Let me add that by dated I mean that ( A ): It is discontinued and ( B ): The box is a pretty basic design where only the parts within it make it what it is. Reason ( A ) is something to think about in the near future in reference to parts. Parts are going to eventually get harder to find.... So yes, it is dated. I don't think the SRX 700 series is a major step above other similar options available now. Same price you can get a passive 800 series speaker. The newer 700 series PRX line is a pretty close contender to the SRX 700 stuff, both in output and quality of sound.  You also don't have to buy an amp. So while yes, the SRX 700 series is very good by even today's standards, it is not punching above its weight and is expensive in comparison.

I say stick with what you have until its demand and value drops a little more. The 728's are still very much on the want list and the others in that line still have some desire. Most won't say no to it and who knows, maybe in a few more years there will be an even better less expensive option?

The SRX712, 715 and 835 have a 3" HF driver. The SRX725 has a 4". The VP HF driver is 4" but not the same as the 725

There are advantages and disadvantages to each a 3" and 4" diaphram HF driver.

So "it depends".

Generally, a 4" diaphragm will handle more power and go lower in freq.

A 3" will typically have a better HF response with breakup modes that are higher in freq.

Also a 4" is typically found on a wider exit driver.

This can be a bad thing if the coverage pattern is wide.  The higher freq will not be able to "fill out the horn"-so the coverage may not be as even-across the whole freq band as a smaller diaphragm/exit driver.

But many people wrongly "assume" a 4" is "somehow better".  Not necessarily so.

As Ivan states the diaphragm size will mostly determine power handling capabilities and frequency response. The critical part of the assembly will be the horn, it's horn to driver coupling size, the horn dimensions and shape.

I was only pointing out the sizes of the HF in the various models. Not that one size is better than another.

The 712m has an elliptical CD horn whereas the 812 has a more conventional rectangular higher aspect ratio horn.  As Ivan often points out, narrower patterns required a larger mouth, which makes me leery of the new speaker.  It should lose vertical pattern control at a much higher frequency than the horizontal.  Which means more upper mids bouncing off the ceiling.

I am very lucky to run a house system every weekend with stx835 flown over stx828s.  I am going to be adding Srx 835p and SRX828P to my inventory in Q1 2016 and I hope these reports will reflect my experience. 

The STX is a joy to run, articulate and effortless I can't say enough good about it.   It's simply driven with a  PL389 driving the mains and two bridged pl380's on the subs.   The only thing I wish is we had more processing a DBX drive rack takes care of those duties.  Here are a couple of videos and pics.  You can see how they are flown.

Didn't JBL used to provide polar plots? I can't seem to dig any up for the 800's.

Mostly for the install boxes. And a few others.
