centered in one location only, even if it suffers a bit from angles left and right of center.

In my (limited) experience with center speakers, I want the center to have the same reflection profile as the speakers flanking it. Otherwise, it sounds different and can call attention to itself. This breaks the immersion and takes you out of the movie, causing you to think about the speaker you're hearing.

Comparing this to the jbl M2 looking at THD and 2nd harmonics over 1.5khz is this better then the M2?

If so is this attributed to the 880 array splitting the work between the compression and super tweeter vs the compression in the m2 doing all the work?

Probably. There is a quote from Greg Timbers comparing the very expensive 4365 and 4367.

JBL 4367 first listen - Page 6

Just got them in today. The large packing containers insinuate the speakers are much bigger than they really are. They are easy to un-box and one person can do it although two is better. The multi-lingual owners manual is about 3/8's of an inch thick although only about 4-6 pages of it are...

“The design goal of the 4367 was to equal or surpass the performance of the 4365 in a smaller enclosure and for 1/3 less money! Done and Done”

The 4365 was K2 S9900 level Mg compression drivers instead of the Al ones in the Array 1400/800. We know the ear isn’t as sensitive to distortion but the Mg and Be diaphragms have some of the lowest measured distortion.

The biggest disappointment of the Array lineup is the soft touch plastics that they used which “gum” up in many households…

But based upon this, the 4367 and M2 were NOT cost-no-object-flagships. They were flagships of engineering where price/performance was still important.

Lets disregard their design and products objective in regards to cost and look at the outcome and performance.

Does the 880 array have better THD in the treble and mids then the M2?

Also is there advantage to THD of the compression driver if the crossover is higher, on the 880 it's 1000hz and the m2/4365 its around 700hz. Does it help?
