Just want to find out where to upgrade. I'm sure some of my equipment won't work for this environment.

ALso want to know if an Alesis USB8, 8 channel mixer with separate lines for effects can handle a PC karaoke show. BTW - I have all the original disks. My music would be mainly to supplement what the company already has.

No vote.
It's not a matter of how much power a room needs, you should always purchase your speakers accordingly per speaker power rating.  You can use smaller speakers if you feel the need, but then you start losing your fullness.  If you have say a small 12" 2 way & the program power says it handles 400 watts, that's what you should get - regardless of the size of the room.  
This is a common mistake from people thinking it's a small room, don't need a lot of power.  
Using that 400 watt speaker example:
What ends up happening is you start playing & find yourself turning up the volume to compensate for the crowd noise, what happens - distortion!  It may not even be noticeably audible at first, but your speakers will sure feel it.  Then you start turning up a little more, now it starts becoming audible - why because you now over the 150 watts rating & anymore power that is produce is coming in the form of distorted sound.  Which will end up blowing your speakers.  You can blow a 1000 watt speaker with a 10 watt amp.
If you were running the proper 400 watts to the speaker, you more than likely wouldn't need to turn the volume up as much to get over the crowd noise & if you do, you still have room to work with.  Get an amp to match your speakers, you will have cleaner & fuller sound & won't need as much volume doing so!  Just because you HAVE the power don't mean you will need to use it, but it is better to have too much, than not enough!!!

My home PA system that I sold put out 400watts and was barely good enough for home use in my opinion & for a room that size.

I would go with atleast 1200watts & yamaha speakers to match....two on stands & two monitors for the singer.

But thats just my 2cents.....Listen to lonman  :D

Remember wattage is spoken in different languages.....bridged, stereo, per channel and at what resistance(ohms)...is that 150 watts x 2 at 8 ohms......????...usually when you see advertised 1200 watts, they're talking bridged.....

I normally had a 250 watt amp in my car stereo....and that was nothing compared to most people in our area  LOL  Most around here have 1000 watts in there car stereo and yeah those rattle the windows when they drive by.....250 watts you can here it, but it isnt any big deal  LMAO  ....unless you have the windows rolled up and have it turned up full blast....then it sounds good to the person in the car.  :D

At one time we had about 60-70 jukeboxes in various venues b ars lounges bowling alleys. Ive installed in about every venue possible using different speaker combinations to distribute the sound The old boxes had 50 watts per channel.. The cd jukeboxes at max had 100 watts per channel.. And yes we could rattle windows and the cocktail glasses hanging in the racks..... A 30X60 room to me is like a closet...


The acoustics of a room and the height of the ceiling (acoustic or wood) and the material of the walls and structure determine the wattage required ... In a room that size I can tell you how to have a larger spl at the far end than the middle but the general consensus here is more and more wattage... I can still put an old 150 watt Bogen PA (publicv address) system in a pasture and you can hear it in the next county.
Woodstock 69 had 3400 watts total There are still some of us that can plow a field with one horse and the newbies need a tractor with 1000 horse power engine...Of course everybody here thinks the old engineer is full of BS anyway.. BTW in a 30X60 room I could hang 2 JBL10 Eon G2's and blow away any system here. Not 15 ... 10"  

Oh well..........

karyoker....I think your a very smart guy & I know that you know what your talking about.   What you are not understanding is that people like me & some others have found through experience that "we" would not be satisfied with the setup that you are talking about.   Its because we are picky and I mean very picky!!!  For me if I compare the difference between a system with 400 watts and 10 inch or 12 inch speakers to a system with 1200 to 3000 watts and 15 inch speakers.....I will pick the higher Dollar higher quality system every time!!!!!  

