Sprite now available in 4 and 8 Ohms

It's taken me a long, long time, but I finally got around to working up a filter for the 4 Ohm version of the ND90, as a counterpart to the 8 Ohm version of the original. But which is better? From the updated Sprite page...

Well, the 8 Ohm woofer only needs 2 parts, where the 4 Ohm needs 3. Still, the cost difference is probably pocket change.

On the other hand, the 4 Ohm woofer is more efficient--almost to a fault. It goes LOUD, like "I can't hear myself think" loud; but past about halfway on the dial, and you become intimately aware of what Intermodulation Distortion is. But what do you expect when you are asking a driver to not only play bass down into the 40 Hz range (with 4 mm of xmax!), and simultaneously play treble up past 16,000 Hz? So horses for courses, I guess. For most practical applications, especially in smaller rooms, I'd use the 8 Ohm version. But if your application involves larger rooms or crowds of people and you want them to shut the hell up and listen to the music, then the 4 Ohm would do you right.
