Series parallel connection. Not that large of a planar. There's larger.

Any updates / spec sheet? I'm curious how this fares against an aircirc.

Well here is some more info. I did some in living room RTA quickly that show the general response. And I did some careful measurements with the WTpro that give me a low end of the overall response as 94.5 one meter.

See the RTA below. No peaking or EQ of any kind is used. The tweeter is at and around 100 db/watt plus or minus 2 db. The overall response is plus or minus 2.5 db. The vertical scale is 5 db per major division.

Not to shabby for a few 5 inch drivers!

And believe me they can really kick butt on this horn. At the DIY Audio Ottawa show at ten feet away we were measuring 110.5 db on a good meter C weighted. I was measuring AC voltage with a meter using a peak hold function. We never topped 10 watts, and the cones never went past 2mm excursion. My point of vantage was right over top the right hand side speaker keeping an eye on the woofers.

What is most beguiling is that you have it all with this setup. As seen in the spec sheet, the distortion on these drivers is astonishingly low. On a horn they have a beautiful match between the low distortion of a horn loading the bass and the clean clear midrange off of the VWR's matched by the smooth high end off of the planar. A better match is hard to put together.
