Since I never use a sub past about 120Hz, I don't bother thinking about response higher up in freq, .....other than making sure of no resonances, rattles, etc when cranking lol.
Sounds familiar...

Yes.is that SMAART ?
Although my preference also would be using subs below ~120 Hz, but many top cabinets that roll off well above that point- for instance the popular sealed co-ax 12" DSL SM-80 starts rolling off ~200Hz, -12dB at 100Hz.Thx Art, kind words.
Not sure what you are looking for, but maybe it's just the raw response... here it is... same 4m outdoor that's been the basis for all posts..

The unity/synergy horn uses a bms 4598he CD, four 4" 4NDF34 mids, and two 12" 12pr320 lows.what drivers are you using for mid and tweeter on the horn?

The upper response of course affects the crossover choice- the 120Hz LR24 is -15dB at 240Hz, a 120Hz LR12 would only be -3dB at 240Hz.
Mark,One of the design goals with this new guy, was to close down c2c spacing, with the 18"s and my syn horns.
It's now at about 1/4 WL to 147Hz.
With the prior PPSL sub, I could only xover at 90 Hz or below to achieve 1/4 Wl spacing down to -30dB.
My last post was unclear- the old sub has 10" more c2c vertical separation, but a more compact horizontal width, so off axis c2c horizontal separation is slightly less than the wider new sub.Vertical summations matter as much at low freq as do horiz, I think.
What's your take?
Yes. Big yes. That was one of the things I did not like about the huge sub carts that went with syn11....too damn directional. And again, never low-passed above 100Hz, and steep as heck.The larger front face of the new cabinet will make an increase in the forward directivity of both the sub and the top compared to the skinny old cabinet.
