Has anyone ever used the Mackie SRM 350 as a delay speaker for SRM 450
mains. This is for voice only. If so, did they work well?

I haven't done it with the 350 but with more 450's. I don't see any
reason why it wouldn't work provided it was for the right type of gig.
What type of event are you reinforcing speech for?

Their primary purpose would be AV applications where the 450's are at FOH.
They also could be front fills if need be. I would like to have something
where they are sonically close to the mains without additional EQ in the
vocal range. As always in the AV business set up time is a huge issue.

I would go with a unpowered option so you dont have to locate and run ac to
each delay box
less wires to dress/hide/deploy/strike

What you propose would work fine. George makes a good point about
using powered boxes. The other issue I'll raise with powered boxes is
that if you don't use your own power distribution from a central point
and you instead use local power outlets, your chances of ground loop
noise increase substantially. If you do go that route, make sure you
purchase some 1:1 line level isolation transformers in the event you
do get noise.

More of the same type of speaker is always a better option regardless
of which speaker you are talking about. That way the response will be
identical. Even with great EQ giving you matched frequencies, a
different crossover or impedance can produce differences in attack
which are impossible to compensate for. IE they sound different. The
350 and 450 are very different beasts. An old 450 is way different
from a newer one too.

Sticking with active means the crossover comes before the amp, not
after it, which is what you get with any passive system that is not
amped per speaker. Wire count is not a big issue. It is no worse than
running a long mic cable. If that much work bothers you, then you are
in the wrong business.

1:1 iso transformers should be $40 but they are not usually that
cheap. Many people ground lift instead, but I prefer a third option,
which is to run safety ground wire only along with the XLR. I normally
dont hook them up unless I get a ground loop problem. When I do, the
end of the safety wire has a 3 prong AC adapter for ground lift on it
that I can just swap out. All the safety wires run to my distro. Each
has a 3 prong plug on the end of it that only connects the ground.

I disagree. Different models and types of delay clusters are
frequently used even for large shows. Last outdoor festival I did the
mains were V-DOSC and delay clusters were KUDO. Fills were ARCS. Amps
on the mains were Crown Macrotech and L'Acoustics on the rest. Very
different beasts, yet the performance was fantastic. Many others tours
and shows I've done have used mixed format mains and delays fills. It
is neither practical nor necessary to use all the same box in these
situations.

I've seen this mentioned regularly before, and I've always wondered if I've
got the terminology wrong or if this is really the way you do things in the
US.

I assume "tie in" means connecting bare copper wire inside the box with the
circuit breakers? (No idea what a "company switch" is, and I assume "sub"
means a box with circuit breaker that is connected to the main circuit
breaker box?)

Doing that is actually illegal where I live, unless you are a certified
master electrician. On the other hand, I gather that there are "electrical
inspectors" in the US, which we don't have. Are you required to have one
come to every gig to check what you've done?

I had a 32A single phase one installed for the amp rack at my local venue when
they did a re-furb last year. The local electrician called it a 'Commando' type
on account of the UK trade name for MK's version of it.
