Hi every!, Hope you can answer my interrogation I recently purchased that.


http://www.edesignaudio.com/product_...roducts_id=849

which is

http://www.edesignaudio.com/product_...roducts_id=891

I built the whole thing and it doesnt seem to play at normal level, i use the behringer 4000 amp. I used 16 gauge normal speaker wire to wire everything up, is it the problem? do i need stronger wire? what is max watt a 16 gauge speaker wire can handle?

inside sub the wire are all 16 gauge speaker wire hook like this plan :

http://www.edesignaudio.com/wiring/2...esparallel.jpg

From the sub, it is speaker wire 16 gauge to the amp. The amp get signal from my receiver using a RCA to XLR wire ( pre out from receiver to the Imput 1 In from amp)

The speaker wire used are these:

Do you use special wire when you make your own subs?


P.S : i know the woofer are ok since i can hear TV when plugging directly from my receiver using left tower outs ( at very very very low volume, like if there isnt enough power to drive them, my receiver is 100 wpc) Also, if i turn the gain to max on my behringer the Distortion light up, I think wire cant carry the power, am i allright?

16 ga is fine. Use this calculator to determine gauge requirement:

You may have something wrong with your amp connection, not unusual when you mix consumer and professional gear.

Are those dual 2 or dual 4ohm drivers?

You may need to get a rca/xlr active converter to boost the signal. One such device is the mic2200 from Behringer

they are both 2ohm and 4 ohm depending

There was a 4ohm sticker on mines, so i assume they are 4ohm. If i understand you, i need something between my receiver preout and amp to boost the signal?

They should be wired in series/parallel to get a 4ohm load.

I'm not an expert in pro amps and receivers but if the volume is not loud enough then you probably need a booster.

That's a lot of coils to wire, and a single error would severely compromise the result.

Yes exactly, you can see how they are wired in the first post.they are in series/parallel. I think the signal needs to be 2-3 times stronger. Right now if i crank up the Behringer at max and play movie at -40 or -50 below reference lvl i can her the sub from the sofa, but it plays way less noise than my towers, and Xovered at 150...

Also i tried to wire RCA to 1/4 and RCA to XLR. With the 1/4 i get no sound at all... with the XLR i get sound. It's something in the wire signal, hope i'll find out with all your help

What you mean by boosting signal. I can plug my RCA on the input, boost signal with the output DB and the signal out will be XLR balanced?
