NX1000D real rms specs

My google foo is failing once again. I need to decide now, I'm on vacation in 1 week and will be building 4x cx1200 subs and 3x HT-12 for a 3.1 setup. The cx1200 say rms 250 watts. I assume that the NX1000D is just a revised nu1000.

What is the real world RMS I can get from this amp if I wire my subs in series, then parallel to achieve a 4ohm load bridged on the NX1000D? I'll take a bench test of the NU1000 if anyone can find one. I would like to have 1000 watts at 10%THD, but I'll take 800 if I have to. If not, I'll step it up to a NX3000d, but if it really puts out anywhere close to 900 watts x2 @ 4 ohms I'm probably going to kill the $30 subs after a few beers.

Also, I want built in dsp for simplicity.

Output power (bridged mono): 750 watts RMS (4 ohms)

That sounds doable. Do you know off hand what the RMS of the NX3000 is @4ohm s and 8ohms? I'm also going to use the NX3000 for my mains. They claim 440 watts 2x 8 ohms, I'm hoping for at least 300 watts per channel RMS. If the real watts on the NX3000D isn't too high I might just get 2 of them to do subs and mains. A little overpowered on the subs, a little under powered on the mains.

The iNuke 3K puts out real world 5-600 watts RMS @ 4 ohm so figure half that for doubling the impedance, 250-300w at 8ohm per channel. I would skip the 1K and get the 3K or 6K (which is a better value per watt).

If you’re running 4 of those subs off of one channel wired for 4 ohm, each driver will get roughly 150 watts max, as long as that’s enough for your application. If it’s the JBL CX1200, I’ve got 6 in a BOSS platform and they can take a beating.

Speakers: PSA MTM-210T x2, MTM-210C, MT-110SR x2; Atmos-SVS Satellite x2, DIY Volt-10 x2
Subs: PSA V1801 x2, DIY: 18" RSS460HO, 15" RSS390HO x2, BOSS w/JBL CX1200 x6
MA’s: Crowson Tech x2
Processing: Denon X4200, NU6KDSP, 3KDSP

While a 3000d works, I'd get a 6000d. Easier to add the other 4 12s in a few months lol.

I would go for the 3000D personally,

Here the iNuke1000 was tested on an "amp dyno" which does 40 Hz testing to 1% distortion or burst testing to clipping. 639 watts into 4 ohms bridged at 40 Hz and 691 burst into cliipping. Although not the ultimate in accuracy, the amp dyno does give you a good idea of what amplifiers can do. If you want one of those dynos for your very own, they run around $2,000 for the thing... how dedicated are you?


The thing I find interesting is the results between certified 1% distortion and burst testing.... some amps give a little more while others give a very large increase with burst. One plate amp punched 250 watts 1% and hit over 400 watts burst which is good to know when modeling subwoofer excursion--after all, 0.1% distortion is nice but always good to know what power levels it will burst at clipping just to make sure the soft bits don't hit the hard bits.

There have been amp tests done at various loads and from what I recall, the 1000 will do a touch over 600 watts into a bridged 4 ohm load. The 3000 has almost triplle the capacity at around 600 watts each channel into 4 ohms--I'd go that direction and if you have the DSP (or D model for NX) you can turn down the limiters for protection.

Good luck!

Before the price increase, the 6000D was the best cost/performance ratio. At the current prices, I think the 3000D is the sweet spot. The 3000D is just a little more money for a lot more power than the 1000D. The 1000D may work fine for you today, but I think you will regret it in the future since it really doesn’t leave any room for expansion.

Gearclubdirect.com has a nu6000dsp for 399 w free shipping. Might be able to find a used one. Mine just sits outside my theater room, knobs are dialed in to around 50-55%. All I do is turn it on/off. I'd be very fine with picking a used one up that was used for home theater if you can find one. I'll never sell mine soon, Ebay had a 20% off coupon last year and I got it for $320, seller sold a few then noticed what was going on and jacked it up from $399 to $499. That was a great day in my life

But...but...but... it’s so ugly

Yeah that’s hard to beat at that price, plus it looks like they have a 10% coupon going.

