i looked for more info on this but could not find it. anyone have advice on which would be better? ill be driving 4 SI 18's. dual 4ohm VC. basically 2 per cab making a 4ohm total load.

one bridged EP4K for each par or run both DO boxes off a single iNuke6000DSP?

Inuke saves me money but im concerned about performance/reliability.

I am a big fan of the DSP feature in inukes. AFAIK, 2000W @ 4 ohm is realistic number with NU6000 version. I have not heard of any reliability issues .

hey great. a tie!

the DSP in the iNuke is what interests me as well. i wouldnt need to buy a Minidsp which saves more money. tets of the 3000 seem to compare with the ep4k and the 6000 is just two 3's bridged sooooo. Like i said, im just worried about the quality and ULF performance of the iNuke compared to the EP4K

i didnt see that one, so it looks like the 6000 is the better choice for my application?

The way I understood it, the amp is fairly flat to 10hz. However continues output with low impendance load at 10Hz is not guaranteed.

I own (and have measured) a 3000DSP.

It delivers the power I need, but the DSP is not usable below 20 Hz.

Not a bad amp at all, but it would be more useful to me if the DSP software matched the 10 Hz capability of the MiniDSP.

For use as a home-theater sub amp with highpass above 20 Hz? Should work fine. I just need a lower limit on the DSP.

You can combine HPF and PEQ around 20Hz to simulate sub-20Hz HPF.

I never had to EQ below 20hz. Normally you'd do a shelving filter or LT to shape the signal in the lower octaves, but the filter itself is set above 20Hz.

I might just go with two ep4k's and a minidsp. Ill have more options, flexibility, redundancy, and proven reliability.

I remember reading recently about minidsp being limited in output voltage to work well for sub EQ.

I was reading that as well. Has me concerned. That's the other plus of using the inuke. If there is a input signal issue I can just buy a bump box. Problem solved. But then again, the inuke rolls off at 10Hz. The ep at 5Hz. Argh. So many choices.

Depends on room, placement, etc. No way to know without trying.

Most newer AVR's put out plenty of voltage to drive pro amps. The mini dsp can be purchased in two different versions which will fit most all installations.

Bottom line is the EP4000's can be had for a song and dance, put out a true 1900+ watts at 4 ohms, and don't roll off signal till well below where room gain occurs. I'd personally go that route.

I don't have an opinion about which one would be better for your setup, but here's some additional info to consider...

The shallow, super-light NU6000DSP is much easier to lug around, and may also be easier to fit in a rack if you have rack space issues.

The iNuke is also easier to fan mod, and would likely be quieter overall, since you'd only need a single 12v (common) fan.

People are reporting additional discounts at amazon for the iNukes in my fan mod thread:

Thanks Max. The 6000 gets a $75 discount right now. That is another reason I was looking at it.

The weight and noise is not a problem for me. It will technically be on a shelf in another room. Backside of my built in av rack is only open to the adjacent utility room.