 I dont care how good anyone can get that low wattage small speaker system to sound!!!!!   My standards are so freaking high that I know the better quality larger speaker with more wattage is going to sound better to me!!!!!   It isnt that I need 3000 watts for loudness....Its the fact that I need that 3000 watts to push four 15' inch quality speakers....So that not only would I have plenty of volume to play with but also I would have enough Bass response so that the system wont sound like some cheap azz Bose home theatre crap....which probably sounds good to you but doesnt to me....lmao

Karyoker....your Idea of loudness & bass response is no doubt different than mine.
Some people say.....thats too loud!!!!! it hurts my ears!!!!! while someone like me says...hey yeah!!!!! now that sounds Great!!!!!

Im so picky that I would not waste my money on anything less than 15' inch JBL or 15' peavey's and I would not waste my money on anything less than 1000 watts!!!!

Why??? I've tried that little crap and I dont care how good you are at setting it up and adjusting it...you can not do it any better than I can.....and that small crap will not satisfy my taste for quality sound.

Now before you go saying blah blah blah about your experience.....let me tell you that I once worked for a mastering studio so I dont want to hear about your Daw experience....Im so much more picky than other people I will only settle for certain things....it dont matter how much you can do with little speakers & little watts  LMAO

That little PA system will not please me no matter how much you adjust it  LMAO

It's like trying to say that your k-mart sparkomatic speakers and 150 watt amp is going to sound as good as my JBL speakers with 1000 watts....It will never happen In a freakin life time!!!  LMAO

I dont mean any disrespect here but different people have different standards, what sounds good to you may sound like crap to me.....thats all  :D

I think I'm getting the idea here. Lonman laid it out clearly and a lot of points were made that back it up. The higher power is not intended to over power the crowd, it is needed to give a good blend or balance. With the right power and settings the sound can be crisp and clear.

The one point I needed the most was addressed here too. An underpowered amp can still blow a speaker while trying too hard for clarity. Working against the natural frequency response of the speaker just to clean up the sound can force troo much of one band through the speaker to the point of blowing it. Meaning trying to make the speakers to recreate a sound that they weren't designed to make at decibels that they can't handle. A lot like sticking a knife into the speaker.


It was clearer when I was thinking it through but putting it to words is another thing.

Yall are talking about different animals. It is pointless to compare a hi-fi application to a live-music or vocal application.

Comparing one to the other is like saying "my Ford F350 is better than your Harley." They serve different purposes and can't really be compared!

My home theater receiver is 100 watts/channel with Infinity mains and a Sony subwoofer. Throw some classical music or a band like REM or Counting Crows on that system, and it sounds much better than my 3900 watt PA system. There are just lots of subtle layers to the sound that you just can't hear on a big PA. That is because it is a system designed to reproduce hi-fi sound, including all of the production and effects.

Then again, play some Ludacris on both systems and it sounds infinitely (pun intended) better on my PA!!

And no one is going to make a 500 watt system with two 10" JBL mains sound better than my PA system when the local alternative band singer is singing (or screaming), Pantera through it!!

LMAO Yes jesse I fully understand where you are coming from..  Lets put it this way and we have been down this road before... We have 4 JBL Eon15 G2's   2 JBL EON15 non G2's and 2 JBL EON10 G2's... We are going to setup in a 30X60 garage....Which speakers would you recommend?

Post subject:  Re: Is 150 watts total enough for a room at 30' by 60'?

For the price I would go with the ones I listed ubove LMAO
They are cheaper and would probably do a better job LMAO

But if i Had to use the Eons I dont guess it would matter :rotflmao:

:jk:  LOL

ok if that garage does not have carpet on the floor or walls and the sound would be bouncing around as if in a tin can then just use your home stereo  LMAO  or one of those karaoke machines from radio shack  LMAO

Im just having fun with you karyoker, Im sure you know more than I do  :D

Jesse, are you in bed with BigDog? You 2 are like 2 peas in a pod, both full of crap and everything that comes out of your mouth is me, me, me, me, me. Between the 2 of you, it is impossible to imagine anything bigger than your bloated ego.
