I need your help in finding a subwoofer...$200-$500 for banquet hall size performance..Any suggestions?

What does the rest of your system consist of?
Do you have an amp for the sub or do you need a powered one?
Do you have an external crossover or will the sub need to have it's own?
That price might get you a semi-decent NON powered sub with no crossover built in.

There is a little more info that needs to be known before recommendations can begin  :yes:

OK...Im a Rookie at this so forgive me......I purchased a Voco Pro Club 6800 600W Club system(before I started investigating opinions on this site...so forgive the errors of my ways but I have too much money invested to dump the system for the amount of time it gets used by me..personal performance only) My mikes run thru a Thompson Vocal Eliminator (richer sound) into the mixing board..I need a powered Subwoofer..Have no clue(call me clueless)about the crossover..Should have consulted the ones in the know I guess before I invested the money..Any help would be appreciated.

Well looking at that sytem it looks as though you have the VocoPro KJM8000Pro mixer?  This one supposedly has an adjustable subwoofer output so no need for an external crossover.

A little more than your budget, but you aren't going to find a decent active sub in that price range.  This will compliment what you have fine & work well in the hall.

Thanks Lonman............Your always a wealth of information...I appreciate it!!

I use a Yorkville y118pw powered subwoofer in my set-up, you can plug it into a main speaker to catch a signal, and it doesn't require a crossover. It is their value priced line, I'm satisfied with it for rounding out the sound. It has a built-in 200 watt amplifier with a 18 inch eminence speaker. It costs $489.00 at www. musiciansbuy.com

Well there you go, bass on a budget.
However, don't connect to the speaker output - use the subwoofer output on the mixer - you'll yield a better signal & sound.

Believe it or not the owners manual on this particular subwoofer tells you to either plug into a main speaker or a mixer and shows a diagram to do so. I myself thought i would get a clearer, more robust sound if i plugged it into the subwoofer out on my mackie-cfx mixer but i couldn't get the volume i needed that way. It's a mystery to me why, i even bought balanced cables but it didn't help. I get a louder output plugged into a main speaker.

Then something wasn't wroking right on the line in on the sub or sub out on the Mackie.  That is a hot output - albeit a fixed frequency output - it is a good frequency that will not allow any mids or highs through - which is perfect for a sub.  
I know hooking up into a speaker level input does work (when provided), but it will not yield a cleaner sound than a standard line AND COULD possibly damage the amp that is driving the main speakers if something shorts out in the subs amp - i've seen this happen in car stereos on occasion.  Speaker level input is only supposed to be used as a last resort.  Also you are probably getting a 'fuller' sound possibly because I didn't see if the sub had a built in crossover or not )which the sub out on the Mackie is - a low pass filter (crossover component).  If not - it is trying to reproduce all the frequencies that your main speakers are.  A sub is only supposed to reproduce very low end frequencies - if you can here anything more (ie guitars, vocals, anything that you would heard out of high frequency drivers) than low end bass & kick drums, it as no crossover connected & isn't doing what it's designed to do & again you could end up hurting the sub itself over time.

  I second the above, and like it.  It's simplicity will serve you well. However, I only use it in when I have to run a straight DJ show  ( for the money only- I would rather host karaoke).  I never use a sub for karaoke as I don't like how it sounds with amateur vocals...

Again, if you are hearing vocals through the sub, then it is not crossed over correctly or not at all.

Personally, if I were using subs, I wouldn’t want the tops to get a full-range signal; I’d want the sub’s crossover to ease that stress on the tops.  

Nothing good about having the subs and tops trying to reproduce the same frequencies, it‘ll only cause mud.  

If the subs have internal crossovers, I’d run through them to the tops.  

JMHO.

And I agree that when I’m doing karaoke, unless I had really small mains (which I don’t), I don’t like to use subs, either.  

Any good 15” main, even 12”, would do the trick, unless you were really going LOUD.  




Music… that’s another story.

Karaoke IS music.  Why not give it the same treatment as dj music?

  First, to clarify a previous post.  The vocals aren't heard from the sub, I just don't like the mix of sound, and what the extra base behind the vocal does to the total effect.

    This is the key difference between running a DJ show and hosting karaoke, and why so many good DJs produce some truly rotten karaoke..

     In a DJ situation the emphasis is on the MUSIC,  and in karaoke the emphasis is on the VOCALS, enhanced by the music. The mixing styles between the two are very different. In karaoke, there is no true "setting up" of sound. Since the emphasis is on vocals, and each singer is different, a host MUST know how to mix on the fly, changing with every singer. This is also why that terrific Sennheiser mic used by a trained DJ is one of the worst choices for karaoke.  The DJ trying his hand at karaoke thinks he's doing the singer a favor, but if the singer isn't top notch, every glitch will be amped by ththat very clear and unforgiving mic.

     So, I stand by what I said. I think subs are a must at almost any straight DJ show, but think they are detrimental to the mix in a karaoke show.  Please keep in mind that these are only my opinions. No need to go to war over it......

No war, just a HUGE disagreement there.  If the sub is run correctly ie proper power, crossover frequency & sub volume, it is a BIG enhancement for karaoke ( or any music for that matter which is why 90% of live venues use subs) - it doesn't have to be set up to pound people out of their seats, but to definitely fill out & allow the tops to reproduce the actual vocals & rest of the music that the sub isn't taking.  Karaoke is about the singing, but if the music sounds thin or bass lacking, that don't help a singer one bit - I like a full sound like you would hear in a live situation not just another karaoke place & that's my opinion as well.  I'm sorry to debate, but too many people got the it's only karaoke attitude.

It depends on the crowd At a teen birthday party or with a younger crowd they want bass. With older crowds at a country bar its not that important. But I do like to "feel" a certain amount of bass for certain types of music. It provides an unconscious energy to the crowd.. I know a couple of kj's that have bongos or those tall ones and mic them at karaoke shows.. When doing calypso or something they are awesome and really adds to the overall effect.

You'd really be surprised at what older (Not sure how old you're going here) 30's, 40's, 50's?  All?  People of all ages appreciate a good sound & again, just because a sub is in use, don't mean you have to turn the volume of it up to blow people off their seats, just round out the sound.

Yea I do too Lon I did do a 60th wedding anniversary one time and wasnt sure how loud I should do it. Luckily I did have some big band music. That started them then 50's rock was the most requested.  For rock you need bass and lights...

I have been kicking around the sub question for a long time. I am using Gemini "5 way" 15" speakers (I know there is no such thing as 5-way, but that is how they were billed to me). I am also Using a Yahma 110 10" as a feedback monitor. All of them are passive, and I really think it's all my amp (Audio 2000s) can handle. I use a Mackie DFX-12  mixing board. Is there a good low cost addition I can use with this Frankenstein system, AND, do I have to adjust the eq any differently when using a sub?
