Ah, yes. I can see the Eminence horn's six mounting holes now on the higher resolution monitor at work. The JBL/Pyle has eight, if I remember. The horn just looked a bit smaller, but I see that is due to it being set back a little.
Now even more intrigued- what does the centre channel do and why the different design... Look forward to reading your impressions, SkyWave.
