It's been a while since SRX was considered top notch, is this the final move towards a purely MI product, or can we expect some long-needed magic from JBL?

(I already decided I want them, and desperately hoping they'll blow me away :nod: )

The 3 way cab and the double 18 cab look pretty cool. Disappointed they didn't do powercons .... Only time will tell ... Decent price point even at map....

Per, I think we have all be clamoring about a powered SRX cab for ..... oh .... about a decade now ;)

I look forward to hearing them .... or to hearing you tell about hearing them (which ever comes first). What is sad to me is that they didn't do this long ago..... when neo was cheep .... and everyone was upping their game in the powered speaker department. I think there would have been a market for them even along side the PRX lineup.

Personally I prefer more material in the compression driver, which is generally what you get when you move up the food chain. With a 3" VC and 1.5" exit, I wonder why JBL chose such a high crossover point (1900 Hz for the 12" box). I see several designs crossover around 1,200 in that configuration. In fact, their old 700 Series passive box, the 712M, crossed over at 1200 Hz. That's roughly 3/4 of an octave lower than the new STX design.

Full disclaimer, I've not heard the new boxes.... just waxing philosophical.

I actually take that as a good sign. 1900 is probably the point where the horn pattern matches the Mid dispersion the best. On a 12" it will be at a higher frequency like that. It means that the dsp and amp modules aren't "one size fits all", and they actually have some thought put into them, instead of bean counters making them more modular (and profitable)....

The 815P crosses over even higher at 2000 Hz. And the DSP may be programmed differently between boxes, but they are absolutely "one size fits all" in the sense that they are using the same amp modules. It would be silly not to be.

Well that sucks then...

They are probably setting the XO point at a place where the power handling of the horn driver can "keep up" with the power handing of the woofer then. That would be a bad sign....

But what do I know. I'm just guessing at this point....

I am awaiting a hearing of these myself, but my understanding is that they are a more V5 tuning, I believe using FIR filtering. The V5 preset for the STX812 is higher than I would have thought for a 12" 2-way box at somewhere in the higher teens, as I recall, but does sound very sweet.

I am an MRX series owner and a STX series owner.. strictly subs though.. I have listened to the SRX828S powered speaker and while it looks just like my STX 828S subs.. performance is just about the same as my MRX528S subs.. they just don't put out like the older SRX or the new STX line. On paper these ought to be better than my Passive STX but I assure you this isn't the case.. at least this was my experience with them.

That's not totally surprising. The amp module on the specs says it's 2000 watts PEAK power. Dig a little deeper into the specs, and it's 2 750 watt continuous amps, one for each driver. On the SRX728, that would be barely enough power to wake the cabinet from sleep. The STX has a peak rating of 8000 watts. That's significantly more than this new sub has to offer.

Of course, it's extremely likely that JBL put an amp inside of the cabinet with reliability in mind more than maximum possible output. If you put an 8000 watt on a sub rated at 8000 watts peak and let a DJ use it, it'll last about 10 minutes.

Then again, you could also apply the correct limiting solutions and thermal protection...
 
Re: SRX 800 - the real deal?

For us yes but when they sell them to said DJ so he can provide his own equipment. What's cheaper? Smaller amp or limiting functionality?
