I see a handful of these used locally to me, but not sure if they're a
good speaker for me. Are they power hogs? I'm only using my Yamaha
P7000S for both mains and subs (700W/ch @ 8ohms and 950W/ch @ 4ohms),
looks like it wouldn't be enough to power the JBL's.

They don't make these anymore I assume, not sure how old they are.
Any gotcha's to look out for? Selling for $700 US /pair. Fair price?

And again I leave soooo much info out of the first post. We're a
medium volume rock band, we mic everything including guitars and keys
(usually only kick+snare for me tho), and per a previous post I picked
up some Yorkville PS18 subs last week (300W program). I have two pair
of EV Sx200's that we use for mains and monitors, but interestingly
one pair sounds sweeter than sweet, and the other pair has a little
boxiness to it and not sure why. Maybe I got a first gen and a second
gen of the series or something? Still a good sounding spkr just the
same, but I can always use them as extra monitors so looking for
something real nice for the mains that won't break the bank.

No, it'll probably just break the tweeters. And again and again and again.

In the end I put a P-Audio 40/50W driver in one JRX floor monitor instead of
the toy it was fitted with. But we've lost confidence in them so much that
they are held in reserve only.

Actually, it doesn't use the same HF driver but I wouldn't touch economy JBL
cabs with a bargepole now. Plus it has NO tweeter protection (not that it
works on the JRXs anyway).

Why are you discussing JRX series when I posted about the SR4722a
series? I'd say apples and oranges..

Probably made in the same factory in Asia. The pricing indicates a similar level of
likely (in)competence.

Look at my link. If you don't understand it, find someone who does. NO tweeter
protection. I fit tweeter potection on every single one I use or design in. Plus it
looks like only a 12dB/octave crossover which won't help much either.

Graham, the SR4722 is an early 90's box that was discontinued long
ago. That said, it was a fairly solid box made with good quality
drivers. I believe the 12" driver is still in production at JBL and
available for sale. It was also used as an OEM driver for several
other companies boxes. The compression driver, while decent, has been
out of production for a while. The box was designed and built in the
U.S. JBL factory. This box is likely leaps and bounds better then
anything offered in the JRX series and is probably an ok buy for the
money if it's in good shape. 12dB octave crossovers are the norm for
boxes in that price range. Crossover components to build good 3rd or
4th order designs tend to be cost prohibitive in that particular
market. The best solution is to bi-amp and use a decent external
processor for optimum time alignment, EQ, and limiting. FWIW, most top
end sound reinforement boxes have no crossovers or tweeter protection
except for the self powered ones. Non-powered multi-way/multi-amped
boxes require all that stuff externally.

Thanks for the clarification. That does put a different perspective on it, although I
wouldn't use a box with a crossover freq as low as 1.2kHz (bang right in the critical vocal
band). I'd still be worrying about those tweeters. Still, replacement diaphragms seem to be
well available (maybe they're regularly needed ?). Best price I saw was ~ $110

The SR is a bit more solid.

$110 for a diaphragm sounds a bit silly when you can buy a BMS driver,
likely better, for about that.

I've had bad luck with aftermarket diaphragms. The exception being Radian.

Agreed. The Radians are pretty good. I've used them in my TAD's when
the OEM replacements were either scarce or money was tight. At about
1/3 the price of the $600 TAD beryllium diaphragms, they're not bad.
The TAD's to go up a bit higher with better sparkle on the top end,
but the Radians are a bit more efficient.

I actually like the Radian better than I do JBL titanium phragms. Don't say
that on the JBL forum though- they have a short fuse for what they consider
sacrilege.

Have noticed, sometimes the Radian doesn't seem to handle quite as much
power, the exception again being small Altecs, the Radians hold up way
better than factory.

20 years a go I made a decent second income selling replacement Altec
phragms. They blow up real good.

Large format altecs are much better. The old Alnico 288-G series is often
called the "Poor man's TAD."

At what they sell for on FeePay though, doesn't make sense for live use.

The Altec 299 is a VERY good sounding driver, IMHO way better than JBL's.
And they can be bought reasonably.

Hated to see what happened to Altec, so many manufacturers make cheesy
product, sad to see a quality company killed off.

Tell me about it. That's why those JRXs ended up with vastly larger P-Audio
drivers I knew could handle it -AND a protection bulb that was correctly rated
instead of the joke devices 'JBL' installed.

If they're anything like as badly made as the JRXs, (and for the price it
sounds like it) avoid them like the plague.

IIRC these date back to the mid-90s. Might predate the "lets manufacture
