from Good entry level planardetailed to around 18000, but at the very top it isn't the most detailed driver that I've heard. It does do nicely still, and has a good range. Build quality is good. The front plate looks very nice, and is quite solid. It has a high sensitivity, so that is something to keep in mind while choosing a complimenting driver, and designing a crossover.

from musical shimmering highsUsing a third order filter at 4.25khz doesn't overstretch it's performance envelope and the listener is rewarded with an airy dynamic and tuneful rendering of music's essential harmonics. I found a notch filter at @ 11khz was also needed to remove a tinselly feathery type colouration, leaving behind only a slight 'plasticky' tinge easily forgotten with such a musical spacious performance.

from Pristine treble, and great imaging and dispersion.I used this planar tweeter with the Dynavox LW5004PMR in a stand-mounted design (Vijon). This planar likes steep slopes, and I think about 2.8 kHz 4th order is its minimum FR point. I used an LR6 acoustic at 3 kHz for a very nice response. As for sound, it's more analytical than the BG Neo3PDR, cleaner than the PT2/YAG-20, but not quite as sweet as an Aurum Cantus true-ribbon. Detail and air are present and finite, and it has a broad horizontal dispersion with a more-than-typical vertical dispersion. Top end is well extended. If you love acoustic guitar pieces, these are for you!10W is plenty once L-pad compensated, but I used a 1A trip Polyswitch just in case.
