I have read a LOT of threads about the iNukes and may have missed something, but I cannot find a definitive answer as to the roll off of them. I am debating the NU3000DSP or another EP4000 for my buttkickers. Obviously I want the least amount of roll off and know the EP4000 has been measured to 5hz. The iNuke is so appealing, with its light weight and DSP (not so much for the buttkickers but may be useful in the future). Any info I am missing or opinions on one versus the other?

Thanks,
Bricktop

My 3000 dsp is good down to 16 hz which is my port tuning . Below that I don't know .

Ep4000 is 5hz.
Inuke is maybe 2-3 db @ 10hz

Both would be good for about 99% of people.

LTD posted the chart in another thread, see if I can find it..

So it is down at 10hz. I think for a transducer the ep4000 looks better.

here is the image again, so that it can be expanded on screen.

it is down about 2db at 10hz, which is roughly consistent with a first order highpass filter having a -3db point at 8hz.

if 3db at 8hz is deemed important, a shelf filter could be applied to bring it back up by 3db for "flat to 8hz".


Listen. It's All Good.

^^^ That being the case, my concern is more directed at the noise level of the fans between the two of them. One (i) is loud and one (E) is not as loud.

Having a response down -2dB at 10Hz is different from being capable of delivering full power at 10Hz, right?

I was under the understanding that the iNukes DSP could not apply a filter below 20 Hz, so it would have have a center frequency at 20. You could boost it with an mini DSP, but that defeats having an nu3000dsp. Still looks like a good amp, but with single digits being important for a tactile transducer, it seems to have a weakness in that respect. Decisions, decisions.

The 3000 dsp can go lower then 20 hz with a workaround . As for single digit hz being important that would be for a single digit percentage crowd. If its important for you then you will need one of the pros here to answer that.
