Paul, what about using only 8-inch woofs in the AN3, and skip the 12-inch? 2, 3, or 4 8-inch should do the trick too, right…? I still remember the old Genesis V, one of my all-time favourites. No problem with the low-bass there from it’s 8-inch woofers…
Could be cost saving and easier to design…? Then use the 12-inchers in AN1 and AN2?
I just wondered because the new draft looks even taller than you first draft here (with at his time no sidefiring)
This is an interesting question. Made me recall the Ampeg SVT bass guitar amps that were composed of (8) 10” drivers. Many rock bass gods utilized that amp/cab. BASS FROM HELL (in a good way) ; )
As I recall, the cabinet was divided horizontally into quarters with (2) 10” drivers in each. Surprised the hell out of me when I found that out, as it put out more and bigger bass than a lot of cabinets with fewer, larger drivers. The cabinet was likely big enough to hold two 18” drivers, and sounded like it did.
My bass amp (Paul Jones Bass) often surprises fellow musicians with its tone and depth, despite (or more likely because of) its diminutive size - being composed of two 14x16x18” cabinets with four FIVE INCH drivers in each. You bring this to a session or gig and get some eye-rolling - until they hear it.
It’s a fraction of the size of the SVT, but the Ampeg was designed in the days of small PA’s and high stage volume. Now we see a lot more small amps that sound really good, are great for small rooms without PA, and mic well (or DI) for larger venues with PA.
Anyways - sort of a digression, but suffice to say I can attest to the “oomph” and tone potential of multiple smaller bass drivers. This does not mean that this sort of thing translates to audiophile speaker design. Just found your question interesting and sparked memories : )
Dan - please weigh in on this one…
The new draft is the same height as the old draft. It likely likely looks taller being placed with a photo background and a new 10" width versus the old 14" width.
As mentioned, In the rendering ear height looks to be aligned with the midbass. Is that correct?
yes, but shouldn’t it be shorter if bass drivers aren’t necessary anymore on the front?
I plan to fly out to hear all of the AN#s. As much as I love, love good deep bass, I will spend a lot of time focused on the AMT ribbons. I suspect that I will be blown away.
you will suddenly start to recognize many small changes or improvements of various comparisons first in the treble section due to the great resolution.
There are still bass drivers in the sides, it is just a bit hard to see in this specific photo. With the side firing 12" servo subs and space for amps down low, it still makes sense to keep the existing height of the AN1.
yes, seems so it’s necessary…
I also guess the sidefiring woofers mean some more cost has to go into the cabinet, as the larger sidewalls aren’t as stiff as the front and have to be reinforced at the bass chassis position.
Ear height is actually a bit higher than this, the upper of the two mid bass drivers is currently at around 24" off the ground. Ear height lies more towards the middle of the second AMT. The couch height and perspective can be a tad deceiving, but it is better than a pure grey background.
No, because we have to keep the tweeter and higher frequencies at ear level for a seated position.
On the AN1, where tweeters are available up to 7ft? wouldn’t even up to 4 feet be enough for ear level?
A multiplicity of high frequency drivers can be highly beneficial as vertical high frequency dispersion is very difficult to achieve.

Oh, sorry. No, they are the same size. Perhaps an optical delusion because they are thinner?
Me too, but I think Badbeef’s got it.
Great idea but I really believe no full range speaker system should have less than “real” bass and you simply cannot get what I consider to be real bass from anything less than servo controlled woofers with enough power and surface area to drop down near 20Hz. The GenV’s certainly didn’t and we often paired them with a Servo 12.

No. Ear height is aligned with the tweeter in the AN3 if you look at the three (did I post the three?).
Chet made a new animation of the AN-1 you can download here: https://www.dropbox.com/s/2tme2l6724kgm64/7-31-NarrowTall-Turntable2.mp4?dl=0
Pretty cool.

yes let’s surely true!
I think we have a misunderstanding: I understood from Paul, that the speaker has to have the same size as the one without sidefirering because tweeters have to be on ear level. And I doubted that, because tweeters are reaching nearly up to ceiling height anyway. I guess Paul misunderstood me, too. but we don’t need to dive into it further.
Paul with 4,000 watts of power each speaker what kind of electrical connectiondo you need to each speaker, it would seem a dedicated 15 map 120 circuit would not be enough.
