Crescendo posted cut sheets in post 773-775, and measurements around # 955-969.Has there been a conclusion to this thread? I would love to see any final plans
Any design is "playable".
If you skip building the cabinet as Crescendo did, it won't have the same response as he posted.
Lol , what I mean is that if we omit cone correction it will be not catastrophic to sound horrible peaky or just burn out the driver.
Martin (Xoc1) and others had much discussion about "cone correction" or what Tom Danley called a "stub" that he uses in many of his commercial TH designs.
Xoc1 did not include the "V" throat stub in his plans for the TH-18 as it became too much of a clone of the DSL TH-118.
Post #912, 921, 927, 987, etc. and #2343.

Anyway, driver "burn out" or "rocking the cone to death" are different catastrophic failures, thermal or mechanical .

OK, not quite sure if I understand since the specs in HR are different from the DS115, but with either specs I see nothing wrong other than its near 3:1 CR is pretty high for such a powerful output driver.
If wanting a more optimal alignment, its specs 'wants' a small ~46 Hz tapped pipe (TP) or horn (TH), which can in theory handle all 3400 W 'fast' transients.

Unfortunately I would say that sort of peaked response is what I have found when Simming the B&C DS series in existing tapped horn designs.
Hmm, need to keep in mind that HR doesn't account for any acoustic damping, so in reality its actual response will be somewhat smoother plus a TP, TH is basically a two octave alignment, so you'll need to EQ/XO it above 80-100 Hz, which just leaves some EQing to suit the needs of the app, if any.
In short, had you simmed a typical BR-like flat response it would be severely over-damped (rolled off on both ends of the gain BW), so in the future 'shoot' for ~ +/- 3 dB with equal amplitude peaks.
