I am in the process of DIY. What I was wondering is how to connect the sub driver to the Amplifier if the Sub has a "positive and negative" connectors; the terminals also is "positive and negative" but the Power Amplifier (ie. BehrinhgerEP4000) has XLR/Phono Plugs?.

you sound like you are talking about a home theater in a box type setup where the signal out of the main unit is amplified and sent to a passive subwoofer. i'm not sure how you could add an ep4000 and subwoofer to that setup.

Thats why Im asking. Many people here use Power Amplifier on the DIY Subwoofer Enclosures for Home Theater. I tried to find more info on this on the web without luck. All info I found was as for full-range speakers, or with mixers; etc; but not as HT.

You need an RCA to XLR cable from monoprice and some 12 guage speaker wire. I prefer inwall but it doesn't matter. The amp also has positive and negative terminals on it.

mpray, the problem may be that he doesn't even have rca outputs to begin with.


if there are no rca outputs, then the signal is being amplified out of the main unit right now. i'm not sure how to get an ep4000 into use with that setup.


one option is to find a plate amplifier that has "high level inputs" (these are speaker level inputs like you are probably using now).

You connect the sub driver to the black and red binding posts on the amp -- NOT to the XLR plugs. This is what the EP4000 looks like -- you will connect the sub to the "Binding Post Terminals":

You will also need to connect the line-level signal to the XLR or TRS inputs on the EP4000. What do you need to connect to? A home theater receiver? Something else? Tell us the make and model so we can look for information and pictures.

I think he has an LFE output...but he just didnt know about the pos and neg terminals on the back of the ep4k because he probably saw a picture of it with the cover on it.

one sure way to find out.


javygonx, does the back of your receiver have a LINE level or SPEAKER level output to your subwoofer?

The suspense is killing me...

 

[Audiophile34]

It's actually quite simple...


speaker out into

http://www.amazon.com/Xovision-ANF-2...ata/B00474X1FG


which converts speaker out into RCA's (adjustable for level)


then you just buy

http://www.amazon.com/s/ref=nb_sb_no...+xlr&x=14&y=17


which takes your newly converted RCA and turns it into XLR.


elementary my dear Watson... lol..

 

[Mpray1983]

I'm still going with he has an lfe out. I am prepared to eat my words though.

Binding post terminals (as pictured). + to + , - to - .


Just make sure the hole through which the wires enter the enclosure are air tight.

Or use binding post terminals or Speakon (4 pole) connectors (this connection would mean a special cable from amp to sub.)

nice pull audiophile. never new such existed. not that it applies here, but that is a nice one to know exists for all other htib folks.

Thanks Max for the info, and yes, this is going to be connected on the Subwoofer Pre-Out of my AVR Receiver. Is a Denon 3311CI. And yes Mpray; I didn't knew about the pos/neg terminals on the back of the EP4K. Thanks to all


Anything else I should have to know about it before connecting anything?

 

[Audiophile34]

Thanks, I used to use the speaker level to RCA all the time in car audio hook ups..


easiest way that I know of to hook up an amp to factory radio. (just pull signal off the rear speakers)


The RCA to xlr I picked up at a local musician supply store, I told him what I needed, and he gave me that...

 

[Audiophile34]

Well then, pass the crow, lol...

 

[Mpray1983]

I knew it...Flip low cut filter to off and you should be good to go.
