Is it possible to run 2 boxes, 4 drivers with the LG? Or is it to much power at that point.

You could wire the two drivers in each box in series for an 8ohm load per channel on the 14K. I believe Gorilla was doing this when he had two dual opposed boxes.

Sure, just run it in 8 ohm stereo, no problem there.

It depends but you should be fine either way.

The RSS460HO-4 18" is back in stock at PE for anyone who was waiting for them.

Cleaning it up getting ready for paint. Probably time to start cutting box #2!

Looking good, my man! cool.gif

Is it fine to use cabinet plywood from Home Depot? I was thinking of using it for the next sub. A little easier to work with than MDF. Here is a picture of the edges. I thought that dual opposed and a couple of braces made it alright to use.

It has a thin outer veneer, and probably cheap glue. The trouble is that veneer can delaminate unless you use screws as well as adhesive to fasten all the joints. For the most part big boxes don't sell good plywood, they sell cheap plywood. The Arauco brand is the only one I've found there that's acceptable. It has equal thickness plies, no thin veneer, and uses high quality glue.

With that being said, Bill, where is a good place to pickup good plywood? Any of the chain or speciality stores in the south that you might recommend? We have a Bartens and Lowes and Home Depot here in Arkansas, all are fairly close by.

Look in the Yellow Pages for custom kitchen cabinet builders, find out where they get their plywood.

How far from the back wall does this sealed version of the sub need to be? Can it be like 2" or does it not really matter. The reason I ask is I am trying to determine how fare away from the rear wall my AT screen will be. I am assuming I should leave about 4" between the sub and screen.

That's tough to say. A lot depends on the room and how placement will affect FR at the LP. Mine is a sealed forward firing design and is sitting about an inch from the back wall. DO opposed will make a bigger difference. 4" is fine as far as placement from the screen. That's about exactly how far behind the AT screen mine are placed.

X2 - You really will need to measure to see if there is any significant difference between distances. Mechanically, you only need about an inch or two to keep the driver from hitting the wall, but I think allowing for 4-6" or so is pretty common.

Good to know I might need to expand the room by a foot. 24'feet long instead of 23' then. Modeled it in sketchup and placed the JTR tripple 12's on top.

Sweet looking room. smile.gif
Should make for one very nice HT experience.

Would a Inuke 3000 be suitable for this build, or should I upgrade to the 6000? Its a little unclear to me how you guys wired them up. Other than that I'm totally copying gorillas build!
I not sure if I should apologize for that but I sure would like to say thanks!

How many drivers are you running? The 6K isn't 2 ohm stable so configuration wise it's not the best fit for a pair or quad drivers.

I'm trying to pick an amp for these also(2 DO build/4 drivers). The 2 that I'm currently considering are the CV-5000 and LG Clone. If I could find any real world data on the CV-5000 I'd go with it. Surely someone here has one. I did see the Peavey CS4000/4080 too.

The Crown XLS5000 is pretty much out. I can only find them in stock for $1k and up.

What else is there in this price/output range?

The CV5000 is quite popular on here - Mr. Smithers is running one which was sold recently to Carp. That amp will properly power a quad set of these drivers with ease. The EP4000 or inuke3000 could also be used, albeit with a bit less power.
post #861 of 1005
Any idea how low it gets before it starts to roll off? Also would you care to compare the LG clone to your Crown running the 2 pairs?

I'm skipping the EP4000 and similar. I don't want to be upgrading next week. Now buying another and more drivers is a different story.

Can't say for sure about roll off, but my Crown appears to be solid down to 7hz or so.

The clone running in 8 ohm stereo driving a pair sounded nearly identical to the Crown running in 2 ohm stereo driving the pair if that helps.

BTW my clone amp is down for repair at the moment. I'm going to be powering all 4 pairs shortly with the Crown. Looking forward to see how it sounds. smile.gif

Here is a link to a comparison Carp and Mr. Smithers did vs. the Submersive using the CV5000 to power the daytons.

+1. I have one of my CV5000 running the Daytons in my temp setup right now. One CV powers 4 18s to some really good levels. I haven't measured it at the lp, but can. The CV is a steal at the price imho, an easy choice for good reliable power. GC usually has a coupon going and you can get them for 699

I'm building one dual opposed box. I own a Inuke 3000, my wife gave it to me for Christmas specifically for the build.
Where I'm confused is in the specs, may have jumped the gun on making my wish list...

Inuke 3000...
* Delivers 2 x 1500 Watts into 2 Ohms; 2 x 880 Watts into 4 Ohms; 3000 Watts into 4 Ohms (bridge mode)

If I ran at 2 ohms I would only be running one side of the amp, basically dividing the 1500 from one channel into 750w to each driver? Is that right? But could run a future dual opposed off the other channel?
Running 4 ohms from both sides of amp I would get a few more watts to each driver? Finally, the bridge feature is no good in my case?

Inuke 6000...
* Delivers 2 x 3000 Watts into 4 Ohms, 2 x 1500 Watts into 8 Ohms
I would have 3000 for each driver, and be running both sides of the amp? Albeit seems overkill smile.gif
Vs running 8 ohm I would essential be running 750 to each driver but could run another dual opposed.
Do I have that right? The store that sold the amp said i could exchange, so i have a out. Please advise lol

My room is 20x11x8 and this is my first sub diy, I plan on dropping these behind my screen and then 2 more singles on each side at the back of my room.

Hey - If you've already got the Inuke3000, might as well rock that for now. You can run both subs on one channel or even one sub on each channel. If you move to two dual opposed subs, you can just run 2 per channel. It will do a pretty decent job of driving them too! If you're going to upgrade though, don't move to the 6000, go to something like the cv5000.
post #866 of 1005
Well that's exactly what I'm going to do. Thank you

I would have to agree, I ran 4 off my ep4000 for a sec and they sounded good, I could just tell that I might run into clipping for the more demanding movies. I think you will be fine with the iNuke for a while, just upgrade as needed biggrin.gif
post #868 of 1005
mrsmithers has a CV-5000. It's the real deal. The two fans are a bit loud - figure on replacing them with a quieter set. He ran a pair of Dayton HO 18" drivers for what their worth with one channel of the CV-5000. He could probably be encouraged to provide details through PM, or maybe post here as well.
post #869 of 1005
You can use two inukes for the price of one cv5000. So, the price per watt is not different in either case, that is unless you are limited to one amp for some reason.

In dual opposed? That would be either 2 or 8 ohms? I somehow don't think an inuke in 8 ohm mono is the same as a CV5000 on 1 channel of 2 ohm stereo. I've been wrong before though.

I'm gonna order a cv5000 and give it a whirl, if I'm not satisfied, I'll go bigger or order another set.

Out of curiousity what would be next besides a clone in this power class for 2 DO Daytons?
