Found this reprint of an old interview with George Augspurger on Control Room Acoustics and Studio Monitor design (Recording Engineer/Producer (RE/P) Magazine, March / April 1974 issue).

There are so many factors involved with a loudspeaker in an arbitrary room, that it's very hard to be conclusive in this respect.

Ideally, you want a loudspeaker system that more or less 'gets the room out of the way'. A Synergy or MEH comes to mind.

camplo, I came across a post by natehansen66, he's also a member of this forum.

These are directivity plots of his dual AE TD15M in 3 cu ft sealed cabs, angled in to create about a 120° angle between the baffles. Ground plane measurement at about 12' (I believe this was done in order to mimic Augspurger monitors):

This is his thread on his DIY fiberglass 18" EOS waveguides.

I was just reading in that article, you shared, they angle the woofers in order to create wider dispersion in the mid range where beaming might otherwise exist.

It's rubbish.

In the Augsperger interview the JBL 2220 is referred to.

IMHO & FWIW, the "B" series is one of the best looking 15s ever.

OK, but why does this decide parallel Vs series wired? I mean in parallel you're using way more current, which heats up the VCs quicker, holds it longer = higher average and peak temps = higher effective Qts with the potential upside of lower inductance [Le] whereas the increased [Le] in series can be either a bonus or not depending on how much it has and the intended app.

Anyway, I'm old school, so my query was a many decades old rote response without remembering that 16 ohm rated amps are MIA in mainstream audio, so never mind. :P
