The mic may be at about 10 deg off axis as it was set in between the P830986 and the XKi exit aperture.
Hmm.. You must have got a good one (or two), I bought a carton of about 200 for an install and used about 180 of them and then I tried to find a use for the remaining drivers but from memory they had a nasty peak in the top end which can be fixed with a notch filter, but that's extra cost .. along with the BSC circuit ... and limited x max..
A member turned me onto this blind listening test for op amps. Great work Mooly!

Sound Clip Library for Comparing Ref Studio Monitors
Someone did a similar listening virtual audition of studio reference monitors by recording them. Very cool.

Nice find!
I wanted to have a listen to the new monitors Presonus launched with great fanfare, none of them available here.
Glad I had a listen there... absolute rubbish! Add it to the pile of Presonus crap they have come up with in the last couple of years. They really lost their way.

Check out the reviews of the budget JBL LSR305. I can't find a bad review or actually a non glowing review. This is for the M2 waveguide which everyone says is magical. Powered by a class D TDA7492 I think. $225/pair on sale $300/pair regular.
Yeah, I noticed. but it's bigger sibling sounded better, in that test anyway.
The LSR305 is $500 here, never on sale.
Audio stuff never gets on sale. Even if it has been sitting on a shelf for 5 years, and the product is discontinued, it will still be full price, the one suggested as full price, not "street" price, fully wrapped in original packaging and no possibility to demo it.
No returns under warranty either, unless all the screws and components are falling down... They'll call the main distributor, and if they say ok, I'll get a refund. If they say no, the vendor sends me home, with or without the defective unit, no refund.
Come to think of it, I might be able to open an audio shop here and offer real customer service. That'd be a first! And I might be popular!

Year, they're about $450.00 a pair in Canada (before taxes) and rarely, if ever, go on sale (though I think customer service is at least a little better than perceval reports)
Not the tda7498 I remember, but more like a ddx version, full digital, meaning some sort of signal conversion befor amps. Similar to spdif/toslink only input Hifimediy amp I have. But haven't looked at those JBL for some time.
Look at closeup photo of take apart review here and compare photo of amp to TDA7492 IC. Blurry but the package and other marks match quite well, and given 41 watt rating allowed me to deduce 7492 as the amp used.

Here is the photo from above link - zoom in on class D amp in upper left corner:
Compare here with photo of TDA7492:
This particular unit is using bottom side conduction to PCB vias for cooling heatsink. JBL was very proud of how they saved money by not needing a heatsink on LSR305 to get a cost competitive product.

Chip is STA something, you could also see a clock/crystal/oscillator?? and a adc/dsp??? near bottom below STA chip
Chip is ST Microelectronics.
TDA7492 50 W + 50 W dual BTL class-D audio amplifier - STMicroelectronics
Datasheet:

I doubt they are applying DSP on this budget speaker - they would have bragged about it in features and propaganda. Timer xtal may be for microcontroller to set gains etc and turn/on off thump control.
TDA is part number ST logo is brand. Are you saying it is not an ST made TDA7492? What chip is it then?
