It is also a known fact that many PA subs and drivers will give up low extension in exchange for higher sensitivity and SPL. So depending on which PA sub you're looking at, you may need a true subwoofer (in the technical sense) to cover the low range below 40hz.
However, you cannot cherry pick a few PA subs that lack extension (even if they are "popular" models), use them in isolation without LF sub support, and then conclude that there are no PA subs that will work for HT.
First, if you are going to choose a PA sub that is only capable of mid-bass, then you obviously need to pair it with a true subwoofer to cover the LF range. For example, many people are using Growler/Captivator combos in precisely such a setup for their HT, with massive output and great success.
Second, if you don't want to mess with the additional crossover, and prefer to just employ a single type of sub for LF, there are pro audio subs out there that will do this for you as well. Since we're talking about JTR products here, google "JTR Speakers" and you will find that their tag line is "Professional Audio Speakers". What do you think the "Pro" in Captivator Pro stands for? It stands for "Professional Audio". It puzzles me that people would say that "a PA sub isn't comparable to a high quality home theater sub" like the Cap Pro. I got news for you. That Cap Pro you like so much IS a PA sub. It says so right there in its name.
It's most likely because you keep changing your position. First it was (paraphrased) "surely not possible for you to know if the Captivator products beat a PA sub without testing." Then it was "well, there's been no testing so Archaea can't know or even guess."
Then I clarified that my expectation of these pre-built subs is only in the context of HT usage specifically, with THD limits, not past 80hz, etc., because that is what the product in this thread is specifically designed for (and is the usage comparison originally made).
Then you changed your argument and said "they're fine for 40hz on up, with a different, real sub used below that" and you, out of the blue, cherrypicked a pro driver used in DIY
for similar applications, while disregarding my bandwidth restrictions to HT range that a person would use in comparison of HT subs, THD limits, inflated specs by the MFGs, etc.
Then I noted that you'd changed the goalposts and that you ignored the reiteration that my comment was limited to the comparison originally made: HT bandwidth use, pre-built HT subs compared only to pre-built PA "subs," THD limited, etc.
Now you've again said DIY provides a counterpoint to my argument, but the discussion was never about DIY. Then you claim that people are doing a combo of PA sub and HT sub, but that's entirely different than the original comparison and, again, was never part of the comparison. Then you change my argument and say I shouldn't cherrypick a few PA subs in a comparison without HT sub support for the lower octaves.
I'm just baffled, because I never did this; I only ever responded about the comparisons made by dlfromcanada. You're the one who changed it... Then you veer off subject again into a semantics argument about "pro audio" kit and crossovers for blending a HT sub and a PA sub. Why? I know a fair bit about it and I own a JTR product, so you don't have to pedantically educate me...
The discussion and comparison originally made is about THD-limited output in the normal HT bandwidth range from pre-built HT subs vs. a few mentioned PA subs, nothing else. If you want to argue that there are occasionally PA subs used in conjunction with HT subs in a scenario that might provide a good solution for somebody, that's fine and I don't think anybody here is going to argue with you. If you want to argue that some pro audio drivers can be used in specific DIY applications with good results in the HT bandwidth, go ahead. Again, I don't think anyone is going to argue with you. But those things are significantly outside the scope of the comparisons originally made by dlfromcanada and me, and are never things I have or would argue. Especially not in this product thread, where they're quite off topic.

That's awesome! Congrats!
