Here is the Stein Music Topline XL Loudspeaker and Topline XL Subwoofer. I had never heard of the manufacturer or of the speaker before today.

The system is a pretty complicated-looking mix of horn + dynamic driver woofer tower, similar, it appears, to the larger Acapella designs. The woofer columns have a vertical array of forward-firing drivers, as well as a symmetrical pair of vertical arrays of angled-firing drivers.

Each subwoofer tower contains eight 18" drivers.

Did you like these? I thought there was a fair amount of potential that was unrealized.

Are they running cardioid?

The main towers are open baffle, this means that all those drivers are doing some kind of dipolar response but the exact pattern could be complicated...not a simple figure 8 like a typical planar dipole. Also the Horns are very much forward firing only. Then you have separate sub towers that are possibly in a push/pull isobaric or bipolar design (unclear from the boxes).

I don't think OB could run cardioid like that. You need a DSP to do it anyways. It's how the Kii3 is able to reduce room reflections without room treatment. While probably not used here, it would be a neat way to do bass drivers with horns.

It was open...I checked...curious like you.
