Beldin mic cable??

Oh, oops. I thought you were making an RCA to XLR cable with speaker wire. Don't mind me...

Matt,
your cable shipped out, but just barely(~2 minutes before close).



I've made cables from Dayton Mic cables before. You get a free connector or two and it's quite flexible, but the conductors are very fine strands.
So for install stuff I use the Dayton MLI, it has PE dielectric a foil & mylar shield all the conductors are tinned for easier soldering. I think it's a bit easier to work with.

Thanks so much Dan!
Picked up an rca cable, speaker wire, speaker terminal, titebond and gorilla glue, and nails and screws.
I also tipped the guy at my Lowes $10 and he made all the cuts for me except for the driver holes ofcourse.
So I'll be ready to go once the Tempest-X arrives on tues./wed.

Dan,
Got it today....sexy cable, very nicely done.
Completely pro looking.
Your the man.
Thanks again!!

Hired a cabinet maker to put my box together.
Since I ahve all the supplis he is opnbly charging me shop time-$40 an hour. Shouldn't take more than two I'm guessing.

Just need to find out what size holes for the two front baffles and the inner brace for my Tempeast-X??

So I got the box home and he did a fantastic job, but he did not router the front panel of the double front. Can I just mount the driver on theoutside surface....or should I rent a router?(temporary box)

O.k. ... got it all ready to go except for the dip switches.
I can't seem to figure out which ones to move.
Running one channel to a dual 8ohm Tempest-X??
*Also, how do I wire it from amp to binding post '&' how do I wire it from post inside to sub?
post #39 of 123
On page 5 in your driver's manual it shows how to wire the speaker for a 4 ohm load....

I did not receive a manual with my Tempest-X from Kevin.
Also, his site is down.

Its in the link I posted. The DIYCable.com site works fine for me, if thats the site your talking about.

No, I see that and thank you...I was just explaining why I had to ask.
Thanks again!

Why don't you wire the coils in parallel for a 4 ohm load and bridge the amp? I thought the EP2500 amps could take 2 ohms per channel.
post #44 of 123
Thread Starter 
I don't even know what that means afraid to say.
The way I just did it now is to the two posts on the sub from the binging plate/posts, then single wires from the + to the opposite sides +post and the - to the opposite sides -post....what is this considered?
post #45 of 123
Im not sure what he talking about neither. You do have your sub wired in parallel for a 4 ohm load, but why would you want to bridge the amp to send 2400w to a single Tempest-X?? And what does the amp being able to do 2 ohms per channel have anything to do with bridging the amp for a 4ohm load? Maybe he thinks you have 2 drivers, but even then.

Dont worry about it. You have it set up the best way for the equipment your using.
post #46 of 123
As he is in the testing phase, running sine sweeps and test tones having 2kW on tap is excessive. One channel of the EP2500 should get the job done, it also happens that he will most likely be running the amp at 4Ω stereo with dual subs in it's final configuration anyway.

O.k., got it al wired up and plugged in......
No signal to sub?
Everything turns on and goes green, "except" for the signal light on the amp?
I tried to run audyssey but still no signal to the sub.(but the SW icon is lit up on the AVR)
post #48 of 123
Wheres the gain at on the amp? Are you sure that you have your signal cable pluged in the input 1 channel and speaker wire is connected to the output 1 channel?

Another thing to check, Make sure that you have the signal cable pluged into the sub pre out and not the sub input on the back of the receiver. I know it sounds obvious, but I have made that mistake before.
post #49 of 123
did going direct work?

try plugging into the RCA out from a main R or L channel to see if feeding the amp a signal you know exists will get it some sound out of the amp

Wow at the crazy prices these are going for in the UK and for 1.2kw that’s a nice bit of headroom, I might consider one of these for the JBL 4645, might because I’ve got in mind the Alesis RA500 in the not too distant future and that will only give me tiny amount, not that I need it I’m running a Alesis RA300 in bridge mode right now and that is moderate improvement over (none-bridge-mode).

Might consider because I like to keep all the new amplifiers too the same brand and model for most channels and different for other channels, might consider!

All the thanks in the world to all of you for helping this dult...but especially Dan!

Just getting it going and taking it easy till I really get a grasp on things, but.................



Oh and guys, I had the loudest most aweful hum until I grounded the RCA to XLR cable that Dan built me to my AVR(didn't know what that extra danngling wire was until Dan told me, lol)......now none 'at all'.


As soon as I can learn REW I'll get graphs up, but that might take afew days as it is tough to learn for me.


THANKS DAN!!!!!!

So, why were you not getting a signal to the amp??

didn't you see all the smiley's?
She's running awesome now!
I had the switches exactly opposite of what they were supposed to be.
I also, in fear, had the gain at only 25% and it wont show a signal and work until I get loud enough on the AVR volume dial or what I did and raise teh gain on the amp.

I'll get pics up of my whole set-up when I get completely finished with this project.

I just got the EP2500 and wanted to fire it up before my other subs are built.

I have 2 ED subwoofers each wired at 8 Ohms.

I purchased one 1/4" to double RCA converter and I have that plugged into Input 1.


I set my dip switches just like the above picture shows. Except I had 4 and 5 switched to parallel inputs, which I assume is correct.


I have a Denon 987 and I'm using the LFE line out. I turned the sub level to max.


I have the gains all the way up on the EP2500, but it takes me turning the Denon volume up to about -12 before I start to see the signal lights on the amp flicker. They aren't steady burning at that point, and even turning the volume up really high doesn't get a solid glow from the signal LED's. Subs aren't getting much power, but mains are obviously loud.


Any suggestions?


Thanks.

Make sure your 1/4 inch to double RCA converter has a mono phone plug not stereo.In other words a two conductor plug, not three conductor.
post #56 of 123
That might be it. I wrote down what I needed (XLR to RCA). And went up to Radioshoack because they are so close. He didn't have the XLR to RCA and but said "This will definitely work."

But I am almost 100% positive it is the stereo 1/4".


So do you think that would definitely be the issue? I haven't found any info that says the Denon signal is too weak for this amp.



I'll go to Guitar Center tomorrow and get the right one.

Thanks.

The Denon will have enough of an output signal to drive the EP2500 , I use one myself. Post a photo of your 1/4 plug so we can tell if its a stereo or mono plug.

I'm glad to hear that.

This is exactly what I got, and it does say "stereo" in the description.




I had a feeling about that too, but the salesman assured me I needed that one. I should have known.

Thanks.
post #59 of 123
yep ,thats a stereo plug. A mono will have only one ring at the tip . Got to love salesmen who dont know what they are selling.
post #60 of 123
If you are using the LFE output from the Denon I don't see why you need two RCA jacks. A simple RCA phono jack to 1/4 inch phone plug adaptor should be all you need.
