I guess I'm the next guy in line. I'm still trying it. It is in the M-line cabinet. I think that it has a little better clarity and definition than the 12 M-Line. But just a little. I have to honest in that the EA NL210 is not my favorite cab. Very warm and lush. Very Hi-Fi.But not a lot of control. For me, the envelope of the note is very important. I want a bit of "bloom" and thump on the beginning of the note. But then I want very tight control.
The reason I'm mentioning this is that I (very unscientifically) think that many of the Neo speakers that I've heard lack in the control department.
But I think EA has done a pretty magical thing with the transmission line with the M-Line. I think that there is a symbiotic relationship between the lesser control or the Neo speakers coupled with the greater control of the transmission line. The 2x8 M-line cab sounds nothing like the NL210. It is not quite as warm as the 12 M-Line, but close. And I think it has a bit better control and definition. I haven't cranked the 2x8 and 12 side by side, but I assume that they would be similar in that the radiating area is similar.
I don't know if I'm supposed to be talking about this, but I thought that I'd share my impressions. I hear that it might be a bit more expensive than the 12 M-Line.
If I hadn't played through the 12 M-Line I'd be all over the 2x8. I think it is marginally better, but only marginally so.
And a side note--
While I don't like the NL210 by itself ( tons of guys love it, though), I have to thank Mike Dimin at EA for mentioning how the NL210 and the CXL12 are an amazing combination. They perfectly compliment each other. Where the 210 is (in my opinion) overly warm and a bit bloated, the CXL12 is a bit too punchy and controlled. Driving the two with an Iamp 800 is about my favorite combination for electric bass.
