im planning on gettin my first PA system. I got asked to do a small concert to promote a young rap group at campus along with an afterparty later. prolly 100-150 ppl. would a couple of PA speakers with:
15 inch woofers & horns
Rated at 1500 watts at 8 ohms each.
Two heavy duty speaker stands that extend to 6 feet tall
1/4 inch and speaker wire inputs.
...be good enough?? or should i go smaller??
and would a 700watt 15in sub be smart to get also??? or can the speakers get the job done by themselves??
finally what would i need for and amp??
by the way i got 2 dns1200 and dnx120 mixer.
THNX!! =]

Well i personnaly have only one rule for this kind of problem.
You can never go too big. BUT you CAN be too small.
I rather have more than not enough.

Number one rule: It's not the wattage rating that counts - it's the sensitivity (Decibels per watt).
Cheap speakers will generally give you less volume for a given wattage than mid to high priced speakers.
Ergo it's false economy to buy cheap speakers because they won't give you as much volume per watt.
Rather than look at the amount of watts a speaker claims to handle, check the maximum SPL.
Anything rated at 127dB or higher should do the job without any trouble.
It's always best to use a sub when playing music for people to dance, as it's the low bass that triggers that primal instinct!
Speakers that claim to be "full range" rarely provide enough bass, as the cabinet size is always a compromise.
Moulded ABS cabs also don't help to provide a nice warm bass - wood is best.
So my suggestion would be to use at least one wooden sub cabinet.

All good points.
It is also worth bearing in mind that if you use a good quality sub you can use smaller speakers for your mains. 12" units are normaly more than up to running with a sub.
If your speakers have Jack type sockets make sure you always switch the amplifier OFF before plugging or unplugging your speakers (This is good practice anyway but is very important with Jack plug connectors). Jack plugs wil cause a temporary short circuit when they are inserted and pulled out. This can cause damage to amplifiers.
Having Jacks and binding post connections can often be a sign of a cheap speaker. Look out for speakers fitted with Speakon connections as these tend to be more robust and relyable.
Amplifiers as with all things are built to a cost. Watch out for power quoted in max or Peak these are not realistic figures and can be many times higher than the actual ability of the amp. Look for power figures quoted in RMS or average power into a specific speaker load ie 250W RMS per channel into 4Ohms.
a recomendation for amps of good quality that don't break the bank would be QSC GX3 and GX5 and also the new Crown Drivecore amps.
Don't be afraid to look for good quality second hand equipment.You could well be better off buying good quality brand name gear As long as you can confirm the condition before you pay for it you should be ok.
Good luck

I have a set of yamaha br12 speakers with a yamaha emx62 amp. It sounds good for about 100 to 150 ppl. It is decent, doesn't have the bass that I would like. I am going 2 add a sub 2 it later, (after a few gigs 2 get the money) And then I'm gonna save up and buy a better system.

Hi mate
Not a Gemini fan i'm afraid. I think you could do better spending your cash on a good pair of used, branded speakers from a reputable dealer.
Twin 15 units have become poular with DJ's because of the extra bass provided by the second 15" driver. There is a problem though! Good ones are fairly heavy so not easy to move around. They also have to sit on the floor which causes problems when trying to cover a room full of people. Once the crowd is in. The speakers sit lower than the people are tall. This means that the sound is banging into them. You end up with a situation where the people at the front hear everythin too loud and the people at the back hear bass and very little else. You can get round this by lifting the units off the floor but while this will increace clarity the bass can suffer.
By far the best system for smaller gigs is a Sub and Sat system. With this you have a single or pair of bass only units which sit on the floor and a pair of smaller units mounted on stands which provide the mid and top frequency sound. The great thing here is that you can get the mid and treble sound up above head height and provide far better coverage in the room that you are playing in.
For a smal venue (100-150 people) a single 15"sub and a pair of 12" + Horn sat speakers can do a great job with as little as 500 Watts split 250W Sub and 120w or so to each sat speaker.

Forget about watts n such at this stage, I think you better off hiring a pair of full range speakers and a pair of subwoofers. You can get it done with just tops but to 150 people it will sound as hard as hell.
