Topic: Advice On Gear...Subwoofers..??

Questo argomento è obsoleto e potrebbe contenere informazioni obsolete o errate.

Hello! I have a couple of behringer speakers that I would just "link" each one to a subwoofer through a speak-on to 1/4" connection. I would power them through a Behringer 2500 watt amplifier. One of my subs has starting peaking out one side of my amp so I've decided it's time to look for some new subs. I really don't know that much about the whole thing, I basically know what has worked for me up until now. I own two amps and a cross-over, but I want this to be as simple as possible. I would really appreciate any suggestions on what would be a good new route to go in order to sound as professional as possible. Thanks for any suggestions!

what is your budget? There are tons of options out there. Behringer just came out with some new 18" subs that are really nice BUT they weigh a ton @ 100lbs each.

Give a budget and are you looking to stay with the Behringer Tops or replacing those to?
 
It would help to know what model amps you have and their specs

You can buy this powered sub by harbinger. http://www.guitarcenter.com/Harbinger-HP118S-Powered-Subwoofer-105471353-i1478660.gc
You can even sell the second amp because you wont need it if you use a powered subwoofer. You use one amp for the speakers and thats it. Very simple.


To go this route you will need separate outputs from you mixer (Subout, etc) to run the Sub separately from your Tops for best performance.
 
Powered subwoofers have a built in crossover. Your mixer doesnt have to have a crossover output. When i use my qsc k12's, I use the Xlr mixer outputs to the speakers in full range. If i am going to use my Powered sub, i use the 1/4 inch booth output of the mixer to the sub. I use a 1/4 inch to Xlr Cable

A couple of years ago when i didnt have powered speakers. I used a Dbx 223 crossover to separate the highs and lows. I also notcied that my denon X900 mixer had a Sub out crossover built in. Now with powered speakers, i dont have to worry about all that. I sold everything and made it simple with just powered speakers.

Agreed! I wasn't talking about a crossover, I was talking about a separate Output from the mixer as stated. Either a subout, booth out, or aux out. Something to get two levels equal as its almost impossible to use active speakers with passive speakers on the same master output. It can be done but its not desirable and makes life very difficult.
 
Thats why the Power amp has a volume knob and the powered sub has a volume knob aswell. You raise the speakers first and then you raised the powered sub until it sound right for your ears. The speakers and the powered sub are booth connected to the mixer. Most DJ mixers dont have a sub out. Most have Xlr, Booth And Rca outs.
 
Why go through all that trouble, extra equipment, extra connections, extra worry about balancing and setup time...

Just get a pair of powered tops, two xlr connections and done, if your a mobile DJ.....

Good Luck,

Joey...

Because a pair of powered tops alone can't reproduce the full range of frequencies that are present in most types of music.

A very large % just about manage to extend to 50Hz, with maybe a 3dB drop off.

But music has got lots of frequencies below that. A bass guitar plays down to 40Hz. How many songs have bass guitar in them????

If you're not using subs, you're not hearing ALL the music - and neither are your audience!

In most cases DJs are hired to get people dancing. The BASS element of the music is what taps in to the subconscious and makes them FEEL like dancing. Even if they don't know the song. The better the bass is reproduced, the easier that happens.
