Yet another dual opposed mfw 15 build (my first ever) - Page 4

Thanks for all the compliments, it truly does mean a lot. I really owe it all to this forum, it was this place that even got me thinking diy..

About the binding post question, the answer would be, uh idl? lol
I bought a speaker terminal plate from parts express very similar to this.

So they are kinda binding posts, but they are mounted to a plate, so I am going to go with your call on that.

Have a good one...

For those with an ep4000, would you get better results splitting the input signal and feeding both inputs and running the amp in stereo, or just running to one input and setting the jumper to parrellel?

and about those jumpers, I don't want the amp to add any kind of filter, I just want to amplify the signal my AVR sends. so what would I set them to?

thanks for the help.

I don't think that I and having a problem driving the amp to capacity. When I put some BASS heavy music on and approach reference, I have no problem driving the amp to clipping. So I know that I have the voltage even when running through an RCA Y adapter.

My question was more about SQ, would there be a difference?

And would the extra connections inline with the y adapter introduced any more noise?

The jumper setting are confusing the hell out of me. I think I have it right, but there are articals on here and "the shack" that state that the silk screen in the back of the amp is incorrect.

So to those that have a set up similar, how do you have things set?

So I should buy a new RCA cable? I am using an old RCA that I have had for awhile that I bought for my old place in which I had the sub on the other side of the room. So the cable is 25 ft I think, but I need less than 10ft now...

I do have a major hum issue, that I made much better (but still audible). By running a wire from chassis ground on my onkyo.



To the shield side of my RCA before it runs into the y adapter.



This made a HUGE difference, but it's still annoying at low volumes. what else can I do?

BFD? nope. all I can think of there is nothing to do with audio, and all the reason I just had a son.

I think I figured it out...

B.F.D= beringher feedback destroyer. Yay! now were is my cookie...

To answer the question, no, I do not. I have a mini dsp, but that is neither configured, not implemented, as I require capital for the necessary SPL meter and connections....

No worries mate, It's all good. Anyone got any other ideas?

No offense taking man, I actually ditched it a couple of hours ago. It's in the garbage along with my old RCA cable. I just figured I could buy a new cable and try it out, if it didn't help with the hum issue, I could always return it.

But when I plugged the new cable in, my hum, was GONE unless I turn the gains up on my ep4000 all the way.

So for me, a new shielded RCA fixed my problem.

Thank you very much for your kind words. I am already thinking of future projects....

Going to see a build thread about those tempests?

Maybe, but until I get the mini dsp in line, I am content with the cabling for now.

But as to what I am going to do once I try and get that thing working, I am not sure...

Should I just cut my brand new cable right in half, and wire to the Phoenix connection that way? Is the inside of an RCA cable coded in some way to insure proper polarity?

Uber nervous about that.....

No, I have not done the fan mod, I honestly don't know if I am going to. Right now the ep is about 15 ft from lp, and about 4 ft above ear level.. So the fan, doesn't bother me yet. (I may change my mind once the weather cools and we don't have fans running almost all day)

As far as the sound goes, what can I say that has not bin said?

I came from a single cerwin vega lw15, so pretty much anything would be a step up. These are a Ten story jump up. But they are a completely different animal.

The cerwin used to rattle the ceiling panels in the adjoining kitchen something fierce, to the point where I heard that more than the bass. It was a ported sub, that had typical tubby, muddy, undefined,sound. I bought it cause it was the most expensive sub they had at the store in the little sh%t hole town I was living in.

To compare that to these, well there really is no comparison. That would be like a head to head on a road course between a dump truck and a corvette. Sure, the dump truck will cross the line, but not nearly with the finesse and beauty of the corvette.

The 2 dual opposed cabinets, have a much more even room response, than anything I have ever experienced before.

At first, for music the sound made me feel that maybe I had done something wrong, but after some tweaks raising the output level from the avr, and running auddasy, I was astounded by the level of detail, the speed of the transiants, and the overall depth of the sound.

Then the kids and I watched Rango, and the impact of some of those scenes surly put a smile on my face. The next night, hungry for more I rented the last Narnia movie, and again was like a kid once more. The scene where they are in the boat, during a thunderstorm, I thought maybe it was real, I actually paused it to see if I had to run around the house closing windows.

I mentioned earlier that my old sub used to shake things in my house, the new set up, shakes the inside of me. I feel the visceral impact of explosions, the thunder radiates in my guts.

There really is no words to explain how happy I am with these 2 cabinets, and this is before I get the mini dsp online with this setup. I truly cannot wait for that day.

Oh yeah? Lfe a plenty in battlefield?

Got to pick a good one for adult movie night.. Any other suggestions?
