Today I had the opportunity to try the EA NL-210 and the Eden D210XST side by side. Both cabinets are rated at 8 ohms, 500W RMS. I played a Dingwall Afterburner 2 5-string bass. Both cabinets were powered with the same EA iAMP 500 set flat. Given the manufacturer's specifications, the EA at 100dB SPL should be noticably quieter than the Eden, rated at 103 dB. Oddly, according to my ears, the EA cabinet definitely sounded louder. In another thread I mentioned my reservations about Eden's claim that the D210XST is just as efficient at their D210XLT (both are rated at 103dB). IMO the D210XLT is quiet a bit louder than the D210XST, and now I've found a cabinet rated at only 100 dB is also louder than the XST. This of course makes me seriously question the validity of the specifications. Anyone have any thoughts on this? Further, in spite of all of the hoopla about EA "not having a sound", IMO, the NL-210 most definitely has a sonic character, and definitely does NOT sound flat. I have a set of studio monitors, and the EA does not sound at all like them. It's a very different sound to the D210XST (which isn't flat either...). I found that the NL-210 seems to be dominated by low mids and is lacking openness in the upper mids and treble, and that the highs sounds harsh when the tweeter is dialed in to compensate. As for the Eden, it sounded more open on the top due to the horn, but the horn doesn't produce a smooth high end. Still, I found it not as edgy as the NL-210. Also, the Eden sounded like it has a bit of a car subwoofer type hump in the midbass, but lacks the low mid hump of the XLT series. Words that comes to mind with the XST are "tubby", round, or full in the bass.
