I agree.

I'd say it would be easier to quickly replace an amp if there was a
spare
already in the rack, compared to climbing up over the heads of patrons
and
replacing speakers out on the club. A distributed system does provide the
option of shifting sound levels out in the club if it were a bigger club,
but in a club that small, I don't think there is any advantage to it-

You make a good point about which replacement would potentially be
easier. However, in my experience, using a passive crossover and an 80
watt amp in comparison to the 150 watt biamped active crossover style
studio monitors I'm suggesting, the active speakers will often sound
better.

I use these daily. I've also used the suggested Behringer Truths
(which are more cost effective, and sound pretty darn good for the
money). The Truths have the problem of crossing over between an 8" and
a tweet, so there's some funkiness in the midrange, but not enough to
be all that noticeable.

With what you're suggesting, the whole system goes down while you
replace the amp, Mike. With what I'd suggest, one speaker goes down,
you wait until close, and swap it out. Why would you bother working
over a customer's head while you're open? That's just silly... unless
you have no choice but to shut down because the whole shooting match
has died... which is more likely in your suggested scenario.

If an overhead speaker in a distributed system goes out, it creates a dead
spot that may be very annoying to the customers sitting under it, and either
you replace it or you have annoyed customers all night. If a power amp goes
down and you have a spare in the rack, you're down for less than two
minutes, tops while hooking the spare up. Also, good quality commercial SR
equipment is very reliable. In the thirteen or so years I managed night
clubs, we had equipment failures that shut down the sound three times, and
two of those times we were back up and running in under three minutes,
counting the time it took me to get to the stage and figure out what was
wrong (once was a power amp, once an EQ) The third time was the house mixing
conole, and while the band had to quit while I hooked up the spare, I
unplugged the DJ mixer from the house board and hooked it directly to the
FOH EQ, and we had the DJ going in three or four minutes.
There are advantages and disadvantages to both types of sound systems, but
a standard FOH type system is much easier to get sounding good than a
distributed system is, it's more efficient, more reliable in the long run
than powered house type systems, it has the advantage of being able to be
used for live music, there's less wiring to be run and installation is much
easier. The FOH system will be capable of higher SPL if it's ever needed and
there's less likelyhood of phasing/timing issues cropping up. If the
distributed system isn't set up correctly, it is likely that there will be
dead spots at certain frequencies all over the house.
It's Brian's call, but if it were me, I'd go with the FOH type system, it
will be cheaper, easier to install, more versatile, easier to get a good
sound with, and easier to correct any sonic problems that might show up
during installation and testing.
