AURA 2" Microwoofer Review

Given the small enclosure these need and the natural lowend rolloff, I think they'd be fine with no more than 6dB on highpass. I actually think you could get by without one atall.

 
i dunno tyr, i have mine in a really small enclosure (shared) i just used it as a mono thing for like a smal CD player (i want to build an enclosure with an amp and a battery box lol) anywho, when doing some low basslines they tend to breakup when at moderately loud volumes on the low notes, i had to EQ the crap out of the bottom end for them to sound good.

go ahead and try the 1st order 6db\oct cap crossover @ 100hz. id rather have it than nothing.

 
The driver's Fs is an octave higher (200Hz), and there's a natural rolloff already at 30dB@100Hz, so that will be pointless. I think people are having a problem because they are trying to get some midbass out of these puppies and it just doesn't have the displacement potential to do so. For use as headphones, this may be feasible, but not for normal audio use.

Granted, a filter is always a good idea, but if you can tune via the enclosure to meet the application, there may be no need for one. The less degradation and signal loss, the better.