Thanks everyone. So I'm going to get either the NX3000D or NX6000D for the subs. I'm leaning toward the NX6000D because I might get 4 more if they go on sale again. I'll get the NX3000D for the mains. Does anyone know if these amps come with the usb cable, or should I order one with it?

Edit: Looks like I can go to Gearclubdirect.com and save a couple hundred getting the old NU line instead. Is there any advantage to the NX line other than it looks way less ugly?

No significant differences between NU and NX. If you don’t mind the looks, the NU6000DSP is a great buy.

So it looks like the NU6000 can do around RMS 2000w per channel @ 4ohms. Maybe I shouldn't get that for the subs. Even if I add 4 more I'm at twice the power I need.

Unless I can wire up 4 subs per channel for an 8 ohm load. Can someone link me a diagram for that if it's possible? I can't find one.

Better to have more than enough than not enough. You can always apply a limiter.

True. I have been googling how to set a limiter on these amps and it seems confusing to me. You have to limit voltage right? Is there an easy calculation on how to set the voltage so that I get 1000w or 1200w?

No need for calculations, the Remote Connect software will handle it. Select the load and turn the control to the required wattage.

Just remember, the 6000 cant be bridged, since its already 2x 3000 bridged.

im kinda in the same situation here, my 2 subs are 900 watts rms each @ 4ohms, i researched the nx3000d only does about 4-500 rms @ 4ohms and the 6000d does about 2200 @ 4ohms, so sucks there is no sweet spot for me, except maybe bridging a 1000 but ive heard mixed stuff about bridgin amps and not sure its even safe to give them 2200 watts and under powering them sounds like a waste of money.

I run 4 off each channel @ 8ohms. You wire a pair in series to 16ohm and then wire the 2 16ohm loads in parrallel to 8 ohm. For only 4 you just use channel A. When you add 4 more you put those on channel B.

Are those brand new inukes? also i have 2 subs that are 900 watts rms you think i should get the 3000 or 6000 for 2 channel? thanks in advance

If you get the 6000D you can set a limiter as smcmillan2 says. I'm going to get the 6000D even though I don't need it. I'll run one channel with a limiter at 1000w - 1200w depending on excursion. I tend to build something every couple of years, so I'll always have 2x 2000 watts on tap @ 4 ohms.

I have my drivers, but haven't started building, yet I'm already thinking about what I'm going to replace them with...

Thanks. I'll either do this, or use the limiter that was mentioned.

Okay, so I'm going to post this and go to bed. I'm about to pull the trigger on an NU6000D and an NU3000 from www.gearclubdirect.com. I've never ordered anything from them before. I'm assuming they are selling new amps that come with manufacturer warranty and all? If so, I'll be ordering before work tomorrow.

They are new. But I dont know about behringers warranty. I haven't had any issues with mine so I've never worried about it. I can look through my boxes and see if I can find that info

I got in on that deal as well, but I guess lady luck was shining on me that day because I received two (2) 6000DSPs instead of only one.

Looks like behringers warranty is 3 years. That's nice if they actually replace broken stuff. I haven't bought a pro amp in a while, probably 6 years. I don't remember what kind of connections you need to go from the pre outs of the avr to the behringer, than from the behringer to the speaker wires. I think I need xlr to rca to go from the avr to behringer. What goes from the behringer to the speakers?

2 50 cent 1/4 to rca adaptors and 2 speakon connections....I picked up a 100ft shielded rca cable from parts Express for my sub cable, one finally broke after getting shut in a door but for $10-15$ it's not bad.

Ok, I have the speakon thing down, but I'm confused about the xlr connections.

For the mains (nu3000):

I assume a red and white rca goes from the AVR preout of left/front channel, to one xlr connection that goes to the inuke A channel. Same for right/front except it goes to the B channel.

For the subwoofers (nu6000dsp):

I'll be driving all 4 subs from the A channel @ 4 ohms. So does a single RCA connection go from the AVR subwoofer preout to a single xlr connection on channel A of the nu6000dsp? I can't remember how I did this 6 years ago lol.
