You're right... you're right.
I'm not at full tilt very often. I would say that the iNuke6000 would be adequate (all other external factors considered) to play a pair of LMS-U's at reference levels without any real notable issues... I can't hate on the product at all, because it is very good for what it is. Hope I'm not coming off that way!
But C'mon man! I get that wild hair at least two or three times a week when I just feel like a cutting loose!
I just hope they addressed the measured roll-off
of the iNuke6000 before in the iNuke 12000 is released.
Here are a few direct blurbs from the link for those too lazy to click:
The low frequency square wave (110Hz) shows gentle sloping due to the high-pass filter at sub 10Hz. You can see a slight transient at the start because this is for an 8 Ohm load. To see more detail we go to a 5kHz square wave
The same forum thread referenced 33% duty cycle testing
about half way down the first page. You know what… I'll go ahead and post this, for those too lazy to click:
Now changing to 31Hz, the NU6000 now manages 1.16kW into 8 Ohms with one or both channels driven. The traces below are for 2 channels driven and the current is now at 50A/division!
At 4 Ohms with 1 channel driven we get 2.05kW:
And at 4 Ohms both channels driven we get 1.80kW:To summarise, for music signals, both channels driven, you can expect an output of:
1.37kW into 8 Ohms, 2.05kW into 4 Ohms for full-range or mid-top duty
1.16kW into 8 Ohms, 1.80kW into 4 Ohms for Bass duty
With that said, anyone expecting to use the iNuke6000 for bass duty and expect to get the full 2,200watts will be shorted a bit.
In regards to the iNuke 12000. I would be happy with 3,600watts per channel and based on the measurements above, that seems achievable and feasible. However, the notable signal roll down at "my" favorite part of the frequency spectrum does raise minor concern (for me). But hey, they made the amp 2 ohm stable, so maybe other improvements were made as well. Someone is going to have to bench this hoss when it hits the shelves!
