I am running a 3.5W 2a3 amp through AN-K speakers. They do a pretty darn good job on all but some of the late Romantic/early modern music with very large dynamic swings. My room is small about 4X4M, so I don't need the volume as much as I want my speakers to be able to keep up on the most dynamic passages.
Do the J's work for you at that?

If you want Dynamics, Horns are the way to go.....I would not have anything else.Go to the Hi-Eff Forum....

Horns aren't my cup of tea either. For high efficiency I prefer multiple direct radiators operated in unison.

Hello Cut-Throat,Have you had an opportunity yet to hear a Synergy Horn system?
Its a coherent point source horn that can reproduce a square wave.
Are you familiar with it?
I'm thinking that will become the "cats meow" when smart DIYers implement good designs based on the principle.
Various really good DIYers are working on it, right now.
One example I've referenced below, there will be others, its early.

Also this, the basic concept :

I run the OTO with the J/Spe in a 13 X 16 room and have no problems with grip at higher than I can take levels. Never get the knob past the 12 o'clock position.The OTO is 10 watts but 4.2 watts un-distorted (and I don't run them to distortion.
I do have them in corners however. The J is easier to drive than the E in the sense that it doesn't dip under 5ohms (the E drops to 3.6ohms). Both according to Hi-Fi Choice. SO while the E is more sensitive the J presents an easier load. I had the K in the same room but at that time I had a Sugden A48b at ~65 watts so the comparison isn't helpful.
The AN K is terrific - I wish I could hear one with foam surrounds and the AN J tweeter - I know that probably can't be done (at least the latter) but I remember a long while ago that Peter would have preferred the K woofer to be foam over rubber but they had to order them in such large quantities that it would not be feasible. I think the J and E breathe more - sound more dynamic and have more heft and resolution.
However, I found the J to take considerably more time to set-up to really get them bang on. The K being sealed perhaps made them much simpler.

"Never get the knob past the 12 o'clock position."
You do realize that the volume control position has no relation to available power output? It's like having a speedometer that goes up to 220 mph. That doesn't mean the car can actually go that fast.
What does affect the volume control position are: output level of the source (quite variable), preamp gain (quite variable---from 6 db to 32 db), power amp sensitivity (variable from 22 db to 32 db), and speaker efficiency (quite variable).
In my system, whem I switch power amps, I have to change the volume control significantly to maintain the same volume, perhaps from 10:00 to 2:00, yet the power is basically the same.
Deeply.

Umm the volume knob is used to control the power that is fed to a loudspeaker. The loudspeaker acts as a bucket that dips into the well (power). A high sensitive speaker will need less rotation on the knob than a LE speaker. However, since most speakers are in the 86db to 90db range and follow a similar design pattern then the customer needs to know how much power he has - especially if he does not own a meter and the amp doesn't have one.
The average person wants to know when he is out of power. Receiver makers were bad for this because they would have "high gain" amps that would be very loud with only a slight turn of the volume knob - this "tricks" the average customer into believing it is a "louder" amp because gee look at the 10'Oclock position it's deafening but on that other amp you have to turn it to 1'Oclock to get the same "perceived" volume level. The latter however may be a lower gain amp and may in fact play significantly louder overall because the first amp is already at full level before clipping.
I am aware that volume control and gain settings can be adjusted a variety of ways. What I should have originally said - was that I was not even near the amp's full output capability - Likely not even at the half way point. Of course it helps when the speakers and amps are mirror imaged at the design stage.
I disagree.....
That's hilarious! One of the all-time classics :)
Good point. My next amps will have a "12" setting, just to get that extra push.
Yes I am aware of this. Indeed when I first started out a number of dealers noted that a number of amps would be at full level at he 12 o'clock position while others as you say could be anywhere from 10-2. Taking the sensitivity of the speaker into account of course.
My understading though is that AN preamps/integrateds with AN speakers are full rotation designs. So you should be fine turning the dial to 3 o'clock - and that is how far the owner(Peter Qvortrup) was turning the dial at CES (Jinro amp). And the levels and bass depth did force the distributor David Cope out of the room. And this was undistorted so he really could have turned the dial a fair bit more. Speakers around 97db sensitive
Obviously on different speakers you would have to greatly compensate. I dislike some amps that have "early gain" because they can often be too loud too early if you have relatively sensitive speakers.
I've used the AN/J's in both a larger and a small room with an Audio Note 18 wpc SE amp and never felt lacking in power even with large scale orchestral music. The J's are at least 3 dB more sensitive than the K's, which is the equivalent of doubling your amp power. My impression of the J's vs. the K's is that the J's are a bit more open in the midrange which will be of benefit when pushing them with complex orchestral music.
Your room size (16 square meters) is at the lower range of recommended room size (12 to 40 square meters) for the J's so you should be OK. My experience with the J's in a small room just under 12 square meters was that they overloaded the room. In a 27 square meter room they sounded great.
My sofa is backed up on a wall. The speakers (K's) are in the corners. One corner is a half wall that protrudes out into the room about 2M and is about 1.5 m high. The other "corner" is a desk! However the room is "open" other than that to two adjacent living areas, all located in a long attic type space. My space is in the middle of three.
The sound is quite good with the K's. What I'd like is somwething like the K's, but with a compression driver on a tweeter waveguide (horn). I know such an animal is available in the form of the Pi-2 speaker kit. I started building the Pi-4s, but ran out of skill and was a bit intimidated by how big and ugly they were.
