Hi folks,

I'm helping to organize a work party for a room with the dimensions
72' x 39' x 14' (L x W x H) for 150-200 people max.

We'll be spinning house and other electronic genres, and we want a
decent club atmosphere.

I rang a rental place earlier today and they recommended:

two x Mackie SRM450
two x Mackie SWA1801

I've played on/and heard a pair SRM450s at a couple of smaller
venues,
and I was thinking more along the lines of:

four x Mackie SRM450
two x Mackie SWA1801

In your expert/experienced opinion would my suggested setup using
four
x 450s really be too excessive?

Thanks for your time!

Scott

For that many people - I think the rental company's option would be
just fine. Work parties go like so: during the first hour 2/3 of the
people are pissed that your so loud. During the second hour 40%
leave, and half of them get their drink on and enjoy it. Durig the
last hour the 30% that got their drink on will continue to party hard
and love everything your doing. So REALLY you need to cover 50-70
people - and a pair of 18's and mid-hi's will do that fine. If you
REALLY expect 200 people to be jammed on the dance floor digging every
minute of it... then George is right you could use 4 tops & 4 subs...
but that ain't gonna be the case. 20 years of gigging would have me
bet some good money on that.

and 30 years of sound I would bet "some good money" that the band will be
late
but I won't be

he is much better off haveing sufficent PA on hand rather than betting on
50-70 folks

bTW did you notice he is spinning "house and other electronic" styles
this indicates to me this is not the typical"company party" as your
describing and the styles he is presenting are typically supported with
excessive bass

When I say work, the 'workforce' consists of 1000+ people in their 20s
to early 30s, about 100-200 people are the party going type and will
turn up with like-minded friends. So we're expecting about 200-300 at
the party.

Realistically at the absolute peak I expect no more than 150 on the
floor at once. On average, yeah it'll be way less than those numbers.

I just hit the budget limit for equipment, can't get 4 tops and 4
subs, so probably going to have to go with:

2 x 450 (playing full range)
2x SWA1801 and 2x 450s (wired through the freq cut off of the subs)

OR:

3x SWA1801 and 3x 450s (wired through the freq cut off of the subs)
not exactly stereo...

Incidentally, the rental guy said he played in a band with 2x SWA1801
and 2x 450s to a crowd of 700 people...which I thought was
surprising...I guess the music he was playing was no where near as
reliant on bass as the tunes I'll be playing...

I also have the option of swapping out the 450s for JBL EON G2s, or
passives + amps

Budget is $300 for speakers (inc amps) see what you can come up with

I would get 4 subs and two tops
positon(2ea) in corners at end of dance floor to get maximum support for
the bass from the boundry effect

you might want to check out some "lower level" sr companys who would deliver
a much more suitable rig, wire it and remove it for that budget
your renting from a pretty upscale house

Bang-zoom. Now we're talking. 4 subs and two tops. George and I
have met at the crossroads. Another thing to note on the Mackie 450's
is they're 90x45 horns... not arrayable - so how you would've worked
in the 4 tops anyway???

Also about the SR companies... in my area you could probably get
somebody to drop you a well powered JBL SRX rig w/ double 18's for a
few hundred bucks.

If you really want the club atmosphere I'd go for more subs too.
People across the room won't care as much about not hearing the music
if they can still hear/feel the thump.

plus if you can get the 450's up around 8 feet , they will deliver plenty of
ear shredding

I'd do the double 18's w the double 15 tops, separate power, x-over,
and the smallest mixer they have. A pair of double 18's will
devestate 200 people in front.

Go with 2 tops and 4 subs if you can for the sort of music you are playing.
450s are not good full range and you will not get much low frequencies out
of them.

Hi guys thanks for all your advice.

The party is this coming weekend.

Based on your tips I asked for:

2 x SRM450s
3 x SWA1801s

yes, and we had money left for lights....so I got some of those too.

Unfortunately, the rental guy said they only had two 1801s...I told
him about this web discussion and multiple suggestions of getting more
subs. However he was insistant that the 2 x SWA1801s would be killer.
I reminded him I was playing house. He said it would still said would
be more than enough for a room/audience of that size. He said that the
SWA1801s were way way better than the SWA1501s and other powered subs,
describing them as devastating when setup correctly and placed on the
floor.

He did offer a full passive/amped setup with dual 15" and the dual 18"
as suggested above, but said that would be far too excessive and serve
an audience of 400-500 rather than the 150 person peak I expect.

Your rental guy is correct - do as he says. Just use the built in x-
overs in the subs. This is plenty of thump for a band or DJ at a
party the size you decribe. Many of your party guests will be weenies
and bitch about the volume anyway so bringing more stuff would be a
waste. Re-read Erich's first post - it's dead on.

Put the subs against a wall / corner or right next to each other and
you'll also be able to get a couple dB more out of 'em if you need it.

he really doesn't have any choice

yes if you want to sound like a dj playing through whaat ever he can scrape
up rather than what will deliver
I've done thousands of these parties
most with a proper system, some with a undersized system
my rcf 1018's are "very" similar to the mackies, except mine are passive ,
not powered
if "I"was presenting house and electronica, "I" would want room filling bass
not just loud bass, 4 subs will be nearly insignificantly louder than a
pair, but they will be substantially "fuller"

be sure you cut these sub off at around 45 Hz , you may want to dial in a
hump around 90Hz the make people hear what they think bass sounds like

Many of your party guests will be weenies

like I said more stuff is not about more volume
its about getting the same volume without the distortion, or heat related
compression that these speakers are sure to experiance
so in the end the crowd will have fun even if you were playing without any
subs
2 subs is marginal, 4 subs are good, 8 subs and you would be a legend
