True “full range” floorstanding speakers

My Energy Audissey 5+2's are rated at 20hz-22khz and are semi large floor standing speakers with 4 built in and self powered subwoofers. I've done a frequency sweep and never heard such amazing low end. Music with real low end comes through with weight and impact. It's stunning to hear when it happens. I also find not a ton of musical material is in that region for the types of music I listen to be when it is... wow.

I’m pretty sure my Gammas can go to 15, I recently got the box but haven’t tried it yet. The 4 12’s are impressive on they’re own. I like quite a bit of old school rap and I have no problem shaking the entire house when I’m in the mood.
 
I just had my Vandersteen 3a Signature’s and JTR Captivator RS1 tuned to my new room (Using REW) they’re in and we got a measured in room response to 9hz in my 17X27 room (yes the foundation of my house was shaking) . Of course that was just tuning the system and I will probably never play music (unless a pipe organ) that reaches that low however, I can play any type of music and the bass is fast, tight and low.

The OPs very first sentence states this is not supposed to be about speakers with built in powered subwoofers.
The thread might as well be true "full-range" stand mounts if powered subwoofers are included. ;)

Just checking some of the speakers that I own that will go well into the 20hz range with less than 2 db swings they cross over very low, case in point is the Infinity Kappa 9's which has their bass drivers crossover at 80 hz. The Infinity QLS-1's use a dual voice coil bass driver and the specs are 18hz +/- 2db and their crossover point Is 200 hz. The QLS-1's bass is much better IMO than the Kappa's. I think it is primarily due to the larger cabinet size, and the Watkins driver. The Kappa's cabinets has less volume and the Kappa's use double the drivers in a small cabinet.

Don't know the specs of the Phase Linear Andromedas but the bass is very good on them, even compared to my Infinity's They do use a stand alone bass commode, with dual 12 inch drivers firing down which are mass loaded.

Having owned the Kappa 9s years ago, for a short time, they may have gone down to 20hz, but the amount of power needed at a very low impedance was one issue.

The other issue, they did not seem to "Like" to play really loud deep bass all that much. They sounded strained to me, like you were forcing them to do too much.

It's not impossible but it would be a lot more difficult than to build two cabinets per channel, because you're going to need two subenclosures (one for the subwoofer, one for the woofer, the former of which will probably be significantly larger than the latter), both tuned to that specific driver. It's also going to make them very heavy. It's been done - take a look at the Infinity Kappa 8 and 9 as two commercially-made examples (the midbass driver is an unusual dome rather than a cone, but it still uses a low-pass crossover frequency of 90hz, not bad for a subwoofer's high-pass cutoff point), but neither of those models go as low as you're looking to go, and they're already quite heavy.

The logistics of really loud deep bass and price, and size all go against ONE big speaker that can do everything well.

I think a few decades back, most realized a good sub or two can simply do this better, than two huge full range speakers.

I had some huge EV speakers years back that could sorta do 20hz with 18" woofers, but honestly even those, and they were HUGE, were not really as good as most decent subs today. I think speaker technology as far as deep bass has just allowed more excursion, more power and a smaller sized box that works even better than the things I had that were outright huge.
 
I can say owning Kappa 9’s and now the Gammas the difference in the same IMG woofers is amazingly different, where I always thought the 9’s are kinda flabby in the bass, in the Gammas they are a completely different animal, much deeper and tight, for me anyway they are near perfect. No sub needed with them IMHO.

I thought the same thing about my mains and adding subs, with my mains in room response was the low 20’s however, when I started adding subs and properly tuned them with my mains there was no comparison. In room response is below 20hz when called upon and have achieved 9hz with tuning and measured output, the biggest thing though is how much things have opened up , soundstage wider , tight bass, the low lows are defined much better. Although I would most likely never play any content that got that low (think pipe organs) I just don’t listen to that type music often, just about everything else is fair fair game and handled easily with my system.

Talon Khorus with the X upgraded crossovers 17hz-35khz, fastest most taught bass I have heard from a speaker at any cost. The dual 10’s in an isobaric configuration contributes to the low output as well as the cabinet, truly full range and exceptional sounding speakers.
