I'm going to build my first set of speakers, a pair of Dayton Ultimax 12" with Parts Express knockdown cabinets for my living room. I'm going to power the pair with a inuke 3000 dsp amp. I'm building my shopping list right now and have a few questions.

 

 

1) I have a Denon AVR that will feed the amp via RCA. How do I hook up the amp? (RCA ---> XLR) or (RCA ----> Y-splitter ----> two XLR's)

 

2) When connecting the amp to the subs, do I just connect them with a speakon cable? Do I need the 2 pole or 4 pole connectors?

 

 

Thanks, I'm sure I'll have more questions as the project progresses.

I'm not real familiar with the inuke but I think it has a biamp mode where you can input with one signal and output two so you wouldn't need a splitter. If you're doing stereo subs then 2 pole is fine. 4 pole is needed when you bridge the amp.

Thanks, searching for inuke biamp connections turned up a picture that was much more helpful than reading the manual.

Most of my stuff has came in. I started gluing the flatpacks together with Titebond 2 and clamps. Do I need to seal the cabinets? If so, with what?


Thanks

If you properly glued the cabinet, there won't be any leaks.

missed your post the first time through.


the inuke needs a splitter before the amp.


in other words, you must have a separate input for each channel going into the amp if running one sub off of each channel.

Thanks LTD. Any benefit form spitting the RCA or the XLR? Or just get what's cheapest?


Code:
RCA ---> RCA ---> XLR ---> AMP
     \--> RCA ---> XLR ---> AMP


      OR

RCA ---> XLR ---> XLR ---> AMP
             \--- XLR ----> AMP



This represents a splitter:

Can you use the inuke itself as a splitter, taking channel A input and run it mono to both A/B outputs?

Anthony, I've been trying to figure this out. I've read yes and no on the forums and the instruction manual is not clear (to me).


I'm still a little green when it comes to terminology. I've been reading until my eyes bleed but somethings are still muddy in my head.


EDIT:

Here's the manual if anyone wants to take a peek:

Here are some pictures so far. The cabinets are very easy to build. I have very little wood work experience and these were fun to build. I still have to install the front piece and attach the baffle. I also decided on the green faux leather for the cabinet with a black painted from.

EDIT:


I need to get the real camera out, these cell phone pics kinda stink.... sorry!

not in the way that most folks want to use it.


a splitter is required to send an input into each channel.

I stuffed both boxes with a pound of Polyfill each. I'm going to add a screen to keep it out of the driver. Probably the only thing I'll get done this weekend... Stupid homework... Hopefully tomorrow I can cut and router the countersink holes for the speakon connectors.

I would line the walls with thick insulation or polyfill if you can. The driver has a high qtc in that size enclosure according to winisd so a heavy fill can bring that down a bit.

I added another half pound to each box, so total of 1.5 pounds per box.




I'm going to make a RCA to XLR splitter cable. I heard I should use microphone cable (whatever that is). Can I use 12 gauge speaker wire instead? Also how should I wire it up? I'm new to XLR plugs but I can solder like a champ.

Is diagram 1 possible without the shield? If not I think I'll try to make them like diagram 3 if possible. I was going to order these:

I got this RCA to XLR madness straighten out!

I got the faux gator leather on one box. Used Loctite 200 spray adhesive and staple gunned the bottom. I also installed some little black plastic feet I picked up at Home Depot for $2.50. I bought some rustoleum bed liner for the front baffle (that's primer on there now).


I purchased the gator material at Big Z fabric for those that are interested.

Can you take a pic at a lower angle and a bit closer ? It looks good and want to see better. My wife might like this.

Baffles are almost done being painted.


I have a question about installing the driver. How or what is the best way to drop in the driver into the cabinet without scratching the baffle?

Loop a few zip ties in the driver mounting holes for some handles. Kite string would probably work too.

Good idea. I didn't even think about looping something through, dropping the driver in and cutting the loop so it can be removed. The joys of doing something for the first time and all the strange questions that arise.
