Wow, is the ep800 big. like wow. But here's the thing. This is the in-cabinet version and it has 4, yes, 4 sets of binding posts. And there are 4 on the amp they sent. Do I really need to hook up 4 pair of speaker wires to it? I hope not. I only ran one in the theater for it and the walls are already up. Anyone from Axiom or that has experience with big ass subs, please help!

Yes they all need to be hooked up and they must be done properly. Please read the manual carefully or call Brent for assistance.

There's an in-cab EP800?

There is an in cabinet 800. I'll post some pics at some point. I won't have my new room dones for 6-8 weeks, but I may try and put it into service in my family room tonight.

Brent called. there is indeed 4 seperate amps in the amplifier Axiom provided which requires 4 sets of speaker wire to be connected. Although none are labeled so I took for granted it didn't matter which would go to which. Are you saying Steve each set will only go to a pre determined set of posts?

Also, it's too new. No manual as of yet.

Whoa.

Pics, please!

I must be missing something - won't you simply be connecting a sub cable (RCA or XLR) to the line in on the back of the sub? Are you specifically planning to use the speaker level inputs?

I just looked at the manual for the EP800 online and it must be out of date as it does not show 4 sets of binding posts.

I'm guessing that the in-wall version has a separate amp box that goes outside the wall.

each pair of amps should go to the same speaker. each amp powers 1 set of voice coils per speaker (each speaker as 2 sets of voice coils). i would say, theoretically since you are using 1 signal, all amp channels will have the same input-> same output, so it "should not" matter what you hook up to what, as long as you get the polarities correct + to + and - to -...


Are the binding posts labeled in any way?

Nope. Nothing is labeled so I think your right. It sounds and feels great.

cb919. The in cab has a seperate amplifier. The sub cable runs to it and four pair of speaker wires run to the sub.

So my 800 has a 60hz hum. Upon taking out the ground loop screw, the hum is gone. Great. My question is what is this screw's purpose that I can just simply take it out without causing any issues.

unscrew it 3 turns, and leave it in. if you plan on never moving you can take it out, but simply unscrewing it will break the ground connection and will be sufficient. I had to do the same with my EP600

Doesn't seem like a design I would be interested in, especially if you have to run that many cables/wires to one location.

BW, the purpose of that screw is to connect the chassis of the sub amplifier to the shield of the sub cable. Ordinarily this might allow for a slight further reduction in overall noise level. However, if a ground loop is present, the resulting hum fed into the sub cable overwhelms any other factor. Removing the screw still leaves the sub amp grounded through the three prong wall plug, but cuts the loop which could exist through the sub cable.

Sirquack, I see your point. But when looking at something that can become part of the wall, pulling out 110lbs everytime I want to make an adjustment seems alot harder than running 4 wires one time. Not to mention, the sound overrides everything and this baby can get low.

Thanks, makes sense now. That's actually a pretty cool design for flexibility of tweaking after installation of the beast - way to go Axiom!

The ironic thing for me is that even though I had to do an on-wall setup for my mains, one of my optimal sub positions is in the back corner behind my couch and I could easily fit an upright EP800 there!

Has anybody blended an EP800 with M22's in-on walls?
Not that my wife would go for it today, but there's always tomorrow!

That one was really well answered John.
I hadn't really thought about that before, but it makes sense.
Now if i only bother to remember that to explain it to someone else.

I was going to say that but John beat me to it (I was busy trying to tie my shoes). I should really get my priorities straight.

You're a funny man Cam!
